HPMA hydrolyzed polymaleic anhydride
Content:

Performance:


HPMA is a low molecular weight polyelectrolyte with a general relative molecular weight of 400-800. It is non-toxic, easily soluble in water, and has high chemical and thermal stability. The decomposition temperature is above 330 ℃. There is a significant solubility limit effect at high temperatures (<350 ℃) and high pH.


Usage:


HPMA is suitable for alkaline water quality or for use in combination with other drugs. HPMA still has good scale inhibition and dispersion effect on carbonates below 300 ℃, with a scale inhibition time of up to 100 hours. Due to its excellent scale inhibition and high temperature resistance, HPMA is widely used in flash distillation units for seawater desalination, as well as low-pressure boilers, steam locomotives, crude oil dehydration, water and oil pipelines, and industrial circulating cooling water. In addition, HPMA has a certain corrosion inhibition effect, and its combination with zinc salts has a better effect.


HPMA can also be used as a cement admixture and a salt alkali soil amendment.


Quality indicators:


HPMA


Usage:


HPMA is usually compounded with organic phosphonates at a concentration of 1-15ppm, and is used for circulating cooling water, oilfield water injection, crude oil dehydration treatment, and low-pressure boiler furnace treatment. It has a good effect on inhibiting scale formation and peeling off old scale, with a scale inhibition rate of up to 98%. When HPMA is combined with zinc salts, it can effectively prevent corrosion of carbon steel.


Packaging and storage:


Plastic bucket packaging, 30kg per bucket or determined by the user. The storage period is ten months.


Safety and Protection:


HPMA is acidic and should be avoided from contact with skin, eyes, etc. After contact, rinse with plenty of water.
