Tanihi muendli lonkulu wa PTFE coated lapi na switirhisiwa leswi fambelanaka na swona, Jiangsu Aokai New Materials Technology Co., Ltd. yi ku tisela vutivi bya xiphurofexinali. While fiberglass cloth remains the most common base material for PTFE impregnation , swin’wana swotala swa substrates swikona – yin’wana na yin’wana yinyika swivumbeko swo hlawuleka eka switirhisiwa swokarhi swa matirhelo yale henhla.
Laha hansi hi lavisisa 7 wa ti substrates tin’wana, swihlawulekisi swa maendlelo ya tona, swipfuno, na swipimelo.
Fibre ya Aramid (xikombiso, Kevlar®) .
Endlelo: Yi lukiwa eka malapi kumbe swivumbeko swa ti tubular, kutani yi cheriwa PTFE.
Swipfuno: Matimba yale henhla swinene ya ku tsana, ku tiya swinene ka ku onhaka, ku sivela malangavi, na ku nga tirhi ka tikhemikhali. Yi hlanganisa matimba yale henhla na ku olova eka ku cheriwa ka mafurha lawa yangariki na oyili.
Switirhisiwa: Swipaci swa ti valve ta ntshikelelo wa le henhla, swiphemu swa aerospace, switirhisiwa swo sirhelela leswi nga ngheniwiki hi swibalesa.
Swipimelo: Ntsengo wa le henhla swinene ku tlula fiberglass; ku lwisana lokunene ka UV.
Fibre ya Khaboni
Endlelo: Ngopfu ngopfu yi endliwa kuva yiva braided packing, kutani yi cheriwa PTFE.
Swipfuno: Matimba yale henhla, modulus yale henhla, conductivity yale henhla ya thermal (yi papalata ku hlengeletiwa ka kuhisa), thermal expansion coefficient yale hansi.
Switirhisiwa: Swiyimo swotala swinene – mahiselo yale henhla, ntshikelelo wale henhla, rivilo rale henhla; switirhisiwa swo endla ti semiconductor.
Swipimelo: Ntsengo wa le henhla wa vuhumelerisi; friction coefficient yale henhla swinene (yi antswisiwile endzhaku ka PTFE coating); hi ntumbuluko yi fambisa – yi lava vutshunguri bya insulation eka swiyimo swin’wana.
PBI (Polybenzimidazole) Xiphemu xa fibre
Endlelo: Yi lukiwa eka swivumbeko swa ti tubular, kutani yi cheriwa PTFE emulsion kutani yi sintered.
Swipfuno: Ku tiya ka mahiselo yale henhla swinene – swihlayisa swivumbeko swa michini xikan’we naku tiya ka ku ambala ehenhla ka 400°C.
Switirhisiwa: Nsirhelelo wo tika wa mahiselo yale henhla na ku pfariwa eka tiindasitiri ta swihahampfhuka na masocha.
Swipimelo: Ku durha lokukulu swinene; ku tshamiseka loku nga nyawuriki eka tindhawu ta aerobic ta mahiselo ya le henhla; swi lulamerile ntsena eka tinsimu ta niche.
PBI fibre yikombisa kutshamiseka ka mahiselo yo hlawuleka – eka ndzhawu hinkwayo ya mahiselo ya yona yo pima, modulus yosungula ya fibre yitshama yirikarhi yi cinca cinca. Eka tindzhawu letinga inert gas kumbe vacuum, hambi endzhaku ka 300 wa tiawara eka 350°C, kungari na mbuyelo lowukulu wa ku dyuhala lowu humelelaka. Loko ti PBI fibre tubes ti cheriwa PTFE emulsion hiku tirhisa maendlelo ya switeji swotala (ku nyuperisa, ku omisa, ku baka, naku sintering), anti-wear liner leyi humelelaka yinga tiyisela mahiselo lawa ya yaka emahlweni ya ntirho ya 290°C, ku hlangana hi xihatla kuya fika eka 500°C, na ku lahlekeriwa hi ntiko ehansi ka 5% eka 315°C loko yirikarhi yi hlayisa ku tiya ka kahle swinene ka ku onhaka. Eka switirhisiwa swofana na ti clamps ta njhini ya swihahampfhuka, switirhisiwa swa ndhavuko swofana na EPDM, nitrile rubber, fabric-reinforced silicone rubber, na standard PTFE aswinga fikeleli swilaveko leswi – ti PBI/PTFE composites ti tlhantlha timhaka ta ku lwisana na mahiselo yale henhla na ku onhaka, leswi ndlandlamuxaka swinene ku koteka ka matirhiselo.
Nsimbi ya Porous
Endlelo: PTFE dispersion liquid yi nghena eka ti pores ta nsimbi hiku tirhisa vacuum impregnation, leswi landzeriwaka hi high‐temperature sintering.
Swipfuno: Yi hlanganisa matimba ya michini ya nsimbi na ku tiya ka dimensional na self‐lubricity ya PTFE na ku lwisana na corrosion.
Switirhisiwa: Tibeyari leti ti tota, ti piston rings, ti guide rails, na swiphemu swin’wana swa michini.
Swipimelo: Swilaveko swo tika eka porosity ya nsimbi na ku hangalasiwa ka vukulu bya pore ku tiyisisa ku cheriwa loku faneleke ka PTFE.
Graphite leyi nga ni swiphemuphemu
Endlelo: PTFE yi tata ti pores ta le ndzeni ta graphite hiku tirhisa impregnation leyi tinyiketeleke na vutshunguri bya plasticizing.
Swipfuno: Yi vumba graphite leyi nga nghenekiki leyi nga na ku tiya ka kahle swinene eka ku bola – yi tirhisiwa eka ti khemikhali leti cincaka ku hisa na ti reactor liners. Nakambe yitirhisiwa ngopfu eka ti gaskets to pfalela ta mahiselo yale henhla.
Swipimelo: Graphite yi brittle; vulawuri byo tika lebyi lavekaka ku tiyisisa ku cheriwa loku fanaka na ku hlanganisiwa loku tiyeke ka interfacial.
Asbestos (Xitirhisiwa xa Ndzhaka) .
Endlelo: Xitirhisiwa xa ndhavuko xa impregnation; tifibre ta asbestos leti cheriweke PTFE ku luka swiphemu swo pfalela leswi cinca-cincaka.
Swipfuno: Khale yi amukeriwile ngopfu eka tinsimu to hambana hambana to pfalela.
Swipimelo: Yi hlayiwa tani hi carcinogen – yi herisiwa hi swiyenge kumbe yi siveriwa swinene eka tindzhawu totala, hakatsongotsongo yi siviwa hi ti aramid fibers.
Swilo swo Tata swa Ceramic
Endlelo: Yi hlanganisiwa hiku hetiseka na PTFE emulsion kuva yi endla composite slurry, kutani yitirhisiwa ku chela ti reinforcing substrates kufana na fiberglass cloth.
Swipfuno: Yi lulamisa kahle dielectric constant na dielectric loss – swa nkoka eka high‐frequency, high‐speed copper clad laminates.
Switirhisiwa: Elektroniki – Switirhisiwa swa PCB swa vuhlanganisi bya 5G na frequency ya le henhla.
Swipimelo: Vulawuri bya maendlelo lebyi rharhanganeke; swi lava ku hangalasiwa ka filler leyi fanaka eka PTFE.
Mahetelelo – Hlawula Substrate leyi Faneleke eka Swilaveko swa Wena
Loko lapi ra fiberglass ri tshama riri hanci ya ntirho eka vuhumelerisi bya malapi lawa ya pfanganisiweke na PTFE , swin’wana swofana na aramid, carbon fibre, porous metal, na graphite swinyika swipfuno swo hlawuleka eka swiyimo swo tika swinene – kusuka eka aerospace kuya eka vumaki bya semiconductor.
Loko u hlawula substrate ya PTFE impregnation , anakanya hi:
Mahiselo yo tirha na mbango
Swilaveko swa matimba ya michini na ku ambala
