O lenei tusiga o loʻo aofia ai faʻataʻitaʻiga autu o faʻatinoga mo le PTFE maualuga-vevela lipine faʻaaogaina i le faʻapipiʻiina o le masini, togafitiga vevela vevela ma siosiomaga tutusa. Mana'oga autu e matua'i ese lava mai le fa'aogaina o le ea: e sili ona taua le fa'aogaina o kasa (TML≤1%, CVCM≤0.1%; va'alele/va'aiga mata'utia mana'omia TML≤0.5%, CVCM≤0.01%); e tatau ona fa'amaonia le tete'e o le vevela mo mea uma e lua o le PTFE (260°C) ma le fa'apipi'i; e mana'omia le PSA silikoni fa'amama fa'apitoa e puipuia ai le fa'aleagaina o le siloxane; o le malosi o le taofiofi o le vevela maualuga e taofia ai le fetolofi ma le siiina o pito; O le mama e le mana'omia ai le fa'amaligiina o alava ma le maualalo o mea ionic; lipine fa'aanti-static (fa'asagaga i luga ole 10⁶-10⁹ Ω/sq) e taofia ai le fa'aleagaina o le ESD; plasma tetee e tatau ona iloiloina mo sputtering/PECVD faiga; fa'aitiitiga vevela i lalo ole 2% fa'amautinoa le sa'o o le masking.

O lenei tusiga e faʻatusatusa ai le vevela o le potu ma le maualuga o le vevela o le faʻapipiʻi faʻapipiʻi silikoni mo le lipine PTFE. O le matua maualuga o le vevela (120-180°C) e fa'atupuina ai feso'ota'iga mafiafia e feso'ota'i fa'atasi ma le malosi malosi fa'atasi, e puipuia ai le to'ega pipii pe a uma ona pa'u. E fa'atūina fa'amauga fa'a vaila'au fa'atasi ma substrate PTFE e ala ile fa'amalo fa'atasi muamua, fa'ate'a ai a'afiaga fa'aletonu. O le matua maualuga o le vevela e aveese ai foʻi mea maualalo mole mole aʻo leʻi tuʻuina atu, puipuia ai le faʻafefe ma le faʻaleagaina o le suauʻu silicone i le taimi muamua o le faʻamafanafanaina.

O lenei ta'iala o lo'o aofia ai le filifilia o lipine fa'amaumau maualuga a le PTFE mo le fa'aogaina o le tui fa'alia ma le fa'aogaina o le fa'ato'aga. Filifiliga faʻavae vevela: ≤260 ° C mo palasitika lautele (silikoni PSA masani, 0.13-0.18mm); 260-300 ° C mo palasitika inisinia maualuga-vevela pei PC, PA66, POM (maualuga silicone pipii, 0.18-0.25mm); 300-400°C mo PEEK, LCP, PPS latalata i tamo'e vevela (fa'apipi'i fa'apipi'i le manuia; fa'aoga ie PTFE e leai se pipii po'o le ata PFA). Filifiliga fa'avae: mea tacky mana'omia maualuga-fa'asa'oloto luga PTFE mama; tioata / minerale fa'atumu mea e mana'omia le mamafa-tiute 0.25mm + fa'amaufa'aisa lipine; mea fa'apipi'i fa'ama'i e mana'omia se mea fa'apipi'i fa'ama'i ma mea mafiafia; talosaga ma'ale'ale mana'omia anti-static lipine PTFE uliuli.

PTFE-coated fiberglass ie e masani ona faʻaaogaina i le faʻaogaina o le paʻu mo lona faʻafefe vevela, mea e le faʻapipiʻi, ma le maualalo o feteʻenaʻiga. Talosaga autu e aofia ai: fa'asa'oloto laina mo ipu/vacuum vulcanization ma pa'u lilia; fusipa'u fe'avea'i e leai ni la'au mo vili matala, kalena, ma laina malulu; fa'alava ie mo le teuina o pa'u e le'i mae'a; fa'apitoa taulimaina o le silicone ma le fluororubber; ma fata ogaumu mo le mae'a ona fa'amalo. O faʻamanuiaga e aofia ai le faʻaumatiaina o le pipii, faʻaitiitia le faʻaogaina o mea faʻamalolo, puipuia le afifiina o le uila, ma faʻamautinoa le sologa lelei.

PTFE lipine mo paipa vailaʻau / vaʻa anti-corrosion, non-stick, ma le faʻamaufaʻailoga puipuiga e manaʻomia le faʻatusaina o meaʻai, faʻapipiʻi faʻapipiʻi, ma faʻasalalauga kemisi. Silicone PSA e fautuaina mo le 200-260 ° C ma acids / alkalis; PSA acrylic e tetee i solu faʻaletino ae faʻatapulaʻa le vevela ile ≤150°C. Mo le HF, faʻapunaina> 80% alkali, poʻo le chlorine trifluoride, faʻaaoga le PTFE-naʻo le ufiufi (leai se mea faʻapipiʻi faʻapipiʻi). Taua: fa'apipi'i o le so'otaga sili ona vaivai, ae le o le PTFE lava ia.

PTFE lipine umia mana ua faaleleia e ala i le ufiufi ma fofo optimization faagasologa. Ufiufi: vaega muamua (0.5-2μm silane primer e puipuia ai le pa'u o le pipii), mafiafia pipii 30-60μm (sili ona lelei mo le umiaina o le mana), fa'amama fa'amama, ma le 5-10μm filtration. Fa'amālōlōina: fa'avevela fa'asolosolo (80-100°C solvent removal → 120-140°C shaping → 150-220°C deep crosslinking), post-curing (40-60°C mo le 24-48h e malolo ai le atuatuvale), ma le maualalo o le mamafa o le felauaiga e puipuia ai le atuatuvale i totonu mai le fa'aitiitia o substrate. O le mea muamua e taua mo le maualalo o le malosi o le PTFE.

PTFE maualuga-vevela lipine e avea o se mea taua i le gaosiga semiconductor, ae le o se faʻaaogaina lautele. Fa'aoga autu: puipuiga o le wafer-level (plasma etching masking, CMP backside protection, CVD/PVD masking), faiga fa'apipi'i (fa'amauina fa'amau uaea, fa'amau so'o mo PCBs), ma le tausiga o meafaigaluega (anti-static roller wrapping, fa'ailoga potu mama). Manaoga mama mama: maualalo halogens (taofia le pala pad pad), siloxanes maualalo (<500 ppm, taofia insulating vaega vaega), ion u'amea maualalo (<1 ppm taitasi), ISO Vasega 4 potu mama slitting / afifiina, 10⁶-10⁹ Ω luga resistivity, ma le maualalo TVOC emissions.

Foma'i-grade PTFE maualuga-vevela lipine tu'ufa'atasia biocompatible PTFE substrate ma platinum-faamalolo silicone pipii. Vaega autu: ISO 10993 tausisia (leai se cytotoxicity, sensitization, poʻo le ita), faʻafefeteina faʻamaʻi faʻasolosolo (ausa/EO/gamma), 260°C teteʻe vevela. Lapataiga taua: aua le sili atu i le 260°C (asu oona i luga aʻe o le 300°C), o le gamma irradiation e mafai ona faʻaleagaina, faʻamaonia metotia faʻamaʻi, ma talosagaina faʻamaumauga atoatoa (ISO 10993 lipoti, MSDS, faʻamaumauga tuai). E le mo le fa'aogaina sa'o o le toto po'o le toto se'i vagana ua fa'amaonia faapitoa.

O le toe faʻaaogaina o le lipine PTFE e faʻalagolago i mea e fa: faʻapipiʻi faʻapipiʻi (maualuga crosslink density, feoaiga silikoni maualalo, fausaga microphase mo repositionable tack), taula substrate (faagaoioia luga + primer e puipuia ai le fesiitaiga atoa), ufiufi pito i tua (faʻasaʻo le laulau e puipuia ai le pipii i le taimi o le tatalaina), ma le taulimaina lelei (mama faʻapipiʻi luga, auala saʻo paʻu, aloese). O mea fa'apipi'i fa'aleleia e mafai ona fufulu vai e mafai ona toe fa'aleleia> 90% tack pe a uma ona fa'amamā.

Ole lipine PTFE lautele ole vevela e mana'omia ai se PSA siliki e fa'amautu le pipii mai -70°C i le 260°C. Fuafuaga autu autu: tulaga muamua-taula suiga (taofia delamination), moana-motu microstructure (MQ resin motu + polysiloxane vaega faifai pea), gradient crosslinking (maualuga-density totonu apa mo fetolofi, maualalo-density pito i fafo mo le maualalo o le vevela tack), ma le vevela-stabilized fillers (cerium oxide mo oxidation tetee). Phenyl-modified siloxane vaega e taofia ai le tioata maualalo-vevela, mafai ai ona fetuutuunai i lalo -100°C.
