Tšusumetso ea Phetoho ea PTFE Indastering ea Valve: Ho Ntlafatsa Ts'ebetso, Ho Tšoarella le Polokeho

1. Selelekela:PTFEe le Mofetoheli oa Lipapali Theknolojing ea Valve​

Li-valve ke likarolo tsa bohlokoa litsamaisong tsa taolo ea mokelikeli, moo ts'ebetso e amang ka ho toba polokeho, katleho le litšenyehelo tsa ts'ebetso. Leha litšepe tse kang tšepe e sa hloekang kapa li-alloy li 'nile tsa laola kaho ea li-valve ka tloaelo, li thatafalloa ke ho bola, ho tsofala le tlhokomelo e phahameng libakeng tse mabifi.Polytetrafluoroethylene (PTFE), fluoropolymer e sebetsang hantle haholo, e hlalositse moralo oa valve bocha ka ho sebetsana le mefokolo ena. Thepa ea eona e ikhethang—ho se sebetse hantle ha lik'hemik'hale, ho mamella mocheso, le ho itlotsa—e nolofalletsa li-valve ho sebetsa ka mokhoa o tšepahalang lits'ebetsong tse senyang, tse hloekileng haholo, kapa tse feteletseng. Sengoloa sena se hlahloba kamoo PTFE e ntlafatsang ts'ebetso ea li-valve ho pholletsa le liindasteri, ho tloha ts'ebetsong ea lik'hemik'hale ho ea ho meriana, le karolo ea eona ho khanneng boqapi theknolojing ea ho tiisa le saense ea thepa.

2. Kamoo PTFE e Sebetsanang le Mathata a Bohlokoa a Valve​

Sebopeho sa limolek'hule sa PTFE, se khetholloang ka litlamo tse matla tsa carbon-fluorine, se fana ka motsoako oa thepa e hlōlang ho hloleha ho tloaelehileng ha li-valve:

Ho se Sebete ha Lik'hemik'hale: PTFE e hanela hoo e ka bang mefuta eohle e mabifi, ho kenyeletsoa le li-acid tse matla (mohlala, sulfuric acid), alkalis le li-solvents tsa organic. Sena se felisa ho lutla ho bakoang ke mafome, e leng bothata bo atisang ho hlaha li-valve tsa tšepe.

Mamello e Batsi ea Mocheso: Ka mefuta e sebetsang ea -200°C ho isa ho +260°C, PTFE e boloka ho tenyetseha lits'ebetsong tsa cryogenic le botsitso mouoaneng oa mocheso o phahameng, e fokotsa ho hloleha ha valve ho potoloha ha mocheso.

Ho qabana ho Tlase le Bokaholimo bo sa Khomareleng: PTFE's coefficient of friction (~0.04) e fokotsa torque ea actuation mme e thibela ho bokellana ha thepa (mohlala, li-polymer kapa likristale), e netefatsa ts'ebetso e boreleli mecheng ea viscous kapa slurry.

Ho se be le Tshilafatso: Jwalo ka thepa e hlwekileng, PTFE e fihlela maemo a bohloeki bakeng sa meriana le ts'ebetso ya dijo, e qoba tšilafalo ya dihlahiswa.

Litšobotsi tsena li lumella PTFE ho eketsa nako ea bophelo ba valve ka makhetlo a 3-5 ha e bapisoa le thepa e tloaelehileng, ha e ntse e fokotsa makhetlo a tlhokomelo le nako ea ho se sebetse.

3. Lintlafatso tsa Bohlokoa Likarolong tsa Valve tse Thehiloeng ho PTFE

3.1 Mekhoa e Tsoetseng Pele ea ho Tiisa​

PTFE e fetola ho tiisoa ha valve ka meralo e lefellang ho tsofala le ho feto-fetoha ha khatello:

Li-filler tsa PTFE tse nang le khoune: Ha li nkela liphutheloana tsa setso tse nang le sebopeho sa V sebaka, li-filler tsa PTFE tse nang le khoune tse nang le tšepe e sa hloekang sebaka li fana ka khatello ea ho tiisa e ikamahanyang le maemo. Tlas'a khatello ea kahare, moralo oa khoune o tiea ka matla, o thibela ho lutla ha lits'ebetso tsa potoloho e phahameng.

Meqolo ea PTFE-Graphite ea Mealo e Mengata: Ka har'a likutu tsa li-valve, metsoako ea PTFE-graphite e arotsoeng ka mekhahlelo e boloka botšepehi ba tiiso tlas'a liphetoho tsa mocheso. Mealo ea PTFE e netefatsa ho hanyetsa lik'hemik'hale, ha graphite e ntlafatsa ho tsamaisoa ha mocheso, e fokotsa ho petsoha ha khatello.

3.2 Mebele ea Li-valve tse nang le Mehala​

Bakeng sa tšireletso e felletseng ea ho kopana le mokelikeli, li-valve li sebelisa lesela la PTFE—lera la 2-5 mm le hokahaneng le 'mele ea li-valve tsa tšepe. Mokhoa ona o arola mecha ea litaba e senyang ho tsoa holim'a tšepe, e leng ea bohlokoa bakeng sa ho sebetsana le litharollo tsa hydrochloric acid kapa chlorine. Mekhoa ea sejoale-joale ea lesela, joalo ka ho bopa isostatic, e netefatsa hore e koahetsoe ka mokhoa o ts'oanang ntle le likheo, e leng sa bohlokoa bakeng sa ho thibela ho bola ha sebaka.

3.3 Li-Internal tse koahetsoeng ka PTFE​

Dikarolo tse kang dibolo, di-disc, kapa diaphragm tse manehilweng ka PTFE di kopanya matla a sebopeho sa tshepe le ho hanyetsa ho bola ha fluoropolymer. Mohlala, di-valve tsa bolo, dibolo tse manehilweng ka PTFE di fihlella ho kwalwa ho tiileng ka di-bubble (ISO 5208 Class VI) ha di ntse di hanela ho bola ha galvanic.

4. Papiso ea Tshebetso: Li-valve tsa PTFE khahlanong le Li-valve tse Tloaelehileng​

5. Tšusumetso ea Litharollo tsa Valve ea PTFE ho Indasteri ka Bophara

Ts'ebetso ea Lik'hemik'hale: Li-valve tsa bolo tse nang le PTFE liphaepheng tsa sulfuric acid li fokotsa liketsahalo tsa ho lutla ho fihlela ho lefela, e leng ntho ea bohlokoa bakeng sa ho fihlela litekanyetso tsa polokeho ea tikoloho.

Meriana: Li-diaphragm tsa PTFE tse ka har'a li-valve tse se nang likokoana-hloko li thibela ho khomarela ha likokoana-hloko, e leng ntho ea bohlokoa bakeng sa ho latela melao ea GMP le FDA.

Matla le Kalafo ea Metsi: Li-valve tsa serurubele tse koetsoeng ka PTFE lits'ebetsong tsa ho pholisa li hanela ho hola le ho pepesehela chlorine, e leng se fokotsang tahlehelo ea matla ho tsoa ho khanyetso ea phallo ka 30%.

Tlhahiso ea Semiconductor: Likarolo tsa PTFE tse hloekileng haholo li thibela tšilafalo ea ionic lits'ebetsong tsa phepelo ea metsi le khase tse hloekileng haholo.

6. Mekhoa ea Nakong e Tlang: Kopanyo e Bohlale ea PTFE le Botsitso​

Karolo ea PTFE e ntse e tsoela pele ho fetoha ka litlhoko tsa indasteri:

Metswako ea PTFE e Tsitsitseng: Metswako ea PTFE e sebelisitsoeng hape e boloka 90% ea ts'ebetso ea thepa e sa tsoakoang ha ka nako e ts'oanang e fokotsa tšusumetso ea tikoloho.

Li-valve tse Buloang ke IoT: Li-sensor tse kentsoeng ka har'a litiiso tsa PTFE li hlokomela ho tsofala le ho lutla ha motlakase ka nako ea sebele, e leng se nolofalletsang tlhokomelo e boletsoeng esale pele le ho fokotsa nako ea ho phomola e sa reroang.

Lisebelisoa tse kopantsoeng: Metswako ea PTFE-PEEK bakeng sa maemo a feteletseng (mohlala, li-valve tsa nyutlelie) e kopanya setlolo le matla a mechini, e leng se sutumelletsang meeli ea khatello le meeli ea mocheso.

7. Qetello​

PTFE e phahamisitse theknoloji ea li-valve ka ho rarolla liphephetso tsa nako e telele tsa ho bola, khohlano le taolo ea mocheso. Ho kopanngoa ha eona le litiiso, li-linings le likarolo tsa ho roala ho netefatsa ts'epahalo ho pholletsa le liindasteri tse fapaneng, ho tloha lifemeng tsa lik'hemik'hale ho ea ho masela a semiconductor. Ha saense ea thepa e ntse e tsoela pele, PTFE e tla tsoela pele ho nolofalletsa litharollo tsa li-valve tse bobebe, tse sebetsang hantle le tse tšoarellang nako e telele tse lumellanang le mekhoa ea lefats'e ea ho its'ireletsa le ho fetoha ha dijithale.

Theknoloji ea Ningbo Yokey Precision e sebelisa boiphihlelo ba ho kopanya PTFE ho nts'etsapele litiiso tse ikhethileng le likarolo tsa li-valve bakeng sa lits'ebetso tsa likoloi, matla le indasteri. Litifikeiti tsa rona tsa IATF 16949 le ISO 14001 li netefatsa boleng bo tsitsitseng libakeng tse nang le likotsi tse kholo.

Mantsoe a bohlokoa: Li-valve tsa PTFE, ho tiisoa ha fluoropolymer, ho hanyetsa lik'hemik'hale, taolo ea mokelikeli oa indasteri
