1,2-Dichloroethane: Musamu Uubelesyegwa Mumakwebo
Zibeela Zipati Zyakubelesya
Mumakwebo aamakemikalu, kubelesya kutaanzi kwa 1,2-dichloroethane nkubelesya kupanga vinyl chloride. Vinyl chloride nchintu chipati chibelesyegwa kupanga polyvinyl chloride (PVC), pulasitiki iibelesyegwa kapati mukuyaka, mumapayipi, mukukwabilila ntambo, amuzibelesyo zyakubikkila zintu. Kuyungizya waawo, 1,2-dichloroethane ilakonzya kusandulwa kuba acetylene kwiinda mukugwisya maanzi. Acetylene nchintu chiyandikana loko mukupanga zintu zipona, chibelesyegwa mukupanga misamu isiyene-siyene mbuli acetaldehyde, acetic acid, antoomwe a chloroprene rubber.
Muchibaka chakusanzya, 1,2-dichloroethane nchintu chibotu loko chikonzya kunyonyoona zintu zyiingi zipona antoomwe ama polymer. Chiindi chiingi chibelesegwa kusalazya akugwisya mafuta atala aabutale, kampatila mumakkampani aapanga minchina. Kuyungizya waawo, 1,2-dichloroethane ilabelesyegwa kugwisya penti akuvwumba, antoomwe akusalazya zibelesyo zyakudinda mumakkampani aakudinda.
Mumakwebo aamisamu iijaya tuzunda alimwi atununkilizyo, 1,2-dichloroethane ilabelesyegwa mbuli chintu chili akati. ilakonzya kubelesegwa kupanga misamu iijaya tuzunda, mbuli misamu iijaya tuzunda, eeyo iibelesyegwa kapati mubulimi. Kuyungizya waawo, 1,2-dichloroethane ilakonzya kubelesegwa kupanga tununkilizyo azyakununkilila, zibelesyegwa kapati mumakwebo aazyakulya azyakulisakatizya.
Mukusalazya maanzi, zintu zizwa ku 1,2-dichloroethane, mbuli chlorinated polyethylene, zilabelesyegwa kupanga zintu zitanjili maanzi alimwi zitanyonyooki. Eezyi zintu zibelesyegwa kapati mukulesya maanzi mumaanda amuzibelesyo zyamafakitali, ikukwabilila maanzi kuti atanjili akubola.
Nikuba kuti ilabelesyegwa munzila zyiingi mumafakitali, 1,2-dichloroethane ilakola, mpawo kubelesya kwayo kuyandika kutobela milawu yakukwabilila. Kupanga zintu mumafakitali kanjikanji kubelesya nzila zijalidwe kuchitila kuti kutabi kuzungaana kwawo mpawo kuli nzila zigwasya zyakunjizya muya akugwisya muya kutegwa kutabi buumi bwababelesi akukwabililwa kwabusena. Alubo luzibo lwazyintu zizingulukide, nzila yakupanga 1,2-dichloroethane ayalo ilasumpulwa kuchitila kuti ichite ntenda kuzingulukide.

Mubufwaafwi
Muchi chifwiifwi, 1,2-dichloroethane, mbuli chintu chibelesegwa munzila zyiingi, chili achuuno chipati mumakwebo. Tachigwasyi buyo kupanga misamu iiyandika pesi alimwi chigwasyilizya kuyaambele kwamakwebo aamazubaano. Kakuli kuyaambele kwabusongo, nzila zyakubelesya 1,2-dichloroethane ziyooba zipati.
