Ts'ebetso ea tlhahiso ea PTFE haholo-holo e kenyelletsa mehato e 4 e meholo e latelang:
1. motsoako oa monomer
PTFEke polymerization ea tetrafluoroethylene (TFE) monomer polymerization ea metsoako ea polymer.monomer synthesis ea TFE ke mohato oa pele oa ts'ebetso ea tlhahiso ea PTFE.Hajoale, indasteri e sebelisa mokhoa oa electrolytic fluorination ho lokisa TFE monomer, ke hore, anhydrous hydrogen fluoride le ethylene tlasa maemo a itseng bakeng sa karabelo ea electrolysis ho hlahisa TFE monomer.
2.Polymerization reaction
TFE monomer ka mocheso o itseng le khatello, eketsa catalyst le solvent, polymerization reaction.Nakong ea karabelo ea polymerization, TFE monomer e tsoela pele ho etsoa polymerized ho theha boima ba molek'hule PTFE, mocheso, khatello, mofuta oa catalyst le mahloriso a mokhoa oa polymerization le lintlha tse ling li tla ama boima ba limolek'hule, sebopeho le thepa ea PTFE.
3.Ka mor'a phekolo
Kamora hore karabelo ea polymerization e phetheloe, kalafo ea morao-rao ea hlokahala ho fumana lihlahisoa tse hloekileng tsa PTFE.Kalafo ea ka morao haholo-holo e kenyelletsa ho hlatsoa, ho omisa, ho senya, ho sieving le mehato e meng ea ho tlosa li-catalysts, solvents le litšila tse ling ho fumana likaroloana tse hloekileng tsa PTFE.
4.Molding mokhoa
PTFE resin likaroloana ba bōptjoa tlas'a maemo a itseng ho fumana ho hlokahalaPLihlahisoa tsa TFE.Mekhoa ea ho bopa e kenyelletsa extrusion, ho bopa ente, calendering joalo-joalo, ho latela litlhoko tse fapaneng tsa lihlahisoa ho khetha mokhoa o nepahetseng oa ho bopa.Mold process mocheso, khatello, lebelo la ho sebetsa le lintlha tse ling li tla ama ts'ebetso le boleng ba lihlahisoa tsa PTFE.
Lintho tse tala tsa PTFE
Polytetrafluoroethylene (PTFE) resin e ile ea fumanoa ka phoso ke bo-rasaense ba Amerika ka laboratoring ka 1936, 'me hona joale lefats'e le ka hlahisa PTFE linaheng tse ka tlaase ho 20, tseo boholo ba tsona e leng linaha tse tsoetseng pele.Chaena lilemong tsa bo-60 ho tseba theknoloji ea tlhahiso le ho hlokomela tlhahiso, e fetohile moreki e moholo oa PTFE, moo lihlahisoa tse tlaase li 'nileng tsa e-ba ngata ho feta tlhokahalo, empa lihlahisoa tse ngata tse phahameng li ntse li hloka ho itšetleha ka thepa e tsoang linaheng tse tsoetseng pele. .
Lihlahisoa le lihlahisoa tsa China tsa hajoale tsa PTFE li rekoa haholo ho tsoa United States, Japane le linaha tsa Europe.Ka lebaka la litšenyehelo tsa lipalangoang le potoloho ea phepelo, China ho reka Japane e atileng ka ho fetesisa, le thepa ea Japane ea lihlahisoa tsa PTFE tsa boleng bo botle ho fihlela tlhoko ea lehae ea maemo a holimo.
Ho ea ka maikutlo a bareki ba ho qetela, lihlahisoa ka matla a mochine a ts'ebeliso ea sebele ea maemo a ho sebetsa, khanyetso ea creep le botsitso bo phahameng le bo tlaase ba mocheso, thepa e tsoang linaheng tse ling e molemo ho feta thepa ea malapeng.
Ho reka li-tubing tse nepahetseng tsa PTFE ha se feela ka ho khetha litlhaloso tse fapaneng bakeng sa lits'ebetso tse fapaneng.Ho feta ho khetha moetsi ea ka tšeptjoang.Besteflon Fluorine plastic Industry Co., Ltd. e sebetsa ka ho khetheha ho hlahiseng liphaephe tsa boleng bo holimo tsa PTFE le li-tubes ka lilemo tse 20.Haeba ho na le lipotso le litlhoko, ka kopo ikutloe u lokolohile ho ikopanya le rona bakeng sa likeletso tse ling tsa litsebi.
