HEDP is an organ phosphoric acid corrosion inhibitor. It can chelate with FE, cu, and ZN ions to form stable chelating compounds. It can dissolve the oxidized materials on these metals surfaces. HEDP shows excellent scale and corrosion inhibition effects under temperature 250¡æ. HEDP has good chemical stability under high ph value, hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. Its acid/alkali and chlorine oxidation tolerance are better than that of other organ phosphoric acids (salt). HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects. The solid state of HEDP is crystal powder, suitable for usage in winter and freezing districts. Because of its high purity, it can be used as cleaning agent in electronic fields and as additives in daily chemicals.

PBTCA has low content of phosphoric, has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphates. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy. Appearance: Colorless or light yellow transparent liquid Active acid : 50.0 min Phosphorous acid as PO33-%: 0.8 max Phosphorous acid as PO43-%: 0.5 max Density 20¡æg/cm3: 1.27 min pH 1 solution: 1.5~2.0.
HPMA is a low molecular weight polymeride, with average molecular weight 400-800. No toxicity, soluble in water, high chemical and thermal stability, decomposed temperature above 330¡æ. HPMA has obvious threshold effect under high temperature (350¡æ) and high pH£¨8.3£©level, suitable to be used in alkaline water system or built with agents. It has good scale inhibition against carbonate and phosphate scales under temperature 300¡æ with effective time as long as 100 hours. Due to its good scale inhibition and high temperature tolerance properties, HPMA is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive, crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems. In addition, HPMA has good corrosion inhibition effect when used together with zinc salt. HPMA can also used as additives for cement. Appearance : Clear to umber transparent liquid Solid content % : 48.0 min Bromine value mg/g : 80.0 max Average molecular weight : 450 min pH 1 solution : 2.0-3.0 Density 20¡æ g/cm3 : 1.18 min.
Isothiazolinones is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect of Isothiazolinones is carried out through breaking the bond between bacteria and algae protein. When contacted with microbes, Isothiazolinones can quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones has strong inhibition and biocidal effects on ordinary bacteria, fungi and alga, and has many advantages such as high biocidal efficiency, good degradation, no residual, safety in operation, good compatibleness, good stabilization, low cost in operation. Isothiazolinones can mix with chlorine and most caution, anion, and non-ionic surfactants. When used at high dosage, its biosludge stripping effect is excellent. Isothiazolinones is a kind of fungicidal with properties of broad spectrum, high efficiency, low toxicity and non-oxidative, it is the ideal biocidal in industrial circulating cool water system and in wastewater treatment in oilfield, papermaking, pesticide, cutting oil, leather, detergent and cosmetics etc. Grade I : Grade II Appearance : Amber transparent liquid : Light yellow or light green transparent liquid Active content % : 14.0 min : 1.50 min pH value(as it) : 1.0-4.0 : 2.0-5.0 Density (20¡æ)g/cm3 : 1.25 min : 1.02 min CMI/MI (wt %) : 2.5-4.0 : 2.5-4.0.
