Perchlorethylene (PCE) - tseem hu ua PCE lossis perc - yog cov kua tsis muaj xim thiab cov tshuaj tsis haum nrog cov ntxhiab tsw qab. PCE yog cov kuab tshuaj uas tau siv dav rau cov neeg siv khoom siv xws li cov tshuab ntxhua khaub ncaws thiab cov nplaum, hauv kev lag luam xws li kev tu qhuav, thiab hauv ntau qhov chaw lag luam.
Perchlorethylene (PCE) Adhesive Txheej txheem cej luam
Perchlorethylenenplaum, tseem hu ua tetrachlorethylene nplaum los yog "perc" adhesive, yog ib qho kev lag luam - qib sib txuas tus neeg sawv cev ntev siv hauv kev tsim khoom.
Kev txhawj xeeb txog kev noj qab haus huv thiab ib puag ncig
Zoo li ntau cov kuab tshuaj ua lag luam, perchloroethylene-raws li cov nplaum nplaum tau ua rau muaj kev txhawj xeeb txog kev noj qab haus huv thiab ib puag ncig.
Cov kuab tshuaj muaj nyob rau hauv cov nplaum no yog ib qho tsis haum tshuaj organic (VOC) uas tuaj yeem ua rau muaj kev phom sij rau tib neeg thiab ib puag ncig. Thaum ua ntawv thov, cov kuab tshuaj evaporates yooj yim, tso vapors uas tuaj yeem nqus tau los ntawm cov neeg ua haujlwm lossis cov neeg nyob ze. Kev pov tseg tsis raug kuj tuaj yeem ua rau muaj dej paug.
Kev cai thiab kev txwv
Vim cov kev pheej hmoo no, ntau thaj tsam tau txwv lossis txwv tsis pub siv cov nplaum perchlorethylene. Qhov twg tso cai, lawv siv feem ntau txwv rau cov chaw tswj hwm nrog kev ntsuas kev nyab xeeb nruj. Txhawm rau txo qis VOC emissions, dej-raws li thiab qis-VOC cov nplaum tau raug siv los ua cov khoom siv nyab xeeb dua.
Cov ntawv thov kev lag luam
Txawm hais tias cov kev txwv no, qee qhov kev lag luam - tshwj xeeb hauv kev tsim tsheb thiab aerospace - txuas ntxiv siv perchlorethylene nplaum vim lawv qhov tshwj xeeb ua haujlwm ntev thiab tshuaj lom neeg. Cov nplaum nplaum no tshwj xeeb tshaj yog tsim rau cov khoom siv uas yuav tsum tau tiv taus qhov kub thiab txias. Txawm li cas los xij, kev tshawb fawb thiab kev tsim kho tseem tab tom nrhiav los txheeb xyuas cov ntaub ntawv hloov chaw nyab xeeb.
Xaus
Perchlorethylene (CAS 127-18-4)adhesives tau ua lub luag haujlwm tseem ceeb hauv kev lag luam kev sib raug zoo rau ntau xyoo, tab sis kev paub txog lawv txoj kev noj qab haus huv thiab kev pheej hmoo ntawm ib puag ncig tau ua rau cov kev cai nruj dua thiab kev tsim kho tshiab mus rau lwm txoj hauv kev.
