it is miscible with water. It shows excellent scale inhibition to calcium sulfate, calcium carbonate and barium sulfate. It’s worth mention that it still has good scale inhibition to calcium carbonate when the PH reaches 10-11. Compare with organic phosphonic acid salt it has four unique properties:
i. it still has good scale inhibition to calcium carbonate when the PH reaches 10-11, which is 1-2 times more than HEDP and ATMP.
ii. It shows excellent scale inhibition to barium sulfate.
iii. It shows better corrosion inhibition effects than HEDP and ATMP.
Scale and corrosion inhibitor in circulating cooling water and boiler water, as well as oilfield water, cooling water and boiler water with high barium carbonate. especially for the circulating cooling water with normal PH. it can also be used as stabilizer for peroxide and chlorine dioxide. When used alone, little scale sediment is found even none of dispersantis used.
(5) Packing and storage:
Packed in 25kg plastic bucket. It can be stored for 2 years.
