Chemical Properties
Aluminum sulfate is an odorless, white, or off-white crystalline solid or powder. The compound is made by adding aluminum hydroxide to sulfuric acid. It's hygroscopic, which means it has the ability to absorb and hold water molecules from the surrounding atmosphere. It's also water soluble and not volatile or flammable. Aluminum sulfate is extremely acidic. When combined in solution with water its pH can be less than two, which can make it capable of burning human skin and corroding metal.
Application:
Water treatment, papermaking, printing and dyeing, pigment, fire fighting equipment, food additives, chemicals and wood preservation, medicine and Cosmetic,textile, etc.
1) In water treatment, its used as flocculants for purification of drinking water and wastewater treatment by settling of impurities by means of precipitation and flocculation.
Because, after dissolved in water, can make the small particles and natural colloidal particles coalesce into large floc,thus to remove them from water, so as the water and wastewater coagulant.
2) In the paper industry, used as a paper sizing agent of paper, to improving paper quality(reducing spots, enhance the water resistance, permeability, increase the hardness, etc.
3) In printing and dyeing industry, as anti-seepage agent mordant and printing.
Pigment industry for the production of chrome yellow and precipitant, at the same time, as solid color and fillers.
4). In fire protection industry, used as retention agent of foam fire extinguisher,making with baking soda and foaming agent.
5) In the food industry, used as a curing agent.
6) In wood industry, used as a preservative.
7) In Cosmetic and medicine industry, used as raw materials for antiperspirant cosmetics an astringent.
8) In textile Industry, it is used for color fixing in Naphthol based dyes for cotton fabric.
9) As raw materials, can used in the manufacture of synthetic gemstones and senior ammonium alum, other aluminate.
10) and also used as, and manufacturing alum, aluminum white raw materials, oil bleaching, deodorization agent, and raw materials of certain drugs, and so on.
