water treatment chemical HPMA

Lvnon-508-MAH hydrolysis HPMACAS26099-09-02 Alias: polymaleic acid Dequest: P9000First, product performanceHPMA is a low-molecular-weight polyelectrolyte, in general the relative weight of 400 to 800, non-toxic, soluble in water, chemical stability and high thermal stability, the decomposition temperature in more than 330 C. In the high-temperature (<350 C) and high pH under the limit solution visible effect. HPMA apply to basic water or mixed with other drug use. HPMA in the 300C of the carbonate is still well below the spread and scale effects, the time scale of up to 100h. HPMA scale due to high temperature performance and high-performance, so the desalination plant and low-voltage flash boiler, steam, oil dehydration, water pipelines and industrial circulating cooling water to be widely used. In addition to a certain extent HPMA corrosion, zinc and mixed better.HPMA can also be used to cement admixtures.Second, the quality indicators in line with GB / T 10535-1997ItemIndicatorsAppearanceLight yellow to brown-red liquid and transparentSolid content % ≥48.0Bromine value mg/g ≤80.0Average molecular weight ≥450pH (1% aqueous solution)2.0-3.0Density(20C)g/cm3 ≥1.18Third, the use ofHPMA is usually 1 15ppm and organic compound bisphosphonates for the circulation of cooling water, oil field water injection, oil processing and dehydration of the low-pressure boiler furnace processing, has a good scale inhibition and to generate spin-off of the old scale, the rate of scale can be Up to 98%. HPMA when mixed with zinc to prevent corrosion of carbon steel.Fourth, security and protectionHPMA for the acid, and the skin should be avoided, such as the eyes contact, contact with a large number of applications after the rinse water.Five, packing and storageHPMA as a plastic barrel, 25kg, or by the user to determine. Storage for a period of 10 months.
