Detailed Product Description: | Polyacrylamide is an organic polymer flocculant, relatively large molecular weight, generally in one million, ten million, will be dissolved when the swell and then slowly dissolve, if the use of artificial dosing way, one into the water polyacrylamide dosing volume, and also not uniform, then added slowly, polyacrylamides part of the first contact with water, they begin to swell, and the surface area becomes large, then wrap the part not in contact with water (can floc remove peel look, the middle is dry, not wet), so that can not be dissolved to form a polyacrylamide group. Most sewage treatment plants are generally used artificial dosing (if the switch to automatic feeder dosing, it not only saves manpower, and can maximum efforts to avoid this situation). Recommended dosing when the first water, stir up, and then out of the water column above the inlet uniform dosage slowly to allow agents along the water into the water, thus reducing the probability of knot groups, in addition to adding as much as possible in Avoid contact with the Pharmacy and dissolution tank wall. Recommendation: as far as possible under conditions permitting the use of automatic continuous feed systems, improve work efficiency and also can be a good time to avoid dosing agglomerate situation. Also currently on the market polyacrylamide uneven quality, some products inherent quality defects, products hydrophilic bad insolubles are more poor solubility in the dosing easy when agglomerate. In contact with newly recruited distributors, as well as friends and chat up the company's products, the most asked question is polyacrylamide poisonous do, on this issue and we explore here, and I hope new to this product useful friends. Ado, straight into the subject: a data online excerpt: U.S. Food and Drug Administration says, PAM and water disintegration is low or no toxicity. PAM residual toxicity of acrylamide monomer from the production process and entrained toxic metals. Acrylamide is caused by nerve agents, there is damage to the nervous system, poisoning of the body after the table weakness, ataxia and other symptoms. Therefore, provisions of national health departments have industrial products polyacrylamide residual acrylamide content, typically 0.5% --- 0.05%. The general process used in water purification, the acrylamide content of 0.2% or less, for direct drinking water treatment, the need to 0.05%. International Health WHO 1985 criteria noted polyacrylamide born: PAM control the amount of residual AM and control the amount of 0.05% or less, the content of the treated water will be less than 0.25ug / L, in line with most national standards for drinking water . General provisions of the current major countries in Europe and America, drinking water treatment and food residue AM PAM content below 0.05%, and controls the amount of PAM. Some cationic polyacrylamide situation is much more complicated, because the introduction of cationic polyacrylamide amino group etc., and its toxicity is often tens to hundreds of times higher than the anionic and non-ionic, they Chronic toxicity is further studied.
