Aluminium sulfate

Aluminium sulfate (chemical formula Al2 (SO4) 3, type of 342.15), orthorhombic system white crystalline powder, the density of 1.69 g/mL (25 ℃) [1].In the paper industry as rosin gum, wax emulsion and other rubber precipitant, flocculant in water treatment, but also as foam fire extinguisher retention agent, alum production, aluminum white raw materials, petroleum decolorization, deodorant, some drugs raw materials.It can also produce synthetic gemstones and high grade ammonium alum.

Appearance and properties: white crystal, sweet taste;Solubility: soluble in water, insoluble in ethanol, etc.?Industrial products are gray-white flake, granular or blocky, with a pale green color due to low iron salt, and the surface is yellow due to oxidation of low iron salt.The coarse product is a porous gray-white fine crystal structure.?It is easily soluble in water, aluminum sulfate cannot be dissolved in pure sulfuric acid (just coexist), and is dissolved in water together with sulfuric acid in sulfuric acid solution, so the solubility of aluminum sulfate in sulfuric acid is the solubility of aluminum sulfate in water.

Not easy to weathering and loss of crystalline water, more stable, heat will lose water, high temperature will be decomposed into aluminum oxide and sulfur oxide.?Heated to 770 ℃ is decomposed into alumina, sulfur trioxide, sulfur dioxide and water vapor.Soluble in water, acids and bases, but insoluble in ethanol.An aqueous solution is acidic.Aluminum hydroxide is formed after hydrolysis.Basic aluminum sulfate can be formed by boiling an aqueous solution for a long time.Non-toxic, dust can irritate the eyes.

Packing: 25kg, 50kg, 1000kg, iron drum or as per customer's requirement.

25kg/50kg PP/PE bag; Jumbo bag or according to customers' requirements. 20-25MT will be loaded in per 20'FCL container
