Poly Aluminium Chloride 99% Colorless or yellow resinous solid

Polyaluminum chloride is a kind of water purification material, inorganic polymer coagulant, also referred to as polyaluminum, English abbreviation for PAC, due to the bridging effect of hydroxide ion and polyvalent anion polymerization and production of high molecular weight, high charge inorganic polymer water treatment agents. In form can be divided into solid and liquid two. Solids are divided into brown, beige, golden yellow and white according to color, while liquids can be colorless and transparent, slightly yellow, light yellow to yellowish brown. There are also great differences in the application and production technology of different colors of polyaluminum chloride.

White polyaluminum chloride also known as polymer coagulant. It is a fine white or milky powder powder made by spray drying process of aluminum hydroxide powder and high purity hydrochloric acid. It is easy to melt in the air. White polyaluminum chloride has replaced aluminum sulfate as neutral sizing precipitator in paper industry.

PAC spray drying due to the advantages of spray drying stability, wide water, fast hydrolysis rate, strong adsorption capacity, large alum formation, dense precipitation, low turbidity of the outlet water, good dehydration performance, under the same water quality, spray drying PAC PAC dosage is reduced, especially in the case of poor water quality, Compared with roller drying polyaluminum chloride, spray drying product input can be reduced by half, which not only reduces the labor intensity of workers, but more importantly, reduces the water production cost of users.

In addition, the use of spray drying products can ensure safety, reduce water accidents, drinking water for residents is very safe and reliable. Polyaluminum chloride, abbreviated as high efficiency polyaluminum chloride, or high efficiency PAC. Using the most advanced production technology, the use of high - quality raw materials reaction polymerization. Bamboo Qing all quality indicators have reached or even exceeded the national standard GB15892-2009 requirements. Polyaluminium chloride is produced by spray drying process. Therefore, it can also be called high efficiency spray drying polyaluminum chloride. PAC product features: Kaibi source brand PAC products have fine powder, uniform particles, easy to dissolve in water, good flocculation effect, efficient and stable purification, small dosage, low cost. Suitable for drinking water purification, urban water supply purification and industrial water supply purification; Suitable for all kinds of turbidity of the source water, PH application range, alum formation, fast, fast settling speed.

PAC polyaluminum chloride water insoluble matter: the use of plate and frame press filtration technology, so that the solid water insoluble matter mass fraction below 0.3%, liquid water insoluble matter mass fraction below 0.1%, can ensure the user's pipeline smooth, while improving the use of drugs, and natural sedimentation method is not up to. Polyaluminum chloride PAC-01 (pale yellow powder, spray dried) : For drinking water treatment and wastewater treatment. Polyaluminum chloride - is one of the star products in the water treatment agent series. Polyaluminum chloride is a complex and efficient product with many advantages in one, such as ordinary polyaluminum chloride, spray polyaluminum chloride, and paper making special efficient polyaluminum chloride. All water treatment pharmaceutical products to the latest national standard as the inspection standard, water treatment pharmaceutical GB15892-2009 as the testing standard.

Water treatment agent - high efficiency polymeric aluminum chloride is the best inorganic polymer water treatment agent at present in China. The treatment effect of water of various concentrations is quite good, and the dosage is less. The dosage is 50% less than that of ferrous sulfate of the same concentration, and 10% less than that of polyaluminum chloride of the same concentration. High effect and low energy are mainly due to the high degree of polymerization of PAFC, because in the hydrolysis process of general iron salt and aluminum brine treatment agent, only AL(OH)2+, AL(OH)+2, Fe(OH)2+, Fe(OH)+2 and other simple hydrolyzed hydroxyl ions can be generated, while PAEC itself is AL3+, Fe3+ preaqueous medium. In addition to the above hydroxyl ions, it can mainly generate a large number of degrees of dissociation, positive charge dissociation: AL4(OH)4+8, Fe4(OH)4+8...... Such as polyhydroxyl cation, to neutralize the colloid particle charge in water and compress the double electric layer, at the same time hydroxyl bridging, crosslinking, surface adsorption and other reactions, in the corresponding collision, condensed into large alum flower, rapid precipitation.

Basic aluminum chloride is a new kind of inorganic polymer flocculant, which is a kind of high efficiency, fast and low consumption water treatment agent. In the water and the negative charge carried by colloidal particles instantaneous neutralization, so that the colloidal stability, colloidal particles quickly flocculated, and further bridge to generate flocculation and rapid precipitation. The turbidity removal effect is 1. 5 ~ 3 times that of aluminum sulfate according to the effective composition. The flocculation effect of low temperature turbidity-water and high turbidity water is incomparable to that of ordinary inorganic coagulants. Widely used in urban water supply treatment, water reuse treatment, urban sewage treatment, oilfield reinjection treatment, circulating cooling water treatment, industrial water supply treatment and papermaking, printing and dyeing, leather, ceramics, metallurgy, mining, oil, fluorine, coal washing and other industrial wastewater treatment. The effective dosage of the product is 20-50mg /L. Liquid products can be directly measured and added, solid products need to be prepared into 10% ~ 15% solution in the dissolution tank, and then measured and added according to the required concentration. Polyaluminum chloride can also be used in paper sizing, casting molding, medical refining, cosmetic manufacturing, catalyst carrier, sludge dewatering, cement quick setting, cloth wrinkle prevention, sugar liquid, glycerol refining and other aspects.
