Kev siv
Ib tug ntawm cov yam ntxwv tseem ceeb ntawm dichloromethane yog nws versatility. Nws yog dav siv los ua cov kuab tshuaj, extractant thiab mutagen, ua rau nws nrov hauv cov chaw kuaj thiab cov chaw tshawb fawb. Nws solubility nyob rau hauv ethanol thiab ether thiab nws tsis-flammable ua rau nws muaj kev nyab xeeb dua lwm yam flammable tshuaj xws li roj av ether. Cov cuab yeej no ua rau dichloromethane yog ib qho kev xaiv nrov rau cov nplej fumigation thiab cov tub yees hauv cov tub yees txias thiab cov khoom siv cua txias. Nws lub peev xwm los hloov cov tshuaj phem thaum tswj kev ua haujlwm siab ua rau nws yog thawj qhov kev xaiv hauv kev lag luam kev nyab xeeb-tseem ceeb.
Tsis tas li ntawd, methylene chloride plays lub luag haujlwm tseem ceeb hauv kev lag luam hluav taws xob. Nws zoo heev tu thiab degreasing cov khoom ua rau nws zoo tagnrho rau kev tu kom zoo hauv kev tsim khoom siv hluav taws xob. Los ntawm cov kab hluav taws xob tsis zoo rau cov khoom siv me me, methylene chloride ua kom cov txheej txheem ntxuav kom huv si. Tsis tas li ntawd, nws yog ib qho tseem ceeb hauv nruab nrab ntawm cov organic synthesis, muaj peev xwm tsim tau ntau cov khoom muaj txiaj ntsig zoo. Nws muaj nyob rau hauv ntau yam industries qhia txog nws versatility thiab indispensability.
Ntxiv nrog rau kev siv dav dav, dichloromethane kuj muaj qhov ua tau zoo tshaj plaws raws li kev kho hniav hauv zos tshuaj loog, tshuaj tua hluav taws, thiab cov xim hlau xim ntxuav thiab degreasing stripping tus neeg saib xyuas. Nws lub peev xwm los muab tshuaj loog thiab tua hluav taws underscores nws cov khoom tshwj xeeb. Tsis tas li ntawd, nws muaj txiaj ntsig zoo tshem tawm cov txheej txheem tsis xav tau thiab cov kab mob tsis zoo los ntawm cov chaw hlau, ua kom lub ntsej muag zoo rau kev pleev xim thiab ua haujlwm ntxiv.
Hauv kev xaus, dichloromethane yog ntau yam sib xyaw nrog cov khoom zoo heev. Nws lub peev xwm los hloov cov khoom phom sij thaum tswj kev ua haujlwm zoo ua rau nws muaj txiaj ntsig zoo thoob plaws ntau qhov kev lag luam. Txawm hais tias siv hauv kev ua qoob loo, kev tsim khoom siv hluav taws xob lossis kev siv kho hniav, methylene chloride tau ua pov thawj tias yog qhov kev xaiv zoo. Nrog nws cov kev siv ntau yam thiab cov khoom zoo kawg nkaus, cov organic compound no tau npaj los hloov pauv ntau yam kev lag luam thoob plaws ntiaj teb. Kawm paub lub zog ntawm methylene chloride thiab qhib qhov muaj peev xwm tshiab hauv koj cov khoom siv tes ua.
