Global - Prime Tetrachloroethylene: Cov Tshuaj Yaj Hauv Kev Lag Luam Tseem Ceeb
Cov Ntawv Thov Tseem Ceeb
Hauv kev lag luam ntxuav qhuav, tetrachloroethylene yog cov tshuaj yaj kub uas siv tau zoo tshaj plaws. Nws cov tshuaj yaj zoo heev ua rau nws yooj yim tawg thiab tshem tawm ntau yam xim av, txij li cov roj tawv ncauj ntawm cov ntaub zoo mus rau cov av uas nyob hauv cov xov. Nws cov nqi Kauri - Butanol (KB) siab ua kom huv si, thaum nws cov tshuaj lom tsawg ua rau muaj kev nyab xeeb dua rau cov neeg ua haujlwm. Cov saw hlau ntxuav qhuav loj hauv North America, Tebchaws Europe, thiab Asia vam khom peb cov tetrachloroethylene los muab cov txiaj ntsig zoo, khaws cia qhov zoo thiab qhov zoo ntawm cov khaub ncaws zoo nkauj.
Cov chaw ua hlau kuj tau txais txiaj ntsig zoo los ntawm peb cov tetrachloroethylene. Ua ib qho tshuaj ntxuav roj zoo, nws tshem tawm cov roj, cov roj nplua nyeem, thiab lwm yam kuab paug ntawm cov hlau. Hauv cov chaw tsim tsheb hauv lub teb chaws Yelemees thiab Nyiv Pooj, thiab cov chaw tsim khoom siv dav hlau hauv Tebchaws Meskas, nws npaj cov hlau rau cov txheej txheem xws li pleev xim, plating, thiab vuam, kom ntseeg tau tias muaj kev sib txuas zoo thiab cov khoom zoo. Los ntawm kev tshem tawm cov seem uas yuav ua rau xeb, nws ua rau lub neej ntawm cov khoom siv hlau ntev dua, txhim kho qhov ruaj khov ntawm cov khoom kawg.
Hauv kev tsim cov tshuaj lom neeg, tetrachloroethylene ua haujlwm ua ib qho tseem ceeb hauv nruab nrab. Nws cov qauv molecular tshwj xeeb tso cai rau ntau yam kev ua haujlwm, ua rau muaj kev tsim cov tshuaj tshwj xeeb, cov tshuaj txias, thiab cov polymers. Hauv kev tsim tshuaj thiab khoom siv hluav taws xob, nws siv los tsim cov kuab tshuaj purity siab rau cov txheej txheem tseem ceeb, ua kom ntseeg tau tias qhov tseeb thiab zoo ntawm cov khoom kawg. Piv txwv li, hauv kev tsim cov yas ua tau zoo rau kev lag luam hluav taws xob, cov tshuaj tetrachloroethylene pab txhawb rau lub zog ntawm cov khoom thiab kev tiv taus cua sov.
Peb cov tetrachloroethylene kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tshuaj xyuas ib puag ncig. Pom zoo ua ib qho hloov rau cov tshuaj uas ua rau ozone puas tsuaj, nws siv rau hauv kev kuaj dej thiab av los rho tawm thiab tshuaj xyuas cov pa phem uas muaj roj. Cov chaw soj nstuam ib puag ncig thoob ntiaj teb vam khom nws los ntsuas qhov tseeb ntawm cov pa phem, coj kev kho thiab ua kom ntseeg tau tias ua raws li txoj cai.
