Kev Taw Qhia Txog Khoom
Rich Chemical yog ib lub tuam txhab kev lag luam hauv Suav teb uas muab cov tshuaj dichloromethane rau kev lag luam, uas tau koom nrog cov tshuaj lom neeg rau 10 xyoo. Peb muab cov qauv dawb, peb zoo siab tos txais koj kom yuav cov tshuaj CAS No. zoo nrog kev ntshiab siab thiab tus nqi qis nrog peb.
Cov ntsiab lus ntawm cov khoom
Cov mis mos molecular: CH2CL2
Qhov hnyav molecular: 84.93
Cov khoom siv lub cev thiab tshuaj lom neeg: tsis muaj xim pob tshab volatile kua, zoo ib yam li tsw ntawm ether thiab qab zib.
Qhov ceev sib piv: D4201.326Kg/L.
Kub taw tes: 40.4 ℃.
Qhov taw tes yaj: -96.7 degrees, qhov taw tes hluav taws xob ntawm 615 DEG C. Me ntsis yaj hauv dej, yaj hauv ethanol, ethyl ether, lom, tshuaj narcotic stimulation. Dichloromethane thiab dej hydrolysis reaction, dichloromethane muaj stabilizer lag luam, los tiv thaiv hydrolysis. Dichloromethane thiab cov pa oxygen concentration siab yuav tsim cov khoom sib xyaw tawg, tab sis tsis yooj yim hlawv, feem ntau siv hauv kev lag luam ntawm cov tshuaj lom tsawg, cov kuab tshuaj tsis yooj yim hlawv thiab qhov kub tsawg.
Lub Hom Phiaj
Rau cov kuab tshuaj uas tsis yooj yim hlawv: kev ntxuav hlau, kev tshem tawm xim, tus neeg sawv cev tshem cov roj hlau, peb cov kuab tshuaj cellulose acetate; zaj duab xis, aerosol, tshuaj tua kab mob thiab cov vitamins hauv kev tsim cov kuab tshuaj; tus neeg sawv cev ua npuas ncauj rau kev ua npuas ncauj rau kev tsim cov yas engineering; cov khoom hluav taws kub; siv los hloov F11 thiab F12 siv rau kev tsim cov khoom; cov khoom siv tshuaj zoo.
Ntim, khaws cia thiab thauj mus los
Cov hlau galvanized, cov hlau dub nruas lossis lub thawv ntim khoom kaw uas muaj dichloromethane, 80%, tuaj yeem muab kev tiv thaiv nitrogen rau cov neeg siv uas muaj kev xav tau tshwj xeeb. Kev khaws cia yuav tsum khaws cia rau hauv qhov chaw txias thiab qhuav, lub tsev rau khoom yuav tsum tau cua nkag kom tsis txhob muaj kev sib cuag nrog cov pa oxygen lossis oxides ntau, kom tsis txhob muaj kev sib cuag nrog dej kom tiv thaiv kev hydrolysis. Kev thauj mus los yuav tsum ua raws li cov kev cai ntawm Lub Koom Haum Neeg Sawv Cev ntawm Tuam Tshoj txog kev thauj cov tshuaj lom neeg txaus ntshai los ntawm txoj kev loj thiab txoj 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%, yog cov tshuaj uas yooj yim hlawv. Kev sib xyaw ua ke ntau, kev raug ntev ntev yooj yim ua rau kiv taub hau, qaug zog, xeev siab, tinnitus lossis loog ntawm ceg, txav mus rau huab cua ntshiab, cov tsos mob rov qab sai sai, yuav tsis ua rau puas tsuaj ntev. Splash rau hauv qhov muag ua rau mob thiab khaus, kev sib cuag ntev nrog daim tawv nqaij tuaj yeem ua rau mob dermatitis.
