Kev siv ntawm PERCHLORETHYLENE

Hauv kev lag luam, PERCHLORETHYLENE feem ntau yog siv los ua cov kuab tshuaj, cov organic synthesis, hlau nqus tsev ntxhua khaub ncaws thiab cov ntxhua khaub ncaws qhuav, desulfurizer, cua sov nruab nrab.Nws yog siv rau kev kho mob raws li ib tug anthelmintic.Nws kuj yog ib qho nruab nrab ntawm trichlorethylene thiab fluorinated organic teeb meem.Cov neeg nyob hauv ib puag ncig tuaj yeem raug cov tetrachlorethylene tsawg tsawg los ntawm huab cua, zaub mov thiab dej haus.Tetrachlorethylene muaj zoo solubility rau ntau inorganic thiab organic tebchaw, xws li sulfur, iodine, mercuric chloride, txhuas chloride, rog, roj hmab thiab resin, xws li solubility yog dav siv los ua hlau degreasing tu tus neeg saib xyuas, xim stripping tus neeg saib xyuas, qhuav tu tus neeg saib xyuas, roj hmab hnyav. , ink solvent, kua xab npum, qib siab plaub thiab plaub degreasing;Tetrachlorethylene kuj tseem siv los ua cov tshuaj tua kab mob (hookworm thiab ginger worm);Finishing tus neeg saib xyuas rau kev ua textile.
1. Siv los ua cov kuab tshuaj organic, tus neeg saib xyuas kom qhuav, tus neeg saib xyuas cov roj extraction, tus neeg saib xyuas cov pa luam yeeb, desulfurizer thiab ntaub xov xov, thiab lwm yam
2. Tetrachlorethylene yog siv dav, feem ntau yog siv los ua cov kuab tshuaj organic, tus neeg saib xyuas kom qhuav, hlau degreasing hnyav, thiab tseem siv los ua enteroinsect repellent.Tetrachlorethylene tuaj yeem siv los ua cov khoom siv roj, tshuaj tua hluav taws thiab tshuaj ntsuam cov pa luam yeeb, thiab tseem tuaj yeem siv los ua cov trichlorethylene thiab fluorinated organic compounds.
3. Siv los ua cov kuab tshuaj organic, tus neeg saib xyuas kom qhuav, desulfurizer thiab ntaub xov xov
4. Tetrachlorethylene yog siv dav, feem ntau yog siv los ua cov kuab tshuaj organic, tshuaj ntxuav kom qhuav, hlau degreasing hnyav, kuj tseem siv los ua enteroinsect repellent tshuaj hnyav, chromatographic tshuaj xyuas cov qauv khoom.Tetrachlorethylene tuaj yeem siv los ua cov khoom siv roj, tshuaj tua hluav taws thiab tshuaj ntsuam cov pa luam yeeb, thiab tseem tuaj yeem siv los ua cov trichlorethylene thiab fluorinated organic compounds.
