Lumpy Potassium Alum

Once potassium alum appears, many users do not know the product, so they always have questions. In order to better use the product, it is convenient to better meet the efficiency of the enterprise while using it, and then its related performance will be discussed. and functions are introduced.

Potassium aluminum sulfate dodecahydrate, also known as potassium alum;

Another name: potassium alum dodecahydrate, potassium aluminum alum dodecahydrate;

Appearance: colorless cubic crystal, often octahedral in appearance;

Application: as water purification agent, fire extinguishing agent, medicine, buffer; preparation of aluminum salt, paint, tanning material.

Chemical properties: The aqueous solution is acidic and hydrolyzed in water to form a colloidal precipitate of aluminum hydroxide.

Physical properties: colorless and transparent bulk crystal or crystalline powder, odorless, slightly sweet and sour taste. It loses crystal water by weathering in dry air, melts and drips in moist air, loses 9 crystal water when heated to 92·5°C, loses all crystal water at 200°C and becomes white powder. Easily soluble in water, slowly soluble in glycerol, insoluble in ethanol and acetone.

       The above is the introduction about what is potassium alum. According to its introduction, it can better help us choose and use products, effectively improve the use efficiency of products, and reduce improper use.

       use:

    ★ Light chemical industry: water purification, paper sizing, paint printing and dyeing, lake pigments, pharmaceuticals, paint making, leather making, fiberboard processing, film fixing and hardening, as well as for rubber and metallurgy, colored glass and other industries.

    ★ Food industry: food fermentation, vermicelli processing, pickling of aquatic products, food preservatives and food additives, etc.

    ★ Agriculture: seed disinfection, livestock treatment, root-fixing and seedlings, strong stems and full-fruits, and potassium fertilization in alkaline soils.
