Polyacrylamide rich students polyacrylamide manufacturers Which is good

Amphoteric polyacrylamide Product Overview zwitterionic polyacrylamide cationic monomer copolymer, acrylamide monomer, triple from hydrolyzing agent. The product is the molecular chains of both positive charge, negative charge there zwitterion irregular polymers. Product appearance of white fine particles or powder. Category and performance indicators molecular weight (million) Solid content% effective anionic Cationic PH value of residual monomer% Exterior ≥800 90 1-14 10 15 ≤0.05 white particles ≥1000 90 1-14 25 30 ≤0.05 white particles ≥1200 90 1-14 55 10 ≤0.05 white particles with polyacrylamide dyeing method: dosing concentration polyacrylamide more dilute solution, the better, the more dilute the concentration of dosing solution enables the rapid expansion in the water, fully mixing and prevent excessive concentration of protective colloidal phenomena affect and effect. But the concentration is too thin can cause huge dosing device. General dosing concentration in thousandths of concentration appropriate. Currently, the leather dyeing wastewater treatment or physicochemical method based, but not ideal. Although dyeing wastewater treatment methods Some methods for leather dyeing wastewater, but compared with the biological chemical method were running high cost, therefore, from a business point of view, research and development of a compact, fast processing speed and stable operation of new high anaerobic reactor, is the most cost-effective leather dyeing wastewater treatment. l, when used, dubbed 0.1 a 0.2% aqueous solution concentration to use neutral salts debris-free water is appropriate. 1, when used, dubbed 0.1 a 0.2% aqueous solution concentration to use neutral salts debris-free water is appropriate. 2, when dissolved, the cationic polyacrylamide products even thrown into stirred water, stir speed control in 100,300rPm. Appropriate heating ((60 ℃), can accelerate the dissolution. 3. Adjust liquid to be treated PII value, so that the product fully functional (the amount of PII by selecting the best value and the test of this series.) 4, adding a cationic When polyacrylamide product solution, should speed mixed with liquid to be treated, there floc, the stirring speed to slow down in order to facilitate and accelerate the growth of floc settlement.
