T-225 is copolymer of polyacrylic acid and hydroxypropyl acrylate, it has good scale inhibition and dispersion properties to calcium phosphate and calcium carbonate, it has good dispersion properties to ferric oxide sludge, clay and grease. T-225 can be used under high pH situation and has good compatibility with other organophosphines and BTA, T-225 can effectively withhold sediments of zinc salt and calcium phosphate, it has good scale inhibition and dispersion properties under high temperature and alkaline situations.
T-225 can be used in circulating cool water system in situation of alkaline and excess of phosphate. It can be used as scale inhibitor and dispersant for heater, none-column evaporator boiler, circulating cool water and oilfield dirty refilling water with high calcium content. The dosage of 10~30mg/L is preferred. It can be built with organophosphines to form full organic alkaline formula.

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.
