How is liquid polyaluminum chloride produced? Aluminum chloride production process Detailed: Poly aluminum chloride
products are divided into two kinds of solid and liquid, then we all know that liquid aluminum chloride production process? If you do not know, please read the following: Liquid aluminum polychloride poly aluminum and water by volume ratio of 1: 3 ~ 5 were mixed and stirred evenly, soaked for 5 to 8 hours; pump to the reactor, press The volume ratio of aluminum gray: hydrochloric acid: water is 1: 2.5 ~ 3.0: 3.0 ~ 4.0 by adding hydrochloric acid and water, set the temperature of 85 ~ 100 ℃, the reaction 2 ~ 3 hours; Add modifier to adjust the liquid aluminum oxide content and the basicity, such as the use of quicklime, liquid: quick lime dosage volume ratio of 1: 0.054 ~ 0.086, if the use of aluminum scrap, the dosing ratio of 1: 0.023 ~ 0.04, Calcium, dosing ratio of 1: 0.042 ~ 0.063; the temperature is controlled at 50 ~ 60 ℃, standing aging 48 to 72 hours to obtain a liquid polyaluminum chloride finished product.
Depends on your last indicator requirements, mainly from the role of accelerated precipitation of floc, iron content of about 1%, in general, when dealing with
White polyaluminum chloride has been replaced by aluminum sulphate as a neutral sizing agent in the paper industry
High profits But now the investment is a bit late Now too many manufacturers to produce the product Almost all of the customers are owned by the old manufacture
Chemical phosphorus removal usually does not exist alone, usually in the biological phosphorus removal on the basis of chemical-assisted dephosphorization, phos
This is not a fixed ratio, because the water turbidity different polyaluminum chloride dosage is also different, the specific best dosage can only be determined
