Taw qhia rau Perfluorohexanone (fK 5 1 12) thiab Heptafluoropropane (hFC 227ea)
Perfluorohexanone (FK 5 1 12) yog cov kua nyob rau hauv chav tsev kub, yooj yim vaporized thiab muaj nyob rau hauv gaseous lub xeev, thiab tsuas yog tso siab rau tshuaj inhibition thiab txias kom ua tiav cov nyhuv ntawm tua hluav taws. Hais txog kev tiv thaiv ib puag ncig, FK-5-1-12 yog qhov tseeb ntsuab thiab ib puag ncig tus phooj ywg tua hluav taws. Cov hluav taws tua hluav taws kub ntawm perfluorohexanone yog 4-6%, thiab cov npoo kev nyab xeeb yog qhov siab, uas muaj kev nyab xeeb rau tib neeg lub cev thaum siv. FK5 1 12 tuaj yeem khaws cia thiab thauj mus rau hauv cov thawv zoo tib yam nyob rau hauv lub siab ib txwm, tsis zoo li lwm yam kev xaiv uas yuav tsum tau muaj cov hlab ntsha siab rau kev khaws cia thiab kev thauj mus los.
Heptafluoropropane yog ib qho roj ntawm chav tsev kub, tsis muaj xim, tsis muaj ntxhiab, tsis muaj hluav taws xob thiab tsis muaj corrosive. Nws cov txheej txheem tua hluav taws yog cov tshuaj tua kab mob tshwj xeeb, thiab HFC 227ea muaj kev tua hluav taws ceev ceev, uas yog qhov zoo rau kev tiv thaiv cov khoom siv hluav taws xob thiab cov khoom muaj nqis, thiab muaj kev huv thiab rwb thaiv tsev zoo. Thaum ntxov xyoo 1990, cov teb chaws tsim muaj kev lag luam thawj zaug siv heptafluoropropane los hloov lub tshuab tua hluav taws halon thiab ua tiav.
Tam sim no, heptafluoropropane yog lub ntsiab hluav taws tua hluav taws hauv Suav teb.
Daim ntawv thov tua hluav taws
Cov nyhuv tua hluav taws - sib npaug
Hais txog kev tua hluav taws, tsis muaj qhov txawv txav ntawm perfluorohexanone thiab heptafluoropropane. Raws li Lin Zhen tsab xov xwm "Kev tshuaj xyuas thiab Kev Tshawb Fawb Txog Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob thaum perfluorohexanone muaj qhov ua kom txias txias zoo dua. Txawm li cas los xij, ob qho tib si perfluorohexanone thiab heptafluoropropane tuaj yeem tua cov nplaim hluav taws ntawm lithium roj teeb li ntawm ib nrab ib feeb, thiab ob qho tib si txo qhov kub thiab txias txog li 80 degrees, ua tiav lub hom phiaj ntawm kev thim rov qab ignition.
Cov tshuaj tua hluav taws tua hluav taws-HFC-227ea yog paub tab thiab txhim khu kev qha
HFC227ea hluav taws tua hluav taws tau muab faib ua cov kav dej thiab cov twj tua hluav taws uas tsis yog cov kav dej tua hluav taws, nrog rau ntau qhov kev thov ntau dua; nyob rau hauv sib piv, perfluorohexane tam sim no tsuas muaj ib tug uas tsis yog-pipeline tua hluav taws ntaus ntawv nyob rau hauv Tuam Tshoj.
Tsis tas li ntawd, perfluorohexanone muaj cov kev xav tau siab dua rau kev tswj cov dej. Kev tswj cov dej yuav tsum tau ua kom zoo thaum lub sij hawm ntim thiab khaws cov tshuaj tua hluav taws. Yog tias nws tsis raug tswj xyuas kom zoo, cov tshuaj acidic tau yooj yim tsim thiab cov thawv ntim khoom yog corroded. Cov txheej txheem tsim muaj peev xwm yuav tsum muaj siab. Yog tias cov qauv tsim tsis tsim nyog, tus neeg sawv cev tua hluav taws yuav tsis zoo thaum txau, yog li cuam tshuam rau kev tua hluav taws.
System Economy-HFC-227ea yog tus nqi zoo
Raws li kev paub dhau los, qhov hluav taws kub tua hluav taws loj ntawm perfluorohexanone siab dua li ntawm heptafluoropropane. Txhawm rau tua hluav taws tib yam, xav tau koob tshuaj ntau dua nyob rau ib lub sijhawm, thiab tus nqi ntawm tus neeg sawv cev rau ib chav tsev qhov hnyav kuj tseem siab dua li ntawm heptafluoropropane, yog li tag nrho cov nqi-zoo yog tsawg.
Environmental performance-perfluorohexanone yog ib puag ncig tus phooj ywg
Nyob rau hauv cov huab cua, perfluorohexanone tuaj yeem decompose nyob rau hauv tsib hnub, thaum heptafluoropropane tuaj yeem nyob hauv qhov chaw rau ntau tshaj 30 xyoo. Hauv kev sib piv, perfluorohexanone yog ib puag ncig zoo dua.
xaus
Hais txog kev tua hluav taws, tag nrho cov nyhuv ntawm perfluorohexanone thiab heptafluoropropane tsis txawv ntau, thiab txhua tus muaj nws qhov zoo thiab qhov tsis zoo ntawm cov ntsiab lus. Nyob rau hauv cov nqe lus ntawm daim ntawv thov, perfluorohexanone thiab heptafluoropropane yog ob qho tib si hluav taws xob tua hluav taws: heptafluoropropane feem ntau yog siv hauv Suav teb, uas feem ntau yog los ntawm kev xaiv kev lag luam. Heptafluoropropane muaj cov nqi ua haujlwm siab, ua tiav cov qauv thiab paub tab technology. Feem ntau lub teb chaws txawv teb chaws siv perfluorohexanone, feem ntau yog rau kev tiv thaiv ib puag ncig. Nyob rau hauv lub neej yav tom ntej, domestic perfluorohexanone tua hluav taws cov neeg ua hauj lwm kuj yuav tsim.
Rau cov ntawv thov tua hluav taws hauv thaj chaw tshiab, xws li lub zog cia, ob qho tib si perfluorohexanone thiab heptafluoropropane muaj cov ntawv thov. Qhov kev daws teeb meem twg yuav tau txais los ntawm lub ntsiab lus yav tom ntej yuav kawg nyob ntawm kev xaiv kev lag luam.
