Properties:

HEDP inonzi organophosphoric acid corrosion inhibitor. Inogona chelate neFe, Cu, uye Zn ions kuti igadzire yakagadzikana chelating makomisheni.Inogona kunyungudutsa oxidized zvinhu pane aya masimbi. HEDP inoratidza yakanakisa chiyero uye corrosion inhibition mhedzisiro pasi petembiricha 250 ℃. HEDP ine kugadzikana kwakanaka kwemakemikari pasi pehupamhi hwepH, yakaoma kuita hydrolyzed, uye yakaoma kuodzwa pasi pechiedza chakajairwa uye mamiriro ekupisa. Asidhi yayo / alkali uye chlorine oxidation kushivirira zviri nani pane zveimwe organophosphoric acids (munyu). 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.

Mamiriro akasimba e 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.

Kushandisa:

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.

Kurongedza uye kuchengetedza:

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

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

Kuchengetedza kwemwedzi gumi nembiri muimba ine mumvuri uye yakaoma.

Chengetedzo nekudzivirira:

HEDP ine acidic. Ngwarira kuchengetedzwa kwebasa panguva yekushanda. Dzivisa kusangana nemaziso uye ganda. Kana ikapfachura pamuviri, sukurudza ipapo nemvura yakawanda.
