Biqing offer free samples, technical support, Tracking service, your satisfaction, my pleasure ......... PAC physical and chemical indicators of the product is an inorganic polymer coagulant. Mainly through the double compression, adsorption charge neutralization, bridging adsorption, precipitation substrates netting mechanism, so that the water fine suspended particles and colloidal ion destabilization, aggregation, flocculation, coagulation, sedimentation, to purify the treatment effect. Spray drying PAC, the appearance of a white or yellowish powder, the product of the reaction, spray molding process made all the equipment by computer-controlled, stable product quality. Product quality indicators: Al2O3≥30, basicity any standard in the 60 to 85 range. Water insoluble ≤0.1%, this technology products mainly for export, mainly used in domestic like products of food additives, water purification and other industries. Spray drying poly aluminum chloride is a water-soluble substance, has good thermal stability and high solubility in the drying process, the 40% -50% of poly aluminum chloride solution containing solids introduced high-pressure pump, After pressing into the dryer through the atomizer atomized, dispersed into tiny droplets, droplet granular product was obtained after drying, so that drying and granulation simultaneously.

PAC Type Product Name: spray drying poly aluminum chloride, aluminum chloride white, molecular formula: [AL2 (OH) LnCL6-n] m technology standard: GB15892-2003 Features spray drying PAC PAC Depending on the operating characteristics of the principle of pressure spray. After pressure spray drying process produced a porous aluminum chloride for small particles or hollow small particles, showing dust and smoothness. Due to better contact with the water to be treated, and its wettability and water speed are stronger than other powder products. Spray drying is not only the production of PAC, but at the same time make it into tiny particles. PAC is a water soluble substance while exhibiting good thermal stability and solubility. 40-50% of the aluminum chloride solution into a high pressure pump, sprayer dried granular product is formed. Dehydration and formation of particles simultaneously in this production process.
