Khoom Taw Qhia
Rich Chemical yog ib tus kws tshaj lij Tuam Tshoj cov khoom lag luam qib dichloromethane ua nyob rau hauv Suav teb, uas tau koom nrog cov tshuaj organic rau 10 xyoo. Muab cov qauv dawb, peb zoo siab tos txais koj los yuav cov khoom zoo CAS No. chemicals nrog purity siab thiab tus nqi qis nrog peb.
Khoom nthuav dav
Cov mis mos molecular: CH2CL2
Molecular Luj: 84.93
Lub cev thiab cov khoom siv tshuaj lom neeg: cov xim tsis muaj pob tshab tsis muaj kuab lom, zoo ib yam li cov ntxhiab tsw ntawm ether thiab qab zib.
Tus txheeb ze ntom ntom: D4201.326Kg / L.
Kub taw tes: 40.4 ° C.
melting point: -96.7 degrees, ignition point ntawm 615 DEG C. me ntsis soluble nyob rau hauv dej, soluble nyob rau hauv ethanol, ethyl ether, lom, narcotic stimulation. Dichloromethane thiab dej hydrolysis cov tshuaj tiv thaiv, dichloromethane muaj kev lag luam ruaj khov, tiv thaiv hydrolysis. Dichloromethane thiab siab concentration oxygen yuav tsim explosive sib tov, tab sis tsis flammable, yog feem ntau siv nyob rau hauv kev lag luam ntawm tsawg toxicity, tsis flammable hnyav thiab tsawg boiling point.
Lub hom phiaj
Rau cov kuab tshuaj uas tsis yog flammable: hlau tu, xim tshem tawm, hlau degreasing tus neeg saib xyuas, peb cellulose acetate hnyav; zaj duab xis, aerosol, tshuaj tua kab mob thiab cov vitamins hauv kev tsim cov kuab tshuaj; foaming tus neeg sawv cev rau foaming rau zus tau tej cov engineering yas; nplaim retardant khoom; siv los hloov F11 thiab F12 siv rau synthesis ntawm cov khoom; cov khoom siv tshuaj zoo.
Ntim, cia thiab thauj
Galvanized steel, dub steel nruas lossis tank ntim ntim ntim ntim ntim ntawm dichloromethane, 80%, tuaj yeem muab kev tiv thaiv nitrogen rau cov neeg siv khoom tshwj xeeb. Kev khaws cia yuav tsum tau muab cia rau hauv qhov chaw txias thiab qhuav, lub tsev khaws khoom yuav tsum tau tso cua kom tsis txhob sib cuag nrog cov pa oxygen lossis oxides siab, kom tsis txhob sib cuag nrog dej txhawm rau tiv thaiv hydrolysis. Kev thauj mus los yuav tsum ua raws li cov kev cai ntawm Tuam Txhab Tuam Txhab Tuam Txhab ntawm Tuam Tshoj hais txog kev thauj cov tshuaj txaus ntshai los ntawm txoj kev loj thiab kev tsheb ciav hlau.
Kev noj qab haus huv thiab kev nyab xeeb
Sichloromethane nyob rau hauv huab cua tawg txwv: 8.1 ~ 17.2%, belongs rau combustible chemicals. High concentration, lub sij hawm ntev raug yooj yim ua rau kiv taub hau, tsaug zog, xeev siab, tinnitus los yog o ntawm ceg ceg, txav mus rau cov huab cua ntshiab, cov tsos mob rov qab sai sai, yuav tsis ua rau kev puas tsuaj mus ntev. Txau rau hauv lub qhov muag ua rau mob thiab khaus khaus, kev sib cuag nrog daim tawv nqaij mus ntev tuaj yeem ua rau dermatitis.
