Polymerization aluminum sulfate is a white or grayish yellow block or sheet object, mainly used for drinking water purification and industrial wastewater treatment flocculant; paper can also be used to increase the paper's strength additives, coloring agents, and defoamers Wait.
First, the performance; polymerization aluminum sulfate as a white granular powder, soluble in water, insoluble in alcohol, acidic aqueous solution, the preparation concentration can not be too low, typically 5-10%, when used as a water treatment agent, preparation of a good solution can not Long-term storage, in order to avoid hydrolysis, reduce coagulation effect.
Second, use: polymerization aluminum sulfate is mainly used for drinking water, industrial water and waste water purification treatment, especially for low-temperature, low turbidity PH value high water has a significant effect, you can also remove the water color, algae and other additional. It is also a good fluoride removal agent, also widely used in papermaking, oil clarifying agent, concrete waterproofing agent.
Third, Storage: polymerization aluminum sulfate with inner coating of polyethylene or polyethylene bag lined woven bag, net weight 25kg stored in dry and ventilated warehouse, prevent pollution and toxic substances in the moisture transport should be.
