Khoom Description
DCM methylene chloride (dichloromethane, hu ua DCM, CAS RN 75-09-2) muaj qhov zoo ntawm kev muaj zog solubility thiab tsis muaj tshuaj lom. DCM methylene chloride yog siv rau hauv tub yees, tshuaj, tshuaj tua kab, tshuaj nplaum, polyurethane foaming, tu, thiab lithium roj teeb cais. , zaub mov additives thiab lwm yam teb. Muaj ob txoj kev tsim khoom rau methylene chloride: natural gas chlorination thiab methyl chloride chlorination.
Dichloromethane methylene chloride muaj kev nyab xeeb thiab yog ib qho ntawm plaub hom chlorinated methane. CH2Cl2 dichlorodihydrogen muaj cov ntxhiab tsw me ntsis. Nws muaj qhov siab olfactory pib ntawm 522 mg / m3 thiab tsis tshua khaus. Nws muaj qhov melting point ntawm -97 degree, qhov kub ntawm 39.8 degree, thiab saturated vapor siab ntawm 46.5kPa (20 degree). Dichloromethane yog non-flammable, nrog rau qhov kub thiab txias ntawm 556 degree thiab tawg txwv ntawm 14 ~ 22%. Nws yuav tsim cov khoom tawg thaum sib xyaw nrog cov pa oxygen siab. Nws yog ib qho uas tsis yog-flammable low-boiling point solvent nyob rau hauv ib txwm siv tej yam kev mob thiab feem ntau yog siv los hloov cov roj av flammable. Ether, diethyl ether, thiab lwm yam muaj zoo solubility nyob rau hauv ntau resins, paraffin waxes thiab rog. Lawv yog ib qho ntawm cov kuab tshuaj uas tsis muaj qhov kub thiab txias uas tsis muaj toxicity thiab zoo non-flammable nyob rau hauv industrial solvents.
Main siv:
Methylene chloride yog siv los ua xim hnyav, hlau degreasing, aerosol propellant, polyurethane foaming tus neeg saib xyuas, pwm tso tus neeg sawv cev, xim tshem tawm thiab hauv kev tsim cov yeeb yaj kiab thiab polycarbonate. Nws yog ib qho hnyav heev. Nws kuj yog siv rau lub tub yees ntawm cov xovxwm tub yees thiab cua txias.
