Kev ua tau zoo

HEDPyog cov kab mob organophosphoric acid corrosion inhibitor. Nws tuaj yeem chelate nrog Fe, Cu, thiab Zn ions los tsim cov chelating ruaj khov tebchaw.Nws tuaj yeem yaj cov ntaub ntawv oxidized ntawm cov hlau no qhov chaw.HEDP qhia pom cov nplai zoo thiab qhov cuam tshuam los tiv thaiv corrosion nyob hauv qhov kub thiab txias 250 ℃. HEDPmuaj cov tshuaj lom neeg ruaj khov nyob rau hauv tus nqi siab pH, nyuaj rau ua kom dej hauv lub cev, thiab tsis yooj yim rau kev lwj hauv cov teeb pom kev zoo thiab kub. Nws cov kua qaub / alkali thiab chlorine oxidation kam rau ua tau zoo dua li ntawm lwm yam organophosphoric acids (ntsev).HEDPtuaj yeem hnov ​​mob nrog cov hlau ions hauv dej system tsim cov hexa-element chelating complex, nrog calcium ion hauv tshwj xeeb. Yog li ntawd,HEDPmuaj zoo antiscale thiab pom qhov pib zoo cuam tshuam. Thaum tsim ua ke nrog lwm cov tshuaj ntxuav dej, nws qhia tau cov teebmeem zoo synergistic. Lub xeev khov ntawmHEDPyog siv lead ua hmoov, haum rau kev siv nyob rau lub caij ntuj no thiab khov cheeb tsam. Vim tias nws cov purity siab, nws tuaj yeem raug siv los ua tus neeg sawv cev tu tsiaj hauv hluav taws xob teb thiab ntxiv rau cov tshuaj muaj yees hauv cov tshuaj txhua hnub.

Thov

HEDP yog siv raws li teev thiab xeb inhibition nyob rau hauv circulating txias dej system, roj teb thiab qis zog rhaub dej hauv cov teb xws li fais fab fais fab, kev lag luam chemical, metallurgy, chiv, thiab lwm yam. HEDPyog siv ua xab npum rau hlau thiab tsis yog hlau. Hauv dyeing kev lag luam,HEDPsiv raws li peroxide stabilizer thiab zas xim txhim kho tus neeg sawv cev; Hauv qhov tsis-cyanide electroplating,HEDPsiv raws li tus neeg saib xyuas chelating. Qhov ntau npaum ntawm 1-10mg / L nyiam dua li nplai inhibitor, 10-50mg / L ua xeb inhibitor, thiab 1000-2000mg / L ua tshuaj ntxuav tes. Feem ntau,HEDP yog siv ua ke nrog polycarboxylic acid.
