Mf: [al2(oh)ncl6-n•xh2o]m
hs: 3824909990
cas: 1327-41-9
standard: gb15892-2003
properties: dark brown .
Feasures: the product has a strong adsorption properties. In the hydrolysis process, some chemical physics process such as coagulation, adsorption and precipitation. The fundamental difference between pac and traditional inorganic coagulants is that traditional inorganic coagulants is low molecular crystal salt, while pac is consist of multiple carboxyl complex which with variety forms. With high speed of flocculent precipitate, pac can be used in various ph value. Non-corrosive pipeline equipment, water purification effect, can effectively remove ss, cod, bob, and heavy metal ion such as arsenic, mercury etc. In the water.
Usages: the product is widely used for industrial water and wastewater treatment, such as those containing radioactive substances, lead (pb + +) chromium (cr + + +) highly toxic heavy metals and fluoride (f) sewage. In addition, also use in precision casting, paper, leather, etc.
