Khoom:

HEDP yog organophosphoric acid corrosion inhibitor. Nws tuaj yeem chelate nrog Fe, Cu, thiab Zn ions los tsim cov chelate ruaj khov. HEDP qhia tau hais tias zoo heev nplai thiab corrosion inhibition cuam tshuam nyob rau hauv kub 250 ℃. HEDP muaj tshuaj lom neeg ruaj khov nyob rau hauv siab pH tus nqi, nyuaj rau hydrolyzed, thiab nyuaj rau decomposed nyob rau hauv lub teeb pom kev zoo thiab cua sov. Nws cov kua qaub / alkali thiab chlorine oxidation kam rau ua zoo dua li lwm cov organophosphoric acids (ntsev). 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.

Lub xeev muaj zog ntawm 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.

Kev siv:

HEDP is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating, HEDP is used as chelating agent. The dosage of 1-10mg/L is preferred as scale inhibitor, 10-50mg/L as corrosion inhibitor, and 1000-2000mg/L as detergent. Usually, HEDP is used together with polycarboxylic acid.

Ntim thiab khaws cia:

HEDP liquid: 200L plastic drum,IBC(1000L),customers’ requirement.

HEDP solid: 25kg/bag,customers’ requirement.

Cia rau kaum ob lub hlis nyob rau hauv chav tsev shady thiab qhuav qhov chaw.

Kev nyab xeeb thiab kev tiv thaiv:

HEDP yog acidic. Ua tib zoo saib xyuas kev tiv thaiv kev ua haujlwm thaum ua haujlwm. Tsis txhob kov qhov muag thiab tawv nqaij. Yog hais tias nws txaws rau ntawm lub cev, yaug tam sim ntawd nrog dej ntau.
