Biqing water free samples, technical support, Tracking service, your satisfaction, my pleasure ......... flocculant PAC main properties of poly aluminum chloride Pictures poly aluminum (Poly aluminum Chloride) code PAC chloride. Also commonly known as water purification agent or coagulant, it is between ALCL3 and AL (OH) 3 between a water-soluble inorganic polymers, chemical formula is [AL2 (OH) NCL6-NLm] where m represents the degree of polymerization, n represents a neutral level of PAC products. The product is compared with other coagulants, it has the following characteristics: a wide range of applications, adapt aqueous extensive. Easy to quickly form large alum, precipitation good performance. Suitable for a wide range of PH value (5-9 rooms), and the treated water after PH value and alkalinity decrease little. Water temperature is low, you can still maintain a stable sedimentation effect. Alkalized degree than other aluminum, iron high erosion of the smaller device. PAC physical and chemical properties of the product is an inorganic polymer coagulant. Mainly through compression bilayer adsorption charge neutralization, bridging adsorption, precipitation was netting mechanism of action, so that the water fine particulates and colloidal ion destabilization, aggregation, flocculation, coagulation, sedimentation, to purify the treatment effect. Spray drying type PAC, the appearance of a white or yellowish powder, the product of the reaction, spray molding process is made, a full set of computer-controlled equipment, product quality and stability. Product quality indicators: Al2O3≥30, basicity any standard in the 60 to 85 range. Water insolubles ≤0.1%, this technology products mainly for export, mainly used in domestic food additive of like goods, drinking water purification and other industries. Spray drying poly aluminum chloride is water soluble substance, has good thermal stability and high solubility in the drying process, the 40% -50% of poly aluminum chloride solution is introduced into a high pressure solids pump, pressurized through the atomizer into the spray dryer, dispersed into tiny droplets, droplet granular product was obtained after drying, the drying and granulation simultaneously.

That is per thousand tons of water dosage is 3-6kg specific dosage 100 ~ 500mg / time, the raw water high turbidity, the dosage appropriate to increase the turbidity is low, the dosage may be appropriate to reduce the water test performed according to water quality, and then select the best dosage put into use. PAC Type Product Name: spray drying poly aluminum chloride, aluminum chloride white, formula: [AL2 (OH) LnCL6-n] m technical standards: GB15892-2003 Product features spray-drying type PAC PAC features depends on the operating principle of the pressure sprays. Through the pressure produced by the spray drying process of porous granules of aluminum chloride or hollow small particles, dust and showing smoothness. Due to better contact with the water to be treated, its wettability and water velocity is stronger than other powder products. Spray drying PAC production is not only, but at the same time make it into tiny particles. PAC is a water soluble substance while exhibiting good thermal stability and solubility. The 40-50% aluminum chloride solution into the high-pressure pump, sprayer dried granular product is formed. Dehydration and the formation of particles at the same time in this production process. PAC use PAC is an inorganic polymer flocculant. After hydroxyl ion functional groups and polyvalent anionic polymerization functional groups, to produce with large molecular weight and high charge of inorganic polymer. PH value can be adapted to a range of 5.0-9.0, the best PH value of 6.5-7.6. 1 can be used in rivers, lakes and groundwater treatment 2. Can be used in industrial water and industrial water recycling waste water treatment 3. may be applied 4. Can be used in coal processing and porcelain flush wastewater recycling industrial wastewater. 5. Can be applied to printing, dyeing, tanneries, breweries, meat processing plants, pharmaceutical plants, paper mills, coal washing, metallurgy, mining, as well as fluorine, oil and heavy metals in waste water treatment. 6. can be applied wrinkle-free leather and fabric. 7.

The liquid product can be directly put in, it can be diluted after delivery. The solid product was dissolved after dilution needs to run. According to water quality and quantity of products to be processed to determine the dilution water. Dilution ratio of 2 to 20% solid product, liquid product (based on weight) 5-50%. 2. put the amount of liquid product is 3-40 g / t, solid state put the amount of 1-15 g / ton, the specific amount invested in the flocculation tests and experiments shall prevail. 3. Spray drying type PAC acidity than other inorganic flocculants. The difference between the production process and ordinary spray-drying PAC PAC production process: spray drying: liquid feed pressure filter ---- ---- ---- finished spray tower spray drying ordinary dried: liquid feed Place ---- ---- ---- finished drying drum
