Many customers or purchasers do not know about polyacrylamide products when they buy them. In addition to asking the price, there will be many questions. For example, the product specification, type, index, etc., among which the most question is whether polyacrylamide belongs to the dangerous chemicals?
First of all, is it harmful to human body? I hope I can help you by explaining these questions. Polyacrylamide product appearance is white powder, soluble in water, almost insoluble in benzene, ether, ester, acetone and other general organic solvents, its aqueous solution is almost transparent thick liquid, non-hazardous, non-toxic, non-corrosive. After entering the human body, polyacrylamide is mostly eliminated from the body in a short time, rarely absorbed by the digestive tract, so it is not toxic. Most commodities also do not irritate the skin, with only some water disintegrating likely to have residual alkali, which can irritate when exposed repeatedly and over a long period of time.
The U.S. food and drug administration considers PAM and its water breakup to be low toxicity or nontoxic. The toxicity of PAM comes from the residual acrylamide monomer and toxic metal during production. Acrylamide is a kind of neurotoxic agent that can damage the nervous system. Therefore, the health departments of all countries have stipulated the content of acrylamide remaining in industrial products of polyacrylamide, generally 0.5-0.05%. The content of acrylamide should be less than 0.2% when applied to the general purification treatment of water, and less than 0.05% for direct drinking water treatment. Currently, it is generally stipulated in major European and American countries that the residual acrylamide content in drinking water treatment and food is less than 0.05%, and the amount of PAM is strictly controlled. For flocculation of drinking water treatment, food grade products should be used as appropriate. Select food grade quality, low residual value of polyacrylamide products, can ensure the health and safety of drinking water.
Polyacrylamide in the use of water treatment process, the advantage of its strengthening flocculation and filtration processability, improving water quality, increase water quantity, cost savings are accepted by more and more water supply enterprises. Polyacrylamide applied in the field of drinking water treatment is being developed constantly, its prospects are very positive. So polyacrylamide is not belonged to the dangerous chemicals. Transportation is unregulated.
