Nonionic polyacrylamide is the white powder with the molecular weight from 5,000,000 to 12 000 000. The CPAM with the icon degree from 20% to 80% has good water solubility, and it can be dissolved in the water by the arbitrary proportion but not the organic solvent. Besides,it has the characteristics of high-polymer electrolyte,and it can be applied inthe treatment of waste waterrich in organics with negative charge.
Use
(1) Sludge dewatering.
(2) Domestic and organic water treatment: It is positive in charge in the acid, neutral and alkaline medium.
(3) The intensifier in the paper making industry.
(4) It can be used as the additive chemicals in the oil field.
Non-ionic polyacrylamide is formed by the homopolymerization of acrylamide. It has high purity ,good fuction,wide uses, and its main usages are as follows:
1) It is the raw mateials used for the changed pam, for example, anionic pam .we can get them from the hydrolysis by choosing different types of nonionic pam.
2)Textile industry auxiliary .It can be made into slurry chemicals by adding other additives. For textile sizing, can improve the adhesion, penetration and performance of pulp removal, the fabric has anti-static, reduce sizing rate, plasma cutter to reduce plaque, cloth breakage rate and litter.
3) Agent for the wastewater treatment.
4) Agent for the desert treatment
5) Good way for soil improvement in the dry area.
6) Agent for oil field plugging
7) Can be use in architecture, and paint for interior wall.
