DT-102 Sodium Hydrolyzed Polymaleic Anhydride
DT-102Hydrolyzed Polymaleic AnhydrideHydrolyzed Polymaleic Anhydride
1,Properties
DT-102is a sodium salt of maleic acid hydrolysis of poly, low molecular weight polyelectrolyte, generally relative molecular weight of400 to 800,non-toxic, soluble in water, high chemical stability and thermal stability, decomposition temperature330℃.In the high-temperature (<350 ℃) and highPHwere greatly limited effect dissolution.DT-102suitable for alkaline water or mixtures with other drugs to use.DT-102at300℃, the following is still good scale inhibition against carbonate dispersion, scale of time up to 100h.As theDT-102scale performance and high temperature performance, so the flash device in the desalination of sea water and low pressure boiler, steam locomotive, crude oil dehydration, water pipelines and industrial circulating cooling water are widely used.AlsoDT-102in the plastic recycling as a cleaning agent to use a special washing effects, showing excellent cleaning ability.DT-102can also be used for cement additives.

3,Using method
DT-102usuallyas 1 ~ 15ppm compounds with organic phosphate, used in circulating cooling water, oilfield water injection, crude oil dewatering and low-pressure boiler furnace processing, has good scale inhibition and stripping the old scale, inhibition rate up to98%.DT-102when used as a plastic detergent wash solution of1-2%in accordance to add.
4,Safety Protection
DT-102is neutral, avoid contact with eyes and skin ,once contacted,flush with water.
5, Package and Storage
Normally in 25kg plastic drum , or determined by the users.Storage for ten months.
