Perchlorethylene, e tsejoang hape e letetrachlorethylene, ke motsoako oa tlhaho o nang le foromo ea C2Cl4 'me ke mokelikeli o se nang mebala. E fetohile motsoako oa bohlokoa lits'ebetsong le lits'ebetsong tse fapaneng tsa indasteri. Ho sa tsotellehe bohlokoa ba eona, ho na le khaello ea tlhokomeliso ka ntho ena e sebetsang ka mefuta-futa. Ka hona, ho hlakisa perchlorethylene, ho sekaseka thepa ea eona, ho lekola ts'ebeliso ea eona, le ho utloisisa lintlha tsa polokeho ea eona ho ile ha fetoha bohlokoa. Ka boithuto bo tebileng ba likarolo tsena, pampiri ena e ikemiselitse ho fa babali tsebo e felletseng ea perchlorethylene.
Lintho tse molemo tsa perchlorethylene:
Perchlorethylene ke mokelikeli o se nang 'mala o sa cheng o bonts'ang tatso e monate maemong a holimo. Foromo ea molek'hule ke C2Cl4 'me e na le liathomo tse peli tsa carbon le liathomo tse' nè tsa chlorine. E na le botsitso bo babatsehang, ha e sebetsane le lintho tse ngata, le matla a phahameng a solvent.
Tšebeliso ea perchlorethylene:
1. Ho hloekisa ka mokhoa o omileng: E 'ngoe ea lisebelisoa tse ratoang ka ho fetisisa tsa perchlorethylene ke indastering ea ho hloekisa e omileng. Ho se chese ha eona, ho qhibiliha ho holimo le ntlha e tlaase ea ho bela ho etsa hore e be mokelikeli o loketseng bakeng sa ho tlosa litšila le litšila masela. Bokhoni ba perc ba ho qhala oli le metsoako ea lintho tse phelang bo netefatsa tlhoekiso e sebetsang ntle le ho senya lisebelisoa tse senyehang.
2. Metal degreasing: Thepa e matla ea degreasing ea perchlorethylene e boetse e loketse indasteri ea ho sebetsa ka tšepe. E atisa ho sebelisoa ho tlosa mafura, oli le litšila tse sa batleheng likarolong tsa tšepe pele ho ts'ebetso e tsoelang pele kapa ho phekola holimo. Ho lumellana ha perchlorethylene le litšepe tse fapa-fapaneng, ho kenyelletsa aluminium, tšepe le koporo, ho etsa hore e be solvent e sebetsang ts'ebetsong ea tšepe ea tšepe.
3. Ho etsoa ha lik'hemik'hale: Perchlorethylene e sebetsa e le lik'hemik'hale tse ka hare ho tlhahiso ea metsoako e sa tšoaneng. E sebetsa e le selelekela sa tlhahiso ea vinyl chloride, e sebelisoang hape ho hlahisa polyvinyl chloride (PVC). Ho phaella moo, e boetse e sebelisoa ha ho etsoa lipente, li-adhesives, rabara le meriana.
Mehato ea tšireletso:
1. Tšireletseho mosebetsing: Joalo ka ntho leha e le efe ea lik'hemik'hale, mehato e loketseng ea tšireletso e lokela ho nkoa ha ho sebelisoa perchlorethylene. Apara lisebelisoa tse loketseng tsa ho itšireletsa (PPE), joalo ka liatlana le likhalase, ho thibela ho kopana ka kotloloho. Sebaka sa ho sebetsa se nang le moea o motle le sistimi ea tlhoekiso ea moea li bohlokoa ho fokotsa ho pepesehela mouoane oa lik'hemik'hale.
2. Tšusumetso ea tikoloho: Ka lebaka la bokhoni ba eona ba ho silafatsa mobu, moea le metsi, perchlorethylene e khetholloa e le kotsi ea tikoloho. Tsamaiso e nepahetseng ea litšila le mekhoa ea ho lahla li phetha karolo ea bohlokoa ho thibela tšenyo ea tikoloho. Ho khothaletsoa ho sebelisa hape kapa ho lahloa ka nepo ha perc e sebelisitsoeng ho fokotsa ho lokolloa ha eona tikolohong.
3. Likotsi tsa bophelo bo botle: Ho pepesehela vinyl chloride ka nako e telele ho ka ba le liphello tse mpe tsa bophelo bo botle, ho akarelletsa le mathata a ho hema, ho tsekela le ho ruruha ha letlalo. Ka hona, ho bohlokoa hore basebetsi ba fumane koetliso e nepahetseng mabapi le mekhoa e sireletsehileng ea ho sebetsana le maemo le ho latela meeli e behiloeng ea ho pepeseha.
Qetello:
Qetellong, perchlorethylene e bohlokoa haholo liindastering tse 'maloa, haholo-holo ho hloekisa ka mokhoa o omileng, ho hloekisa tšepe le ho etsa lik'hemik'hale. Kutloisiso e phethahetseng ea likarolo tsa eona, lits'ebetso, le lintlha tsa ts'ireletso li bohlokoa ho netefatsa tšebeliso e nepahetseng le ho fokotsa kotsi. Ka ho tloaelana le liphiri tsa motsoako ona o nang le mekhoa e mengata, re ka etsa liqeto tse nang le tsebo 'me ra etsa hore ho be le tikoloho e sireletsehileng bakeng sa tšebeliso ea eona.
