Cov khoom sau daws cov teeb meem no los ntawm kev ua raws li cov pob txha txhawb nqa hauv PTFE matrix, txhim kho kev tiv thaiv creep, kev kam rau siab hnav, thiab thermal conductivity yam tsis muaj kev cuam tshuam nws cov txiaj ntsig tseem ceeb.

2. Cov Iav Fiber: Tus Txhim Kho Uas Pheej Yig

Cov Khoom Tseem Ceeb

Kev Hnav Tsis kam: Cov iav fiber (GF) txo cov PTFE txoj kev hnav tsis kam txog li 500 zaug, ua rau nws zoo tagnrho rau cov chaw muaj kev thauj khoom ntau.

Kev Txo Qhov Ntsug: GF ua rau kom muaj kev ruaj khov ntawm qhov ntev, txo qhov deformation nyob rau hauv kev ntxhov siab tas mus li.

Cov Kev Txwv Thermal thiab Tshuaj Lom Zem: GF ua tau zoo hauv qhov kub txog li 400 ° C tab sis lwj hauv hydrofluoric acid lossis cov hauv paus muaj zog.

Cov ntawv thov

PTFE uas muaj GF-reinforced feem ntau siv rau hauv cov hydraulic seals, pneumatic cylinders, thiab industrial gaskets uas muaj zog thiab kev siv nyiaj tsawg. Nws qhov sib xws nrog cov additives xws li MoS₂ ua rau kev tswj kev sib txhuam zoo dua.

3. Carbon Fiber: Kev Xaiv Ua Tau Zoo

Cov Khoom Tseem Ceeb

Lub Zog thiab Kev Ruaj Khoov: Cov roj carbon fiber (CF) muaj lub zog tensile zoo dua thiab flexural modulus, xav tau cov ntim khoom qis dua li GF kom ua tiav cov khoom txhawb nqa zoo sib xws.

Kev Ua Haujlwm Thermal: CF txhim kho cov cua sov dissipation, tseem ceeb rau cov ntawv thov ceev ceev.

Kev Tsis Muaj Tshuaj Lom Zem: CF tiv taus cov kua qaub muaj zog (tshwj tsis yog cov oxidizers) thiab tsim nyog rau cov chaw muaj tshuaj lom neeg hnyav.

Cov ntawv thov

CF-PTFE composites zoo heev hauv cov khoom siv absorbers hauv tsheb, cov khoom siv semiconductor, thiab cov khoom siv aerospace, qhov twg qhov hnyav thiab kev tswj hwm thermal yog qhov tseem ceeb.

4. Graphite: Tus Kws Tshwj Xeeb Txog Kev Siv Lubrication

Cov Khoom Tseem Ceeb

Kev Sib Txhuam Qis: PTFE uas muaj Graphite ua tiav cov coefficients sib txhuam tsawg li 0.02, txo qhov poob zog hauv cov kab ke dynamic.

Kev Ruaj Ntseg Thermal: Graphite ua rau kom muaj kev ua haujlwm ntawm cov thermal conductivity, tiv thaiv kev kub hnyiab hauv cov neeg sib cuag ceev ceev.

Kev Sib Tw Mos-Mating: Nws txo qhov hnav tawm tsam cov chaw mos xws li txhuas lossis tooj liab.

Cov ntawv thov

Cov khoom sib xyaw ua los ntawm graphite yog qhov nyiam siv rau hauv cov bearings uas tsis muaj lubricated, compressor seals, thiab cov tshuab tig uas qhov kev ua haujlwm du thiab kev tso cua sov tawm yog qhov tseem ceeb.

5. Kev Txheeb Xyuas Piv Txwv: Xaiv Cov Khoom Siv Sau Kom Yog

Cov tshuaj sib xyaw ua ke

Kev sib xyaw ua ke ntawm cov khoom sib xyaw - piv txwv li, iav fiber nrog MoS₂ lossis carbon fiber nrog graphite - tuaj yeem ua kom zoo dua ntau yam khoom. Piv txwv li, GF-MoS₂ hybrids txo qhov kev sib txhuam thaum tswj kev hnav tsis kam.

6. Cov Kev Cuam Tshuam rau Kev Lag Luam thiab Kev Ruaj Ntseg

Cov PTFE composites uas muaj cov khoom sib xyaw ua ke ua rau lub neej ntawm cov khoom siv ntev dua, txo qhov zaus kho, thiab txhim kho kev siv hluav taws xob zoo dua. Piv txwv li, cov foob graphite-PTFE hauv LNG systems tiv taus qhov kub ntawm -180 ° C txog + 250 ° C, ua tau zoo dua li cov khoom siv ib txwm muaj. Cov kev nce qib no sib haum nrog cov hom phiaj kev lag luam ncig los ntawm kev txo cov khib nyiab los ntawm kev tsim qauv ruaj khov.

Xaus lus

Qhov kev xaiv ntawm cov khoom siv ntxiv—iav fiber, carbon fiber, lossis graphite—ua rau PTFE composites muaj kev ua tau zoo. Txawm hais tias iav fiber muaj tus nqi sib npaug thiab ruaj khov, carbon fiber zoo tshaj plaws hauv cov xwm txheej hnyav, thiab graphite muab qhov tseem ceeb rau kev ua kom lubrication. Kev nkag siab txog qhov sib txawv no ua rau cov engineers tuaj yeem kho cov kev daws teeb meem sealing kom ntseeg tau thiab ua haujlwm tau zoo.

Thaum cov lag luam hloov zuj zus mus rau cov qauv kev ua haujlwm siab dua, kev koom tes nrog cov kws tshaj lij hauv kev tshawb fawb txog cov khoom siv ua kom muaj kev tsim khoom zoo tshaj plaws. Ningbo Yokey Precision Technology siv cov kev txawj ntse siab heev los xa cov foob pob uas ua tau raws li cov kev cai nruj rau kev siv tsheb, lub zog, thiab kev siv hauv kev lag luam.
