LeBron [Shiyan SS Suizhou] mills polyacrylamide dissolution methods

LeBron [Shiyan / Suizhou] mills dissolution method polyacrylamide. Often used in paper mills polyacrylamide products. Wastewater will use conventional cationic polyacrylamide. Rather than ions are generally used to process the paper pulp during the retention and drainage effect. Today, music for everyone 邦范 children popularize technical paper mill machine with dissolved polyacrylamide. We all know that not one hundred percent polyacrylamide completely dissolved in the time of dissolution, there will be a small part of the group is not completely dissolve the gel, so the application must be added filtration equipment, to prevent these groups into the gel mill machine hanging nets and sticky paper felts or produce disease. At the beginning of the string machine water, first joined polyacrylamide, allowing the system to prevent the presence of polyacrylamide long fibers dispersed without clumping, making production more quickly reach the normal state. Because disposable polyacrylamide not adding too much, it is necessary to make it uniform, uniform, and dispersed added. And adding the speed can not be too fast, usually in the 0.15 kg / min or so. Polyacrylamide added to the water at the same time, there should be some added pressure water injection point, so that in addition to water immediately after dilution and dissolution, to achieve the best effect dissolution. Polyacrylamide Although soluble in water, but because when it reaches 10% or more the dissolved concentration, in water to form a clear gel will lose flowability. If during dissolution instant lot of polyacrylamide added, in a region in the water will dissolve to a concentration of greater than ten percent of the system 10, the process is difficult to continue to dissolve. So must be a certain amount of water, not seen until after the mixing blades, agitator, and then adding an aqueous solution of polyacrylamide cycle requires mixing blade should not have corners, edges, or will cause hanging material and cut poly adverse effects of acrylamide molecular chain, dissolved concentration allowed, and weakened its dispersion. Cationic polyacrylamide high concentration of dissolved easily, usually around 0.5 thousandths 5-1. Polyacrylamide time not too long stir to dissolve, stirring time is generally 60-80 minutes or so, otherwise it will destroy its dispersion. Polyacrylamide should now use now dissolved, because water will automatically hydrolyzed polyacrylamide within 20-48 hours, lose stickiness, and ultimately lose dispersion. When polyacrylamide added level changes on the paper machine pulp dewatering rate will change. Polyacrylamide dosage adjustment is too large, there will be too fast or too slow dehydration, affecting the production of normal and stable. Therefore, when normal production machine, do not arbitrarily adjust the amount is too large polyacrylamide. Applied to the long fiber dispersant polyacrylamide should use ion type anionic or nonionic. LeBron polyacrylamide manufacturers of the various processes and paper mills have a deep grasp, can provide various models, different molecular weight cationic, anionic and nonionic polymer flocculant for all aspects of the paper, the treatment effect is very satisfactory. www.lebangshui.com www.lb021.com incense powder flocculant PAC www.lb0371.com
