(HPMA)

General Information

Synonym: HPMA

Common Trade Name: Belclene 200

CAS No.: 26099-09-2

Molecular Formula: 

Structure:

Properties:
The product an organic aliphatic acid polymeride, has its molecular weight in the range of 400-800. It is easily soluble in water, and possesses high chemical and thermal stability. Since its dissociation temperature is above 330℃, the product exhibits obvious threshold effects even under high temperature (＜350℃＝and high pH（8.3）value, It shows good scaling-prevention capability against carbonate and phosphate containing scales, and the effective time can be as ling as 100 hours. This products can be used together with the dewatering demulsifiers for crude oil. Furthermore, the products of the degradation are harmless to water lives as well as people and live-stocks.

 

Usage: This product is usually used at a concentration of 2~5ppm together with phosphonate, in systems like circulating cooling water, oilfield fill water, crude oil dewatering and inside-the-furnace trace treatment of low-pressure boilers. It has good scaling-prevention and descaling capability, with scaling prevention rate of 98%. When it is used with 1~2ppm of zinc salts, it can effectively inhibit corrosion of carbon steel. The product, can also be used as bleaching agent in textile industry to reduce the dust content in the products.
