Perchlorethylene (PCE) Txheej txheem cej luam
Perchloroethylene, tseem hu ua tetrachloroethylene, yog cov organic tshuaj siv dav hauv kev tu kom qhuav, hlau degreasing, thiab tsim ntau yam tshuaj thiab cov khoom siv. Nyob rau hauv chav tsev kub, nws yog ib tug uas tsis yog - cov kua flammable uas evaporates yooj yim thiab muaj ib tug ntse, qab zib tsw.
Perchlorethylene (PCE) Muaj:
PCE Dry Cleaning Solvent:
PCE yog cov kuab tshuaj ntau tshaj plaws nyob rau hauv qhuav-kev lag luam tu vim nws muaj peev xwm degreasing muaj zog, nruab nrab volatility, thiab tsis yog -flammable xwm. Nws hloov cov roj av ua ntej- cov kuab tshuaj raws li cov kuab tshuaj, txhim kho kev nyab xeeb kev ua haujlwm zoo heev.
Kev ua hlau:
Hauv kev lag luam xws li automotive thiab aerospace, PCE yog siv rau degreasing thiab kho nto ntawm precision hlau qhov chaw, zoo tshem cov roj, waxes, thiab lwm yam kab mob.
Tshuaj Synthesis:
PCE kuab tshuajua haujlwm li nruab nrab hauv kev tsim cov tub yees (xws li HFC-134a), tshuaj tua kab (xws li pentachlorophenol), thiab fluoropolymers. Txawm li cas los xij, nws txoj kev siv hauv daim teb no tau poob qis vim muaj kev tswj hwm ib puag ncig nruj.
Lwm yam kev siv:
Yav dhau los, PCE kuj tau siv los ua cov tshuaj tua kab thiab ua cov kuab tshuaj hauv cov ntawv luam tawm, txawm hais tias cov ntawv thov no tau hloov pauv los ntawm cov kev hloov hauv ib puag ncig ntau dua.
