Daim ntaub ntawv: Cov khoom siv siab siab valve, cov khoom siv hauv aerospace, cov ntaub ntawv tiv thaiv mos txwv.
Kev txwv: Tus nqi ntau dua li fiberglass; tsis zoo UV tsis kam.
Carbon Fiber ntau
Txheej txheem: Feem ntau ua rau hauv braided packing, ces impregnated nrog PTFE.
Qhov zoo: siab zog, siab modulus, superior thermal conductivity (tsis txhob tshav kub sib sau), tsawg thermal expansion coefficient.
Daim ntaub ntawv: Cov xwm txheej hnyav - kub siab, siab siab, siab ceev; semiconductor manufacturing khoom.
Kev txwv: Cov nqi tsim khoom siab; kuj muaj kev sib txhuam coefficient (zoo tom qab PTFE txheej); inherently conductive - xav tau kev kho rwb thaiv tsev hauv qee qhov xwm txheej.
PBI (Polybenzimidazole) Fiber ntau
Txheej txheem: Woven rau hauv tubular qauv, ces impregnated nrog PTFE emulsion thiab sintered.
Qhov zoo: Qhov zoo tshaj plaws-kub tsis kam - tswj cov khoom siv kho tshuab thiab hnav tsis kam tshaj 400 ° C.
Daim ntawv thov: nruj tiv thaiv kub thiab sealing hauv aerospace thiab tub rog kev lag luam.
Kev txwv: Tus nqi siab heev; txwv stability nyob rau hauv high-kub aerobic ib puag ncig; tsuas yog haum rau niche teb.
PBI fiber ntau nthuav tawm qhov tshwj xeeb thermal stability - thoob plaws hauv nws qhov ntsuas qhov ntsuas kub, cov fiber ntau qhov pib modulus tseem nyob tas li. Hauv qhov chaw tsis muaj roj lossis lub tshuab nqus tsev, txawm tias tom qab 300 teev ntawm 350 ° C, tsis muaj qhov cuam tshuam loj rau kev laus. Thaum PBI fiber tubes impregnated nrog PTFE emulsion los ntawm ntau theem txheej txheem (dipping, ziab, ci, thiab sintering), qhov tshwm sim los tiv thaiv hnav liner tuaj yeem tiv taus qhov kub thiab txias ntawm 290 ° C, instantaneous raug mus txog 500 ° C, nrog yuag poob qis dua 5% ntawm 315 ° C thaum tswj kev hnav zoo heev. Rau cov ntaub ntawv xws li aircraft cav clamps, ib txwm siv xws li EPDM, nitrile roj hmab, ntaub-reinforced silicone roj hmab, thiab txheem PTFE tsis tuaj yeem ua tau raws li cov kev cai no - PBI / PTFE composites daws ob qho tib si kub-kub thiab hnav teeb meem, nthuav dav daim ntawv thov muaj peev xwm.
Txheej txheem: PTFE dispersion kua nkag mus rau hlau pores ntawm lub tshuab nqus tsev impregnation, ua raws li los ntawm high-temperature sintering.
Qhov zoo: Ua ke hlau lub zog txhua yam thiab qhov ruaj khov nrog PTFE tus kheej lubricity thiab corrosion kuj.
Daim ntaub ntawv: Self-lubricating bearings, piston rings, coj rails, thiab lwm yam mechanical qhov chaw.
Cov kev txwv: nruj me ntsis ntawm cov hlau porosity thiab pore loj faib los xyuas kom meej PTFE impregnation.
Porous Graphite
Txheej txheem: PTFE sau nrog graphite pores ntawm nplooj siab impregnation thiab kho plasticizing.
Qhov zoo: Cov ntaub ntawv impermeable graphite nrog zoo heev corrosion kuj - siv nyob rau hauv tshuaj kub exchangers thiab reactor liners. Kuj dav siv nyob rau hauv high-temperature sealing gaskets.
Daim ntaub ntawv: Cov khoom siv tshuaj ua haujlwm, cov ntsaws ruaj ruaj kub.
Kev txwv: Graphite yog nkig; Kev tswj nruj yuav tsum tau ua kom ntseeg tau tias tsis sib xws impregnation thiab muaj zog interfacial bonding.
Asbestos (Legacy Substrate)
Txheej txheem: tsoos impregnation substrate; asbestos fibers impregnated nrog PTFE rau weave dynamic sealing qhov chaw.
Qhov zoo: Ib zaug siv dav hauv ntau yam kev sib khi.
Kev txwv: Muab cais raws li cov carcinogen - phased tawm los yog nruj me ntsis txwv nyob rau hauv feem ntau cov cheeb tsam, maj mam hloov los ntawm aramid fibers.
Ceramic Fillers
Txheej txheem: Sib tov tag nrho nrog PTFE emulsion los tsim cov slurry sib xyaw, ces siv los impregnate reinforcing substrates zoo li fiberglass daim ntaub.
Qhov zoo: Precisely adjusts dielectric tas li thiab dielectric poob - qhov tseem ceeb rau high-frequency, high-ceev tooj liab clad laminates.
Daim ntawv thov: Electronics - PCB substrates rau 5G thiab kev sib txuas lus siab.
Kev txwv: kev tswj cov txheej txheem nyuaj; yuav tsum tau muab tub lim dispersion nyob rau hauv PTFE.
Xaus - Xaiv txoj cai substrate rau koj xav tau Thaum fiberglass daim ntaub tseem ua haujlwm rau PTFE coated npuag ntau lawm, lwm yam zoo li aramid, carbon fiber, ntxeem tau hlau, thiab graphite muab tshwj xeeb zoo rau huab cua - los ntawm aerospace mus rau semiconductor manufacturing.
