Product Description


Polyethylenimine (PEI) is divided into linear and branched, linear polyethyleneimine contains all secondary amines, and branched polyethyleneimine contains primary, secondary and tertiary amines. . Linear polyethyleneimine of any molecular weight is solid at ordinary temperatures, while branched polyethyleneimine is a liquid. Linear PEI is soluble in hot water or low pH methanol, ethanol or chloroform, but insoluble in cold water, benzene, ether and acetone; one end of the polymer chain is methyl and the other end is amino; melting point is 73-75 ° C ; can be stored at room temperature.

use
Alkali zinc refiner; galvanized intermediate, a water soluble high molecular polymer. Colorless or light yellow viscous liquid, hygroscopic, soluble in water, ethanol, insoluble in benzene. Commercially available products are usually aqueous solutions having a concentration of 20% to 50%. The degree of polymerization used in the paper industry is about 100, the aqueous solution is positive, and the pH of the 5% aqueous solution is 8-11, which gels in the presence of acid. Polyethyleneimine has a high reactivity, can react with hydroxyl groups in cellulose and cross-link polymerization, so that the paper produces wet strength and has a dry reinforcing effect. The presence of any acid, base and aluminum sulfate will affect its wet strength and retention. It is mainly used as a wet strength agent for unsized absorbent paper (such as filter paper, blotting paper, toilet paper, etc.), but it is more difficult to handle paper. In addition, it can speed up the pulp water filtration, making the fine fibers in white water easy to flocculate. It has strong binding ability to acid dyes and can be used as a fixing agent for dyeing paper with acid dyes. It can also be used to process cellophane to reduce the wetting deformation of the paper. Polyethyleneimine can also be used for fiber modification, Printing And Dyeing Auxiliaries, ion exchange resins, and coagulation and sedimentation (metal capture, wastewater treatment).
