Potassium alum dodecahydrate, also known as: alum, alum, potassium alum, potassium alum, potassium alum, potassium alum, is a double salt of potassium sulfate and aluminum sulfate containing crystal water. Colorless cubic crystal, the appearance is often octahedral, or with cube, rhombohedral dodecahedron form a cluster, sometimes with surface attached to the container wall and shaped like hexagonal plate, belonging to the α type alum compound salt, glass luster.
Water purification agent: potassium alum is widely used in the field of water treatment. It can adsorb the impurities suspended in the water and form a precipitate to clarify the water. It is a better water purification agent.
Fire extinguishing agent: can be used as fire extinguishing agent. The sulfur dioxide decomposed by potassium alum at high temperature can dilute the oxygen on the surface of the combustion, and the decomposed alumina is covered on the surface of the combustion, which can reduce the temperature of the combustion and achieve the effect of extinguishing the fire.
Medical use: Used as an astringent, such as used as a dampening drug, can be taken internally or externally, can treat jaundice, edema, excessive leucorrhea, diarrhea, aphthous ulcer, red eyes, eczema, scabies and other diseases. Some Chinese medicine practitioners use alum to treat diseases such as hyperlipidemia, duodenal ulcer and pulmonary hemoptysis.
Food additive: Used in the production of pasta food. For example, adding baking soda and potassium alum to flour makes fried churros fluffy and is a good leavening agent.
Industrial application: Used for preparing aluminum salt, paint, tanning material, clarifying agent, mordant, paper making, waterproofing agent, etc. For example, in the paper industry, potassium alum is used as a sizing agent in combination with rosin emulsions for paper sizing to improve the water resistance of paper.
Agricultural use: Used for seed disinfection, solid root seedling, strong rod full fruit and alkaline soil potassium fertilizer; Combined with green feed can be used for livestock disease control.
