PTFE lipine mo paipa vailaʻau / vaʻa anti-corrosion, non-stick, ma le faʻamaufaʻailoga puipuiga e manaʻomia ai le faʻatusaina o mea'ai, faʻapipiʻi faʻapipiʻi, ma vailaʻau vailaʻau. 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 taofiofia o le mana), fa'amama fa'amama, ma 5-10μm filtration. Fa'amālōlōina: fa'avevela fa'asolosolo (80-100°C solvent removal → 120-140°C shape → 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 substrate shrinkage. 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 fa'amau mo PCB), ma le tausiga o meafaigaluega (anti-static roller wrapping, fa'ailoga potu mama). Manaoga 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), faʻafefete 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 o substrate (faagaoioia luga + primer e puipuia ai le fesiitaiga atoatoa), ufiufi pito i tua (faʻasaʻo vaega e puipuia ai le pipii i le taimi o le tatalaina), ma le faʻaogaina lelei (mama faʻapipiʻi luga, saʻo auala paʻu, aloese). O mea fa'apipi'i e mafai ona fufulu vai e mafai ona toe fa'aleleia> 90% fa'amau pe'a uma ona fa'amama.

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.

Aokai PTFE debuted lona laina oloa atoa i APFE Shanghai 2026 (Booth 6T602, Hall 6). O oloa faʻaalia e aofia ai lipine PTFE faʻamalosia fiberglass, ata PTFE mama, faʻailoga anti-static, ma fusi faʻafefe maualuga - e ufiufi ai meaʻai, lamination PV, maa lithium, mea faʻaeletoroni, ma afifiina. O le faʻaaliga e oʻo atu ia Iuni 26. O oloa uma e lagolagoina faʻamatalaga masani.

I le taimi o le faʻapipiʻiina o le lipine PTFE, o le faʻaogaina o le solvent volatilization rate o le faʻapipiʻi maʻaleʻale silikoni o se mea taua tele. Vave tele → pa'u i luga o le fogaeleele, le lelei le fa'asa'osa'o, 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'amago 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 leiloa pipii pe a uma ona faaaoga soo ona o le eleelea (pefu, suauu silicone), pipii le atoatoa le lelei (toega), po o le vaivai substrate sootaga. Fofo: maualuga-crosslink silicone PSA (maualalo femalagaiga, paleni tack/uʻu malosi), muamua togafitiga i luga o le PTFE substrate, mafiafia fiberglass lagolago, ma le tagofiaina lelei (mea mama, paʻu malulu, 180 ° tulimanu). Ole su'ega fa'atele e fa'amaonia le fa'aleleia.

PTFE maualuga-vevela lipine teuina i lalo o tulaga maoti (10-25°C, 40-70% RH, ese mai le UV / mamafa mamafa) ei ai se fata ola masani o le 3-6 masina (faailoga maualuga e oo atu i le 12 masina). Tulaga fa'aleagaina: e le tatau ona pa'ū le malosi o le pa'u i lalo ole 70% ole tau muamua; leai se mea fa'apipi'i toega pe a uma ona aveese le vevela; leai se carbonization po'o ta'e i le vevela fua. Su'esu'ega vave: lagona fa'amavae tusi, su'ega toega 260°C, ma su'ega fa'aitiitia lamination.
