Tsab ntawv xov xwm no suav nrog cov ntsuas kev ua haujlwm tseem ceeb rau PTFE cov kab xev kub kub siv hauv lub tshuab nqus tsev, lub tshuab nqus tsev kho cua sov thiab cov chaw zoo sib xws. Cov kev cai tseem ceeb sib txawv heev ntawm kev siv atmospheric: outgassing yog qhov tseem ceeb tshaj plaws (TML≤1%, CVCM≤0.1%; aerospace / optical qib yuav tsum TML≤0.5%, CVCM≤0.01%); Qhov kub thiab txias yuav tsum tau kuaj xyuas rau ob qho tib si PTFE substrate (260 ° C) thiab nplaum txheej; tshwj xeeb purified low-outgassing silicone PSA yuav tsum tau tiv thaiv siloxane paug; high-temperature tuav lub zog tiv thaiv creep thiab ntug lifting; huv si xav tsis muaj fiber ntau los thiab cov ntsiab lus ionic tsawg; anti-static daim kab xev (nto resistivity 10⁶-10⁹ Ω / sq) tiv thaiv ESD kev puas tsuaj; plasma kuj yuav tsum raug soj ntsuam rau cov txheej txheem sputtering / PECVD; thermal shrinkage qis dua 2% ua kom cov npog qhov tseeb.

Kab lus no piv rau chav kub thiab kub kub kom loj hlob ntawm silicone siab-rhiab nplaum nplaum rau PTFE daim kab xev. Kub-kub maturation (120-180 ° C) tsim dense crosslinked tes hauj lwm nrog muaj zog cohesive zog, tiv thaiv cov nplaum residue tom qab tev. Nws tsim cov tshuaj anchoring bonds nrog PTFE substrates ntawm primer co-curing, tshem tawm delamination txaus ntshai. High-temperature maturation kuj tshem tawm cov tsis tshua muaj molecular volatiles ua ntej xa khoom, tiv thaiv bubbling thiab silicone roj paug thaum thawj cua sov.

Daim ntawv qhia no npog PTFE high-temperature daim kab xev xaiv rau kev txhaj tshuaj molding demolding thiab anti-stick daim ntaub ntawv. Kev xaiv kub raws li: ≤260 ° C rau cov yas dav dav (tus qauv silicone PSA daim kab xev, 0.13-0.18mm); 260-300 ° C rau high-temperature engineering yas xws li PC, PA66, POM (high-temp silicone nplaum, 0.18-0.25mm); 300-400 ° C rau PEEK, LCP, PPS nyob ze cov neeg ua haujlwm kub (cov nplaum nplaum tsis ua haujlwm; siv cov ntaub nplaum tsis muaj PTFE lossis PFA zaj duab xis). Cov khoom siv raws li kev xaiv: tacky cov ntaub ntawv xav tau siab tso tawm ntshiab PTFE nto; iav / ntxhia ntim cov ntaub ntawv yuav tsum tau ua haujlwm hnyav 0.25mm + hnav-resistant daim kab xev; corrosive additives xav tau chemically resistant nplaum thiab ntom substrate; static-sensitive daim ntaub ntawv yuav tsum tau anti-static dub PTFE daim kab xev.

PTFE-coated fiberglass daim ntaub yog dav siv nyob rau hauv cov roj hmab ua rau nws cov cua kub tsis kam, tsis-stick khoom, thiab tsis muaj kev sib txhuam. Cov ntawv thov tseem ceeb muaj xws li: tso cov ntaub ntawv rau lub phaj / lub tshuab nqus tsev vacuum thiab lub log molding; tsis-stick conveyor siv rau qhib mills, calenders, thiab txias kab; interleave ntaub rau semi-tiav roj hmab cia; tshwj xeeb tuav ntawm silicone thiab fluororubber; thiab cov tais diav rau tom qab kho. Cov txiaj ntsig muaj xws li tshem tawm cov pwm adhesion, txo cov neeg siv kev tso tawm, tiv thaiv cov menyuam qhwv, thiab ua kom du demolding.

Cov iav hloov pauv kub (Tg) ntawm silicone siab-rhiab nplaum nplaum yog nyob ib ncig ntawm -120 ° C - qis dua li acrylic nplaum. Qhov no ultra-low Tg khaws PTFE high-temperature daim kab xev hloov tau yooj yim thiab nplaum txawm nyob rau ntawm -70 ° C, tiv thaiv nkig tawg thiab ua kom muaj kev ruaj ntseg adhesion hauv cov ntawv thov cryogenic.

Kev xaiv ntawm cov ntawv tso tawm lossis zaj duab xis substrate thiab tso tawm tus neeg sawv cev ncaj qha cuam tshuam rau kev ruaj khov thiab kev ua haujlwm ntawm PTFE cov kab xev kub kub. Kab lus no sib piv PET vs. kraft daim ntawv substrates thiab silicone vs. fluorinated tso cov neeg ua haujlwm, pom zoo ua ke kom zoo rau xoom-residue tev thiab kev ntseeg tau ntev.
