Iipropati zeMichiza:

I-Dichloromethane, i-organic compound kunye ne-chemical formula CH2Cl2, ilulwelo olungenambala olucacileyo kunye ne-ether-like ivumba elicaphukisayo. Inyibilika kancinane emanzini, inyibilika kwi-ethanol kunye ne-ether, yindawo yokubila ephantsi engatshiyo phantsi kweemeko eziqhelekileyo zokusetyenziswa, kwaye umphunga wayo uye uxinaniswe kakhulu kubushushu obuphezulu bomoya phambi kokuvelisa umxube wegesi otshayo, kwaye uhlala usetyenziswa. ukubuyisela i-ether ye-petroleum enokutsha, i-ether, njl.

Isicelo:

Ukusetyenziswa kweNdlu
Ikhompawundi isetyenziswa ekuhlaziyeni ibhafu. I-Dichloromethane isetyenziswa kakhulu kwimizi-mveliso kwimveliso yamayeza, ii-strippers, kunye nezinyibilikisi zenkqubo.
Usetyenziso lwemizi-mveliso kunye nemveliso
I-DCM sisinyibilikisi esifumaneka kwi-varnish kunye ne-strippers yepeyinti, ehlala isetyenziselwa ukususa ivanishi okanye iipeyinti zepeyinti kwiindawo ezahlukeneyo. Njenge-solvent kwishishini lamachiza, i-DCM isetyenziselwa ukulungiswa kwe-cephalosporin kunye ne-ampicillin.
Ukwenziwa koKutya kunye neziselo
Iyasetyenziswa nasekuveliseni isiselo kunye nokwenziwa kokutya njengesinyibilikisi esikhuphayo. Umzekelo, i-DCM ingasetyenziselwa ukuthobisa iimbotyi zekofu ezingagcadwanga kunye namagqabi eti. Ikhompawundi ikwasetyenziswa ekudaleni ihops extract yebhiya, iziselo kunye nezinye iziqholo ekutyeni, nasekulungiseni izinongo.
Ishishini lezoThutho
I-DCM iqhele ukusetyenziselwa ukucolwa kwentsimbi kunye nemigangatho, njengezixhobo zikaloliwe kunye neengoma kunye nezinto zenqwelomoya. Isenokusetyenziswa ekudambiseni igrisi kunye neemveliso zokuthambisa ezisetyenziswa kwiimveliso zeemoto, umzekelo, ukususwa kwegasket kunye nokulungiselela iindawo zentsimbi zegasket entsha.
Iingcali kwiimoto zihlala zisebenzisa inkqubo yokunciphisa idichloromethane yomphunga ukuya ekususeni igrisi kunye neeoyile kwiindawo zemoto zetransistor yemoto, iindibano zesphekepheke, izinto zenqwelomoya, kunye neenjini zedizili. Namhlanje, iingcali ziyakwazi ukucoca ngokukhuselekileyo nangokukhawuleza iinkqubo zothutho zisebenzisa iindlela zokuthoba ezixhomekeke kwi-methylene chloride.
Ishishini lezonyango
I-Dichloromethane isetyenziswa kwiilabhoratri ekutsalweni kweekhemikhali ekutyeni okanye kwizityalo kumayeza afana ne-antibiotics, i-steroids, kunye neevithamini. Ukongeza, izixhobo zonyango zinokucocwa ngokufanelekileyo nangokukhawuleza kusetyenziswa izicoci ze-dichloromethane ngelixa zithintela umonakalo kwiindawo ezingeva lubushushu kunye neengxaki zokubola.
Iifilimu zeeFoto
I-Methylene chloride isetyenziswe njenge-solvent kwimveliso ye-cellulose triacetate (CTA), esetyenziswa ekudalweni kweefilimu ezikhuselekileyo kwiifoto. Xa inyibilika kwi-DCM, i-CTA iqala ukujika ibe ngumphunga njengoko i-fiber ye-acetate ihlala ngasemva.
Ishishini le-elektroniki
I-Methylene chloride isetyenziselwa ukuveliswa kweebhodi zeesekethe eziprintiweyo kwishishini lombane. I-DCM isetyenziselwa ukuthoba umphezulu wefoyile ye-substrate phambi kokuba umaleko wefotoresist wongezwe ebhodini.
