1,2-Dichloroethane: Kemikari Inoshandiswa Mumaindasitiri Inoshandiswa Pakuchinja-chinja
Minda mikuru yekushandisa
Muindasitiri yemakemikari, kushandiswa kukuru kwe1,2-dichloroethane kunoshandiswa kugadzira vinyl chloride. Vinyl chloride imonomer inokosha inoshandiswa kugadzira polyvinyl chloride (PVC), ipurasitiki inoshandiswa zvakanyanya mukuvaka, kupinza mapaipi, kuputira tambo, uye kurongedza. Pamusoro pezvo, 1,2-dichloroethane inogona kushandurwa kuita acetylene kuburikidza ne dehydrochlorination. Acetylene chinhu chakakosha chekugadzira organic, chinoshandiswa mukugadzira zvigadzirwa zvakasiyana-siyana zvemakemikari zvakaita seacetaldehyde, acetic acid, uye chloroprene rabha.
Muchikamu chezvekunyungudutsa, 1,2-dichloroethane chinhu chinoshanda zvakanaka chezvekunyungudutsa chinogona kunyungudutsa mhando dzakasiyana dzezvekunyungudutsa uye mapolymer. Chinowanzoshandiswa kuchenesa nekubvisa mafuta pamusoro pesimbi, kunyanya mumaindasitiri ezvemagetsi nekugadzira michina. Pamusoro pezvo, 1,2-dichloroethane inoshandiswa kubvisa pendi nependi, pamwe nekuchenesa michina yekudhinda muindasitiri yekudhinda.
Mumaindasitiri emishonga inouraya zvipembenene nezvinonhuwira, 1,2-dichloroethane inoshandiswa senzira yepakati. Inogona kushandiswa kugadzira mishonga yakasiyana-siyana yezvipembenene, yakadai semishonga inouraya zvipembenene nezvipembenene, iyo inoshandiswa zvakanyanya mukurima. Pamusoro pezvo, 1,2-dichloroethane inogona kushandiswa kugadzira zvinonhuwira nezvinonhuwira, zvinoshandiswa zvakanyanya mumaindasitiri ezvekudya nezvinonhuwira.
Mukurapa nemvura, zvinhu zvinobva mu1,2-dichloroethane, zvakaita se chlorinated polyethylene, zvinoshandiswa kugadzira zvinhu zvisingapindi mvura uye zvisingapindi ngura. Zvinhu izvi zvinoshandiswa zvakanyanya mukurapa mvura muzvivakwa nemidziyo yemumaindasitiri, zvichidzivirira kupinda kwemvura uye ngura.
Pasinei nekushandiswa kwayo kwakasiyana-siyana mumaindasitiri, 1,2-dichloroethane ine chepfu, uye kushandiswa kwayo kunoda kunyatsotevedzera mitemo yekuchengetedza. Kugadzirwa kwemaindasitiri kunowanzo shandisa masisitimu akavharwa kuderedza kusagadzikana kwayo uye ine masisitimu anoshanda ekufema nekurapa utsi hwemhepo kudzivirira hutano hwevashandi nekuchengetedzeka kwezvakatipoteredza. Nekuwedzera kweruzivo rwezvakatipoteredza, maitiro ekugadzira 1,2-dichloroethane ari kugadziriswawo kuti aderedze kukanganisa kwayo nharaunda.

Muchidimbu
Muchidimbu, 1,2-dichloroethane, sezvinhu zvinogadzirwa nemakemikari eorganic, ine chinzvimbo chakakosha muindasitiri. Haingogonese chete kugadzirwa kwemakemikari akasiyana-siyana akakosha asiwo inotsigira kukura kweindasitiri yemazuva ano. Nekufambira mberi kwetekinoroji, mikana yekushandisa 1,2-dichloroethane ichave yakakura zvakanyanya.
