Introduction
potassium aluminum sulfate (Alum), also known as: alum, alum, potassium alum, potassium Lvfan, potassium alum, contain water of crystallization of potassium sulfate and aluminum sulfate salts. Colorless cubic crystals, glass luster. Density 1.757g/cm3, melting point 92.5 °C. 9 64.5 °C lost their crystal water molecules, 200 °C when the crystal water molecules lost 12, dissolved in water, insoluble in ethanol. Alum of the sour taste, cold, toxic. So have antibacterial, astringent, etc., can be used as medicine. Alum can also be used to prepare the aluminum salt, baking powder, paint, Tanning, clarifying agent, mordant, paper, waterproof agent.
Application
(1) Drugs
Alum, also known as alum, is a refinement of alunite products. Cold sour taste alum, has a strong convergence effect, Chinese medicine, insecticide detoxification alum, dampness itching, bleeding diarrhea, heat Phlegm effect. Recent studies have confirmed that alum also has anti-bacterial, anti-vaginal trichomoniasis and so on. Some traditional Chinese medicine to treat hyperlipidemia with alum, duodenal ulcer, tuberculosis, hemoptysis and other diseases.
(2) Food
In addition, alum is the traditional food improvers and leavening agents, commonly used for fritters, noodles, rice and other food additives production. However, due to the chemical composition of alum is potassium aluminum sulfate, containing aluminum ions, so excessive intake may affect body iron, calcium absorption components, leading to osteoporosis, anemia, and even affect the development of nerve cells. Therefore, some nutrition experts, to try to eat foods containing alum. Alum is the traditional purifying agent, has been widely used.
(3) Decoration
Alum is sometimes used to impersonate crystal. Alum crystal and crystal are very similar, but because of the hardness of the two different alum crystals will see a little water solution, the solution is milky white, and there will be crystal shedding.
(4) Other roles:as a purifying agent, as the extinguishing agent, as the expanding agent, as a drug. alum can also be used to prepare aluminum, paints, tanning, mordant, paper, waterproof agent.
