Priodweddau:

HEDP yn atalydd cyrydiad asid organoffosfforig. Gall chelate ag ïonau Fe, Cu, a Zn i ffurfio cyfansoddion chelating sefydlog. Gall hydoddi'r deunyddiau ocsidiedig ar arwynebau'r metelau hyn. HEDP yn dangos graddfa ardderchog ac effeithiau atal cyrydiad o dan dymheredd 250 ℃. HEDP â sefydlogrwydd cemegol da o dan werth pH uchel, yn anodd ei hydrolyzeiddio, ac yn anodd ei ddadelfennu o dan amodau golau a gwres cyffredin. Mae ei oddefgarwch ocsidiad asid/alcali a chlorin yn well na goddefiant asidau organoffosfforig eraill (halen). 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.

Cyflwr solet 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.

Defnydd:

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.

Diogelwch ac amddiffyn:

Mae HEDP yn asidig. Rhowch sylw i amddiffyniad llafur yn ystod y llawdriniaeth. Osgoi cysylltiad â llygaid a chroen. Os yw'n tasgu ar y corff, rinsiwch ar unwaith gyda digon o ddŵr.
