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 elastic manatua ma silicone PSA fetolofi i lalo o le mamafa ma le vevela. Fofo: fa'alili fa'alili fa'ase'e - fufusi i luga o apa i fafo, matala i totonu - fa'aoga tapuni fa'alavelave fa'alavelave. 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 faʻaaogaina 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'ama'oti fa'alavalava fa'ama'i.

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 le PTFE maualuga-vevela lipine fa'aaogaina i fa'aoga fa'ase'ese'esega abrasive, e le lava la'au masani ma le fa'afefe vevela. Fa'atonuga o filifiliga autu: Taber abrasion gau (<15 mg/1000 cycles), fa'atumu suiga PTFE coating (carbon/graphite/MoS₂), PV fa'atapula'a fa'amaumauga, malosi substrate (≥200 N/cm), ma mating surface roughness (Ra 0.2-0.4 μm). O le puipuiga lelei o le pito ma le fusi atoa e taua tele mo le umi o le ola.

O le substrate PTFE e masani lava ona fa'asalaina masima masima (suavai vai <0.01%). Ae ui i lea, o le fa'atinoga atoa o lipine e fa'alagolago i le ituaiga pipi'i: PSA silicone e fa'afeagai ma si'osi'omaga o le gataifale (500-1000h su'ega masima,> 80% taofi pa'u); ua le manuia le PSA acrylic. Togafitiga lelei o luga, fa'aoga e leai ni pulumu, ma le fa'amaufa'ailoga pito i le fa'amaufa'ailoga silikoni e taua tele mo le fa'atuatuaina umi i luga o fa'afanua ma va'a i fafo.
