DMDAAC (dimethyldiallylammonium chloride) has a wide range of applications and there are not many domestic manufacturers.

DMDAAC (dimethyldiallylammonium chloride), as a water-soluble cation, relies on the combination of polymer skeleton structure and hydrophilic functional groups to achieve flocculation and coagulation, thickening and drag reduction, dispersion and emulsification, Charge bonding and ion exchange, thereby playing important roles in solid-liquid separation, sludge separation, oil-water separation, charge bonding and ion exchange, scale and corrosion inhibition, surface modification, etc., and can be widely used in oil exploration, papermaking, mining, etc. Textile printing and dyeing, daily chemicals and water treatment and other fields.

Among them, in the field of oil extraction, DMDAAC (dimethyldiallylammonium chloride) can be used as a temperature-resistant and salt-resistant drilling fluid treatment agent, oil well cement admixture, acidizing fracturing additive and oil displacing agent; in the field of textile printing and dyeing , DMDAAC can be used as a formaldehyde-free color fixing agent to form a film on the fabric to improve the dye fastness; in the papermaking field, DMDAAC can be used as a retention agent; in the water treatment process, DMDAAC can be used for decolorization, flocculation and purification; in Japan Among chemicals, DMDAAC can be used as a combing agent, wetting agent and antistatic agent in shampoos.

According to the“China DMDAAC (Dimethyldiallyl Ammonium Chloride) Industry Market In-depth Research and Development Prospects Forecast Report 2022-2027” released by the Industrial Research Center It shows that currently, the common DMDAAC on the market is 60% and 65% aqueous solutions. Among them, domestic companies mostly use DMDAAC with 60% content, while most exported DMDAAC products are 65%. % content of the product.

From the perspective of production companies, there are not many domestic companies producing DMDAAC (dimethyldiallylammonium chloride). The main companies include Shandong Luyue Chemical Group Co., Ltd., Jiangsu Fumiao Technology Co., Ltd., and Shandong Baomo Biochemical Industry Co., Ltd., Zhejiang Dachuan New Materials Co., Ltd., Mingxiang Chemical Technology (Shandong) Group Co., Ltd., etc. Among them, Shandong Luyue Chemical Group Co., Ltd. has a DMDAAC production capacity of 30,000 tons/year; Jiangsu Fumiao Technology Co., Ltd. has a DMDAAC production capacity of 20,000 tons/year.

From the perspective of DMDAAC downstream applications, DMDAAC, as a cationic monomer, is usually polymerized with other monomers to form DMDAAC homopolymer PDMDAAC or DMDAAC copolymer. For example, DMDAAC reacts with acrylamide (AM) to form copolymer PDA. Among them, PDMDAAC, the homopolymer of DMDAAC, has the characteristics of safety, non-toxic, easily soluble in water, non-flammable, strong cohesion, good hydrolytic stability, non-gelling, insensitive to changes in pH value, and chlorine resistance, and has many applications. Used as a cationic coagulant in the sewage treatment industry.

Industrial analysts said that DMDAAC is one of the commonly used cationic monomers. It has high positive charge density, good water solubility, and easy molecular weight. Compared with other cationic monomers due to its advantages such as control, non-toxicity, and low cost, the demand for DMDAAC in the domestic market, especially in the water treatment field, is relatively large at this stage. In the future, as the country attaches greater importance to sewage and wastewater treatment and resource utilization, and the demand for water treatment in industrial production, municipal administration and other fields further expands, the application of DMDAAC in the water treatment field will further increase.
