Litiiso tsa oli tsa PTFE ke eng? Liphapang tsa Bohlokoa, Lisebelisoa, le Tataiso ea Tlhokomelo

Litiiso tsa oli tsa polytetrafluoroethylene (PTFE).ke litharollo tse tsoetseng pele tsa tiiso tse tsebahalang ka ho hanyetsa lik'hemik'hale tse ikhethang, likhohlano tse tlase, le bokhoni ba ho sebetsa maemong a mocheso a feteletseng. Ho fapana le li-elastomer tsa setso joalo ka nitrile (NBR) kapa rabara ea fluorocarbon (FKM), litiiso tsa PTFE li phahamisa thepa e ikhethang ea li-fluoropolymers ho fana ka ts'epo e ke keng ea lekanngoa lits'ebetsong tse hlokang indasteri. Sengoliloeng sena se hlahloba sebopeho, melemo, le tšebeliso ea niche ea litiiso tsa oli tsa PTFE, ho araba lipotso tse tloaelehileng mabapi le ho tlotsa, ho lemoha ho dutla, nako ea bophelo, le tse ling.

## Litsela tsa bohlokoa

• Litiiso tsa oli tsa PTFEli ipabola libakeng tse thata ka lebaka la tlhaho ea tsona e sa tsitsang, mocheso o pharaletseng (-200 ° C ho ea + 260 ° C), le ho hanyetsa lik'hemik'hale, UV le botsofali.

• Ho fapana lenitrilekapaLitiiso tsa FKM, PTFE ha e hloke lubrication lits'ebetsong tse ngata, ho fokotsa litšenyehelo tsa tlhokomelo.

• Lisebelisoa tse tloaelehileng li kenyelletsa lienjineri tsa likoloi, litsamaiso tsa sefofane, lisebelisoa tsa lik'hemik'hale, le mechini ea boemo ba lijo.

• Litiiso tsa PTFE li loketse liindasteri tse etelletsang pele ts'ebetso e se nang tšilafalo, joalo ka meriana le li-semiconductors.

• Tlhophiso e nepahetseng le khetho ea thepa e bohlokoa bakeng sa ho eketsa nako ea bophelo, e ka fetangLilemo tse 10+maemong a nepahetseng.

## Litiiso tsa oli tsa PTFE ke eng?

Tlhaloso le Sebopeho

Litiiso tsa oli tsa PTFE ke li-gaskets tsa mochini tse etselitsoeng ho boloka mafura le ho qhelela litšila ka har'a li-shafts tse bilikang. Sebopeho sa bona hangata se kenyelletsa:

• PTFE Molomo: Moeli oa ho tiisa o fokolang o ikamahanyang le ho se phethahale ha shaft.

• Spring Loader (Ha ho boikhethelo): E matlafatsa matla a radial bakeng sa lits'ebetso tsa khatello e phahameng.

• Metal Case: Ntlo ea tšepe e sa hloekang kapa ea carbon bakeng sa botšepehi ba mohaho.

• Mehele ea Anti-Extrusion: Thibela deformation tlas'a khatello e feteletseng.

Sebopeho sa limolek'hule tsa PTFE-mokokotlo oa carbon o tletseng liathomo tsa fluorine-o fana ka ho se sebetse khahlanong le hoo e batlang e le lik'hemik'hale tsohle, ho akarelletsa le li-acids, solvents, le libeso. Bokaholimo ba eona bo boreleli bo fokotsa ho senyeha le ho lahleheloa ke matla, ho etsa hore e be sebaka se loketseng ho tiisa ka matla.

## PTFE vs. Nitrile le FKM Oil Litiiso: Liphapang tsa Bohlokoa

Hobaneng ha PTFE e Hlōla Libakeng tse thata:

• Dry Running Bokhoni: PTFE ea ho intša lubricating thepa felisa tlhokahalo ea ka ntle greases maemong a mangata, ho fokotsa tšilafalo likotsi.

• Zero Ho ruruha: Ho fapana le li-elastomers, PTFE e hanela ho ruruha ha maro a thehiloeng ho hydrocarbon.

• Tumellano ea FDA: PTFE e amohetsoe bakeng sa likopo tsa lijo le tsa meriana.

## Likopo le Melao-motheo ea ho sebetsa

Litiiso tsa Oli tsa PTFE li sebelisoa Hokae?

1. Tsa makoloi: Li-shafts tsa Turbocharger, litsamaiso tsa phetisetso, le sistimi ea ho futhumatsa betri ea EV.

2. Sepakapaka: Li-actuator tsa Hydraulic le likarolo tsa enjene ea jete.

3. Tšebeliso ea Lik'hemik'hale: Lipompo le li-valve tse sebetsanang le mecha ea litaba e mabifi joaloka sulfuric acid.

4. Li-semiconductors: Likamore tsa vacuum le lisebelisoa tsa plasma etching.

5. Lijo & Pharma: Li-mixer le mechini e tlatsang e hlokang litiiso tse lumellanang le FDA.

Litiiso tsa PTFE li sebetsa Joang?

Litiiso tsa PTFE li sebetsa ka:

• Adaptive Tiiso: Molomo oa PTFE o lumellana le ho feto-fetoha ho honyenyane ha shaft kapa ho se tloaelehe ha bokaholimo.

• Moloko o Monyenyane oa Mocheso: Khohlano e tlase e fokotsa ho senyeha ha mocheso.

• Tiiso e tsitsitseng le e Matla: E sebetsa maemong a mabeli a emeng le a lebelo le phahameng (ho fihla ho 25 m/s).

## Tataiso ea ho Lubrication: Na Litiiso tsa PTFE li Hloka Mafura?

PTFE's lubricity ea tlhaho hangata e felisa tlhoko ea mafura a kantle. Leha ho le joalo, maemong a boima kapa a lebelo le phahameng,likhase tse entsoeng ka siliconekapaPFPE (perfluoropolyether) olili buelloa ka lebaka la ho lumellana ha tsona le botsitso ba mocheso. Qoba li-grease tse thehiloeng ho petroleum, tse ka theolang PTFE ha nako e ntse e ea.

## Mokhoa oa ho lemoha ho lutla ha Setiiso sa Oli

1. Tlhahlobo ea Pono: Batla masala a oli ho potoloha matlo a tiiso.

2. Teko ea Khatello: Kenya khatello ea moea ho hlahloba hore na ha ho na lipululana tse phonyohang.

3. Metrics ea Ts'ebetso: Lekola li-spikes tsa mocheso kapa ho eketseha ha tšebeliso ea matla, ho bonts'a khohlano e tsoang ho tiiso e hlolehang.

## Nako ea Bophelo ea Oli ea Enjene: Lintlha le Litebello

Litiiso tsa oli tsa PTFE lienjineng hangata li tšoarella8-12 lilemo, ho ipapisitsoe le:

• Maemo a Tshebetso: Lithempereichara tse feteletseng kapa litšila tse senyang li fokotsa nako ea bophelo.

• Tlhophiso Boleng: Ho se tsamaisane hantle nakong ea ho lekana ho baka ho roala pele ho nako.

• Kereiti ea lintho tse bonahalang: Metsoako e matlafalitsoeng ea PTFE (mohlala, e tletseng likhalase) e matlafatsa nako e telele.

Ha ho bapisoa, litiiso tsa nitrile lienjineng li nka lilemo tse 3-5, athe FKM e nka lilemo tse 5-7.

## Mekhoa ea Indasteri: Hobaneng Litiiso tsa PTFE li ntse li tuma

• Moshoelella: Bophelo bo bolelele ba PTFE bo fokotsa litšila ha bo bapisoa le ho nkela elastomer khafetsa.

• Likoloi tsa Motlakase (EVs): Tlhokahalo ea litiiso tse hananang le li-coolants le matla a phahameng a motlakase a ntse a phahama.

• Indasteri 4.0: Litiiso tse bohlale tse nang le li-sensor tse kentsoeng bakeng sa tlhokomelo e boletsoeng esale pele lia hlaha.

## LBH

P: Na litiiso tsa PTFE li ka sebetsana le maemo a vacuum?
A: E, PTFE's low gassing e etsa hore e be e loketseng bakeng sa lisebelisoa tsa vacuum tlhahiso ea semiconductor.

P: Na litiiso tsa PTFE li ka sebelisoa hape?
A: Le ha PTFE ka boyona e sa sebetse, ho botjha ho hloka mekgwa e kgethehileng. Baetsi ba bangata ba fana ka mananeo a ho khutlisetsa morao.

P: Ke eng e etsang hore litiiso tsa PTFE li hlolehe pele ho nako?
A: Ho kenya ka mokhoa o fosahetseng, ho se lumellane ha lik'hemik'hale, kapa ho feta meeli ea khatello (hangata> 30 MPa).

P: Na o fana ka meralo ea tiiso ea PTFE?
A: E, [Lebitso la K'hamphani ea Hao] e fana ka litharollo tse hlophisitsoeng bakeng sa litekanyo tse ikhethang tsa shaft, likhatello le mecha ea litaba.

## Qetello
Litiiso tsa oli tsa PTFE li emela sehlohlolo sa theknoloji ea ho tiisa, e fanang ka ts'ebetso e ke keng ea lekanngoa liindastering moo ho hloleha e seng khetho. Ka ho utloisisa melemo ea bona ho feta nitrile le FKM, ho khetha lubrication e nepahetseng, le ho latela mekhoa e metle, likhoebo li ka fokotsa haholo nako le litšenyehelo tsa ts'ebetso.
