Ki jan yo ka amelyore rezistans ranpe ak estabilite kenbe alontèm nan kasèt Tflon wo-tanperati ki wo?

I. Topoloji Molekilè RezoOptimizasyon Kouch Adezif Silisyòm lan-Amelyore Rezistans Deplasman Bulk

1.HighMQResin/SiliconeRubberRatioand'Hard-Core'Estrikti

Manifakti a adopte MQ silikone kòm ajan takè ak ranfòsman, ogmante rapò MQ/gonm a 1.2:1–2:1 (siyifikativman pi wo pase klas konvansyonèl yo). rijid 'difisil-faz'microdomainswithintheadhesivelayer, ki contraintethemovementofsiloxanechainsegmentsandsubstantially improvethestoragemodulsandcreepresistanceandcreepresistanceandelevatedtemperatus.

2.IncorporationofHeat-Resistant RigidGroupsand High-Bond-Energy Crosslinking Sites

Fenil, difenil, oswa gwoup kabòn yo prezante nan zo rèldo polidimetilsiloksan (egzanp, 20-30 mol% kontni fenil) pou anpeche mouvman chèn tèmik epi ogmante tou de tanperati tranzisyon vè a ak tanperati a. rmaldecompositiontemperature.Thecrosslinkingsystempreferentiallyemploysaddition-curehydrosilylation(Pt-catalyzed),forming–C–C–or–Si–C–crosslinkingbridgeswithsuperiorthermalstability.

3.Kontwole PwaMolekilè Ant Lyen Transversal (Mc) ak Defo Rezo

Lè yo ajiste avèk presizyon kontni idwojèn aktif ak longè chèn nan lwil oliv silikon ki gen idwojèn, se relativman ti inifòm Mc (apeprè 5,000-15,000g/mol) reyalize, asire ke rezo a. travay kenbe gwo rezilyans menm tanperati.Pos-geri pwolonje oswa gwo-tanperati renkwire ap aplike nan gwoup reyaktif konsomatè ak diminye detant estrès ki te koze pa defo rezo a.

IV.Substrate Entegre Chimik–Entèfas Adezif ak Kontwòl Pwosesis

1.SurfaceActivationandBifunctionalPrimerforChemicalBonding

Sifas PTFE a an premye trete ak solisyon asodyòm-naftalèn-THFoswa-agon/oksijènplasmatojenere yon kouch aktive ki gen gwoup karboksi ak idroksil. ated.Youn nan premye a reyaji avèk–OH/–COOHsou sifas PTFE,pandan ke lòt la patisipe nan retikulasyon idrosililasyon oswa kondansasyon ak adezif silikon, fòme yon rezo lyezon chimik ki antre nan koòdone.
