Product description: Hydyolytic polymaleic anhudride CAS NO. 26099-09-2 Other names： PolymaleicacidAq Hydrolysed Polymaleic Anhydride Hydrolyzed Polymaleic Anhydride Hydrolized polymaleic anhydride HPMA Polymaleic Acid Nature： Appearance: brown yellow transparent liquid Solid content: ≥50.0% Density（20℃）, g/cm3: 1.18 PH（1% aqueous solution）: 2.0~3.0 Average molecular weight: ≥300 Bromine number, mg/g: ≤160（first-rate product） Feature： This product is an organic fatty acid polymer, the general molecular weight is 400-800, easily soluble in water, chemical stability and high thermal stability, decomposition temperature is above 330℃, visible threshold effect at high temperatures (<351℃) and high PH (8.3 and above) or under the temperature and PH value. has good scale inhibition to carbonate and phosphate. The scale inhibition time is up to 100 hours , can be mixed with crude oil dewatering demulsifier. Less toxicity, no carcinogenic, teratogenic effects can be microbial degradation and the degradation products are harmless to humans and animals and aquatic animals. Purpose： This product is often compound with organic phosphonate at (2-5) mg / l. For circulating cooling water, oilfield water injection, crude oil dehydration, low pressure boiler furnace processing, has good effect of restraining scale formation and dissection of the old scale, inhibition rate is up to 98%. It compound with (1-2) mg / l zinc salts, can effectively prevent the carbon steel corrosion. It can be used as a textile system textiles bleaching agent can reduce the ash content of the textile. Packaging and Storage：This product is packaged by 125kg plastic bucket. Store in a cool room, storage for one year.
