An overview of nonionic polyacrylamide products

[Sunny Zhao]

Nonionic polyacrylamide is water-soluble polymer or polyelectrolyte. Due to its molecular chain contains a certain number of polar groups, it can through the adsorption of solid particles suspended in water, make the bridge between particles or by charge neutralization condensed to form large floc particles. So, it can accelerate the particles in the slurry settlement, there is a very significant to speed up the solution to clarify, promote such as filtering effect. Mainly used for all kinds of industrial waste water flocculation sink down, precipitation clarification process. Such as paper and pulp waste water treatment, wastewater processing and metal smelting process of wastewater treatment, steel and stone processing plant waste water treatment, etc.

The major raw materials for the production of the handmade paper and the other paper products is the actinidia chinensis and the abelmoschus manihot. The paper making pulp is mainly from the abelmoschus manihot root liquid, the carambola cane juice, the holly leaf juice, the machilus pauhoi joice and the waxy leaf juice etc.

The new type of the paper making dispersant uses the anionic polyacrylamide product with the 2,000 x 104 molecular weight, the viscosity of its aqueous solution is very high. As a new dispersing agent for the plant fiber, the new type anionic polyacrylamide dispersing agent can make the remarkable effect for the long fiber thin paper product in the fourdrinier paper machine or in the garden net paper machine, with the dosage of 01.% ~ 0.2% (for oven dry pulp) of this new type of dispersing agent of anionic polyacrylamide.
