Through the introduction of phosphonic group into carboxylic group, PCA has good dispersion property for scale of calcium carbonate and calcium phosphate in circulating cool water system. It has good scale inhibition for barium sulfate, strontium sulfate and silica scale.PCA has advantages in wide range of water quality, chemical stability, strong chlorine tolerance, etc. PCA can be used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system.

HEMPA is an organophophoric acid, which exhibits excellent chelation, scale inhibition and corrosion inhibition. It is mainly used in oilfield, detergent / soap and metal treatment etc, especially useful in the water sytems with high level of dissolved iron and calcium. It is also compatible with methanol/water solution. When built together with other water treatment chemicals, it shows good synergistic effects.
HEMPA is usually used together with other organophosphoric acid, polycarboxylic acid and salt in different areas.250kg/drum; 1250kg/IBC; or customers' requirement. Storage for ten months in shady room and dry place.

PAPE is a new kind of water treatment chemicals. It has good scale and corrosion inhibition ability. Because more than one ployethylene glycol group is introduced into the molecular, the scale and corrosion inhibition for calcium scale is improved. It has good inhibition effect for barium and strontium scales. PAPE has good scale inhibition effect for calcium carbonate and calcium sulfate, PAPE can mix well with polycarboxylic acid, organophoronic acid, phosphate and zinc salt.

PAPE can be used as scale inhibitor for oilfield and industrial cool water system.

HMDTMPA is a white crystal powder at room temperature, slightly soluble in water, with solubility less than 5%.

HMDTMPA can inhibit most scale formation such as calcium carbonate, calcium sulfate, barium sulfate and ferric oxide. As water treatment chemicals, HMDTMPAis used as scale inhibitors for calcium sulfate and barium sulfate, for calcium sulfate in particular. It has high scale inhibition rate and can last for long effective time. HMDTMPA can be used for crush treatment in oilfield and for water treatment in boiler.

KR-2000 is the copolymer of acrylic-acrylate-sulfosate, it is a good scale inhibitor for calcium phosphate, calcium carbonate and other inorganic minerals. KR-2000 can effectively stabilize calcium phosphate in formula containing phosphate. It can also stabilize zinc in formula containing zinc. It can disperse inorganic microparticles without pH influence.

KR-2000 is an effective dispersant in all organic water treatment formula, it can be used as dispersant for minerals, stabilizer for calcium phosphate.

Usage:

KR-2000 can be used as scale inhibitor for circulating cool water and boiler water, for phosphate, zinc ion and inorganic minerals in particular. When used alone, the dosage of 10-30mg/L is preferred. When used in other fields, the dosage should be determined by experiment.
Package and Storage:

200L plastic drum,IBC(1000L),customers' requirement. Storage for ten months in shady room and dry place.
