WHITE POLYALUMINAL ALUMINUM WHICH ARE WHAT IS FOR WHITE POLYALUMINAL CHLORIDE? WHITE POLYALUMINAL ALUMINUM WHICH ARE WHAT IS FOR WHITE POLYALUMINAL CHLORIDE? White polyaluminum chloride is a kind of white or milky milk powder fine powder made of aluminum hydroxide powder and high-purity hydrochloric acid spray-dried, it will melt in the air. In recent years, white polyaluminum chloride has replaced aluminum sulfate as a neutral sizing agent in the paper industry. Compared with aluminum sulfate, white polyaluminum chloride has the following characteristics: a large number of polynuclear hydroxyls with positive charges and stable morphology Aluminum complex, can effectively promote flocculation, sizing. The appearance of white, very low iron content, to meet the needs of manufacturing high-quality paper. Polyaluminum chloride is a prehydrolyzate of aluminum chloride, the degree of hydrolysis is relatively low, the decline in pulp pH value is smaller than aluminum sulfate. Aluminum sulphate is only suitable for sour sizing, whereas polyaluminum chloride sizing in acidic and neutral environments significantly reduces system corrosion and white water handling is easier. Can be filled with cheap calcium carbonate filler, not only reduces production costs and improve paper whiteness and folding resistance, but also overcome the synthetic rubber (such as AKD, etc.) are difficult to avoid the shortcomings (such as slipping, sizing difficult Control, etc.). Using polyaluminium chloride sizing, slurry retention, filter aid significantly improved. In addition to the performance of the paper rupture length, the other indicators are improved to varying degrees. White polyaluminum chloride is mainly used for domestic drinking water, industrial water supply, oilfield injection water, circulating cooling water and various sewage (such as urban domestic sewage, oily wastewater, printing and dyeing wastewater, papermaking wastewater, decolorization of steel mill wastewater). Paper sizing precipitator, sugar decolorization clarifying agent. Also used in tanning, medicine, cosmetics and precision casting and other fields.
