Usage
Imwe yemhando huru yedichloromethane ndeyekuita kwayo kwakasiyana-siyana. Inoshandiswa zvakanyanya se solvent, extractant uye mutagen, ichiita kuti ive yakakurumbira mumarabhoritari uye nzvimbo dzekutsvagisa. Kunyungudika kwayo mu ethanol uye ether uye kusapisa kwayo kunoita kuti ive imwe nzira yakachengeteka kune zvinhu zvinopisa zvakadai se petroleum ether. Ichi chivakwa chinoita kuti dichloromethane ive sarudzo yakakurumbira yezviyo fumigation uye firiji mune yakaderera-kudzvanywa mafiriji uye mhepo-inogadzirisa midziyo. Kugona kwayo kutsiva makemikari ane njodzi uku uchichengetedza kuita kwepamusoro kunoita kuti ive sarudzo yekutanga mumaindasitiri akakosha akachengeteka.
Uyezve, methylene chloride inoita basa rakakosha muindasitiri yemagetsi. Kucheneswa kwayo kwakanakisa uye kudzikisira zvimiro kunoita kuti ive yakakodzera kucheneswa kwakanaka kunodiwa mukugadzira zvemagetsi. Kubva pamabhodhi ematunhu akaomarara kusvika kune akatetepa, methylene chloride inova nechokwadi chekuchenesa, kusina gwapa. Uye zvakare, chinhu chakakosha chepakati mune organic synthesis, inokwanisa kuburitsa huwandu hukuru hwemakomisheni akakosha. Kuvapo kwayo mumaindasitiri akasiyana-siyana kunoratidza kuenderana kwayo uye kusakosha.
Pamusoro pekushandiswa zvakanyanya, dichloromethane zvakare ine hunyanzvi hwekuita senge mazino emuno anesthetic, anodzima moto mumiriri, uye simbi pamusoro pependi yekuchenesa uye degreasing stripping agent. Kugona kwayo kupa anesthesia uye kudzvanywa kwemoto kunosimbisa hunhu hwayo hwakasiyana. Pamusoro pezvo, zvinonyatso bvisa machira asingadiwe uye zvinosvibisa kubva kune simbi, kuve nechokwadi cheyakanaka canvas yekupenda uye kuenderera mberi nekugadzirisa.
Mukupedzisa, dichloromethane isanganiswa inosiyana-siyana ine yakanakisa zvivakwa. Kugona kwayo kutsiva zvinhu zvine njodzi uku ichichengetedza kuita kwakanaka kunoita kuti ive chinhu chakakosha mumaindasitiri mazhinji. Ingave ichishandiswa mukupisa zviyo, kugadzira zvemagetsi kana kushandisa mazino, methylene chloride yakaratidza kuve sarudzo yakavimbika. Nehupamhi hwemashandisirwo ayo uye zvinoshamisa zvivakwa, iyi organic compound yakagadzirira kushandura maindasitiri mazhinji pasi rose. Sangana nesimba remethylene chloride uye uvhure mikana mitsva muhunyanzvi hwako.
