DCM waa dareere si weyn loo isticmaalo. Waxa intaa dheer in synthesis organic, DCM sidoo kale waxaa si ballaaran loo isticmaalaa sida dareere ah ee wax soo saarka ee film acetate cellulose, sawir triacetate cellulose, batroolka dewaxing, aerosol iyo antibiyootiga, vitamins, xeryahooda steroidal ee wax soo saarka buugaagta kiimikada, iyo sidoo kale rinjiga dusha biraha. nadiifinta xaalufinta iyo ka saarida filimada. Intaa waxaa dheer, waxaa loo isticmaalaa sida wakiilka xumbo-saare ee wax-soo-saarka xumbada urethane polyether iyo sida wakiilka xumbo ee loogu talagalay balaastigga xumbo polysulfone.
1. Loo isticmaalo sida dareere aad u fiican soosaarka dareeraha organic, wakiilka kala qaybinta, vesicant, saabuunta, iyo neef-qabatinka, degease, qaboojiyaha iwm.
2. Waxaa loo istcimaalaa falcelinta dhexdhexaadinta warshadaha dawooyinka sida diyaarinta ampicillin, ampicillin iyo cephalosporin, iwm.
3. Loo isticmaalo soosaar ahaan si ay u nadiifiso qaxwada iyo shaaha, u diyaariso wax laga soosaaray hops iyo dhadhanka kale
4. Waxaa loo isticmaalaa caanaha rinjiga iyo nadiifiyaha
5. Loo isticmaalo warshadaha elektiroonigga ah. ugu weyn oo loo isticmaalo sidii nadiifinta iyo walaxda wasakhaynta.
