Main Products

At present, the company has 1 domestic invention patent and 8 utility model patents, and has reached strategic cooperation with many scientific research institutions and industry associations. It can realize the industrialization of 50000 tons of seawater and brackish water reverse osmosis membrane scale inhibitor project, and its production capacity covers 20 billion cubic meters of desalinated water and industrial water, realizing water saving, carbon reduction, pollution reduction and efficiency enhancement.

Polyepoxysuccinic acid (sodium) PESA

It is a non-phosphorus, non-nitrogen green environmental protection multi-scale corrosion inhibitor. The water of calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, calcium fluoride and silica scale has good scale inhibition dispersion performance, scale inhibition effect is better than commonly used organic phosphine scale inhibitor.

Hydrolysis of maleic anhydride HPMA

Generally, the relative molecular weight is 400~800, non-toxic, easily soluble in water, high chemical stability and thermal stability, and the decomposition temperature is above 330 ℃. HPMA is suitable for alkaline environments. Due to its excellent scale inhibition performance and high temperature resistance, HPMA is widely used in desalination flash evaporation devices, low pressure boilers and industrial circulating cooling water. In addition, HPMA has a certain corrosion inhibition effect, and the corrosion inhibition effect is better when mixed with zinc salt.

Carboxylic sulfonic acid terpolymer AA/AMPS

Because the molecular structure contains a carboxylic acid group with good scale inhibition and dispersion performance and a sulfonic acid group with strong polarity, it can improve the calcium tolerance, have a significant scale inhibition effect on calcium phosphate, calcium carbonate, zinc scale in water, and prevent the deposition of iron oxide, especially for calcium phosphate scale inhibition rate. And excellent dispersion performance. Compound with organic phosphine, the synergistic effect is obvious. Especially suitable for high pH, high alkalinity, high hardness of water quality, is to achieve high concentration multiples of the ideal scale inhibitor dispersant. Can also be used as textile printing and dyeing auxiliaries; paper system pulp scale inhibitor.

Phosphono carboxylic acid, amido sulfonic acid copolymer PCA

It has good dispersion performance for calcium carbonate and calcium phosphate scale in circulating cooling water, and has good inhibition effect on the deposition of barium sulfate, strontium sulfate and silica scale, and has good thermal stability and strong chlorine resistance. It is widely used in scale inhibition and corrosion inhibition of industrial circulating cooling water system and oilfield reinjection water system; it is used in papermaking ceramics and other industries with better performance than acrylic products; it can also be used for scale inhibition on boilers.

2-hydroxy-2-phosphate acetic acid HPAA

Good chemical stability, not easy to hydrolysis, not easy to be destroyed by acid and alkali, safe and reliable, non-toxic and non-polluting, can improve the solubility of zinc, has a strong corrosion inhibition, corrosion inhibition performance is higher than HEDP, EDTMP. Mainly used as a metal cathode corrosion inhibitor, widely used in steel, petrochemical, electric power, pharmaceutical and other industries of the circulating cooling water system corrosion and scale inhibition, suitable for use as a low hardness in southern China, easy to corrode water corrosion inhibitor.
