Polyaspartic acid market worth exploiting

Polyaspartic acid is an amino acid polymer that naturally exists in mollusks and shells. In recent years, people have been inspired by animal metabolism and successfully synthesized this biopolymer material. Its greatest feature is that it is biodegradable, non-toxic and will not damage the ecological environment. The American company Donlar and Germany's Bayer have already achieved large-scale industrial production of polyaspartic acid, and domestic companies have also achieved industrial production. The production capacity of Shijiazhuang Desai Chemical Co., Ltd. is 3,000 tons per year. With the continuous improvement of global environmental awareness, the application of polyaspartic acid is extremely promising.

Polyaspartic acid is a polymer derived from the dehydration of the amino and carboxyl groups of the monomer of the domesine amino acid. At present, there are mainly two processes for the synthesis of polyaspartic acid: one is the L-aspartic acid method, L-aspartic acid is used as raw material, and polyaspartic acid is prepared through steps such as thermal catalyzed polycondensation, hydrolysis, and neutralization; and the other is maleic anhydride method. Maleic anhydride and organic amines are used as raw materials, condensed, Hydrolysis, neutralization and other steps to obtain polyaspartic acid. The second process has simple production equipment, low cost, and basically no "three wastes" emissions, and is a green chemical production process.

Polyaspartic acid is widely used and has high application value in many fields such as water treatment, medicine, agriculture and daily chemical. Polyaspartic acid is used as a green water treatment aid. Its main function is scale inhibition, dispersion and corrosion inhibition. It is particularly suitable for inhibiting calcium carbonate scale, calcium sulfate scale, cooling water, boiler water, and reverse osmosis water. The formation of barium sulfate scale and calcium phosphate scale has an efficiency of almost 100% for scale inhibition of calcium carbonate, and the effect is very good. Polyaspartic acid is also used in water treatment scale inhibition and also has a good dispersion and can effectively prevent corrosion of metal equipment. In addition, there is a synergistic effect of polyaspartic acid and organophosphorus corrosion and scale inhibitors, and polyaspartic acid is often formulated with other corrosion and scale inhibitors as an efficient, multi-functional corrosion and scale inhibitor.

Polyaspartic acid can be used as a fertilizer synergist in agriculture. Polyaspartic acid has a chelating effect on metal ions, and a certain molecular weight of polyaspartic acid can enrich nitrogen, phosphorus, potassium and other trace elements in the soil to provide plants with more efficient use of fertilizers. To achieve the effect of increasing crop yields and improving quality. In addition, polyaspartic acid can also be combined with a variety of insecticides, which can not only increase the efficacy, but also increase the yield and improve the quality of crops. It also has the effect of reducing the labor intensity by using multiple sprays.

The application of polyaspartic acid in the daily chemical industry is mainly used as a cleaning and washing aid. Polyaspartic acid has the functions of water softening, dirt dispersion and anti-fouling so that it can be used as a good substitute for phosphorus detergents, and because it is non-toxic and non-irritating, it can be used to harm humans. The production of detergents. The application of polyaspartic acid in the medical and health industry is as a drug carrier, mainly to stabilize the effect of anti-tumor drugs, and to prevent electrochemical physiochemical changes of the amine-containing thiol-based substances to protect small blood vessels. In addition, polyaspartate has inhibitory effects on gentamicin interference in the metabolism of phospholipids in the cochlea. As a new type of polymer, polyaspartic acid can react with a cross-linking agent to further synthesize superabsorbent, which can meet the requirements of non-toxic superabsorbent resin for hygienic products, and it can be degraded and can be used as a plant after degradation. fertilizer. In addition, polyaspartic acid also has many uses in oil extraction, textile printing and dyeing, and coatings.

The production of polyaspartic acid in foreign countries has been large-scaled, the product variety has been serialized, and the scale of domestic devices is still very small, especially in the application of polyaspartic acid research and promotion is not yet in place, the domestic polyaspartic ammonia Most of the research on the application of acid has only stayed in the laboratory stage, which has seriously affected the marketing efforts. Relevant scientific research units and enterprises should actively join forces to accelerate the development of polyaspartic acid and market application and promotion, and jointly promote the rapid and healthy development of China's polyaspartic acid industry.
