Kungani I-PTFE Indwangu Yokushisa Okuphezulu Iba Nzima Futhi Ibhibhile Ngemva Kokusetshenziswa Isikhathi Eside Emazingeni Okushisa Aphezulu?

I-Jiangsu Aokai New Materials, umkhiqizi womthombo wendwangu ye-PTFE eshisa kakhulu, uchaza ukuqina kanye nokufiphala kwendwangu ye-PTFE enezinga eliphezulu lokushisa ngemva kwesevisi ende yezinga lokushisa eliphezulu kusuka emibonweni emithathu: ukuphumula kweketango le-polymer, ukuxhumanisa, kanye nokuwohloka . Kumele kuqashelwe ukuthi impahla ewumgogodla yendwangu ye-PTFE ephezulu yokushisa i-polytetrafluoroethylene (PTFE), futhi ukuhlaziya okulandelayo kugxile ekushintsheni kwe-microstructural yendwangu ye-PTFE ephezulu.

I. I-Molecular Chain Relaxation (Ukuguga ngokomzimba)

Emazingeni okushisa aphezulu, ukuhamba kwamaketanga wamangqamuzana ezifundeni ze-amorphous ze-PTFE izinga lokushisa eliphezulu kwendwangu kuyanda, futhi kancane kancane aguquke abe yisimo se-crystalline esimisiwe, okuholela ekukhanyeni okuphezulu. Le nqubo yokuphumuza iketango inciphisa ukuhamba kwamasegimenti amangqamuzana endwangu ye-PTFE enezinga lokushisa eliphezulu, ebonakala ngokukhulu njengezinto eziguqukayo ukusuka kokuguquguqukayo kuye kokuqinile nokushwabana.

II. I-Cross-Linking Reaction

Lapho indwangu ye-PTFE enezinga eliphezulu lokushisa ibonakala emazingeni okushisa aphakeme isikhathi eside (ikakhulukazi eduze noma kweqa umkhawulo wayo wesevisi ongaphezulu), lapho kukhona umkhondo we-oksijini noma imisebe, ama-molecule e-PTFE alahlekelwa ama-athomu e-fluorine ukuze akhe ama-radicals mahhala, abese eqala ukuxhumanisa kwe-intermolecular cross-linking. Inethiwekhi exhunywe ngokuphambanayo ikhawulela ngokuqondile ukuslayida okuhlobene kwamaketanga emolekyuli kwindwangu ye-PTFE yezinga lokushisa eliphezulu, okuyenza ilahlekelwe ukuguquguquka. Lesi ngesinye sezizathu zamakhemikhali ezibalulekile zokuqina kanye nokufiphala kwendwangu ye-PTFE esezingeni lokushisa eliphezulu.

III. Ukusabela Kokwehliswa

Emazingeni okushisa aphakeme noma lapho kukhona umoya-mpilo, amaketanga ayinhloko e-PTFE indwangu eshisa kakhulu aphuka futhi alulaze, akhiqize izingcezu ezinesisindo esiphansi futhi akhiphe amagesi e-fluoride. Nakuba izinto zingase zithambe ekuqaleni, ukuwohloka okuqhubekayo kuholela ekwehleni okubukhali kwesisindo samangqamuzana nokulimala kwesakhiwo sokuqala sekristalu. Ekugcineni, ingaphezulu le-PTFE izimpushana zendwangu yezinga lokushisa eliphezulu, ukuqhekeka, futhi libonisa ukumbathisa okungenakulungiseka.

Isifinyezo : Uma indwangu ye-PTFE yokushisa ephezulu ishisiswe isikhathi eside, ukuphumula kweketango (crystallization) nokuxhumanisa ndawonye kubangela ukuqina nokulahlekelwa kokuqina; ngaphansi kwezimo ezinzima, ukucekelwa phansi kuphinde kucekele phansi ubuqotho besakhiwo. Inhlanganisela yalezi zici ezintathu ekugcineni yenza indwangu ye-PTFE enezinga eliphezulu lokushisa ibe nzima futhi ibe brittle.

Ulwazi olungenhla lunikezwe i-Jiangsu Aokai New Materials Technology Co., Ltd.

Uma ufisa ukufunda kabanzi mayelana nemingcele enemininingwane, izimo zohlelo lokusebenza nezixazululo ezenziwe ngokwezifiso zohlu oluphelele lomkhiqizo wethu, okuhlanganisa indwangu ye-PTFE yokushisa okuphezulu, i-PTFE itheyiphu yokushisa ephezulu, ibhande le-PTFE elinezinga eliphezulu lokushisa, amabhande angenamthungo emishini yokubopha, indwangu ye-PTFE enohlangothi olulodwa, indwangu yengilazi ekwazi ukumelana nokushisa okuphezulu, indwangu yengilazi ekwazi ukumelana nokushisa okuphezulu sicela usithinte ngokusebenzisa iziteshi ezilandelayo:
