Properties:
There is C-P bond in the molecular structure, so ATMP has good chemical stability, not easy hydrolysis, high temperature resistance. Used with zinc salts and copolymers, it has good synergies and dissolve limited effect. The high dose 40~60mg/L of this product has good corrosion inhibition property and is non-toxic and pollution-free drug. This product has good dispersion and scale inhibition performance to calcium carbonate scale.
ATMP solid is crystalline powder, well soluble in water, easy to absorb moisture, easy to transport and use. Especially suitable for cold winter area. For the high purity, it can be used as metal chelator and metal surface treatment agent in textile printing and dyeing industry.
Use: This product is mainly used in the scale inhibitor of open circulating water cooling system. Also can be used in high hardness, large salinity, poor water quality oilfield waste water reinjection system and power plant condenser cooling water system.
