Xususiyatlari:

HEDP organofosforik kislota korroziya inhibitori hisoblanadi. U Fe, Cu va Zn ionlari bilan xelatlanib, barqaror xelatlovchi birikmalar hosil qilishi mumkin. Bu metallar yuzasida oksidlangan moddalarni eritishi mumkin. HEDP 250 ℃ haroratda mukammal o'lchov va korroziyaga qarshi ta'sir ko'rsatadi. HEDP yuqori pH qiymatida yaxshi kimyoviy barqarorlikka ega, gidrolizlanishi qiyin va oddiy yorug'lik va issiqlik sharoitida parchalanishi qiyin. Uning kislota/ishqor va xlor oksidlanishga chidamliligi boshqa fosfororganik kislotalarga (tuz) qaraganda yaxshiroq. 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.

ning qattiq holati 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.

Foydalanish:

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.

Xavfsizlik va himoya:

HEDP kislotali. Ish paytida mehnatni muhofaza qilishga e'tibor bering. Ko'z va teri bilan aloqa qilishdan saqlaning. Agar u tanaga sachrasa, darhol ko'p miqdorda suv bilan yuvib tashlang.
