3. Application
PAC is a kind of inorganic macromolecule flocculant. through the hydroxyl ion bridging function and the polyvalent anion polymeric function, it produces large molecular and high electricity inorganic macromolecule. It adapts a wide PH range of 5.0~9.0, and the best is between 6.5~7.6.
1) Purification of river water, lake water and underground water, industry water and industry recycling water.
2) Reclaiming coal from coal-washing waste water and kaolin in ceramic industry
3) Purification of the waste water in printing and dyeing industry, leather industry, brewage industry, meat-processing industry, coal-washing, metallurgy industry, mine, pharmacy, paper-making, and purification of the waste water containing fluorine, oil and heavy metals
4) Tannage and cloth cockling-prevent, Catalyzer carrier.
5) Cement Solidifying, and moulding; Refining of pharmaceuticals, glycerine and sugar; Paper-making glue.

聚合氯化铝（PAC）
[中文名称]：聚合氯化铝（PAC）又称碱式氯化铝(basic aluminium chloride)
[英文名称]：aluminium polychloride，缩写为PAC
CAS No.: 1327-41-9
[分子式]：[Al2(OH)nCl6-n·xH2O]m(m≤10，n=1～5)
[技术标准]：产品质量符合国家标准GB15892-2003
[主要特点]：应用范围广，适应水性广泛。易快速形成大的矾花，沉淀性能好。适宜的PH值范围较宽（5－9）且处理后水的PH值和碱度下降小。水温低时，仍可保持稳定的沉淀效果。碱化度比其它铝盐、铁盐高，对设备侵蚀作用小。
[用途]聚合氯化铝是一种无机高分子絮凝剂。经过氢氧基离子官能团和多价阴离子聚合官能团的作用，产生出拥有大分子量和高电荷的无机高分子。可适应PH值范围为5.0-9.0，最佳PH值为6.5-7.6.
1. 可应用于河水、湖水及地下水的处理，工业用水和工业循环用水的处理。
2. 可应用于煤矿冲刷废水和瓷器工业废水的回收。
3. 可应用于印刷厂、印染厂、皮革厂、酿造厂、肉类加工厂、制药厂、造纸厂、洗煤、冶金、矿区，以及对含氟、油、重金属的废水的处理。
4. 可应用于皮革和布料的防皱。可作为良好的触媒。
5. 可应用于水泥凝固和模制浇铸；医药品、甘油和糖类的精炼；造纸的粘合。
