Isingeniso:
Emhlabeni wamakhemikhali, zimbalwa izinhlanganisela ezithole ukunakwa okungakatrichlorethylene
(I-TCE). Lesi sincibilikisi esinamandla nesiguquguqukayo sithole indawo yaso ezimbonini ezihlukahlukene, kusukela ekususeni insimbi nokuhlanza okomile kuya ezinqubweni zokukhiqiza kanye nezicelo zezokwelapha. Kule bhulogi, sihlose ukunikeza isingeniso esiphelele se-trichlorethylene, ukuhlola ukusetshenziswa kwayo, imiphumela, nokucatshangelwa kwemvelo.
Ukuqonda i-Trichlorethylene:
I-Trichlorethylene, eyaziwa nangokuthi i-TCE noma i-trichloroethene, iwuketshezi olungashi, olungenambala olunephunga elimnandi. Ngokwesakhiwo sayo samakhemikhali, i-TCE iqukethe ama-athomu amathathu e-chlorine axhunywe kwiketango lekhabhoni eliboshwe kabili. Lokhu kwakheka okuyingqayizivele kunikeza i-trichlorethylene izakhiwo zayo ezibalulekile ze-solvency, okuyenza ibe yisinqumo esihle kakhulu ezinhlobonhlobo zezinhlelo zokusebenza.
Izicelo zezimboni:
Okunye okugqame kakhulu ukusetshenziswa kwe-trichlorethylene njenge-ejenti yokwehlisa amafutha ezimbonini zensimbi. I-solvency yayo ephumelelayo ivumela ukuncibilikisa amafutha, amafutha, nokunye ukungcola okuvela ezindaweni zensimbi, ukuqinisekisa ukunamathela okufanele nokuqeda. Ngaphezu kwalokho, i-TCE isetshenziswa kabanzi njenge-ejenti yokuhlanza ku-photolithography, inqubo ebalulekile ekwenziweni kwama-microchips nama-semiconductors.
Ukunyibilika okukhethekile kwe-TCE kuyenza ibe yinketho efanelekile yokuhlanza okomile. Ikhono layo lokuncibilikisa uwoyela, amafutha, namanye amabala, kuhambisana nephuzu layo eliphansi lokubilisa, livumela izindwangu nezindwangu ukuthi zihlanzwe kahle ngaphandle kokudala umonakalo omkhulu.
Izicelo Zokwelashwa:
Ngaphandle kwezicelo zezimboni nezokuhlanza, i-trichlorethylene iye yasetshenziswa emkhakheni wezokwelapha njengesibulala-zinzwa. Uma isetshenziswa ngemithamo elawulwayo negadiwe, i-TCE ingadala isimo sokuquleka, ikwenze ifanelekele izinqubo zokuhlinzwa ezincane. Kodwa-ke, kubalulekile ukuqaphela ukuthi ukusetshenziswa kwe-trichlorethylene njengesibulala-buhlungu kwehlile ngenxa yokwethulwa kwezinye izindlela eziphephile.
Imiphumela Yezempilo Nemvelo:
Nakuba i-trichlorethylene ngokungangabazeki iyikhemikhali ewusizo, ukuchayeka kwayo kubangela izingozi zempilo. Ukuthintana isikhathi eside noma okuphindaphindiwe ne-TCE kungaholela emiphumeleni ehlukahlukene enobuthi, okuhlanganisa ukucindezeleka kwesimiso sezinzwa esimaphakathi, ukulimala kwesibindi, nokungasebenzi kahle kwezinso. Ezimweni ezimbi kakhulu, kungase kubangele nomdlavuza.
Ngaphezu kwalokho, imvelo eguquguqukayo ye-trichlorethylene iyenza ijwayele ukuhwamuka emoyeni, okungaba nomthelela endaweni yasendlini nengaphandle. Ukuchayeka ngokweqile kuntuthu we-TCE kungaholela ekucasukeni kokuphefumula futhi, kwezinye izimo, imiphumela emibi ohlelweni lwenhliziyo nemithambo yegazi. Ngenxa yamandla ayo okungcolisa amanzi angaphansi komhlaba, ukukhululwa kwe-TCE endaweni ezungezile kudinga ukulawulwa okuqinile kanye nezindlela zokulahla ngokucophelela.
Imithethonqubo yezemvelo nokuphatha okuphephile:
Eqaphela izingozi ezingase zibe khona, amazwe amaningana asebenzise imithethonqubo ephathelene nokuphathwa, ukugcinwa, nokusetshenziswa kwe-trichlorethylene. Izimboni ezithembele ku-TCE manje sezidingekile ukuthi zisebenzise izinyathelo zokuphepha, ezifana nokuthwebula kanye nokugaywa kabusha kokukhishwa kwe-TCE, kanye nokusebenzisa izinhlelo ezifanele zokungenisa umoya ukuze kuncishiswe izingozi zokuchayeka.
Isiphetho:
I-Trichlorethylene, enezici zayo zamakhemikhali eziyingqayizivele kanye nohlu olubanzi lwezinhlelo zokusebenza, idlala indima ebalulekile ezimbonini ezihlukahlukene. Nakuba ukusebenza kwayo kungenakuphikwa, kubalulekile ukucabangela ngokucophelela ubungozi obungaba khona bezempilo nemvelo obuhambisana nokusetshenziswa kwayo. Ngokusebenzisa izinyathelo eziqinile zokuphepha nokuthobela imithethonqubo, singaqhubeka nokusebenzisa izinzuzo ze-trichlorethylene ngaphandle kokubeka engcupheni inhlalakahle yempilo yethu neplanethi yethu.
