Polyacrylamide PAM products are water-soluble polymers. According to their functional groups, they can be divided into four types: non-ionic, anionic, cationic and amphiphilic. Application scope of polyacrylamide PAM products: 1. mainly used as flocculant: widely used in the treatment of chemical industrial waste water, waste liquid, municipal sewage treatment, water industry, purification and clarification of high turbidity water, coal washing wastewater, mineral processing wastewater, metallurgical waste water, iron and steel wastewater, zinc, aluminum processing wastewater and electronic industrial waste. Water and other treatment. 2. for paper industry, one is to improve the retention of filler and pigment, to reduce the loss of raw materials and to the pollution of the environment; two to improve the strength of paper (including dry strength and wet strength). In addition, the use of polyacrylamide also improves the avulsion and porosity of paper to improve the visual and printing properties and also to use In food and tea packaging paper. 3. it has been widely used in petroleum industry, oil extraction, drilling mud, waste mud treatment, water channeling prevention, friction reduction, enhanced oil recovery, and three oil recovery. 4. for textile sizing agent, slurry performance is stable, less pulp, fabric breakage rate is low, cloth clean. 5. polyacrylamide products are also widely used in thickening, stabilizing colloids, drag reduction, bonding, film forming, biomedical materials and so on. 6. other industries. In the food industry, it is used for sugar cane sugar, sugar cane juice clarification and syrup extraction; enzyme preparation fermentation liquid flocculation and clarification industry; synthetic resin coating; soil building grouting material water plugging; building materials industry, improving cement quality, construction adhesives, filling repair and water plugging agent; soil improvement, water conservation; electroplating industry; printing and dyeing industry Industry and so on. The use of polyacrylamide PAM products and points for attention: 1., through a small test, determine the best model, and the good dosage of the product. 2. the product is made up of water solution of 0.05%-0.4% concentration, and the solvent is neutral salt free. 3. when dissolved, evenly spread the product into the stirring water. Proper Garwin (<60 C) and stirring can speed up the solution. 4. solid products should be avoided on the ground so as to prevent the products from becoming slippery after absorbing moisture. 5. when preparing polyacrylamide aqueous solution, it should be carried out in enamel, galvanized, aluminum or plastic pail, and can not be prepared and stored in iron container. 6. polyacrylamide aqueous solution should be ready for use now. When the solution is placed for a long time, its performance will gradually decrease with time.
