Ib puag ncig tus cwj pwm
Cov yam ntxwv txaus ntshai: flammable thaum kub kub ntawm qhov qhib hluav taws. Decomposition los ntawm tshav kub ua ib tug heev lom phosgene. Nyob rau hauv cov ntaub ntawv ntawm kub kub, lub siab nyob rau hauv lub thawv nce, thiab muaj kev txaus ntshai ntawm tawg thiab tawg.
Combustion (decomposition) khoom: carbon monoxide, carbon dioxide, hydrogen chloride, phosgene.
Environmental cuam tshuam: 1. Anthropogenic qhov chaw ntawm methylene chloride tuaj yeem muab tso rau hauv qhov chaw raws li cov tshuaj tua kab mob rau cov tshuaj tua kab mob, cov tshuaj pleev xim, thiab cov tshuaj degreasing hlau.
2. Huab cua dispersion: dichloromethane yuav hnov mob nrog hydroxyl radical thiab decompose thaum nkag mus rau hauv huab cua, nrog rau ib nrab-lub neej ntawm ob peb lub hlis.
3. Biological decomposition: dichloromethane reacts nrog sludge noob los yog activated sludge nyob rau hauv lub mob ntawm txaus oxygen, thiab nws yuav decompose tag nrho nyob rau hauv 6 teev mus rau 7 hnub.
4. Txawm hais tias tsis muaj cov ntaub ntawv tshawb fawb txog kev siv tshuaj lom neeg, nws tuaj yeem ua pov thawj tias yuav tsis muaj cov tshuaj lom neeg muaj pes tsawg leeg ntawm dichloromethane vim nws cov octanol qis thiab dej faib coefficient.
5. Tus kheej-dej/av volatile methylene chloride muaj siab heev Henry txoj cai tsis tu ncua thiab evaporates sai thiab tsis tu ncua ntawm dej nrog ib nrab-lub neej ntawm 3-5.6 teev.
Cim npe nrov: Lowes Methanol Methylene Diethyl Chloride, lwm tus neeg, manufacturers, hoobkas, hais, nqe, yuav
