Lub hom phiaj ntawm dichloromethane:
Dichloromethane muaj peev xwm ua kom tiav thiab tsis tshua muaj tshuaj lom;nws yog siv ntau rau kev tsim cov yeeb yaj kiab zoo thiab Makrolon;qhov seem yog siv rau cov xim hnyav, cov hlau degreasing tus neeg sawv cev, cov pa luam yeeb thiab cov roj txhaj tshuaj, polyurethane tshuab tshuab, tso tawm tus neeg saib xyuas thiab cov xim tshem tawm;
Dichloromethane yog cov kua tsis muaj xim.Nws yog siv los ua cov tshuaj tiv thaiv nruab nrab hauv kev lag luam muag tshuaj thiab siv rau kev npaj ntawm penbritin, carbenicillin, cephalosporin, thiab lwm yam, rau cov kuab tshuaj los ua cov zaj duab xis, roj dewaxing hnyav, aerosol propellant, organic synthesis extraction agent, polyurethane thiab lwm yam foaming agent thiab hlau nqus tsev vacuum thaum tsim cov yas foamed.
