★★ spray poly aluminum chloride national standard GB15892-2009 standard by the General Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China together with China National Standardization Administration jointly issued, instead of the original national standard GB15892 - 2003 on April 8, 2009 and published in 2009 From September 1 implementation. This indicates that China's water industry in the standardization of international road has taken a new step. This standard corresponds to Japanese Industrial Standards JISK1475: 2006 "Water poly aluminum chloride" (Japanese version) and American Water Works Association standard ANSI / AWWAB408: 2003 "liquid poly aluminum chloride" (in English), and JISK1475: 2006, ANSI / AWWAB408: 2003 is not equivalent degree of consistency. PAC PAC PAC type and nature of the organic polymer has a natural polymer and a synthetic polymer into two categories. From the chemical structure can be divided into the following three types: (1) a polyamine type - low molecular weight PAC electrolyte; (2) quaternary ammonium type - change in molecular weight range, and has a high PAC; and (3) Polymerization chlorine aluminum copolymer - high molecular weight can be hundreds of thousands to millions, tens of millions, are milky or powder dosage form for sale, export PAC, use less convenient, but the good flocculation. According containing different functional groups dissociated charged particles in the case of type can be divided into PAC, PAC, PAC3 categories. PAC organic polymer macromolecules can take -COO -, - NH -, - SO3, -OH hydrophilic groups, etc., having a variety of chain structures, cyclic and the like. Because more reactive groups, high molecular weight, has to use less and less dross production, prosperity PAC, flocculation ability, easily separated floc, oil and suspended solids in addition to good effect and other characteristics, PAC factory, in processing refinery wastewater, other industrial waste, Chibi PAC, high suspended solids in waste water and solid-liquid separation type PAC PAC has a wide range of uses.
