1,2-Dichloroethane: Mankhwala Ogwiritsidwa Ntchito Mosiyanasiyana M'mafakitale
Minda Yaikulu Yogwiritsira Ntchito
Mu makampani opanga mankhwala, ntchito yaikulu ya 1,2-dichloroethane ndi kupanga vinyl chloride. Vinyl chloride ndi monomer yofunika kwambiri yomwe imagwiritsidwa ntchito popanga polyvinyl chloride (PVC), pulasitiki yomwe imagwiritsidwa ntchito kwambiri popanga, kupanga mapaipi, kutchinjiriza mawaya, ndi zinthu zomangira. Kuphatikiza apo, 1,2-dichloroethane imatha kusinthidwa kukhala acetylene kudzera mu dehydrochlorination. Acetylene ndi chinthu chofunikira kwambiri popanga zinthu zachilengedwe, chomwe chimagwiritsidwa ntchito popanga mankhwala osiyanasiyana monga acetaldehyde, acetic acid, ndi chloroprene rabara.
Mu gawo la zosungunulira, 1,2-dichloroethane ndi chosungunulira chachilengedwe chogwira ntchito bwino chomwe chingathe kusungunula mitundu yosiyanasiyana ya mankhwala ndi ma polima achilengedwe. Chimagwiritsidwa ntchito kwambiri poyeretsa ndi kuchotsa mafuta pamwamba pa zitsulo, makamaka m'mafakitale a zamagetsi ndi makina. Kuphatikiza apo, 1,2-dichloroethane imagwiritsidwa ntchito pochotsa utoto ndi utoto, komanso poyeretsa zida zosindikizira m'makampani osindikizira.
Mu mafakitale ophera tizilombo ndi zonunkhira, 1,2-dichloroethane imagwiritsidwa ntchito ngati chowonjezera. Ingagwiritsidwe ntchito popanga mankhwala osiyanasiyana ophera tizilombo, monga mankhwala ophera tizilombo ndi ophera tizilombo, omwe amagwiritsidwa ntchito kwambiri muulimi. Kuphatikiza apo, 1,2-dichloroethane ingagwiritsidwe ntchito popanga zonunkhira ndi zokometsera, zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale azakudya ndi zodzoladzola.
Pochiza madzi, zinthu zochokera ku 1,2-dichloroethane, monga polyethylene yokhala ndi chlorine, zimagwiritsidwa ntchito popanga zinthu zosalowa madzi komanso zosawononga dzimbiri. Zinthuzi zimagwiritsidwa ntchito kwambiri pochiza madzi m'nyumba ndi m'mafakitale, zomwe zimathandiza kuti madzi asalowe komanso asawonongeke.
Ngakhale kuti imagwiritsidwa ntchito m'mafakitale osiyanasiyana, 1,2-dichloroethane ndi poizoni, ndipo kugwiritsidwa ntchito kwake kumafuna kutsatira malamulo achitetezo. Kupanga mafakitale nthawi zambiri kumagwiritsa ntchito makina otsekedwa kuti achepetse kusinthasintha kwake ndipo kumakhala ndi njira zopumira bwino komanso zotsukira utsi kuti ziteteze thanzi la ogwira ntchito komanso chitetezo cha chilengedwe. Chifukwa cha kuchuluka kwa chidziwitso cha chilengedwe, njira yopangira 1,2-dichloroethane ikukonzedwanso kuti ichepetse kuwononga chilengedwe.

Powombetsa mkota
Mwachidule, 1,2-dichloroethane, monga mankhwala opangidwa ndi zinthu zachilengedwe, ili ndi udindo wofunikira m'makampani. Sikuti imangothandiza kupanga mankhwala osiyanasiyana ofunikira komanso imathandizira chitukuko cha mafakitale amakono. Ndi kupita patsogolo kwaukadaulo kosalekeza, mwayi wogwiritsa ntchito 1,2-dichloroethane udzakhala waukulu kwambiri.
