Polyacrylamide Decentralized Effect
Nov 01, 2017

Mention the textile, we are no stranger is also inseparable from the open And mention polyacrylamide in the textile industry, what role, I think a lot of people do not know. Textile industry in the domestic enterprises is also very much, according to the National Bureau of Statistics data: as of the end of 2013, China's textile industry above the scale of the number of enterprises reached 20776, how a huge number of ah. Now is 2017 years, Polyacrylamide since the three years, the environmental pollution is also very serious. As a new century enterprises, the development of green products without delay. In the textile industry, Polyacrylamide green textiles represent environmental protection and health. Polyacrylamide as an indispensable industrial additives in the environmental protection industry, in the textile industry is also playing a very wide range of roles.

Polyacrylamide is soluble in water, but because of its dissolved concentration of more than 10 percent, will form a transparent gel in water and loss of mobility. Polyacrylamide If a large amount of polyacrylamide is added instantaneously during the dissolution process, a dissolution system with a concentration greater than 10% is formed in a region of the water, making it difficult to continue the dissolution process. So must first add a certain amount of water, until the mixing leaves did not, start the mixer, Polyacrylamide so that the water cycle after adding polyacrylamide, stirring the blade should not have edges and corners, knife edge, otherwise there will be hanging material and shear poly Acrylamide molecular chain of adverse effects, Polyacrylamide so that the dissolution concentration is not allowed, and weaken its dispersion. Cationic polyacrylamide dissolved concentration is not too high, generally about 0.5-1 in the distance. Polyacrylamide stirring dissolving time is not easy too long, the general mixing time in 60-80 minutes or so is appropriate, Polyacrylamide otherwise it will destroy its dispersion effect.

Polyacrylamide should now be dissolved, because polyacrylamide aqueous solution in 20 to 48 hours of automatic hydrolysis, loss of viscosity, and ultimately loss of dispersion.

When the amount of polyacrylamide increases, the rate of dewatering of the slurry on the machine will vary. Polyacrylamide dosage adjustment is too large, Polyacrylamide there will be too fast or too slow dehydration, affecting the production of normal and stable. Therefore, in the normal production of paper machine, do not arbitrarily adjust the amount of polyacrylamide. Polyacrylamides for use in long fiber dispersants should be of anionic or nonionic type.
