PVP polyvinylpyrrolidone with CAS 9003-39-8, is a linear polymer polymerized from N-vinylpyrrolidone (‌NVP)‌. ‌Its molecular formula is (C6H9NO)n, ‌where n represents the degree of polymerization, ‌that is, the molecular weight of the polymer. ‌PVP has specific chemical structure and physical properties, ‌making it widely used in many fields.

With the increasing severity of global environmental problems, reducing plastic pollution and promoting sustainable development have become urgent issues to be solved. Biodegradable plastics are of great significance to environmental protection because of their ability to degrade in the natural environment and reduce long-term plastic waste. Such materials can be broken down by microorganisms under certain conditions and eventually converted into carbon dioxide, water and biomass, reducing the damage to the ecosystem. However, biodegradable plastics still need to be further optimized in terms of mechanical properties and degradation rate.

‌ The application of polyvinylpyrrolidon  in biodegradable plastics is mainly reflected in its application as a modifier, which significantly improves the mechanical properties and degradation rate of the material by combining with other biodegradable materials. ‌

PVP is a synthetic water-soluble polymer with high solubility, adhesion and chemical stability. Due to its good film formation and chemical stability, PVP can be used as a modifier to combine with other biodegradable materials such as polyvinyl alcohol (PVA) to significantly improve the overall environmental performance of the material. For example, studies have shown that PVP can increase the hydrolysis rate of PVA, thus accelerating the biodegradation process of plastics‌. In addition, the introduction of PVP can also increase the toughness and elasticity of the material, making it more durable and reliable in practical applications‌.

PVP is used as a catalyst to accelerate the degradation of plastics. Compared with traditional plastic degradation technology, PVP catalytic degradation technology has the following advantages:

(1) Low cost: PVP, as a common and cheap polymer, has a relatively low cost of degradation reaction, which is convenient for large-scale application;
(2) Efficient degradation: PVP catalyst can effectively decompose plastics, accelerate the degradation process, so that the degradation rate can be improved, and the degradation effect is more significant;
(3) Environmental protection and sustainable: PVP catalytic degradation technology can achieve efficient degradation of plastics, and will not produce toxic and harmful substances, more friendly to the environment.

The combination of PVP and PVA is a typical successful case. PVA/PVP hydrogels prepared by γ-ray irradiation have demonstrated excellent biodegradability and antimicrobial properties, which makes them have wide application potential in medical and agricultural fields. Specific case studies have shown that the degradation rate of PVA/PVP hydrogels in soil is significantly increased, helping to reduce the environmental impact of agricultural waste‌.

The advantages of PVP as a modifier lie in its high solubility, excellent film formation and chemical stability, which enable it to enhance the mechanical properties and degradation rate of biodegradable plastics. However, PVP is not a fully biodegradable material on its own, so it needs to be combined with other biodegradable materials when used. In addition, PVP is heavily used in aquaculture as a polymer that is difficult to biodegrade and may cause long-term pollution to the environment.

In summary, the application of PVP in biodegradable plastics is mainly through combining with other biodegradable materials to significantly improve the performance and environmental adaptability of materials.‌

Octadecanethiol is an organic sulfur compound with the chemical formula C18H38S. Octadecanethiol is liquid clear, transparent and oily at temperatures above 35 degrees Celsius, and solid white wax at temperatures below 35 degrees Celsius.

Octadecanethiol is mainly used in electroplating additives, surfactants, etc., as a protective agent for nickel, copper, tin, gold, silver plating, improving salt spray and functionality. The coating layer is uniform and not easy to yellow, the surface washing ability is good, and the corrosion resistance of sulfide is strong. Octadecanethiol is a master of metal protection and has significant effects in protecting metals. When exposed to air, metals are often vulnerable to oxidation, which leads to corrosion. And octadecanethiol is like a “metal bodyguard”, it can form a protective film with the metal surface, blocking oxygen in the air, so as to effectively resist the damage of corrosion. It is like putting a strong suit of armor on the metal to protect it from the claws of corrosion.

Mercaptan is one of the widely used film forming agents in water-soluble gold and silver protective agents. In fact, research on the protection of silver faces dates back to the 1930s. There are two main protection methods adopted at the earliest. One is to use thiazole, imidazole, mertan and other organic substances to react with silver surface to form an organic film, which covers the silver surface to play a protective role. The other is the use of aluminum chloride, lithium chloride and other salts, using their own hydrolysis reaction, the formation of colloids to fill the silver gap, so as to achieve protection. In recent years, through the study of polymer chemistry, the selection of emulsifiers, and the screening of organic membrane components, the performance of silver surface protectants has reached a good effect.

In many experiments, dodecyl mercaptan, tetradecyl mercaptan, hexadecyl mercaptan and octadecanethiol  have been proved to be more effective mercaptan. Among the mature formulations, hexadecylmercaptan and octadecylmercaptan are more commonly used. UNILONG is a professional manufacturer of mercaptan series products such as octadecanethiol, specializing in the research and development and sales of plating brightener intermediates and plating additives, and independently producing silver plating brightener intermediates. In the application of metal environmental protection agent core materials, we have specially prepared special octadecanethiol  and 1-Docosanethiol according to the performance of protective agent film formation, which has shown excellent performance in new energy silver plating anti-vulcanization test and sulfuric acid boiling test.

De 1-Docosanethiol chemical formula is C22H46S. 1-Docosanethiol is liquid clear, transparent and oily at temperatures above 50 degrees Celsius, and solid white wax at temperatures below 45 degrees Celsius. 1-Docosanethiol can make up for the deficiency of octadecanethiol, the film natural curing fast, good surface washing, strong corrosion resistance. It has good application in coating and mechanical polishing protection of silver jewelry.

Of course, in addition to metal protection can play a vital role, as an important raw material for organic sulfide synthesis, it is also used in industrial production, daily chemical supplies and other fields.

For example, in cosmetics, octadecanethiol can be used as a beauty and skin care ingredient, with multiple effects such as antioxidant, moisturizing and soothing inflammation. At the same time, it is also a natural sunscreen, it has good light absorption properties, can effectively absorb ultraviolet rays, protect the skin from damage. In addition, octadecanethiol can also be used to prepare soft rubber products, so that it has better elasticity and wear resistance.

In addition, as a common organic sulfur compound, octadecanethiol is also widely used in the field of cleaning agents. Due to its strong solubility and decontamination effect, it is widely used in cleaning agents and descaling agents. In industrial production, octadecanethiol cleaners can be used to remove oil stains on machinery and equipment, candle stains and other difficult to clean dirt. In daily life, octadecanethiol cleaners can be used to clean surfaces such as kitchen utensils and bathroom facilities, effectively removing stubborn stains and maintaining cleanliness.

Finally, octadecanethiol is also very important in chemical experiments. Due to its low volatility and extremely low toxicity, it is ideal for many industrial and laboratory applications. In chemical synthesis, octadecanethiol can be used as a solvent to dissolve and catalyze the reaction substance, promote the reaction, accelerate the reaction speed, and improve the efficiency of chemical synthesis. In addition, it can also be used as an extractant to separate and purify organic compounds, thus playing an important role in chemical research and industrial production.

In short, the unique properties of octadecanethiol make it an indispensable and important substance in metal protection, chemical synthesis, industrial production and daily chemical products. With the continuous development of science and technology, we can foresee that the application of octadecanethiol in more fields will continue to expand and deepen.

We need to brush our teeth every day, then we need to use toothpaste, toothpaste is a daily necessities that must be used every day, so choose a suitable toothpaste is crucial. There are many kinds of toothpastes on the market with different functions, such as whitening, strengthening teeth and protecting gums, so How to choose the right toothpaste?

Now there are many kinds of toothpaste, usually different toothpaste will have its different effects, in fact, whether it is cheap or expensive toothpaste, the purpose is to help clean teeth, therefore, when we buy toothpaste, do not only look at the price, think that the expensive must be good, expensive out is some additives, such as some anti-allergy, hemostatic, whitening and other ingredients. In fact, the main component of toothpaste is the friction agent, the common friction agent are, calcium hydrogen phosphate, calcium carbonate and calcium pyrophosphate, of which, calcium carbonate friction is relatively strong, generally used to clean teeth of tea and smoke stains.

However, some people like to choose fluoride toothpaste, especially every time the tooth decay tormented sleep. It is an indisputable fact that toothpaste contains a small amount of fluorine, which can play a role in preventing dental caries. So you can use fluoride toothpaste to prevent. When it comes to fluoride toothpaste, the ingredients that have to be mentioned are sodium fluoride and sodium monofluorophosphate.Let me show you the difference between the two.

What is sodium monofluorophosphate？

Sodium monofluorophosphate is an inorganic compound, referred to as MFP, CAS number 10163-15-. MFP has the chemical formula Na2PO3F, is a white crystalline powder, soluble in water. Sodium monofluorophosphate is broken down by acid or salivary enzymes in the mouth, releasing fluoride ions, which react with crystals on the surface of tooth enamel to form fluorapatite, thereby enhancing tooth resistance and inhibiting dental caries. Sodium monofluorophosphate is widely used in food additives, toothpaste, metal cleaners, special glass, skin care cosmetics and other fields, especially in toothpaste, it is used as one of the main components of anti-caries toothpaste. It is generally one of the toothpaste formulations, has basically replaced sodium fluoride in some products, and has gained an advantage in competition with tin fluoride.

Sodium monofluorophosphate is an excellent anti-caries agent and tooth desensitization agent, the conventional content of fluoride in toothpaste is 0.10– 0.12%, but also has a strong bond tooth function, sodium fluoride is an anti-caries agent, mainly used as a fluoride toothpaste additive, the conventional content of fluoride in toothpaste is 0.7– 0.8%, Fluoride in toothpaste can be combined with minerals in the mouth to form fluorapatite, strengthen the protective layer of the tooth surface, high fluoride content, better anti-decay effect, monofluorophosphate compared with sodium fluoride, monofluorophosphate contains more fluorine, so sodium monofluorophosphate anti-decay better.

In fact, sodium fluoride and sodium monofluorophosphate are two different compounds, and they have different chemical structures and application fields.

What is sodium fluoride？

Sodium fluoride (NaF) is an inorganic compound with the formula NaF. Its main applications include as phosphating promoters, agricultural pesticides, sealing materials, preservatives and so on. Sodium fluoride is also used in the medical field to prevent cavities and strengthen teeth, but its role is mainly to provide fluoride, rather than through the mechanism of sodium monofluorophosphate.

In summary, although sodium fluoride and sodium monofluorophosphate overlap in some applications, their mechanisms of action and specific applications are different. Sodium monofluorophosphate has a superior effect in dental care, so it is more commonly used in dental care products such as toothpaste.

At present, there are different toothpastes on the market, the common ones are: fluoride toothpaste, anti-inflammatory toothpaste and anti-allergy toothpaste, you can choose according to your own needs, maintain oral health, as long as you choose the toothpaste on the line. Here I believe that everyone knows how to choose toothpaste.

Preparation method

1. Add a certain amount of water to a 1000mL beaker, add solid soda ash at room temperature, stir for 30 minutes to fully dissolve it, and then add chloroacetic acid for neutralization. The neutralization reaction of chloroacetic acid is exothermic, accompanied by the release of a large amount of carbon dioxide gas, the reaction is relatively drastic, in order to control the temperature of the neutralization reaction (the temperature is too high, the temperature is too high, the temperature is too high, the temperature is too high. Chloroacetic acid will undergo hydrolysis reaction to produce hydroxyl carboxylic acid) and prevent foam overflow during the reaction, the addition rate of chloroacetic acid is slow, and its dosage depends on the pH value of the solution; After the solution becomes clear, pour it into a three-port flask and put it into an electric heating water bath for heating reaction. When it reaches a certain temperature, add sodium thiosulfate crystal, stir and heat up to 85℃, and react at this temperature for 40 minutes to obtain salt. After the temperature continues to rise to 95℃, the strong alkali thioglycolating agent solution is added, the reaction is about 40min, the heating and stirring are stopped, the natural cooling is done, and the transparent sodium thioglycolate product can be obtained after purification.
2. Add 185g sodium chloroacetate,29g isopropyl xanthoxanthate and appropriate amount of water into a 500ml four-mouth flask, react at 75℃ for 2h, then drop to room temperature, and slowly add 5% excess monoethylamine into the four-mouth flask with stirring. After the addition, the temperature is raised to 70℃ and the lh is kept warm. At this time, the reaction system changes from transparent to yellow cloudy, and finally becomes brown cloudy liquid. Stop stirring, stand stratification, the upper layer is yellow transparent liquid, which is ethylthiamine vinegar, said the mass is 77.1g, the purity is greater than 96%, the isopropyl alcohol mass fraction is less than 3.0%; The lower layer is dark red alkaline waste liquid, containing sodium leucyl acetate, sodium chloride, etc., which can be directly used as flotation agents.

Toepassing

1. Application in the separation of copper and lead Sodium thioglycolate, as a non-toxic, small molecule inhibitor, has a good inhibition effect on chalcopyrite, and can be applied in the separation process of copper-lead mixed concentrate to achieve the separation of copper and lead. Factors such as the dedrug effect, the type and dosage of the collector, the pulp p and H value, and the amount of sodium thioglycolate during separation have important effects on the separation effect of copper and lead, but the amount of sodium thioglycolate is the most important influencing factor. When the amount is appropriate, the separation of copper and lead can be better achieved. When the amount is too large, sodium thioglycolate can inhibit both of them. Inhibition mechanism: The infrared spectral curves of sodium thioglycolate after the interaction with chalcopyrite and galena were bifurcated. After washing, the absorption valley of these characteristic groups became weak but did not disappear completely, which proved that sodium thioglycolate coexisted with physical adsorption and chemisorption on chalcopyrite and galena surface.

2. Activated sphalerite with copper sulfate in high pH slurry, lime as an inhibitor of pyrrhotite and pyrite, supplemented by sodium thioglycolate, can effectively achieve zinc-sulfur separation, industrial production test obtained grade 45.10% zinc concentrate, operation recovery of 94.39%. Sodium thioglycoacetate is a medium toxic agent, which has a good inhibition effect on pyrite and pyrrhotite, and can completely replace highly toxic cyanide to achieve cyanide-free separation process of zinc and sulfur, which not only ensures the production index of zinc concentrate grade and recovery rate, but also can meet the national environmental protection requirements. Sodium thioglycolate has little inhibitory effect on sphalerite, and has maintained good production index since the use of sodium thioglycolate.

At present, according to the needs of customers, we have opened a new production line, all using high-purity imported raw materials production, sodium thioglycolate widely used in hair removal (such as leather, human body), hair ironing and dyeing agent, solid and liquid media preparation.

What is Sodium Monofluorophosphate？

Kaliummonofluorofosfaat is referred to as “SMFP” is a chemical substance, CAS 10163-15-2 white powder or white crystal, easily soluble in water, strong hygroscopic, at 25 degrees water dissolution is no side effects and no corrosion. Sodium monofluorophosphate contained in toothpaste is an excellent anti-caries agent and tooth desensitization agent. The conventional content of Sodium Monofluorophosphate in toothpaste is 0.7-0.8%, and the conventional content of fluorine in drinking water is 1.0mg/L. Sodium monofluorophosphate in aqueous solution has obvious bactericidal effect, and has obvious inhibitory effect on melanomycin, staphylococcus aureus, salmonella and so on. Sodium monofluorophosphate is widely used in toothpaste additives, concrete corrosion inhibitors, food, medical and other aspects.

Is sodium monofluorophosphate good for your teeth?

Sodium Monofluorophosphate is an inorganic compound used in toothpaste to prevent tooth decay and improve tooth sensitivity. The specific analysis is as follows:

Sodium Monofluorophosphate is widely used in fluoride toothpastes, which can promote tooth remineralization and prevent tooth decay. It has a good effect on people with sensitive teeth and will not irritate teeth after use. However, sodium monofluorophosphate has a certain toxicity, the content of sodium monofluorophosphate in toothpaste is 0.7%-0.8%, and generally a small amount of ingestion will not have any effect. If swallowed for a long time, it may lead to fluorosis, and may also cause tooth deformity, softening, loss of luster, etc., resulting in dental hypoplasia.

What are the risks of sodium monofluorophosphate?

Fluorine exists widely in nature and is one of the essential trace elements for human body, mainly accumulated in teeth and bones. Proper fluoride is necessary for the human body to maintain the normal development and calcification of teeth. The discovery that fluoride can prevent dental caries is arguably one of the greatest contributions of preventive oral medicine to mankind in the 20th century.

In short, fluoride ions can inhibit tooth demineralization, promote tooth mineralization, and enhance tooth resistance to acid; Fluoride also reduces the incidence of dental caries by affecting the metabolic activity of caries-causing bacteria. Therefore, moderate use of fluoride can effectively prevent tooth decay, which is the result of hundreds of clinical studies over decades. The commonly used fluoride in the mouth is sodium fluoride, sodium monofluorophosphate, stannous fluoride, etc., such as fluoride toothpaste, fluoride mouthwash, fluoride foam, etc.

The easiest and most common way to protect your teeth with fluoride is to brush your teeth twice a day with fluoride toothpaste. Many domestic and foreign authorities, such as the World Health Organization (WHO), the Chinese Dental Association have affirmed the role of fluoride toothpaste to prevent dental caries, but also clearly pointed out the safety and effectiveness of fluoride toothpaste.

What is the function of sodium monofluorophosphate?

Sodium Monofluorophosphate is widely used as toothpaste additive, concrete corrosion inhibitor, food, medical and so on.

1. Application in toothpaste

SMFP is the most widely used toothpaste additive in the world, and is an excellent anti-caries agent and tooth desensitization agent, with a mass fraction of 0.7% to 0.8% in toothpaste. There are two main categories according to the ingredients: care toothpaste and biological toothpaste.

Nursing toothpaste: nursing toothpaste has the functions of preventing caries, desensitizing, anti-inflammatory and preventing tooth stones, etc. The grass coral total effect nursing toothpaste developed has this multi-effect function. The most important thing for the effective prevention and treatment of dental and periodontal diseases is to eliminate bacteria harmful to dental health in the mouth, and herbal extracts have been widely recognized in preventing and eliminating general inflammation of the gum and oral mucosa. The fluoride in Grass coral Total effect care toothpaste has the function of antibacterial and bactericidal. According to relevant studies, low concentration of fluoride ions (0.8% sodium monofluorophosphate in grass coral) has a better antibacterial effect. Fluoride is used as an additive to prevent caries. It not only has a health care effect on acid-resistant desensitization of teeth, but also acts with tooth enamel to form fluorapatite on the surface of tooth enamel, which improves the hardness of tooth enamel.

2) Biological toothpaste: Biological toothpaste is the addition of toothpaste to the biological body has a specific active function of the substance, the current biological toothpaste mainly contains enzyme preparations, antibody preparations and other biological active preparations. The toothpaste containing enzyme preparation mainly contains protease and glucanase. Proteolytic enzyme toothpaste can promote the rapid hydrolysis and break of the long chain of protein polypeptides, make the food residue attached to the tooth surface soft, easy to clean the mouth, and has the function of softening blood vessels, can make the inflammation and edema of the gum subside, and the phenomenon of tooth bleeding has been significantly improved or eliminated.

Glucanase helps remove tartar. Toothpaste containing antibody preparation is generally divided into: toothpaste containing milk antibody and toothpaste containing genetically modified preparation. Milk antibody toothpaste is to extract antibodies from milk, and it is added to the toothpaste to fight against a certain disease. The toothpaste containing transgenic antibody preparation is to add the product of human oral disease vaccine gene in the transgenic horse bell tuber into the toothpaste, which can produce the corresponding effect of preventing oral diseases. The fluorine in sodium monofluorophosphate is stable, and the fluorine in one year is maintained at 84.4%, which effectively ensures the caries prevention effect. Its pH value is 5.5 ~ 6.5, which is neutral. And good compatibility with abrasives, these advantages determine that sodium monofluorophosphate is very suitable for toothpaste additives, has been in mass production in China. The anti-caries effect of fluoride toothpaste was observed in Beijing Stomatology Science Center for two and a half years, and the caries decreased by 42.95%.

2. Application in food

1) SMFP used as a food additive: From long-term clinical trials, it is known that sodium monofluorophosphate is better than other common fluoride raw materials (such as sodium fluoride) as a source of fluorine. Sodium monofluorophosphate can be used as a food additive to increase food nutrition, but if it exceeds the standard, it is unsafe. Sodium monofluorophosphate is added to foods, and 0.25 to 5mg of fluorine can be added every day, which is equivalent to the intake of 2.5 to 16mg sodium monofluorophosphate. According to the data, it is not safe to consume sodium fluoride (1.7 to 14mg) and phosphate (1.1 to 8.8mg) every day. In Europe, the amount of additives in food is generally below the maximum limit. For adults, eating 2mg of fluorine-containing food per day will not exceed the standard. Therefore, we should pay attention to the safety of sodium monofluorophosphate while enhancing the nutritional value of food.

2) SMFP used as chewing gum material: Chewing gum has always been favored by the public. But the current chewing gum does not have caries prevention, desensitization, bacteriostasis, anti-cold and other health functions. Although the average medicated toothpaste has one or more effects, it cannot replace the chewing function and taste of chewing gum. In 1998, Li Guohua developed a chewing gum with multiple effects, which added 0.5% sodium monofluorophosphate, so it has a good anti-caries effect.

3. Medical applications

1) SMFP used to regulate menopause: female lipid and lipoprotein metabolism Sodium monofluorophosphate can be used to regulate lipid and lipoprotein metabolism in postmenopausal women.

2) SMFP used to increase bone mass and alleviate osteoporosis: Sodium monofluorophosphate promotes osteoblast differentiation and diffusion while promoting bone mass increase, which is caused by fluorine inhibiting growth factors in acid phosphatase. MFP can perform its function through other signaling mechanisms. Although sodium fluoride also has the function of increasing bone mass, MFP increases bone mass more when consuming equal amounts of MFP and NaF. Sodium monofluorophosphate can increase bone mass and relieve osteoporosis, but it does not change the mineralization of bone tissue.

4. Used as a corrosion inhibitor:

When steel bars corrode, a series of protection and repair methods can strengthen the structure of concrete, and corrosion inhibitors are the most attractive alternatives. MFP as a rust inhibitor can slow down the corrosion of rebar.

In het verleden, vanwege de achterwaartse medische kennis en beperkte omstandigheden, hadden de mensen weinig besef van de tand bescherming, en veel mensen niet begrijpen waarom tanden moeten worden beschermd. De tanden zijn het zwaarste orgaan in het menselijk lichaam. Ze worden gebruikt om te bijten, bijten en voedsel te malen, en helpen met de uitspraak. De menselijke voortanden hebben het effect van scheuren van voedsel, en de achterste tanden hebben het effect van het slijpen van voedsel en het voedsel dat bevorderlijk is voor de spijsvertering en de absorptie van de maag na het volledig wordt gekauwd. Daarom, als de tanden niet goed, het is zeer waarschijnlijk van invloed zijn op onze gastro-intestinale problemen.

Bovendien, de tanden zijn niet goed, maar ook pijn veroorzaken, zoals het gezegde gaat: "kiespijn is geen ziekte, het doet echt pijn", omdat onze tanden zijn dicht begroeid met wortels van dezelfde tandheelkundige zenuwen, pijn door deze dichte kleine tandheelkundige zenuwen transmissie. Een ander punt kan niet worden genegeerd, slechte tanden zal ook een slechte adem, serieuze mensen zullen van invloed op de interpersoonlijke communicatie, dus het is zeer belangrijk om de bescherming van de tanden!

Kaliummonofluorofosfaat voor tandpasta industrie wordt gebruikt als een anti-cariës agent, desensibilisatie additief, en ook gebruikt als bactericide en als conserveermiddel in tandpasta verwerking. De conventionele inhoud in de tandpasta is 0.7-0.8%, en de conventionele fluor inhoud in het drinken van water is 1,0 mg/L. De waterige oplossing van kaliummonofluorofosfaat heeft duidelijk bacteriedodende werking. Het is duidelijk remmend effect op melanosomin, staphylococcus aureus, salmonella, etc.

Fluoride kan worden toegepast in een verscheidenheid van manieren in de tandheelkunde. Naast gefluoreerde producten voor de dagelijkse mondhygiëne, zoals tandpasta en mondwater, er zijn speciale tandheelkundige behandelingen beschikbaar in de vorm van gel en lak, onder andere bij de tandarts. De meest voorkomende manier is de toepassing van fluoride plaatselijk door je tanden poetsen per dag met fluoride tandpasta die beschermt het glazuur van de bacteriën in uw mond. Het is belangrijk om gebruik tandpasta met fluoride in uw dagelijks poetsen van de kindertijd. Op deze manier, tanden genieten van een betere gezondheid en bescherming tijdens hun leven, het verminderen van het risico van tandbederf en andere orale ziekten.、

Door de jaren heen, de wereld heeft onderzoek gedaan naar de anti-cariës effect van kaliummonofluorofosfaat gebruikt in tandpasta en de toxiciteit van het menselijk lichaam, hoewel na herhaald onderzoek en veel discussies, de uiteindelijke conclusie is dat kaliummonofluorofosfaat is veilig voor het menselijk lichaam in de anti-cariës aspect en kan worden gebruikt met de vrede van de geest.

We zijn niet onbekend met hars, dus wat is het verschil tussen gehydrogeneerde hars en hars? Hoe moeten we kiezen voor deze twee producten? Laten we eerst eens kijken naar de verschillen tussen hen.

De verschillen in eigenschappen tussen gehydrogeneerde hars en hars

Gehydrogeneerde hars, ook wel bekend als demethylated rosin, is een product dat wordt verkregen door hydrogenering reactie van colofonium na gedeeltelijke verwijdering van methylgroepen. Door de toename van de C-H bindingen in gehydrogeneerde hars, deze stof heeft een betere stabiliteit en weerstand op hoge temperatuur, en het smeltpunt ligt ook relatief hoger. In contrast, de gewone hars bevat meer methyl groepen, waardoor het gevoelig voor volatilization en produceren van irriterende geuren. Gehydrogeneerde hars heeft een relatief geen probleem.

Verschillen in het Gebruik van Gehydrogeneerde Hars en Hars

Door de uitstekende eigenschappen en stabiliteit, gehydrogeneerde hars wordt op grote schaal gebruikt in de velden, zoals inkten, coatings, lijmen en rubber. Hars wordt voornamelijk gebruikt in de productie van dagelijkse benodigdheden, zoals aromatherapie en pixels, alsmede op het gebied van traditionele Chinese geneeskunde en capsules voor de farmaceutische industrie.

Verschillen in productiemethoden tussen gehydrogeneerde hars en hars

Het productie proces van gehydrogeneerde rosin vereist het verwijderen van methyl groepen en hydrogenering reacties, terwijl hars productie wordt verkregen door middel van de stappen zoals extractie, destillatie, en de koeling van vloeibare hars. Daarom is het productieproces van gehydrogeneerde rosin is relatief complex.
