Polyacrylamide is a general term for acrylamide homopolymer or polymer copolymerized with other monomers, and is one of the most widely used water-soluble polymers. It is a hard glassy solid at room temperature, and its products include glue, latex and white powder, translucent beads and flakes. With the gradual development of the current society, polyacrylamide is more and more widely used in various fields, so what are its applications in the printing and dyeing industry?
1. In the textile industry, polyacrylamide flocculants are used as sizing agents and finishing agents for fabric post-treatment, which can form a soft, anti-wrinkle and anti-mildew protective layer.
2. When used as printing and dyeing auxiliaries, it can make the product have high adhesion fastness and brightness, and can also be used as a non-silicon polymer stabilizer for bleaching.
3. Polyacrylamide as a post-treatment agent can prevent static electricity and flame retardancy of the fabric.
In summary, polyacrylamide can be used as sizing agent, finishing agent, printing and dyeing auxiliary and treating agent in the printing and dyeing textile industry, and has a good purification effect in the wastewater discharge. It can not only be used in printing and dyeing industry, but also widely used in oil exploration, water treatment, textile, paper making, mineral processing, medicine, agriculture and other industries.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
