DT-202 Scale and corrosion inhibitor for mid-high hardness water
DT-202Scale and corrosion inhibitor for mid-high hardness water
1,Properties:
It is compounded by sulfosalt Copolymer, organic phosphorus acid, carboxylic acid copolymer and copper corrosion inhibitor.
It has a good chelating and dispersing effect to calcium carbonate and calcium phosphate etc.
It has a good corrosion inhibiting effect to carbon steel and copper.
Under higher PH value, it has good stability to zin salt. It is a high effective water treatment chemicals with double functionof corrosion and scale inhibition.
