How to judge the quality of polymeric aluminium chloride pac?

　Polymeric aluminium chloride is an emerging water purification material, inorganic polymer coagulant, referred to as polyaluminium. Poly aluminium chloride (Poly aluminium Chloride) code name PAC. usually also known as water purifier or coagulant, the product is a product between AlCl3 and Al(OH)3, the quality of polymeric aluminium chloride depends on the comprehensive indicators of the product. 　　In the face of the mixed market, customers do not know how to choose the product, do not know how to judge the quality of polymeric aluminium chloride, good or bad, today to sum up, I hope it can help you. 　　Polymeric aluminium chloride PAC quality determines the price of polymeric aluminium chloride quality determination mainly has three indicators: aluminium trioxide content, salinity, water insoluble matter. The higher the aluminium content, the better the quality, the smaller the relative water insoluble matter. Salinity is adjustable. 　　1, the colour and quality of polymeric aluminium chloride PAC has a relationship. Polymeric aluminium chloride in general, from the appearance can be seen, divided into brown, earthy yellow, yellow, yellowish and white. The brown polymeric aluminium chloride belongs to the low grade, the earthy yellow polymeric aluminium chloride belongs to the middle grade products, and the yellow and white ones belong to the second grade products. The price increases in turn. 　　2, polymeric aluminium chloride plays a major role in the composition of aluminium oxide, judge the quality of the product depends on the content of aluminium oxide, life-grade water treatment of aluminium oxide quality score to reach 30% or more, industrial water treatment of aluminium oxide quality score to reach 27-29%. 　　3, the salinity of polymeric aluminium chloride, generally caused by polymeric aluminium chloride form of the basic components are OH ions, a measure of polymeric aluminium chloride OH ions in the index called salinity, usually the salinity is also defined as polymeric aluminium chloride molecules in the amount of OH and the percentage of the amount of Al, the general salinity should be within 40-90%. 　　4, the solubility of polymeric aluminium chloride is the polymeric aluminium chloride into the water after a few percent can melt away. The solubility of polymeric aluminium chloride for drinking water treatment is 99.7%, that is to say, 0.3% of water insoluble matter. The solubility of polymeric aluminium chloride for industrial wastewater treatment is 98%, which means 2% insoluble matter. That is to say, if it produces more than the proportion of insoluble matter, it means that the quality of this polymeric aluminium chloride does not meet. 　　5, polymeric aluminium chloride dissolved, there are insoluble matter deposited in the bottom of the pump box, time, more and more, and now are manually cleaned up, time-consuming and laborious, so you can judge the quality of the PAC product from the content of water insoluble matter. The main products of flocculant manufacturer Xinhuan Water Treatment are: White polyaluminium chloride (food grade), drinking grade polyaluminium chloride, industrial grade polyaluminium chloride, anionic polyacrylamide, cationic polyacrylamide, nonionic polyacrylamide, petroleum recycling polyacrylamide, oil recovery polyacrylamide, polyacrylamide, polymer flocculant polymer flocculation coagulant, polymeric ferrous sulphate, polymerized iron and aluminium chloride, and other water treatment chemicals.
