CAS 79-01-6 Trichlorethylene (TCE) thiab CAS 127-18-4 tetrachlorethylene (PCE, los yog perchloroethylene) yog ob qho tib si siv cov tshuaj chlorinated cov kuab tshuaj hauv kev lag luam. Thaum lawv qhia cov khoom siv tshuaj zoo sib xws, lawv cov kev ua tau zoo, siv qhov sib txawv.
Trichlorethylene (TCE) yog dab tsi?
Trichlorethylene yog ib tug txiv neej- tsim tshuaj uas tsis tshwm sim nyob rau hauv ib puag ncig. Cov kua ntshiab, tsis muaj xim, tsis muaj hluav taws xob evaporates sai thiab muaj cov chloroform qab zib -zoo li ntxhiab.
Tetrachlorethylene (PCE) yog dab tsi?
Tetrachlorethylene (PCE) yog nonflammable, kua solvent dav siv nyob rau hauv qhuav tu, ntoo ua, fabric manufacturing, thiab hlau degreasing. Hauv tsev, nws tuaj yeem pom muaj nyob rau hauv suede tiv thaiv, pleev xim rau, cov rooj tog zaum stripper, dej tshuaj tua kab mob, silicone lubricants, tshuaj pleev ib ce, kua nplaum, thiab tshuaj ntxuav ntoo.
Qhov sib txawv tseem ceeb ntawm CAS 79-01-6TCE and CAS 127-18-4 PCE

Kev Siv Khoom Siv Sib txawv
CAS Nr .: 79-01-6Trichlorethylene (TCE) yog lub zog muaj zog organic hnyav. Nws feem ntau yog siv los tshem tawm cov roj, roj, thiab siv quav ciab los ntawm cov khoom siv hlau thiab tseem yog cov khoom siv raw rau kev tsim cov polyvinyl chloride (PVC), tshuaj tua kab, thiab nplaim hluav taws. Tsis tas li ntawd, nws tuaj yeem muab ntxiv rau cov nplaum tshwj xeeb, kho cov kua dej, cov xim, cov kua roj vanish, thiab cov xim tshem tawm.
CAS Nr .: 127-18-4Tetrachlorethylene (PCE / PERC) muaj cov khoom ruaj khov thiab muaj peev xwm ntxuav tau zoo. Nws yog ib qho tseem ceeb hnyav hauv tsoos tsho qhuav tu thiab yog dav siv rau chav degreasing hauv hlau tu. Hauv kev tsim tshuaj lom neeg, nws pab hauv kev npaj ntawm trichloroacetic acid thiab fluorinated compounds thiab kuj yog siv dav hauv aerosols, hnyav soaps, luam ntawv inks, adhesives, thiab sealants rau cov neeg siv khoom thiab cov khoom lag luam.
Nyem qhov no xa ib qho kev nug
Koj yuav tsum xaiv qhov twg?
Xaiv TCE hnyav yog tias koj xav tau:
Kev ziab sai sai thiab ua haujlwm sai
Precision tu (electronics, aerospace)
Muaj zog solvency rau lub teeb roj thiab residues
Xaiv PCE hnyav yog tias koj xav tau:
Kev ruaj ntseg tshuaj ntau dua
Slower evaporation rau ncua kev tu
Cov ntawv thov xws li textile qhuav tu lossis hnyav -lub luag haujlwm degreasing
