Is a water-soluble inorganic polymer between the aluminum chloride and aluminum hydroxide, between the two materials, typically represented by the formula Aln (OH) mCl3n-m represented; PAC white solid as a white powder, 10% aqueous solution is colorless transparent liquid. Mainly used for drinking water, industrial water, oil field injection water, cooling water and a variety of water (such as municipal sewage, oily wastewater, wastewater dyeing, papermaking wastewater, sewage and other mills) treatment; paper sizing precipitating agent, fire Adhesives; used in many fields tanning, pharmaceutical, food, cosmetics and precision casting. Third, white PAC product features 1, AL2O3 content, "29.5%. 2, the base is low, only about 50%, while the average degree of poly-aluminum base is about 90%. 3, water insoluble matter less, only about 0.3%, while the average poly aluminum water insoluble matter more than 2%. 4, white poly aluminum color pure white, except for AL + outside does not contain any heavy metals, aqueous solution of the water is clear and transparent the product, there is no color, while the ordinary aqueous poly aluminum color yellow or brown. 5, the iron content is low, with low soluble characteristics, likely to be used for projects such as oil and water separator; and container corrosion is minimal. 6, the mechanism of white PAC application: with a large positive charge, form stability polynuclear hydroxy aluminum complexes, can effectively promote flocculation, sizing. Fourth, white PAC Technical Index Name Index drinking non-potable liquid solid liquid solid Excellence Grade Excellence Grade Alumina (AL2O3) Content /% ≥ 10.0 10.0 30.0 28.0 10.0 27.0 Basicity% 40-8540-85 40-9040-90 40-9040-90 Density (20 ℃) ??/ (g/cm3) ≥ 1.15 1.15 - 1.15 - water-insoluble content /% ≤ 0.1 0.3 0.3 1.0 0.5 1.5 PH (1% solution) 3.5-5.0 3.5-5.0 3.5-5.0 3.5-5.0 3.5-5.0 3.5-5.0 ammonia nitrogen (N) content% ≤ 0.01 0.01 0.0002 0.001 0.0002 0.00001 0.0005 Arsenic (As) content% ≤ 0.0001 Lead (Pb ) content% ≤ 0.0005 Cadmium (Cd) content% ≤ 0.0001 mercury (Hg) content% ≤ 0.00001 hexavalent chromium (Cr6 +)% ≤ 0.0005 V. White PAC product uses the product can sterilization, deodorant, fluoride , aluminum, chromium, oil, turbidity, except heavy metal salts, with the exception of radioactive contaminants, with a variety of water purification process in a wide range of uses. White PAC range of applications: 1, purify drinking water, sewage. 2, industrial water purification, industrial wastewater, mining, oil field injection water, making water purification, metallurgy, coal, leather, paper, textile, steel, food plants and various chemical wastewater treatment. 3, the paper industry as a neutral sizing precipitating agent, retention and drainage of wet strength agent, anion capture agent. 4, in refining the coal industry for coal-water separation, the effect is very good. 5, as a bleaching agent in the clarification of the sugar industry in the brewing, beverage and other food areas were used as clarifying agent. 6, high-purity water. 7, producing a wide range of other industrial applications: bleaching and dyeing, cement accelerator, hardener precision casting, refractory agent, glycerin refining, wrinkle-free fabric, catalyst supports and tanning treatment, medicine refining, cosmetics manufacturing and other industries, waste water can be recycling and the like. Six PAC classification status of species by PAC: PAC PAC powder liquid crystal spray white PAC PAC PAC PAC drum-type polymerization ferric chloride powder by using a range of PAC: PAC food grade industrial grade aluminum using poly aluminum chloride in drinking water using poly aluminum industry, municipal sewage effluent using poly aluminum seven, white PAC use 1, water use should be based on a small test to elect good purification effect, put a small amount of PAC optimum point. PAC solution should be with the distribution with the use of non-potable water usage should be selected according to the actual situation. 2, the use of aluminum chloride solids, dissolved in water before adding to accompany dubbed about 10% of the solution, then diluted with water to the desired concentration of aluminum chloride, when dissolved in water before adding slowly carried PAC feeding, and continue stirring. Eight white PAC essentials 1, the product is acidic products, non-alkaline substances (such as bleach, lime, etc.) along with storage, otherwise the product will fail. 2, the solid product is easy to absorb moisture, should be placed in a dry, airy place for storage. 3, water treatment chemicals from different manufacturers or mix different brands can not, and must not be mixed with other chemicals stored. Nine, packaging, storage and transportation Songhai Chemical Co., Ltd. Jiangmen white PAC: Solid polyethylene bags lined plastic woven bag, 25KG / packaging; liquid is 50KG / barrel from; strictly prohibited and alkaline substances (such as bleach, lime, etc.), flammable, corrosive, there is a place to store items DU; PAC Shelf life: liquid half solid years (after the wet solid product can still be used).
