Nonionic Polyacrylamide Water - Soluble Polymer
Sep 30, 2017

Polyacrylamide is a kind of important water-soluble polymer,Nonionic Polyacrylamide  has a special physical and chemical properties, widely used in various sectors of the national economy, according to the different production processes, polyacrylamide is divided into cationic, anionic, nonionic polyacrylamide The In many cases, Nonionic Polyacrylamide some dealers to provide customers with polyacrylamide treatment of sewage, the dealer in order to protect their own interests are not infringed, and not to inform the use of pharmaceutical ions and their molecular weight, in this case, how should we Is it possible to detect the ionic form of polyacrylamide water purifier?

The simplest way is to test the pH of the polyacrylamide solution,Nonionic Polyacrylamide and the pH of the various types of polyacrylamide solution is different. However, different manufacturers of polyacrylamide products and production process raw materials corresponding to the PH value is not all absolute. This method is only the most routine detection.

The products of anionic polyacrylamide and cationic polyacrylamide were selected and dissolved, and the polyacrylamide product solution to be tested was mixed with the two PAM solutions respectively. If the reaction was made with the anionic polyacrylamide product, Nonionic Polyacrylamide Acrylamide is cationic and reacts with cations to demonstrate that the PAM product is anionic or nonionic.

The high molecular weight CPAM can be obtained by the modified method. However, the high viscosity of the aqueous solution of high molecular weight nonionic polyacrylamide is difficult to be mixed and must be diluted, and the effective content of the modified product is very low (generally <5% ), Nonionic Polyacrylamide And the stability of the modified product is poor, the validity period is short, some modified products are higher prices.

Conventional copolymerization methods include aqueous solution polymerization, emulsion polymerization (conventional emulsion polymerization, inverse emulsion polymerization, Nonionic Polyacrylamide reverse microemulsion polymerization) and precipitation polymerization, photoinitiation polymerization.

The copolymerization method uses less equipment, the production process is simple, easy to obtain different molecular weight, but not easy to obtain higher molecular weight. Nonionic Polyacrylamide The molecular weight of the CPAM prepared by the copolymerization method is generally not as good as that obtained by the modification method, but the stability is good and the performance is good. The processing is easy and the price is acceptable.

There are many influencing factors of cationic aqueous solution polymerization, Nonionic Polyacrylamide and not only the temperature, Nonionic Polyacrylamide time and pH value have important influence on it. The polymerization additive also has a very important effect on its performance.
