Use of product

The unique decolorization ability is mainly used in the decolorization treatment of high chroma wastewater of dye factory. The applicable dyes are active, acid and disperse dyes and other wastewater treatment; Can also be used for textile, printing and dyeing, ink and other industrial wastewater treatment; This product can also be used as a reinforcing agent for paper making, sizing agent, etc

This product has been widely used as polymer flocculant in tap water and sewage treatment. Especially for the high turbidity of raw water in flood season, in order to make the clay, silica, microorganisms and hydrated metal oxide in raw water can be effectively coagulated, usually choose this product treatment

Flocculant, dehydration coagulant

application

Polydimethyl diallyl ammonium chloride is a linear polymer with cationic groups. Therefore, it has physical and chemical functions such as adsorption, charge neutralization and ion exchange that neutral polymers do not have. Cationic polymer with a relatively fixed positive charge, with a negative charge of fibers, plastics and other surfaces have a strong binding force, is widely used as synthetic materials of antistatic agent, spinning agent, flocculant. A high molecular weight polydimethyldiallyl ammonium chloride polymer antistatic agent was synthesized by aqueous solution polymerization with high molecular weight, rapid dissolution, small residual monomer and excellent antistatic performance. Polydimethyldiallyl ammonium chloride is a kind of aldehyde-free and pollution-free color fixing agent, which can be used in the color fixing process of fabrics. However, in the process of color fixing, the reaction time and temperature as well as the pH of the color bath should be well controlled, so as to ensure the best color fastness and improve the effect of dyeing and color fixing.
