Proprjetajiet:

HEDP huwa inibitur tal-korrużjoni tal-aċidu organofosforiku. Jista 'chelate ma' joni Fe, Cu, u Zn biex jifforma komposti kelanti stabbli. Jista 'jxolji l-materjali ossidizzati fuq l-uċuħ ta' dawn il-metalli. HEDP juri skala eċċellenti u effetti ta 'inibizzjoni tal-korrużjoni taħt temperatura ta' 250 ℃. HEDP għandu stabbiltà kimika tajba taħt valur għoli ta 'pH, diffiċli biex jiġi idrolizzat, u diffiċli biex jiġi dekompost taħt kondizzjonijiet ta' dawl u sħana ordinarji. It-tolleranza tal-ossidazzjoni tal-aċidu/alkali u tal-kloru tagħha hija aħjar minn dik ta 'aċidi organofosforiċi oħra (melħ). 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.

L-istat solidu ta ' 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.

Użu:

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.

Sigurtà u protezzjoni:

HEDP huwa aċiduż. Oqgħod attent għall-protezzjoni tax-xogħol waqt it-tħaddim. Evita kuntatt mal-għajnejn u l-ġilda. Jekk titlaq fuq il-ġisem, laħlaħ immedjatament b'ħafna ilma.
