Khoom Taw Qhia
Cov tshuaj nplua nuj yog cov kws tshaj lij Tuam Tshoj Dichhlorompethane ua nyob rau hauv Suav teb, uas tau koom nrog cov organic tshuaj rau 10 xyoo. Kev muab cov qauv pub dawb, peb sov siab txais tos koj mus yuav cov khoom zoo tsis muaj tshuaj lom neeg thiab tus nqi qis nrog peb.
Khoom Qhia Qhia
Cov Qauv Molecular: Ch2Cl2
Molecular hnyav: 84.93
Lub cev thiab tshuaj lom neeg: tsis muaj peev xwm tawg paj tshab volatile kua, zoo ib yam li ether thiab qab zib.
Txheeb ze ntom: d4201.326kg / l.
Hnneg Tes Taw Tes: 40.4 DEG C.
Melting taw tes: -96.7 degrees, lub ignition point ntawm 615 deg soluble hauv dej, soluble hauv ethanol, ethyl ethanol, lom ether, toxic stimulation. Dichhloromethane thiab dej hydrolysis kev tawm tsam, dihlorometeShane muaj cov kev lag luam stabilizer, txhawm rau tiv thaiv hydrolysis. Dichhloromethane thiab siab siab oxygen yuav muab cov hmoov tawg, yog feem ntau siv hauv kev lag luam ntawm cov tshuaj lom tsawg, tsis muaj kuab lom thiab kub npau taws.
Lub hom phiaj
Rau cov kuab tshuaj tsis yog kuab: hlau ntxuav, pleev xim tshem tawm, siv cov neeg saib xyuas, peb cellulose acetting; Zaj duab xis, aerosol, tshuaj tua kab mob thiab vitamins hauv kev tsim cov kuab tshuaj; Foaming tus neeg sawv cev rau ua npuas ncauj rau kev tsim cov khoom lag luam engineering; nplaim taws retardant khoom; siv los hloov F11 thiab F12 siv rau cov khoom siv hluav taws xob; Cov khoom siv tshuaj lom zoo.
Ntim, cia thiab tsheb thauj mus los
Galvanized steel, Dub Hlau Nruas lossis Tank Ntim Ntim Ntim Ntim Thawv Dichhloromethane, 80%, tuaj yeem muab kev tiv thaiv nitrogen rau cov neeg siv tshwj xeeb. Cia yuav tsum tau muab cia rau hauv qhov chaw txias thiab qhuav, lub tsev rau khoom kom tsis txhob muaj pa lossis oxides, kom tsis txhob sib cuag nrog cov dej hauv cov ntshav. Kev thauj yuav tsum ua raws li cov kev cai ntawm cov neeg koom pheej ntawm Tuam Tshoj hais txog kev thauj khoom ntawm cov tshuaj muaj kuab lom los ntawm kev loj thiab kev tsheb nqaj hlau.
Kev Noj Qab Haus Huv thiab Kev Nyab Xeeb
Sichhlorometeane nyob rau hauv cov huab cua tawg txwv: 8.1 ~ 17.2%, belongs kom cov tshuaj sib cais. Kev siab, ntev ntev kis tau yooj yim rau kiv taub hau, tsaug zog, tinning lossis loog lossis mob siab rau cov huab cua tshiab, yuav tsis ua rau muaj kev puas tsuaj ntev. Txaws ua rau lub qhov muag ua rau mob thiab voos, sib chwv nrog daim tawv nqaij tuaj yeem ua rau muaj mob dermatitis.
