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.

O le fausaga o foliga tipi o le PTFE maualuga-vevela lipine e afaina tonu ai le pipii oozing ma le siiina o pito i le taimi o le talosaga. O le le lelei o le slitting (lau mata'itusi, le sa'o le tulimanu) e fai ai filo kelu, manifinifi le pito o le fa'apipi'i, ma fa'aalia ai pupunifi tioata - e o'o atu i le tafe, vaivai le fusi, ma le si'i i lalo o le vevela po'o le vevesi. O foliga fa'a'au'au fa'aletonu (gauvale, fa'aoso) e mafua ai le le tutusa o le tufatufaina o le mamafa, fa'aosoina le fetolofi i le taimi e teu ai. O foliga pito sili ona lelei e lamolemole, fuga, ma e leai se mea e faaleagaina - e fai ma fa'amaufa'ailoga e loka ai le mea fa'apipi'i ma fa'amautinoa le pipi'i atoa.

I le taimi o le faʻapipiʻiina o le lipine PTFE, o le faʻaogaina o le solvent volatilization rate o le faʻapipiʻi faʻamaʻi-maʻaleʻale silikoni o se mea taua tele. Vave tele → pa'u i luga o le eleele, le lelei le fa'asa'osa'oina, pu (solvent ua maileia), ma lua (fa'a'ele'ele po'o le fa'aleaga mea). Telegese → pa'u'u, mafiafia pito, ma fa'afu i luga ole la'ititi-malosi PTFE. Le ta'iala lelei: fa'agesegese le fa'amamago muamua mo le fa'ata'atiaga ma le sola ese, ona fa'avaveina lea o le fa'agogo mo le fa'avasegaina. Fa'aaogā mea fa'afefiloi fa'afefiloi (toluene/xylene + fa'amago vave) ma le vevela o le ogaumu (maualalo → feololo → maualuga).

PTFE maualuga-vevela lipine e sili ona lelei tete'e masima masima, ae o vaega vaivai o le apa pipii ma pito substrate fiberglass. Metotia Su'esu'ega: 1000h su'ega masima fa'aitu'u (NSS), fuaina le malosi o le pa'u (≥80% mana'omia), fa'aletonu va'aia (siitia, fa'afefeteina), ma le pala o mea uamea. Mo si'osi'omaga o le gataifale ma le puao-masima: fa'aaoga le PSA silikoni (e le'o le acrylic), fa'apalapala PTFE atoa, fa'amau fa'amau i le fa'amaufa'ailoga tau-tau, ma fa'aulu i luga o u'amea.
