Usage of Aluminum Sulfate

Aluminum sulfate is an inorganic compound with the formula Al2(SO4)3 and a molecular weight of 342.15. It is a white crystalline powder.In the paper industry, it can be used as a precipitating agent for rosin gum, wax emulsion and other rubber materials, as a flocculant in water treatment, and as a retention agent for foam fire extinguisher, raw materials for the manufacture of alum and aluminum white, oil decolorization, deodorization agent, raw materials for medicine, etc., and can also be used to manufacture artificial gems and high-grade ammonium alum.

Application of Aluminum Sulfate:

1. Water treatment agent

Aluminum sulfate is widely used in the field of water treatment. It can be used to purify water sources, removing suspended solids, colors and organic matter from the water. Aluminum sulfate has excellent flocculation performance, which can effectively collect and precipitate impurities suspended in water and improve water quality. In addition, aluminum sulfate can also be used to adjust the pH and hardness of water to stabilize water quality.

2. Paper and textile industries

Aluminum sulfate also has important applications in the paper and textile industries. In the paper making process, aluminum sulfate can be used as a deinking agent to remove the ink in waste paper, so that the paper can be recycled and recycled. In the textile industry, aluminum sulfate can be used as a fixing agent for dyes and pigments to improve the fastness of dyeing and color brightness.

3. Leather industry

Aluminum sulfate is widely used in leather industry. It reacts with the proteins in the leather to form stable compounds that solidify and soften the leather. Aluminum sulfate can also be used as a tanning agent to improve the softness and durability of leather and improve the quality and value of leather.

4. Building materials

Aluminum sulfate also has important applications in the field of building materials. It can be used as an early fortifying agent of cement, accelerate the solidification and hardening process of cement, and improve the strength and durability of cement. Aluminum sulfate can also be used as a curing agent for concrete to improve the compressive strength and durability of concrete.
