Chemical Properties:

Dichloromethane, ib qho organic compound nrog cov tshuaj formula CH2Cl2, yog cov xim tsis muaj pob tshab uas muaj cov ntxhiab tsw zoo li ether. Me ntsis soluble nyob rau hauv dej, soluble nyob rau hauv ethanol thiab ether, nws yog ib tug uas tsis yog-combustible uas tsis muaj boiling point hnyav nyob rau hauv ib txwm tej yam kev mob ntawm kev siv, thiab nws vapor yuav heev concentrated nyob rau hauv kub kub huab cua ua ntej tsim ib tug weakly combustible sib tov ntawm gases, thiab feem ntau yog siv. los hloov cov roj av flammable ether, ether, thiab lwm yam.

Daim ntawv thov:

Cov Khoom Siv Hauv Tsev
Lub compound yog siv nyob rau hauv da dej refurbishing. Dichloromethane yog siv dav hauv kev tsim cov tshuaj, strippers, thiab cov txheej txheem cov kuab tshuaj.
Kev lag luam thiab kev tsim khoom siv
DCM yog cov kuab tshuaj uas muaj nyob rau hauv cov kua roj vanish thiab xim strippers, uas feem ntau yog siv los tshem tawm cov kua roj vanish lossis xim txheej los ntawm ntau qhov chaw. Raws li cov kuab tshuaj hauv kev lag luam tshuaj, DCM yog siv rau kev npaj ntawm cephalosporin thiab ampicillin.
Khoom noj khoom haus thiab dej haus Manufacturing
Nws kuj tseem siv rau hauv kev tsim dej haus thiab khoom noj khoom haus raws li cov kuab tshuaj extraction. Piv txwv li, DCM tuaj yeem siv los decaffeinate unroasted kas fes taum nrog rau tshuaj yej nplooj. Lub compound kuj yog siv los tsim hops extract rau npias, dej haus thiab lwm yam flavoring rau zaub mov, nrog rau kev ua txuj lom.
Kev lag luam tsheb thauj mus los
DCM feem ntau yog siv rau hauv degreasing ntawm cov hlau qhov chaw thiab qhov chaw, xws li cov khoom siv tsheb ciav hlau thiab cov lem thiab cov khoom siv dav hlau. Nws tseem tuaj yeem siv rau hauv degreasing thiab lubricating cov khoom siv hauv cov khoom siv tsheb, piv txwv li, tshem tawm cov gasket thiab npaj cov khoom hlau rau lub gasket tshiab.
Cov kws tshaj lij hauv tsheb feem ntau siv cov txheej txheem vapor dichloromethane degreasing rau kev tshem tawm cov roj thiab roj los ntawm lub tsheb qhov chaw ntawm lub tsheb transistor, spacecraft assemblies, aircraft Cheebtsam, thiab diesel motors. Niaj hnub no, cov kws tshaj lij muaj peev xwm ua kom muaj kev nyab xeeb thiab huv si sai sai siv cov txheej txheem degreasing uas nyob ntawm methylene chloride.
Kev lag luam kho mob
Dichloromethane yog siv nyob rau hauv lub chaw soj nstuam nyob rau hauv lub extraction ntawm tshuaj los ntawm cov khoom noj los yog cov nroj tsuag rau cov tshuaj xws li tshuaj tua kab mob, steroids, thiab vitamins. Tsis tas li ntawd, cov cuab yeej siv kho mob tuaj yeem ua tau zoo thiab ntxuav sai sai siv cov tshuaj ntxuav dichloromethane thaum tsis txhob muaj kev puas tsuaj rau qhov kub thiab txias thiab teeb meem corrosion.
Cov duab thaij duab
Methylene chloride yog siv los ua ib qho hnyav hauv kev tsim cov cellulose triacetate (CTA), uas yog siv rau hauv kev tsim cov yeeb yaj kiab kev nyab xeeb hauv kev yees duab. Thaum yaj hauv DCM, CTA pib evaporate raws li cov fiber ntau ntawm acetate tseem nyob tom qab.
Kev lag luam hluav taws xob
Methylene chloride yog siv rau hauv kev tsim cov ntawv luam tawm Circuit Court boards hauv kev lag luam hluav taws xob. DCM yog siv los degrease cov ntawv ci ntawm lub substrate ua ntej cov txheej txheem photoresist ntxiv rau lub rooj tsavxwm.
