Use | This product has high chemical stability and temperature resistance, and has obvious solubility limit effect when pH value is 8.3. It can chelate calcium and magnesium plasma in water and has lattice distortion ability, which can improve the fluidity of sludge. It is especially suitable for scale inhibition in high-temperature water systems such as boiler water. Can be used as oil field water pipeline, circulating cooling water system and flash seawater desalination and other sediment inhibitors, scale inhibitors, etc., can also be used as a basic industrial detergent |

Tan transparent liquid. Soluble in water, chemical stability and high thermal stability, decomposition temperature of 330. 50% of the aqueous solution is light yellow viscous liquid, density is greater than or equal to 1. 2g/cm3,pH value is 1~2. HP-MA is a low molecular weight polyelectrolyte, non-toxic, soluble in water, high chemical and thermal stability, decomposition temperature above 330 ℃.
The polymerization was initiated in the presence of benzoyl peroxide with maleic anhydride as a raw material and toluene as a solvent.
efficient scale inhibitor. Mainly used in low-pressure boilers, industrial circulating cooling water systems, oil pipeline, crude oil dehydration and flash seawater desalination and other aspects of the scale inhibitor, and can be used as the main component of advanced cleaning agents, but also can be used as textile rinsing agent, reduces the ash content of textiles. HPMA still has good scale inhibition and dispersion effect on carbonate below 300 ℃, and the scale inhibition time can reach COOH. Due to the excellent scale inhibition performance and high temperature resistance of HPMA, it is widely used in the flash unit of seawater desalination and in the low pressure boiler, steam locomotive, crude oil dehydration, water transfer pipeline and industrial circulating cooling water. In addition, HPMA has a certain corrosion inhibition effect, and the effect of compound with zinc salt is better, which can effectively prevent the corrosion of carbon steel. HPMA is usually (1~15)× 10-6 and organic phosphate compound, for circulating cooling water, oil field water injection, crude oil dehydration treatment and low pressure boiler furnace treatment, it has a good effect of inhibiting scale formation and stripping old scale, and the scale inhibition rate can reach 98%.
HPMA is acidic, should avoid contact with the skin, eyes, etc., after contact with a large number of water rinse.
