PAC [Chinese name] PAC (polyaluminum abbreviation) [English name] Polyaluminium Chloride, abbreviated as PAC [Formula] [AL2 (OH) LnCL6-n] m [technical standard] product quality in line with national GB15892- 2003 standard [appearance] golden yellow, khaki, brown, red granular / flake [Product Form] powdery solid liquid liquid solid performance index First grade alumina (AL2O3) Quality Chemical Name Index PAC Score /%≥10.029.0 basicity /% 40-9040-90 density (20oC) / (g / cm3) PAC basics [Chinese name] PAC (polyaluminum abbreviation) First grade liquid solid alumina (AL2O3) mass fraction of salt content /%≥10.0 29.0 degrees /% 40-9040-90 density (20oC) / (g / cm3) ≥1.12 1.12 water-insoluble /%≤0.2 0.6 PH (1% solution) 3.5-5.0 3.5-5.0 arsenic (As) /%≤0.0002 0.0006 mass fraction of lead (Pb) /%≤0.001 0.003 mass fraction of cadmium (Cd) /%≤0.0002 0.0006 mass fraction of mercury (Hg ) mass fraction /%≤0.00001 0.00003 hexavalent chromium (Cr + 6) mass fraction /%≤0.0005 0.0015 Note: The table liquid products listed in arsenic, lead, cadmium, mercury, hexavalent chromium, when the alumina content> 10.0% should be converted into the actual content of 10.0% alumina product, the magazine calculated index PAC role of poly (co) of aluminum chloride formula as follows: [AL2 (OH) nCL6-n] (n is 1 5.m≤10) basicity: B = n / 6 × 100%, its flocculation performance is as follows: strong electricity a, colloidal substances in water and function. b, hydrolysates of excellent bridge suspended solids in water adsorption. c, selective adsorption of dissolved substances. Poly (co) of aluminum chloride in water, the main form of [AL13O4 (OH) 24] 7+ performance [PAC] a, purified water is better than aluminum sulfate coagulant, water costs compared to low 15 -30%. b, fast floc formation, settling velocity faster, larger than traditional products such as aluminum sulfate processing capabilities. c, the consumption of water alkalinity less than all kinds of inorganic coagulant, which may cast vote or less alkaline agent. d, adaptation of the source water PH5.0-9.0 range can be aggregated. e, corrosion resistance, good operating conditions. f, the solubility is better than aluminum sulfate. g, handle less water salinity increases, facilitates the handling and high-purity water, the ion exchange system. h, the source water temperature adaptability than aluminum sulfate and other inorganic flocculants. Aluminum chloride, aluminum chloride patterns classification classification a, PAC undried liquid form, there is no dilution, loading and unloading easy to use, relatively cheap advantages, disadvantages tanker transport needs, increasing the unit transportation costs (per tons of solid equivalent of 2-3 tons of liquid) form after the b, solid PAC dry, convenient transportation advantages, no tanker, the disadvantage is the use of dilution also be required to increase the intensity of the work. [PAC Process classification] a, drum-type poly () aluminum chloride, aluminum content in general, high water-insoluble substance, used for wastewater treatment. b, frame-poly () aluminum chloride, aluminum content, low water-insoluble substance, used in sewage treatment and drinking process. c, spray drying poly () aluminum chloride, aluminum content, low water insoluble matter, dissolution speed. higher standards for drinking water and water treatment. [Poly (combined) use of aluminum chloride] a, urban drainage purification: river water, reservoir water, groundwater. b, industrial water purification. c, urban sewage treatment. d, industrial waste water and waste recycling useful materials, to promote recycling of coal washing waste water sedimentation, starch manufacturing starch. e, a variety of industrial wastewater treatment: wastewater, leather wastewater, wastewater containing fluoride, heavy metal waste water, wastewater, wastewater, coal washing wastewater, mine drainage, brewing wastewater, metallurgy wastewater, meat processing wastewater f, sewage treatment. g, paper sizing. h, sugar refining. i, cast molding. j, wrinkle-free cloth. PAC Photo Gallery k, catalyst support. l, medicine refining m, quick-setting cement. n, cosmetics raw materials. Poly (co) of aluminum chloride using Method 1, the dosage varies depending on the treated water, water purification general dosage is about: the liquid product 5-100 g / t, solid 20 - 25 kg / t (trade meter), may decide by a beaker test. 2, the preparation can be directly added to the water, add water according to the dosage and treatment capacity decisions, Stir, add water evenly. Poly (co) of aluminum chloride Note 1, water treatment chemicals from different manufacturers or different brands can not be mixed, and shall not mix with other chemicals stored. 2, slightly corrosive liquid and diluent, but lower than other types of inorganic flocculants. 3, effective storage products: liquid half solid years. The solid product tide still be used. 4, this product by adding reasonable, purified water meets drinking water standards.
