Hobaneng ha PTFE e Matla a Lesela la Mocheso o Phahameng o Hanela Mollo o Bulehileng? Mokhoa oa Eona oa ho Lahla Lelakabe o Leka ho Menyenyane ke Efe?

Jiangsu Aokai New Materials, moetsi ea ka sehloohong oa masela a mocheso o phahameng oa PTFE, oa hlalosa:

Lesela la PTFE le nang le mocheso o phahameng oa mocheso le sebetsa haholo mollong o bulehileng, haholo-holo ka lebaka la sebopeho sa limolek'hule le mochine oa ho bola ha mocheso oa thepa ea eona ea mantlha - polytetrafluoroethylene (PTFE). Ho lieha ha eona ha lelakabe ha ho itšetlehe ka lintho tse thibelang malakabe tse ekelitsoeng joalo ka lisebelisoa tse tloaelehileng, empa ho tsoa ho inertness ea eona ea tlhaho ea lik'hemik'hale le boitšoaro bo ikhethang ba ho bola.

Sena se ka utloisisoa ka mekhahlelo e meraro:

1. 'Lihlomo' tse Matla tsa Molek'hule: Matla a Bond e Phahameng le Lera la Tšireletso

·  Libonto tse matla tsa carbon-fluorine (C-F) : Limolek'hule tsa PTFE li na le mokokotlo oa ketane ea carbon e pota-potiloeng ke liathomo tsa fluorine. Bonto ea C-F ke e 'ngoe ea li-chemical bond tse matla ka ho fetisisa tse tsejoang, tse nang le matla a bonto a ka bang 485 kJ/mol. Ho hlokahala matla a phahameng haholo (mocheso) ho e senya, ho theha moeli oa pele oa tšireletso.

·  Tšireletso ea liathomo tsa fluorine : Liathomo tse kholo, tse qosoang hampe li tletse, li sebetsa joalo ka lihlomo tse teteaneng tse koalang ketane ea khabone e kahare ka botlalo. Tšitiso ena e thibela boholo ba lik'hemik'hale (ho kenyeletsoa le oksijene) ho fihlella ketane ea khabone mme e thibela ka matla tšebetso ea oxidation e hlokahalang bakeng sa ho tuka.

2. Tšilafalo e sa Chesehang: Depolymerization Ho e-na le ho Chesoa

·  Chain scission before oxidation : Tlas'a mocheso o phahameng, libonto tse batlang li fokola tsa khabone-khabone (C-C) ka hare ho khefu ea PTFE pele ho li-bond tsa C-F. Liketane tsa limolek'hule li qala ho bola pele oksijene e ka kenya letsoho liketsong.

·  Sehlahisoa se ka sehloohong ke monomer : Ha e robeha, PTFE e sebelisa depolymerization , e lokolla li-monomers tsa tetrafluoroethylene (C₂F₄) ho tloha qetellong ea ketane. Thepa e fetoha mouoane ho e-na le ho chesoa ke mollo o mabifi o ntšang mocheso o mongata le likhase tse tukang.

·  Phello ea thibelo ea khase ea khase : Khase ea C₂F₄ e tsoang ho depolymerization e teteaneng ho feta moea 'me e lula haufi le holim'a metsi, e etsa lesela la nakoana la gaseous le fokotsang khatello ea oksijene le ho thibela ho tuka.

3. Karolo e Tšehetsang ea Glass Fiber Substrate

Lesela la mocheso o phahameng oa PTFE ke motsoako o entsoeng ka ho roala PTFE holim'a lesela la fiber ea khalase. Glass fiber ka boeona ke ntho e sa cheng e sa cheng. Joaloka skeleton ea sebopeho, e tiisa hore esita le haeba lesela la PTFE le ka sebelisoa ka ho feletseng tlas'a mocheso o feteletseng, thepa ha e qhibilihe kapa e rotha joaloka polasetiki e hloekileng, ho boloka botšepehi ba mohaho le ho thibela ho ata ha lelakabe.

E lokela ho totobatsoa hore PTFE ha e khone ho chesoa ke malakabe , ha e chese ka ho feletseng. Hangata e mamella mocheso oa nako e telele ho fihla ho 260 ° C 'me e lula e tsitsitse ka nakoana ho 300-360°C.

Ho senyeha ha mollo o bulehileng : Ha o pepesehile ka ho toba mollong o bulehileng (hole ho feta mocheso oa eona oa ho bola), lesela la PTFE le senyeha, empa ts'ebetso ha e hlahise mocheso o lekaneng kapa lintho tse tukang ho boloka mollo. Ha e kopantsoe le tšehetso ea fiber ea khalase, malakabe a ke ke a hasana a sa khaotse.

Ka kakaretso, lesela la PTFE le nang le mocheso o phahameng ha le chese hobane thepa ea eona ea mantlha ea PTFE e entsoe ka molek'hule e le hore e hane ho tuka .

Lintlha tse ka holimo li fanoe ke Jiangsu Aokai New Materials Technology Co., Ltd.

Bakeng sa lintlha tse qaqileng, maemo a ts'ebeliso le litharollo tse ikhethileng tsa lihlahisoa tsa rona tse felletseng - ho kenyelletsa lesela la mocheso o phahameng oa PTFE, tepi ea mocheso o phahameng oa PTFE, lebanta le nang le mocheso o phahameng oa mocheso oa PTFE, lebanta le se nang mochini bakeng sa mechini e tlamang, lesela le nang le lehlakore le le leng la PTFE, lesela le nang le mocheso o phahameng oa mocheso o phahameng oa mocheso le lesela le sa keneleng mocheso le lisebelisoa tse ling tse amanang le rona:
