Li-composite tsa PTFE tse Tsoetseng Pele: Papiso ea Tekheniki ea Fiber ea Khalase, Fiber ea Carbon, le Li-Filler tsa Graphite

Polytetrafluoroethylene (PTFE), e tsebahalang e le "morena oa polasetiki," e fana ka khanyetso e ikhethang ea lik'hemik'hale, coefficient e tlase ea khohlano, le botsitso maemong a mocheso o feteletseng. Leha ho le joalo, mefokolo ea eona ea tlhaho - joalo ka khanyetso e mpe ea ho tsofala, ho ba thata ho tlase, le ho ba kotsing ea ho thekesela - e susumelitse nts'etsopele eaMetswako ea PTFEKa ho kenyelletsa li-filler tse kang fiber ea khalase, fiber ea carbon, le graphite, bahlahisi ba ka fetola thepa ea PTFE bakeng sa lits'ebetso tse thata ho tiiseng ea lifofane, likoloi le indasteri. Sengoloa sena se hlahloba kamoo li-filler tsena li ntlafatsang PTFE kateng 'me se fana ka tataiso ea ho khetha motsoako o nepahetseng ho latela litlhoko tsa ts'ebetso.

1. Tlhoko ea Phetoho ea PTFE​

PTFE e hloekileng e ipabola ho hanyetsaneng le mafome le khohlano e tlase empa e na le bofokoli ba mechini. Mohlala, ho hanyetsa ha eona ho tsofala ha hoa lekana bakeng sa lits'ebetso tsa ho tiisa ka matla, 'me e fetoha sebopeho tlas'a khatello e tsoelang pele (phallo e batang). Li-filler li sebetsana le mathata ana ka ho sebetsa e le masapo a matlafatsang ka har'a matrix ea PTFE, ho ntlafatsa ho hanyetsa ho thekesela, mamello ea ho tsofala, le ho tsamaisa mocheso ntle le ho beha melemo ea eona ea mantlha kotsing.

2. Faeba ea Khalase: Sesebelisoa sa ho Matlafatsa se Sebetsang ka Theko e Tlase​

Matlotlo a Bohlokoa​

Ho Hanela ho Tshwara: Faeba ya khalase (GF) e fokotsa sekgahla sa ho tshwara ha PTFE ka makgetlo a fihlang ho a 500, e leng se etsang hore e be ntle bakeng sa dibaka tse nang le mojaro o mongata.

Phokotso ea ho Kena: GF e ntlafatsa botsitso ba litekanyo, e fokotsa ho fetoha ha lintho tlas'a khatello e tsoelang pele.

Meeli ea Thempereichara le ea Lik'hemik'hale: GF e sebetsa hantle mochesong o fihlang ho 400°C empa ea senyeha ka har'a asiti ea hydrofluoric kapa metheo e matla.

Likopo​

PTFE e matlafalitsoeng ke GF e sebelisoa haholo litiisong tsa hydraulic, lisilindara tsa pneumatic, le li-gasket tsa indasteri moo matla a mechini le ts'ebeliso e ntle ea litšenyehelo li etelloang pele. Ho lumellana ha eona le lintho tse ling tse kang MoS₂ ho ntlafatsa taolo ea khohlano le ho feta.

3. Faeba ea Khabone: Khetho ea Ts'ebetso e Phahameng​

Matlotlo a Bohlokoa​

Matla le ho Tiea: Faeba ea khabone (CF) e fana ka matla a ho thaepa a holimo le modulus ea ho teneha, e hlokang li-filler tse tlase ho feta GF ho fihlela matlafatso a tšoanang.

Ho tsamaisa mocheso: CF e ntlafatsa ho qhalana ha mocheso, e leng sa bohlokoa bakeng sa lits'ebetso tse potlakileng haholo.

Ho se Sebete ha Lik'hemik'hale: CF e hanela li-acid tse matla (ntle le li-oxidizer) 'me e loketse libaka tse thata tsa lik'hemik'hale.

Likopo​

Metswako ya CF-PTFE e ipabola haholo ho di-absorber tsa ho tshoha ha koloi, disebedisweng tsa semiconductor, le dikarolong tsa sefofane, moo ho tshwarella ha bobebe le taolo ya mocheso di leng bohlokwa.

4. Graphite: Setsebi sa ho tlotsa​

Matlotlo a Bohlokoa​

Khohlano e Tlase: PTFE e tletseng graphite e fihlella di-coefficient tsa khohlano tse tlase ho 0.02, e fokotsang tahlehelo ya matla ditsamaisong tse fetohang.

Ho Tsitsisa Thempereichara: Graphite e ntlafatsa ho tsamaisa mocheso, e thibela ho bokellana ha mocheso ka har'a likhokahano tse lebelo le phahameng.

Ho Tsamaellana ha Bonolo: E fokotsa ho tsofala ha libaka tse bonolo joalo ka aluminium kapa koporo.

Likopo​

Metswako e thehilweng ho grafiti e ratwa haholo dibering tse sa tlotswang, ditiisong tsa compressor, le mechining e potolohang moo tshebetso e boreleli le ho qhalana ha mocheso di leng bohlokwa.

5. Kakaretso ea Papiso: Ho Khetha Setlatsetsi se Nepahetseng​

Metswako ea Synergistic

Ho kopanya di-filler—mohlala, faeba ya khalase e nang le MoS₂ kapa faeba ya khabone e nang le graphite—ho ka ntlafatsa thepa e mengata. Mohlala, di-hybrid tsa GF-MoS₂ di fokotsa kgohlano ha di ntse di boloka ho hanyetsa ho tsofala.

6. Litlamorao bakeng sa Indasteri le Botsitso​

Metswako ya PTFE e tlatsitsweng e atolosa bophelo ba dikarolo, e fokotsa makgetlo a tlhokomelo, mme e ntlafatsa bokgoni ba ho boloka matla. Mohlala, ditiiso tsa graphite-PTFE ditsamaisong tsa LNG di mamella mocheso ho tloha ho -180°C ho isa ho +250°C, di sebetsa hantle ho feta thepa e tlwaelehileng. Dintlafatso tsena di tsamaellana le dipheo tsa moruo o chitja ka ho fokotsa ditshila ka moralo o tshwarellang.

Qetello​

Khetho ea filler—khalase ea khalase, khabone ea fiber, kapa graphite—e laola ts'ebetso ea metsoako ea PTFE. Leha khabone ea khalase e fana ka litšenyehelo tse leka-lekaneng le ho tšoarella, khabone ea fiber e ipabola maemong a feteletseng, 'me graphite e beha setlolo pele. Ho utloisisa liphapang tsena ho nolofalletsa baenjiniere ho etsa litharollo tsa ho koala bakeng sa ts'epo le katleho.

Ha liindasteri li ntse li tsoela pele ho ea maemong a holimo a ts'ebetso, ho sebelisana le litsebi tsa mahlale a thepa ho netefatsa nts'etsopele e ntle ea sehlahisoa. Ningbo Yokey Precision Technology e sebelisa boiphihlelo bo tsoetseng pele ba ho kopanya ho fana ka litiiso tse fihlelang litlhoko tse thata bakeng sa lits'ebetso tsa likoloi, matla le indasteri.

Mantsoe a bohlokoa: metsoako ea PTFE, litharollo tsa ho tiisa, boenjiniere ba thepa, lits'ebetso tsa indasteri
