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.

Silicone pressure-sensitive adhesives (PSA) mo lipine vevela maualuga o le PTFE e eseese lautele i le maualuga o le vevela faʻatinoga o le matua. Methylphenyl silicone PSA tumau> 85% pa'u malosi pe a uma le 250 ° C / 7 aso, ae o le tulaga masani methyl ituaiga pa'ū i le 50-70%. Fa'aopoopo-fa'amalologa (hydrosilylation) faiga e ofoina atu sili atu le mautu nai lo peroxide-fa'amalolo. Mo le fa'aauauina o le 200°C+ auaunaga, filifili fa'aopoopo-fa'amalologa maualuga-phenyl togi.

O lipine fa'apipi'i ma'ale'ale a le PTFE (PSA) e tatau ona fa'avevela a'o pipi'i. O le fa'aopoopoina o mea fa'atumu e fa'aleleia ai le fa'avevelaina o le vevela ae afaina ai le pipii. O le paleni sili ona lelei e fa'aogaina ai vaega ma'ale'ale lapotopoto (e pei o se auivi fa'aoso) fa'afefiloi ma ni vaega laiti (e fa'atumu ai avanoa), fa'amautu le uta fa'atumu atoa i luga a'e lava o le fa'alava. Aloese mai fasipepa ma alava; latou te fasi tui.

PTFE maualuga-vevela lipine tautua le alamanuia PV i ni matafaioi maoti se lua: faagasologa consumable (taofia EVA adhesion i luga o laminators, solder ufimata) ma insulation umi-ola (busbar afifi, junction pusa fixation). Mo le fa'aoga tumau i totonu, e tatau ona pasi lipine IEC 61215: 1000-2000h vevela vevela, UV, uila uila (-40 ° C i le + 85 ° C), fa'atasi ai ma le PSA silicone ma fa'aitiitia <1%.

PTFE maualuga-vevela lipine faʻaogaina i naifi faʻamaufaʻailoga vevela ma faʻamaufaʻailoga faʻamaufaʻailoga e tuʻuina atu ai faʻamaufaʻailoga autu e fa: puipuia le pipii palasitika liusuavai (aveesea taimi faʻaletonu), puipuia mate faʻamaufaʻailoga taugata, homogenizes vevela / mamafa mo faʻamaufaʻailoga faifaipea, ma faʻaitiitia feteʻenaʻiga ata. O lo'o fa'atonuina le mea fa'apipi'i fa'apipi'i-fiberglass (0.13-0.25 mm) fa'atasi ai ma le PSA silicone (≥260°C). Anti-static lipine uliul. Anti-static lipine uliuli mo laina televave.

O le vai ausa pa pupuni meatotino o le PTFE faapipii lipine e fuafuaina muamua e le faʻaleagaina o le ufiufi (micropores, microcracks, fiber wicking) nai lo le PTFE's intrinsic hydrophobicity. O ata tifaga PTFE mama e ofoina atu na'o le WVTR. E fa'apipi'i fa'alava ma fa'atumu fa'atumu (mica, fa'amea tioata) e fa'atupu ai se labyrinth, fa'aitiitia ai le felauaiga ausa. Mo fa'amaufa'ailoga maualuga-sūsū, fa'amaoti fa'alavalava fa'ato'a.

Fetolofi teteʻe o le PTFE maualuga-vevela mea faapipii lipine i lalo o taimi umi uta tumau (aemaise lava i le 200-260°C) e fuafuaina e ni mea se lua: silicone PSA crosslink density (crosslinking maualuga e taofia tafe) ma substrate ituaiga (fiberglass-faamalosia PTFE tetee malulu fetolofi; mama ata tifaga PTFE fetolofi). O mea fa'apipi'i e le'i feso'ota'i e vave ona pa'u i le vevela tele. O fa'amau fa'apipi'i mafiafia e fa'ateleina ai le fa'alavelave fetolofi.

Mo PTFE lipine vevela maualuga i lalo o le faatofu umi, o le PTFE substrate tumau chemically inert, ae o le apa pipii o le vaega vaivai. O le vai e faʻavaivaia PSA silicone; vai masima e faatelevave ai le pala. Mo vailaʻau faʻamalosi, faʻapipiʻi fluorosilicone poʻo perfluoropolyether - poʻo le lipine PTFE e leai se pipii - e manaʻomia. Ole malosi ole pa'u ile 40% ile mae'a ole 48 itula ile vai.

PTFE maualuga-vevela lipine e manaʻomia le teuina lelei e faʻamautu ai lona pipii, fetuutuunai, ma faʻamalolo faʻatinoga. Mana'oga autu e aofia ai le pulea o le vevela (10-30°C), susu i lalo ole 60%, aloese mai le malamalama, fa'a'ese'ese vaila'au, tu'u sa'o, ma le ea. Mulimuli i le pulega ole lisi ole FIFO ma asiasi soo.

O le vevela suiga tioata (Tg) o le faʻapipiʻi faʻapipiʻi silikoni e tusa ma le -120°C - e sili atu le maualalo nai lo mea faʻapipiʻi acrylic. O lenei Tg ultra-maualalo e taofia le PTFE maualuga-vevela lipine fetuutuunai ma pipii e oo lava i le -70°C, puipuia mavaevae ma mafai ona pipii mau faatuatuaina i talosaga cryogenic.
