Other 02020202 called PAC, polyaluminum, polyaluminum chloride chemical formula Al2Cln (OH) 6-NCAS registration number 1327-41-9; 101707-17-9; 11097-68-0; 114442-10-3; EINECS registration number 215-477-2 melt 02020202 point 190 (253kPa) easily soluble in water Watertight 02020202 degree liquid ≥1.12 outside 02020202 view yellow should be 02020202 water treatment 02020202 white polyaluminum chloride because it is called high-purity iron-free white polyaluminum chloride, or food-grade white polyaluminum chloride, compared with other polyaluminum chloride, it is a quality* product. The main raw materials are aluminum hydroxide powder, hydrochloric acid, and the production process is domestic* advanced Technique spray drying method. White polyaluminum chloride is used in papermaking glue applicator, sugar decolorization clarifier, leather tanning, cosmetics and precision casting and water treatment fields. 02 02 The raw materials of yellow polyaluminum chloride are calcium aluminate powder, hydrochloric acid and bauxite, which are mainly used in sewage treatment and drinking water treatment. The raw materials used for drinking water treatment are aluminum hydroxide powder, hydrochloric acid, and a little calcium aluminate powder. For the treatment of drinking water, * there are strict requirements for heavy metals, so both raw materials and production processes are better than brown polyaluminum chloride. Yellow polyaluminum chloride is generally produced by drum drying or spray tower drying. It has two solid forms: sheet and powder. 0202020202 ⒈ Urban water supply and drainage purification: river water, reservoir water, groundwater. ⒉ Industrial feed water purification. ⒊ Urban sewage treatment. ⒋ Recycling of useful substances in industrial wastewater and waste residue, promoting the settlement of pulverized coal in coal washing wastewater, and recycling of starch in starch manufacturing. ⒌ Various industrial wastewater treatment: printing and dyeing wastewater, leather wastewater, fluorine wastewater, heavy metal wastewater, oily wastewater, papermaking wastewater, coal washing wastewater, mining wastewater, brewing wastewater, metallurgical wastewater, meat processing wastewater, sewage treatment. ⒍ Papermaking glue. ⒎ Sugar liquid refining. ⒏ Casting molding. ⒐ The cloth is wrinkle-resistant. ⒑ Catalyst carrier. ⒒ Refined ⒓ Fast solidification of cement. ⒔ Cosmetic ingredients. 020202
