White spray drying PAC is composed of aluminum hydroxide powder and high purity hydrochloric acid by spray drying processing of a white or milky white powder-like fine powder melts easily exposed in the air, color purity, the product of the water After the solution is clear and transparent, without any color, while the ordinary aqueous poly aluminum color yellow or brown. [Technical Standards] product quality in line with national standards [Appearance] White, milky white powder-like fine powder spray drying PAC uses: 1, white spray drying PAC is mainly used for drinking water, industrial water supply , oil field injection water, cooling water and a variety of water (such as municipal sewage, oily wastewater, wastewater dyeing, papermaking wastewater, sewage bleaching mills, etc.) processing. 2, paper sizing precipitating agent, clarifying sugar bleaching agent. 3, for a number of areas tanning, pharmaceutical, cosmetics and precision casting. Features a white PAC) with a large positive charge, form stability polynuclear hydroxy aluminum complexes, can effectively promote flocculation, sizing. 2) the appearance of white, low iron content, to meet the needs of manufacturing high-quality paper. 3) is a pre-hydrolyzate PAC aluminum chloride, a relatively low degree of hydrolysis, the pH of the pulp to decrease smaller than that of aluminum sulfate. 4) is only suitable for acidic aluminum sulfate sizing, and PAC can in acidic and neutral sizing environment, corrosion of the system significantly weakened, Whitewater handling easier. 5) may be filled inexpensive calcium carbonate filler, not only reduce production costs and improve the whiteness of the paper and folding resistance, but also to overcome the synthetic material (such as AKD, etc.) is difficult to avoid the disadvantage (such as slipping, sizing of difficult to control). 6) Use PAC sizing, slurry retention, drainage function improved significantly. 7) In addition to breaking length of paper performance, other indicators have improved to varying degrees. The use of PAC white solid product is formulated as a 10% liquid content of the product, add 1.5-3.0% of the liquid product to be sizing slurry, and stirred sufficiently to be mixed with the slurry. Like its usage with aluminum sulfate, aluminum sulfate dosage is only one-third, according to absolutely dry paper calculated the amount of 2% to 3%. White PAC and protective packaging products inside and outside the double packaging, plastic bags, topical bags. 25 kg per package. White PAC Note: 1, the product is acidic products, with the absolute prohibition of 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 place for storage. 3, in the bags in good condition, shelf life of one year.
