PTFE high-temperature tepi ine yakanakisa munyu kupfapfaidza kuramba, asi iyo isina simba mapoinzi ndiyo inonamira layer uye fiberglass substrate mipendero. Nzira dzekuongorora: 1000h neutral salt spray (NSS) bvunzo, kuyera peel simba retention (≥80% inodiwa), urema hwekuona (kusimudza, blistering), uye simbi substrate corrosion. Kunzvimbo dzemugungwa uye dzakakwirira-munyu-mhute: shandisa silicone PSA (kwete acrylic), yakanyudzwa zvizere PTFE substrate, chisimbiso mipendero nemamiriro ekunze-resistant sealant, uye shandisa primer panzvimbo dzesimbi.

Silicone pressure-sensitive adhesives (PSA) yePTFE high-temperature matepi anosiyana zvakanyanya mukuchembera kwakanyanya. Methylphenyl silicone PSA inochengetedza > 85% peel simba mushure me250 ° C / 7 mazuva, nepo standard methyl mhando inodonha kusvika 50-70%. Kuwedzera-kuporeswa (hydrosilylation) masisitimu anopa kugadzikana kuri nani pane peroksidi-yakarapwa. Nekuenderera mberi kwe200°C+ sevhisi, sarudza magiredhi ekuwedzera-akarapwa epamusoro-phenyl.

Thermally conductive PTFE pressure-sensitive adhesive (PSA) matepi anofanira kuitisa kupisa achiramba akanamatira. Kuwedzera mafirita kunonatsiridza kupisa conductivity asi kunokanganisa kunamatira. Optimal balance inoshandisa spherical coarse particles (se conductive skeleton) yakasanganiswa neakanaka zvimedu (kuzadza voids), ichichengeta yakazara mafirita kurodha pamusoro pechikumbaridzo chepercolation. Dzivisa flakes uye fibers; vanouraya simbi.

PTFE high-temperature tepi inoshandira PV indasitiri mumabasa maviri akasiyana: process consumable (inodzivirira EVA kufashukira adhesion pane laminators, solder mask) uye refu-hupenyu insulation (kuputira bhasi, junction bhokisi fixation). Nechigarire kushandiswa kwemukati, matepi anofanira kupfuura IEC 61215: 1000-2000h yakanyorova kupisa, UV, thermal cycling (-40 ° C kusvika + 85 ° C), ine silicone PSA uye shrinkage <1%.

PTFE high-temperature tepi inoiswa kune kupisa-sealing mapanga uye sealing strips inopa mana anokosha adhesion: inodzivirira yakanyungudutswa yepurasitiki adhesion (inobvisa downtime), inodzivirira inodhura yekuisa chisimbiso inofa, homogenizes kupisa / kudzvanywa kwezvisimbiso zvinowirirana, uye inoderedza kukwesha kwefirimu. Fiberglass-backed tape (0.13-0.25 mm) ine silicone PSA (≥260 ° C) inokurudzirwa. Anti-static nhema tepi yemitsetse inomhanya-mhanya.

The water vapour barrier property yePTFE adhesive tepi inotariswa zvakanyanya nekukoira (micropores, microcracks, fiber wicking) pane PTFE's intrinsic hydrophobicity. Yakachena PTFE firimu inopa chete yepakati WVTR. Multi-layer coating uye lamellar fillers (mica, girazi flakes) inogadzira labyrinth mhedzisiro, inoderedza zvakanyanya kutapurirana kwemhute. Kuti uvhare hunyoro hwepamusoro, tsanangura densified coatings.

Kune PTFE yepamusoro-tembiricha matepi pasi pekunyudzwa kwenguva refu, iyo PTFE substrate inoramba iine chemikemikari inert, asi iyo yekunamatira layer ndiyo isina simba. Mvura inopedza silicone PSA; mvura yemunyu inokurumidza kuita ngura. Kune makemikari ane hukasha, fluorosilicone kana perfluoropolyether adhesives - kana adhesive-isina PTFE tepi - inodiwa. Peel simba kurasikirwa kusvika ku40% mushure memaawa makumi mana nemasere mumvura.

PTFE yakakwirira-tembiricha tepi inoda kuchengetedza kwakaringana kuchengetedza kunamatira kwayo, kuchinjika, uye kuburitsa kuita. Zvinodiwa zvakakosha zvinosanganisira kudzora tembiricha (10-30 ° C), humidity iri pasi pe60%, kudzivirira mwenje, kuparadzaniswa kwemakemikari, kuiswa kwakamira, uye kufefetedza. Tevera FIFO inventory management uye ongorora nguva dzose.

Sarudzo yepepa rekuburitsa kana firimu substrate uye mumiriri wekuburitsa zvinokanganisa kugadzikana kwekuchengetedza uye peeling kuita kwePTFE yakakwirira-tembiricha tepi. Ichi chinyorwa chinofananidza PET vs. kraft paper substrates uye silicone vs. fluorinated release agents, inokurudzira kusanganiswa kwakakwana kwezero-residue peeling uye kuvimbika kwenguva refu.
