Properties:.
1227 is slightly soluble in ethanol, souble in water. Its aqueous solution is slightly alkaline, easy deliquescence with chronic exposure to air and foam profusely when shaken. Fish eye shaped crystals will be precipitated on standing storage. 1227 also has properties of light resistance, pressure resistance, heat resistance and no volatility. Standard concentrates are manufactured as 40% or 50% w/w solutions, with a bitter taste and a faint almond to like odor and appearance to be colorless to light yellow viscous liquid..

.
Usage:.
As nonoxidizing boicide, dosage of 50 to 100mg/L is preferred; as sludge remover, 200 to 300mg/L is preferred, adequate organosilyl antifoaming agent should be added for this purpose. 1227 can be used together with other fungicides such as isothiazolinones, glutaraldegyde, dithionitrile methane for synergism, but cannot be used together with chlorophenols. There will be sewage after the addition of 1227 in circulating cool water. The sewage should be filtered or taken out in time to prevent the sediment at the bottom of the collecting tank when the foam disappears...

CAS NO: 26099 to 09 to 02 .
Other Names: HPMA; Hydrolyzed Polymaleic Anhydride; poly(maleicacid);Polymaleic Acid; MALEIC ACID POLYMER;Polymaleic Acid.
.
Properties:.
HPMA is a low molecular weight polymeride, with average molecular weight 400 to 800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330℃. HPMA has obvious threshold effect under high temperature (350℃) and high pH（8.3）level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300℃ with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement..
