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 fusia. 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 tulaga fata ola o le 3-6 masina (togi 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.

O lo'o fa'apipi'iina le lipine PTFE e mafai ona atia'e le pipi'i fa'atasi (poloka) ma le fa'apipi'i fa'apipi'i i le taimi e teu ai mo se taimi umi. Mafuaaga: PTFE ata tifaga manatua elastic ma silicone PSA fetolofi i lalo o le mamafa/vevela. Puipuia: fa'alili fa'alili fa'alili (fa'amuta i fafo, tatala totonu) i le taimi o le gaosiga, fa'atasi ai ma le fa'apipi'i fa'apipi'i i le itu e le pipi'i. Teu i le -15°C i le 40°C, 30-70% RH, faalava i luga o fata, sui ta'i kuata. Mo fa'ailoga mafiafia fa'apipi'i, fa'aopoopo le pepa fa'amatu'u i le va o apa.

PTFE maualuga-vevela lipine teuina i lola fomu e mafai ona mafatia mai le pipii interlayer (polokaina) ma fesiitai fesiitai i le itu e le o laau. O a'a mafua'aga: PTFE ata tifaga manatua elastic ma silicone PSA fetolofi i lalo o le mamafa ma le vevela. Fofo: fa'ase'e fa'a'ami'i fa'alili – fufusi i luga o apa i fafo, matala i totonu o apa - fa'aoga tapuni tapuni tete'e. Fa'ato'a fa'apipi'i fa'amuta, teuina lelei (15-40°C, 30-70% RH), tu'u fa'ata'atia, ma ta'i kuata ta'i ta'i.

PTFE maualuga-vevela lipine faʻaaogaina i meaʻai faʻafesoʻotaʻi e tatau ona faʻaaloalo i tapulaʻa o le vevela: ≤260 ° C mo le faʻaaogaina faifaipea (leai se taimi faatapulaaina), 260-300 ° C mo na o le 30 minute, ma le> 300 ° C faʻasaina. O le lipine e mo na'o le fa'afeso'ota'i fa'atasi (lafu fata, fa'amau fa'amau fa'avevela), ae le o le afifiina sa'o o mea'ai. 'Aua ne'i fa'agaioi e aunoa ma se utaina o mea'ai (fa'amago fa'amafanafana). Sui pe afai ua ma'i, samasama, pe masaesae.

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 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.
