CAS 75-09-2 DICHLOROMETHANE (DCM), Methylene chloride, yog ib qho tsis muaj kob, volatile organic compound (ch₂ccl₂). Nrog lub qab zib thiab qab ntxiag aroma, nws yog feem ntau siv raws li cov kuab tshuaj nyob rau ntau yam kev lag luam thiab kev kuaj mob. Denser tshaj li huab cua thiab khav theeb ib qho npau npau ntawm 39.8 degree, dichhloromethans yog qhov ua tau zoo rau cov tebchaw rhiab rau kev nce siab kub. Ib qho ntxiv, nws nquag ua hauj lwm raws li cov xim txheej txheem kab txaij, degreaser, thiab hauv kev tsim ua npuas ncauj ua npuas ncauj thiab cov resins.
Dichhloromethane Hnyav Rau Kev Lag Luam Daim Ntawv Thov
Xim Stripping: Keeb kwm, DCM Dichhloromshane feem ntau siv yog nyob rau hauv cov xim pleev xim vim nws siv ntau hom xim yam tsis muaj kev ua kom cov khoom tawg. Nws siv nyob rau hauv cov neeg siv khoom haus luam yeeb tau raug txwv nyob rau ntau lub tebchaws, suav nrog Asmeskas thiab EU, vim muaj kev txhawj xeeb txog kev nyab xeeb.
Kev muaj degreasing: methylene chloride yog siv los ua cov kuab tshuaj rau degreast cov av thiab chaw nyob rau hauv kev tsim cov txheej txheem.
Tshuaj lom neeg: DCM pabcuam ua cov txheej txheem hnyav hauv kev tsim cov tshuaj ntawm cov kws tshuaj, tshuaj ntsuab, thiab lwm yam tshuaj lom neeg. Nws kuj tseem siv los ua cov kuab tshuaj uas muaj cov kuab tshuaj zoo li caffeine (los tsim cov kas fes dogsinated), hops, thiab tsw.
Cov nplaum thiab cov nplooj ntawv aerosols: cov khoom tseem ceeb hauv ntau cov nplaum muaj, thiab raws li lub tshuab ua npuas rau polyurethane ua npuas.
Cov plastics kev tsim khoom: Methylene chloride (CAS-09-2) yog siv nyob rau hauv kev tsim polycarbonate plastics thiab raws li cov kuab tshuaj rau cellulose acetate.
Zaj duab xis: keeb kwm siv hauv kev lag luam yees duab.
Ntim kom tau raws li cov qauv kev nyab xeeb thiab muaj nyob hauv ntau lub thawv ntau thiab tsawg, peb methylene chloride ua kom zoo sib xws, kev ua tau zoo hauv kev xav tau cov txheej txheem. Txhua zaus yuav tsum siv qhov cua kom zoo thiab ua raws li txhua yam kev nyab xeeb kev nyab xeeb.
