Application

Coatings and paints

Ethylene diglycol monoethyl ether can be used as a solvent. In coating formulations, it can effectively dissolve resins, pigments and other ingredients. For example, in some water-based coatings, it helps the resin to be evenly dispersed, so that the coating has good fluidity and coating performance, thereby ensuring that the coating can form a uniform and smooth paint film on the coated surface.

Diethylene glycol ethyl ether helps to improve the drying speed of the coating. It can adjust the evaporation rate of the solvent in the coating to avoid defects in the paint film caused by too fast or too slow solvent evaporation, such as orange peel phenomenon (the solvent evaporates too quickly, the paint film surface is uneven) or too long drying time.

Ink industry

As an ink solvent, Ethylene diglycol monoethyl ether is used to dissolve resins, dyes and other ingredients in the ink to give the ink a suitable viscosity and fluidity. This is crucial for the transfer performance of the ink during the printing process, and can ensure that the ink is accurately transferred from the printing plate to the printing material (such as paper, plastic film, etc.), forming clear and bright patterns and text.

It can also improve the stability of ink, prevent the ink from precipitation and stratification during storage, and extend the shelf life of ink.

Cleaning and degreasing uses

Diethylene glycol monoethyl ether is an excellent cleaning agent component. Since Ethylene diglycol monoethyl ether has good solubility in grease, oil stains, etc., it can be used to clean oil stains on metal surfaces. In industrial production, such as mechanical processing, automobile manufacturing and other industries, it is used to clean processing oil, anti-rust oil, etc. on the surface of parts to ensure that the surface of parts is clean and tidy during subsequent processing or assembly.

It can also be used to clean electronic components. Its ability to dissolve oil stains can effectively remove grease and impurities on the surface of electronic components. Moreover, it has a certain volatility and can dry quickly after cleaning. It will not leave too many impurities on the surface of the components, thereby ensuring the performance of electronic components.

Textile printing and dyeing industry

As a textile auxiliary, diethylene glycol monoethyl ether can be used to improve the dyeing properties of fabrics. It can help dyes better penetrate into the fabric fibers and make dyeing more uniform. For example, in the dyeing process of cotton fabrics, polyester fabrics, etc., it is used as a dye cosolvent to improve the dyeing depth and uniformity.

It can also be used in the textile finishing process to adjust the performance of the finishing agent, such as as a solvent component in some softening finishing agents, so that the finishing agent can better adhere to the fabric surface, giving the fabric a soft and smooth feel.

3.Application

1. Chemical raw materials Because aluminum hydroxide can be produced on a large scale, the raw materials are sufficient, the product purity is high, and it is easily soluble in acid and alkali. Therefore, aluminum hydroxide is an important raw material for preparing aluminum salts, such as barium aluminate, aluminum sulfate, etc.

2. Flame retardant aluminum hydroxide powder is usually regarded as an ideal material for plastics, unsaturated polyester, rubber and other organic polymers because it has the functions of filling, flame retardant and smoke elimination and is non-toxic and harmless. Flame retardant filler. Flame retardant mechanism of aluminum hydroxide: When the temperature exceeds 200°C, aluminum hydroxide begins to endothermically decompose and release three crystal waters. Its decomposition rate is maximum at around 250°C. That is to say: this reaction is a strong endothermic reaction, which inhibits the increase in polymer temperature, reduces its decomposition rate, and only produces water vapor, without generating toxic and harmful gases.

3. Ceramic aluminum hydroxide is roasted at high temperature to obtain alumina, which has high thermochemical stability, thermal strength, creep resistance, dielectric properties and low thermal expansion coefficient. It is an important material for synthetic ceramics. During the ceramic synthesis process, aluminum hydroxide activates and controls the crystallization process, thereby controlling the phase formation of the composite material.

4. Sewage treatment aluminum hydroxide in water
Mainly Al(OH)4-, it can precipitate the toxic heavy metals in the sewage through co-precipitation and then filter it to achieve the effect of water purification. Aluminum hydroxide has a high specific surface area and can adsorb colloids, suspended solids, dyes, organic matter, etc. in sewage on the surface.

5. Catalyst carrier: During the preparation process of aluminum hydroxide, target products with different specific surface areas, pore volumes, pore structures and crystal structures are prepared by controlling the temperature, concentration and pH of the reactants. It can be effectively used as a catalyst carrier in various applications. Hydrogenation of saturated carbonyl compounds, preparation of fullerenes, etc.

6. Aluminum hydroxide in the papermaking industry has high whiteness, ultra-fine particle size, complete crystal form, and strong compatibility with whitening agents. Using it as an additive for coatings and resins can effectively improve the whiteness, opacity, smoothness and inkability of coated paper.
