Mayelana:
I-Perchlorethylene, obeye aziwe njengoi-tetrachlorethylene, iyinhlanganisela yemvelo enefomula C2Cl4 futhi iwuketshezi olungenambala. Sekuyinhlanganisela eyinhloko ezinqubweni ezihlukahlukene zezimboni kanye nezicelo. Naphezu kokubaluleka kwayo, kukhona ukuntula ukuqwashisa ngale nto ehlukahlukene. Ngakho-ke, ukucacisa i-perchlorethylene, ukuhlaziya izakhiwo zayo, ukuhlola ukusetshenziswa kwayo, nokuqonda ukucatshangelwa kwayo kokuphepha kwaba semqoka. Ngokucwaninga okujulile kwalezi zici, leli phepha lihlose ukunikeza abafundi ulwazi olubanzi lwe-perchlorethylene.
Izici ze-perchlorethylene:
I-Perchlorethylene iwuketshezi olungashi olungenambala olubonisa ukunambitheka okumnandi ekugxilweni okuphezulu. I-molecular formula yi-C2Cl4 futhi iqukethe ama-athomu e-carbon amabili nama-athomu amane e-chlorine. Inokusimama okuhle kakhulu, ukungasabeli nezinto eziningi, namandla okuncibilikisa aphezulu.
Ukusetshenziswa kwe-perchlorethylene:
1. Ukuhlanza okomile: Enye yezinto ezisetshenziswa kakhulu i-perchlorethylene isembonini yokuhlanza okomile. Ukungashi kwayo, ukuncibilika okuphezulu kanye nephuzu eliphansi lokubilisa kuyenza ibe isincibilikisi esikahle sokususa amabala nokungcola ezindwangu. Ikhono lika-perc lokuncibilikisa amafutha nezinhlanganisela eziphilayo liqinisekisa ukuhlanzwa okuphumelelayo ngaphandle kokulimaza izinto ezintekenteke.
2. I-Metal degreasing: Izakhiwo eziqinile zokunciphisa i-perchlorethylene nazo zifanelekile embonini yokucubungula insimbi. Ivamise ukusetshenziselwa ukususa amafutha, uwoyela, nokungcola okungafuneki ezingxenyeni zensimbi ngaphambi kokucubungula okwengeziwe noma ukwelashwa kwendawo. Ukuhambisana kwe-perchlorethylene enezinsimbi ezihlukahlukene, okuhlanganisa i-aluminium, insimbi, nethusi, kuyenza i-solvent ephumelelayo enqubweni yokushisa insimbi.
3. Ukukhiqizwa kwamakhemikhali: I-Perchlorethylene isebenza njengekhemikhali ephakathi ekukhiqizeni izinhlanganisela ezihlukahlukene. Isebenza njengesandulela sokwenziwa kwe-vinyl chloride, esetshenziswa futhi ekukhiqizeni i-polyvinyl chloride (PVC). Ngaphezu kwalokho, ibuye isetshenziswe ekuhlanganiseni amapende, ama-adhesives, irabha kanye nemithi.
Izinyathelo zokuphepha:
1. Ukuphepha emsebenzini: Njenganoma iyiphi into yamakhemikhali, izinyathelo ezifanele zokuphepha kufanele zithathwe lapho kusingathwa i-perchlorethylene. Gqoka izinto zokuzivikela ezifanele (i-PPE), njengamagilavu nezibuko, ukuze uvimbele ukuthintana okuqondile. Indawo yokusebenza enomoya omuhle kanye nesistimu yokuhlanza umoya kubalulekile ukuze kuncishiswe ukuchayeka kumhwamuko wamakhemikhali.
2. Umthelela wendawo: Ngenxa yamandla ayo okungcolisa umhlabathi, umoya namanzi, i-perchlorethylene ihlukaniswa njengengozi engokwemvelo. Ukuphathwa kwemfucuza ngendlela efanele kanye nezinqubo zokulahla kudlala indima ebalulekile ekuvimbeleni ukulimala kwemvelo. Ukugaywa kabusha noma ukulahlwa okufanele kwe-perc esetshenzisiwe kuyanconywa ukuze kuncishiswe ukukhululwa kwayo endaweni.
3. Izingozi zempilo: Ukuchayeka isikhathi eside ku-vinyl chloride kungaba nemiphumela emibi yezempilo, okuhlanganisa izinkinga zokuphefumula, isiyezi nokuluma kwesikhumba. Ngakho-ke, kubalulekile ukuthi abasebenzi bathole ukuqeqeshwa okufanele ngezinqubo zokuphatha ngokuphephile futhi bahambisane nemikhawulo ebekiwe yokuchayeka.
Isiphetho:
Sengiphetha, i-perchlorethylene ibaluleke kakhulu ezimbonini eziningana, ikakhulukazi ekuhlanzeni okomile, ukukhishwa kwensimbi nokukhiqizwa kwamakhemikhali. Ukuqonda okuphelele kwezici zayo, izinhlelo zokusebenza, nokucatshangelwa kokuvikeleka kubalulekile ukuze kuqinisekiswe ukusetshenziswa okuphelele nokunciphisa ubungozi. Ngokujwayelana nezimfihlo zale nhlanganisela enemisebenzi eminingi, singenza izinqumo ezinolwazi futhi sikhuthaze indawo ephephile ukuze isetshenziswe.
