Xana ku lwisana na creep na ku tiya ka nkarhi woleha ka ku khoma ka thepi ya high-hold Teflon high-temperature swinga antswisiwa njhani?

I.Topology ya Netiweke ya MolekhuliKu Antswisiwa kaLeyara ya Xinamarheti xa Silicone–Ku Antswisa Ku Lwisana ka BulkCreep

1.HighMQResin / SiliconeRubberRationa 'Xivumbeko xa Hard-Core '

Vaendli va tekela MQsiliconere tani hicoretackifier naku sindzisa, ku engetela MQ/gumratioto1.2:1–2:1(hindlela yale henhla swinene kutlula tigredi ta ntolovelo).ThishighMQratioformcontinuous rigid'hard-phase'microdomainthintheadhesive layer,leyi yi sivelaka ku famba ka siloxanechainsegments naswona yi antswisa swinene modyuli ya vuhlayiselo naswona yi cree ku lwisana na mahiselo lama tlakukeke.

2.Ku nghenisiwa ka Mintlawa yo tiya leyi nga tiyiseliki ku hisa na Tindhawu to Hlanganisa ta Eneji ya le Henhla ya Bond

Phenyl,diphenyl,kumbe mintlawa ya khaborani yi nghenisiwa eka polydimethylsiloxanebackbone(xikombiso,20–30mol%phenylcontent)ku sivela ku famba ka thermalchain naku tlakusa havumbirhi bya mahiselo ya ntshamiseko wa nghilazi na rmaldecompositiontemperature.Sisiteme yo hlanganisa hi ku tsakela ku tirhisa ku engetela-ku horisa hydrosilylation(Pt-catalyzed),ku vumba–C–C–kumbe–Si–C–buloho ro hlanganisa na ku tshamiseka ka le henhla kumbe ku hisa.

3.Vulawuri bya Ndzilo wa MolekhuliExikarhi ka Swihlanganisi swa Xihambano(Mc) na Swihoxo swa Netiweke

Hi ku lulamisa kahle nhundzu ya hayidirojeni leyi tirhaka na ku leha ka nketani ya siliconeoil leyi nga na hayidirojeni,Mc leyi fanaka swinene (kwalomu ka 5,000–15,000g/mol) yi fikeleriwile, ku tiyisisa leswaku nete ntirho wu hlayisa ku tiyisela lokukulu eka mahiselo ya le henhla.Ku andlariwa ka le ndzhaku ka ku horisa kumbe mahiselo ya le henhla ku tirhisiwa eka mintlawa ya ku angula leyi saleke ya vatirhisi na ku hunguta ku ntshunxeka ka ntshikilelo loku vangiwaka hi swihoxo swa netiweke.

III.NanofillersforKu Aka Ku Hlanganisa ka Ximiri na Marhambu lama Tiyiselaka ku Hisa

1.Ku Tiyisisiwa ka Ndhawu na ku Cinca ka le Henhla ka Nano-Silica

Vaendli va tirhisa fumedsilica(ndhawu yo karhi ya le henhla ya200–380m²/g), leyi tshunguriweke ehenhla hi vinyltriethoxysilaneorhexamethyldisilazane, ku layicha ka 10–25wt%.Thenano-SiO2 yi vumba swiboho swa hayidirojeni na ku hlanganisiwa ka nyama hi tikheteni ta siloxane, ku tumbuluxa reversiblephysicalcrosslinkingnetwork leyi hangalasaka eneji na ku sivela tikhetane ta timolekhuli ku rhelela eka matluka eka mahiselo yo leha.Ku hangalaka ka xirhendzevutani xa le henhla ku tiyisisa leswaku silika yi kona'ti-cluster' leti nga na vukulu bya tigglomerates ehansi ka 100nm, ku papalata ku hlangana ka ntshikilelo.

2.DirectionalCreepResistance hi ku tirhisa2DNanomaterials

Ku engeteriwa ka1–5wt%few-layergraphenekumbe organic-modifiednano-montmorillonite, leyi kongomisiweke eka layeredarrangement hi ku tirhisa ku ringanisa loku hlohloteriweke hi ku tsemeta hi nkarhi wa ku peta, swi vumba 'mazeeffect'paralleltothetapep lane,ku engetela swinene ku lwisana eka nsusumeto wa timolekhuli eka tlhelo ro tsemeka.Tigirapheni ti na ku fambisa ku hisa lokunene, ku hunguta tindhawu to hisa eka leyara yo namarhela na ku veka ku olova ka ku hisa.

IV.Nhlanganiso wa TikhemikhaliSubstrate–AdhesiveInterface na Vulawuri bya Maendlelo

1.Ku Tirhisa ka le Henhla naPrimer ya Ntirho wa Vumbirhi eka ku Boha ka Tikhemikhali

Vuandlalo bya PTFE byi rhanga byi tshunguriwa hi sodium–naphthalene–THFsolution kumbe argon/oxygenplasma ya ntshikelelo wa le hansi ku tumbuluxa leyara leyi tirhisiweke leyi nga na mintlawa ya carboxylandhydroxyl.Aprimersolution leyi nga na timolekhuli leti tirhaka timbirhi(xikombiso, isocyanatesilane,titanatecouplingent+epoxysilane)xi kona hi xihatla ated.Un’we eka primerreactwith–OH/–COOHonthePTFEsurface,loko yin’wana yi hetelela yi nghenelela eka hydrosilylation kumbe condensation crosslinking na siliconeadhesive, yi vumba netiweke ya tikhemikhali leyi nghenaka eka interface.Ndlela leyi yi nga engetela matimba yo khoma mahiselo ya le henhla(eka260°C) hi minkarhi ya 3–5.

2.RampedCuringandPost-Treatmentku Herisa Swihoxo

Arampedcuringprofile yi tirhisiwile:xo sungula, swintshuxo swi fambisiwa na leyara ya swinamarheti swi levhele eka80–100°C;kutani hydrosilylation na ku pakiwa ka MQresina swi hetisiwile eka150–170°C;eku heteleleni,post -ku horisa ku nghenisiwa ehandle eka200–220°Cku ringana tiawara to hlaya ku herisa ntshikilelo wa le ndzeni na ku tiyisisa tindhawu to hlanganisa ta miri.Ku kufumela hi ku nonoka swi sivela ku pandzeka lokutsongo hikwalaho ka ku hunguteka ka ku hisa loku hambaneke.
