Property and Uses
HP MA generally has a relative molecular weight of 400-800, is non-toxic, easily soluble in water, has high chemical and thermal stability, and decomposes at temperatures above 330°C.
HP MA is suitable for alkaline environments. Due to HP MA's excellent scale resistance and high-temperature resistance, it is widely used in flash distillation units for seawater desalination, low-pressure boilers, and industrial circulating cooling water. Additionally, HP MA has certain corrosion inhibitory effects, and combining it with zinc salts provides better corrosion inhibition.
HP MA can also be used as a cement admixture and saline-alkali soil conditioner.

How to use
When used alone, HP MA typically has a concentration of 1-15 mg/L, often combined with organophosphates, and is used for circulating cooling water treatment and internal treatment in low-pressure furnaces. It effectively inhibits scale formation and removes old scale, with an inhibition rate of up to 98%. When EDTMPS and HP MA are blended in a 1:3 ratio, it can be used for water treatment inside low-pressure furnaces. When HP MA is combined with zinc salts, it can effectively prevent corrosion of carbon steel.
Packaging and storage
HP MA is packaged in plastic barrels, with each drum weighing 25kg or 250kg, or depending on user requirements. The storage period is twelve months.
Safety protection
HP MA is acidic; pay attention to labor protection during operation, avoid contact with skin and eyes, and rinse thoroughly with plenty of water after contact
