Recirculating Cooling Water System HPMA

?
Properties:

?

1. HPMA is a low molecular weight polymeride, with average molecular?weight?400-800. No toxicity, solublein water, high chemical?and thermal stability,?decomposed temperature above 330°C.

?2. HPMA has obvious threshold effectunder high temperature (350°C) and high pH (8.3) level, suitable tobe used?in alkaline water system or built with agents. It has good scale inhibition?against carbonateandphosphate scales under temperature 300°C?with?effective time as long as 100 hours.

3. Due to its good scale inhibition and high?temperature tolerance properties, HPMA is widely used indesalination plant?of flash vaporization equipment, low pressure boiler, steam locomotive, crude?oilevaporation, petroleum pipeline,and industrial circulating cool water systems.

4. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement.

Usage:

HPMA is usually used together with organic phosphonate at dosage of 1-15ppm for circulating cool water system, oilfield fill water, crude oil dewatering and Iowpressure boilers. HPMA has good scale inhibition (98%) and scale stripping properties. When used together with zinc salts, it can effectively inhibit carbon steel corrosion.
