What is Sulfamic acid CAS 5329-14-6?
Sulfamic acid CAS 5329-14-6 is a colorless, odorless, non-toxic solid strong acid. Its aqueous solution has the same strong acid properties as hydrochloric acid and sulfuric acid, but its corrosiveness to metals is much lower than that of hydrochloric acid. Sulfamic acid has very low toxicity to the human body, but it cannot be in contact with the skin for a long time, let alone enter the eyes.

Main Advantages
1. Because of its strong acid properties, it is also called solid sulfuric acid. It can replace sulfuric acid and make extremely pure crystals that are stable at room temperature. Sulfamic acid is very convenient to package, store and transport.
2. Aminosulfonic acid aqueous solution has a slow effect on the corrosion products of iron.
3. We have stock and can ship at any time
4.The production process of aminosulfonic acid is simple, the reaction is easier to control, the raw materials and equipment are easier to solve, the wastewater is also easy to handle, and the by-products can be effectively utilized
Application
1. Aminosulfonic acid aqueous solution has a slow effect on the corrosion products of iron. Some sodium chloride can be added to slowly produce hydrochloric acid, thereby effectively dissolving iron scale.
2. Sulfamic acid is suitable for removing scale and corrosion products on the surface of equipment made of iron, steel, copper, stainless steel and other materials.
3. Aminosulfonic acid aqueous solution is the only acid that can be used for cleaning galvanized metal surfaces. The cleaning temperature is generally controlled at no more than 66°C (to prevent the decomposition of aminosulfonic acid) and the concentration does not exceed 10%.
4. Aminosulfonic acid can be used as a reference reagent for acid-base titration in analytical chemistry.
5. Sulfamic acid is used as a herbicide, fire retardant, softener for paper and textiles, shrink-proof, bleaching, softener for fibers, and cleaner for metals and ceramics.
6. Sulfamic acid is also used for diazotization of dyes and pickling of electroplated metals.
Packing
Products are packaged in bag,25kg/bag
The product has a certain degree of moisture absorption and should be stored and transported in a sealed state in a low temperature, dry, cool and ventilated place.
