Polyacrylamide manufacturers to large-scale and high efficiency into the competition more and more intense competition

- Oct 27, 2017 -

 

Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation, can reduce the friction between the liquid resistance.

  With China's polyacrylamide (PAM) industry demand for the operation of the market continues to expand and export growth, China's polyacrylamide (PAM) industry operation usher in a new development opportunities.

The properties of polyacrylamide PAM aqueous solutions often exhibit instability. Unstable physical phenomena are diverse, and their causes are different, there are two main categories, namely, various factors caused by the degradation of polyacrylamide aqueous solution and polyacrylamide molecular chain structure changes. The consequence of the degradation is that the molecular chain breaks and the molecular weight decreases, resulting in a decrease in the viscosity of the polyacrylamide aqueous solution. Specific reasons for the following aspects:

The effect of molecular structure: polyacrylamide aqueous solution in the form of various forms of hydrogen bonds and the formation and rupture of the structure affect the stability of the solution.

    Effect of product purity: Oxidizing impurities such as residual initiators in the product can degrade, but have little effect because high purity polyacrylamide products are also unstable.

    Environmental factors: environmental temperature, light, atmospheric oxygen, carbon dioxide and other environmental factors on the degradation of polyacrylamide aqueous solution will have a certain impact.

    Microbial degradation: Unclean polyacrylamide aqueous solution there is a large instability, the water micro-organisms can promote the degradation of the product play a role.

 The impact of relative molecular mass: the higher the molecular weight of the polyacrylamide products show some of the more unstable. Polyacrylamide aqueous solution degradation is currently irresistible, and finally polyacrylamide manufacturers to remind you that the use of polyacrylamide must be with the use, with with with.

     Bo source of water purification materials manufacturers after years of rapid development, economic and technological strength continue to increase, continue to expand the scale of business, business categories continue to complete, in technology and market with each other to support.
