Jinyuan Chemical PAC [Chinese name] PAC (short poly aluminum) [English name] Polyaluminium Chloride, abbreviated as PAC [Formula] [AL2 (OH) LnCL6-n] m [technical standards] product quality in line with national GB15892-2003 standard [Appearance] golden yellow, khaki, brown, red granular / flake [Product Form] powdery solid liquid 1, poly (co) polymerization mechanism of aluminum chloride (co) is aluminum chloride An inorganic polymer coagulant, due to a larger polymerization of bridging hydroxyl ions and polyvalent anions produced molecular weight, high charge of inorganic polymer water treatment chemicals. The formula is as follows: [AL2 (OH) nCL6-n] (n is 1-5.m≤10) basicity: B = n / 6 × 100%, its coagulation performance is as follows: strong a, colloidal substances in water electric neutralization. b, hydrolysates of excellent bridge suspended solids in water adsorption. c, the selective adsorption of dissolved substances. 2, the performance a, purified water is better than * aluminum coagulants, water costs compared to 15-30% lower. b, floc formation quick settlement rate, larger than traditional products * aluminum processing capabilities. c, the consumption of water alkalinity less than a variety of inorganic coagulant, thus less time to cast vote alkaline agent. d, adaptation of the source water PH5.0-9.0 range can gather. e, corrosion resistance, good operating conditions. f, * superior solubility of aluminum. g, handle less water salinity increases, the system is conducive to high-purity water treatment and ion exchange. h, the source water temperature adaptability than * aluminum and other inorganic coagulant. Application: PAC is a currently the most widely used and important water treatment, are cationic inorganic polymer flocculant. 1, the PAC is mainly used for drinking water and industrial water purification, and industrial wastewater treatment. Is currently living water supply, industrial water treatment in the most widely used coagulant. 2, the PAC has a good flocculation, generated large alum, less dosage, high efficiency, quick settlement, the advantages of using a wide range. 3, PAC can be used at low temperatures, suitable PH value 5-9 after dosing without adding alkali, good flocculation, less sludge production. 4, the effective dosage of PAC products to 20-50mg / L. Liquid products can be directly metered dosing, solid products need to be dissolved in the pool match 10% -15% of the solution, the desired concentration measured at dosing. 5, PAC product can also be used to remove iron, manganese, chromium, lead, heavy metals, as well as water and oil-water contains fluoride, and so on, it can be used for a variety of industrial wastewater treatment. 6, PAC products to adapt to the treated water is strong, especially for high turbidity water treatment effect is more significant; coagulation effect remain stable at low temperature. 7, using the heavy metal content after PAC purify water color and iron, manganese and other low corrosive effect on small devices. 8, the use of PAC, there will be the problem of uneven mixing, dosing can be used after dilution. 9, PAC can be used with the weak cationic polyacrylamide, aluminum or a combination of ferric chloride and * for sludge modulation. Packaging and storage: water treatment agent PAC solid product bag lined with polyethylene plastic woven bag, weight 25kg. Water treatment agent PAC product should be stored in a cool, ventilated, dry dedicated warehouse. Storage and transportation process should keep the packaging intact, preventing heat moisture. Not with a total storage of toxic substances mixed operation.
