I-1,2-Dichloroethane: Ikhemikhali yemizi-mveliso enokusebenziseka ngeendlela ezininzi
IiNdawo eziPhambili zeSicelo
Kwishishini leekhemikhali, ukusetyenziswa okuphambili kwe-1,2-dichloroethane kukusetyenziswa njengezinto eziluhlaza ukuvelisa i-vinyl chloride. I-vinyl chloride yi-monomer ebalulekileyo esetyenziselwa ukuvelisa i-polyvinyl chloride (PVC), iplastiki esetyenziswa kakhulu ekwakheni, ekufakeni imibhobho, ekugqumeni iintambo, nakwizinto zokupakisha. Ukongeza, i-1,2-dichloroethane inokuguqulwa ibe yi-acetylene ngokusebenzisa i-dehydrochlorination. I-acetylene yinto ebalulekileyo yokwenziwa kwezinto eziphilayo, esetyenziswa ekuveliseni iimveliso ezahlukeneyo zeekhemikhali ezifana ne-acetaldehyde, i-acetic acid, kunye nerabha ye-chloroprene.
Kwicandelo le-solvent, i-1,2-dichloroethane sisinyibilikisi esisebenzayo se-organic esikwaziyo ukunyibilikisa uluhlu olubanzi lwee-organic compounds kunye nee-polymers. Isetyenziswa kakhulu ekucoceni nasekususeni amafutha kumphezulu wesinyithi, ingakumbi kumashishini e-elektroniki kunye nokulungisa oomatshini. Ukongeza, i-1,2-dichloroethane isetyenziselwa ukususa ipeyinti kunye ne-coating, kunye nokucoca izixhobo zokuprinta kushishino lokuprinta.
Kwimizi-mveliso yezibulali-zinambuzane neziqholo, i-1,2-dichloroethane isetyenziswa njengesithako esiphakathi. Ingasetyenziselwa ukuvelisa izibulali-zinambuzane ezahlukeneyo, ezifana nezibulali-zinambuzane kunye nezibulali-zinambuzane, ezisetyenziswa kakhulu kwezolimo. Ukongeza, i-1,2-dichloroethane ingasetyenziselwa ukuvelisa iziqholo kunye nezinongo, ezisetyenziswa kakhulu kumashishini okutya kunye nezithambiso.
Kwindlela yokunyanga amanzi, izinto eziphuma kwi-1,2-dichloroethane, ezifana ne-chlorine polyethylene, zisetyenziselwa ukwenza izinto ezingangeni manzi nezimelana nokugqwala. Ezi zinto zisetyenziswa kakhulu kunyango lokuthintela ukugqwala kwamanzi kwizakhiwo nakwizixhobo zoshishino, nto leyo ethintela ngempumelelo ukungena kwamanzi nokugqwala.
Nangona isetyenziswa kwiindawo ezininzi zoshishino, i-1,2-dichloroethane inobungozi, kwaye ukusetyenziswa kwayo kufuna ukuthotyelwa ngokungqongqo kwimigaqo yokhuseleko. Imveliso yemizi-mveliso idla ngokusebenzisa iinkqubo ezivaliweyo ukunciphisa ukuguquguquka kwayo kwaye ixhotyiswe ngeenkqubo ezisebenzayo zokungenisa umoya kunye neenkqubo zonyango lokukhupha umoya ukuze kukhuselwe impilo yabasebenzi kunye nokhuseleko lokusingqongileyo. Ngolwazi olukhulayo ngokusingqongileyo, inkqubo yokuvelisa i-1,2-dichloroethane ikwaphuculwa ukuze kuncitshiswe impembelelo yayo kokusingqongileyo.
