Mud Viscosifier Chemical Nonionic Polyacrylamide
Property:
In the production of PAM, the main role of the initiator is to act as a redox reaction. The amount of initiator and the addition speed also affect the production of low molecular weight products. If the amount of initiator is small, the polymerization reaction cannot be initiated. If the amount of initiator is large, the reaction speed is accelerated, the polymer molecular chain is not easy to grow, the average degree of polymerization decreases, and the molecular weight decreases. The addition speed and method of the initiator affect the molecular size of the polymer. A lot of practice has proved that the molecular weight of the polymer increases with the increase of the time of addition. On the contrary, the molecular weight of the polymer will decrease. Therefore, in the production of low-molecular-weight products, strictly controlling the amount and speed of addition of hair initiators is a very critical part. The reaction temperature also directly affects the size of the molecular weight. If the temperature is too high, the polymerization reaction will intensify and the formation of implosion will seriously affect the size of the molecule and the solubility of the product. On the contrary, if the temperature is too low, the polymerization reaction will not proceed completely, and it will also affect the molecular weight. size. Therefore, in production, this is as important as the use of initiators, requiring uniform requirements and strict control.
The industrial production of polyacrylamide also has a history of decades, and the production process has been continuously improved. Now, in terms of molecular weight, PAM products mainly have three types: high, medium and low, with adjustable degrees between 104-107. Among them, low-molecular-weight products have higher requirements for each link in the production process. The production of low-molecular-weight PAM requires relatively high purity of raw materials. General industrial monomers contain iron, copper, 02 and other impurities. These impurities will hinder the progress of the reaction. Therefore, when making acrylamide monomers, the content must be controlled at above 95.

Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation, can reduce the friction resistance between liquids, and can be divided into non-ionic, anionic, cationic and There are four types of amphoteric type, so anionic polyacrylamide is a water-soluble polymer with negative charge groups.
