Polyacrylamide is a polymer compound formed by acrylamide and a certain monomer material together. The main ingredient is acrylamide. The quality of acrylamide directly affects the effect and quality of synthetic polyacrylamide. At present, there are two main industrial productions of acrylamide.

First: Chemical Law

It uses acrylonitrile as raw material, adopts framework copper as catalyst system, and uses direct hydration to produce acrylamide. It is the second generation synthesis technology of acrylamide production. The acrylamide produced by this technology has a high acrylonitrile conversion rate, good quality polyacrylamide products, no by-products, low energy consumption, low waste water, waste gas, and waste discharge.

Second: Biochemical Law

Using biological enzymes as catalysts, mixing acrylonitrile, water and biological catalysts into a hydration solution, and separating the catalyst after the catalytic reaction to obtain acrylamide products. Compared with the chemical method, the conversion rate of acrylonitrile is higher, basically reaching 100%, no side reactions, no ion exchange, simpler separation and refining operation, no need for thickening operation, simpler operation process, less equipment investment, and high production efficiency , It is especially suitable for producing high-viscosity and ultra-high molecular weight polyacrylamide.
