1、 Product name: Polyaluminum chloride
2、 Molecular formula: ALn（OH）mCL（3n-m） 0＜m＜3n
3、 Product trademark:
4、 Capacity: liquid 10000 tons/year ; Solid 20000 tons/year.
5、 Product characteristics: This product is an inorganic polymer flocculant based on aluminum oxide. Aluminum ion is the central ion of this polymer and is easily soluble in water. It can reduce the turbidity of source water through coagulation during water purification.
6、 Application: Mainly used for purification of drinking water and industrial water and treatment of industrial sewage. In addition, it is widely used in precision casting, paper making, leather making, pharmacy, brewing, ceramics, refractories, etc.
7、 Packaging and transportation: the liquid can be packaged in plastic barrels, and the transportation can be divided into pipeline transportation and tank car transportation; Plastic lined woven bags are used for packaging; During transportation, packaging damage shall be avoided during loading and unloading, and the transportation process shall be kept dry cool and protected from sun and rain.
8、 Storage conditions: Do not store with alkaline substances, and it shall be stored in a cool and dry place, which is not easily affected by moisture, and shall be protected from sunlight and rain.
9、 Quality standard: polyaluminum chloride for drinking water GB15892-2020;
Water treatment agent polyaluminum chloride GB/T22627-2022
