Dab tsi yog HFE Hydrofluoroether?
HFE (Hydrofluorohere, yog chav kawm ntawm cov organic sib xyaw ua ke ntawm hydrogen, fluorine, carbon thiab oxygen, sib xyaw-r ') thiab fluoroalkyl lug lug. Nws yog tsim los khaws cov kev ua tau zoo ntawm fluorinated cov kuab tshuaj thaum txo cov kev cuam tshuam ib puag ncig (xws li ozone txheej kev cuam tshuam thiab ntiaj teb sov sov muaj peev xwm). HFE tau dav siv raws li tus neeg sawv cev tu ua ntej, txias, feem ntau, tshwj xeeb hauv cov khoom siv hluav taws xob, tshwj xeeb hauv cov duab hluav taws xob thiab aerospace teb.
Cov yam ntxwv tseem ceeb ntawm HFE Hydrofluorochet
1. Dememical Stability
Tshav kub-resist, hydrolysis-resistant, tsis yooj yim los ua kom yooj yim nrog cov kua qaub, alkalis lossis oxidants, haum rau kev ntxuav kom huv.
Tsawg ncaj nro, tuaj yeem nkag sai sai ntawm cov khoob me me.
2.Qhov kev ua phooj ywg
ODP (ozone depletion muaj peev xwm) ≈ {0}}, tsis muaj chlorine lossis bromine, tsis ua kev puas tsuaj ozone txheej.
GWP (Ntiaj teb sov sov muaj peev xwm) yog tsawg, thiab GWP ntawm qee hfes yog qis dua li ntawm pfcs (perfluorinated tebchaw).
3.Physical Cov Khoom Siv
Dav boiling point ntau ntau (30 degree ~ 160 degree), cov qauv sib txawv tuaj yeem xaiv raws li kev xav tau.
Tsis-flammable los yog nyuaj rau hlawv, muaj kev nyab xeeb siab (tsis muaj flash taw tes lossis lub teeb nyem siab).
Zoo rwb thaiv tsev kev ua tau zoo, haum rau cov khoom siv hluav taws xob tu.
4.Low Toxicity
Cov tawv nqaij tsis tshua muaj khaus, cov khoom siv tsis tshua muaj zog (VOC) cov ntsiab lus, tab sis tseem yuav siv tau hauv qhov chaw cua.
