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.

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 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 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'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 atili 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'aulu) fa'afefiloi ma ni vaega laiti (e fa'atumu ai gaogao), fa'atumauina le utaina atoa o mea fa'atumu 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'ama'oti fa'alavalava fa'ama'i.
