Read： 912 Time：17months ago Source：Transform the World with Simplicity

Ammonium alum is a colorless transparent crystal, bitter taste, soluble in water, belong to inorganic compounds. Because of its stable chemical properties, it is widely used in many fields.

1. water treatment

ammonium alum is a kind of strong turbidity agent and settling agent, suitable for the treatment of suspended solids and solid particles in the water treatment process, the precipitation or floating up, to achieve water purification. At the same time, ammonium alum can also increase the hardness of water, effectively improve the chemical properties of water, making it more suitable for agricultural irrigation, industrial processing and so on.

2. metal treatment

ammonium alum in metal treatment also has a wide range of applications. Due to its passivation effect, a protective film can be formed on the metal surface to protect the metal from oxidation, corrosion, etc. At the same time, ammonium alum can also remove the oxide and rust layer on the metal surface, making the metal surface smoother and easier to process and use.

3. cosmetic

ammonium alum is widely used in the field of cosmetics. Because of its antibacterial and astringent effects, it is used in the manufacture of toners, creams, lipstick and other cosmetics. Ammonium alum can tighten the skin, shrink pores, but also make the skin more fresh, bright.

4. Textile

Ammonium alum can also be used in the field of textiles, often as a dye and fixative. Because of its strong affinity with the dye, it can improve the adhesion and color stability of the dye. At the same time, ammonium alum can also play a role in setting, making textiles more firm, luster, soft.

usage:

different uses require different usage methods. In general, ammonium alum needs to be dissolved before use. In water treatment, ammonium alum is generally used in dosing barrels and added to the water in a certain proportion to improve water quality. In metal treatment, ammonium alum can be applied to the metal surface with gauze or brush, slightly rub or scrub, and then rinse with water to remove the oxide and rust layer. In the field of cosmetics and textiles, ammonium alum is mixed with other materials, and the specific use method needs to refer to the specific product instructions.

summary:

ammonium alum is a multifunctional inorganic compound with high practical value. It has important applications in different fields and improves the quality of production and life. We need to choose the appropriate use method according to the specific use scenario, in order to better play its effect.
