PTFE high-temperature fabric (PTFE-coated fiberglass) yakanakira microwave kudziyisa nekuti inoendesa microwaves isingatore simba, inopikisa 260°C, uye ine nzvimbo isina tsvimbo. Zvishandiso zvinosanganisira ma microwave ekubikira, mabhandi ekuomesera emuindasitiri, mareactor linings ekugayiwa kwemakemikari, uye microwave popcorn bag liner. FDA mamakisi anowanikwa kune chikafu kuonana.

PTFE high-temperature jira (PTFE-yakavharidzirwa fiberglass) haina kusimba kuchinjika nekuti iyo fiberglass substrate inogadzika brittle. Machira matete (0.08mm) anopona mazana kusvika kuzviuru zvemapete; magiredhi anorema (> 0.25mm) anotsemuka mushure memakumi mazhinji. Satin weave inodarika plain weave. Kuti urambe uchipeta, funga yakasimba PTFE firimu kana aramid-based fabric panzvimbo.

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

PTFE high-temperature fabric (PTFE-coated fiberglass) inoshandiswa zvakanyanya mumucheka kudhinda uye kudhayira kupisa kupisa mabhandi ekudhinda (180-230 ° C), zvivharo zvetafura yekudhinda, kuomesa mesh mabhandi, fusing machine mabhandi, uye roller wrapping. Nzvimbo yayo isina tsvimbo inodzivirira inki / inonamatira zvakasara, kuderedza kuchenesa nguva yekuchenesa nekuvandudza kunaka kwejira. Mabhandi asingagumi asingagumi anogonesa kuenderera mberi kwekugadzirwa.

PTFE high-temperature tepi inoiswa kune kupisa-sealing mapanga uye sealing strips inopa mana akakosha 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.

PTFE high-temperature fabric (PTFE-coated fiberglass) is a premium filter media for extreme conditions: flue gas dust kubvisa (simende, kupisa tsvina, marasha boilers anosvika 260°C), corrosive liquid filtration (acids, alkalis, oils), food/pharmaceutical sterile filtration, uye HEPA cleanroom filters. Isiri-tsvimbo inodzivirira guruva caking uye inobvumira kuchenesa nyore. Membrane-laminated mamakisi anowana ultra-low emissions.

PTFE high-temperature jira rinochengetedza zvakanaka magetsi ekudzivirira kubva -180°C kusvika 260°C: volume resistivity >10¹³ Ω·cm pa200°C, dielectric inogara yakagadzikana pa2.0-2.1. Pamusoro pe260 ° C, PTFE inopfava, inoora pamusoro pe327 ° C, ichirasikirwa nekudzivirira zvachose. Pazasi pe 0°C, kuvharisa kunonatsiridza asi kupfeka kunoita brittle. Gara mukati me260 ° C kuitira kushanda kwakavimbika.

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.

PTFE high-temperature fabric (PTFE-coated fiberglass) yakanakira mabhandi ekutakura chikafu nekuda kwe260°C kupisa kwayo, -70°C kutonhora kuchinjika, kusinga tsvinda, uye kutevedzera FDA. Zvishandiso zvakakosha: mahovhoni ekubheka (mabhisikiti, chingwa, pitsa), kutakura chikafu chakakangwa, mitsara yekutonhodza siwiti, tunnel dzinoomesa nechando, zvivhariso zvekupisa, uye kuputira. Inoderedza tsvina uye nguva yekuchenesa.

Creep resistance yePTFE high-temperature adhesive tape pasi pemutoro wenguva refu (kunyanya pa 200-260 ° C) inotarirwa nezvinhu zviviri: silicone PSA crosslink density (yakakwirira crosslinking inodzivirira kuyerera) uye substrate type (fiberglass-yakasimbiswa PTFE inopesana nechando chinokambaira; pure PTFE film creeps). Uncrosslinked adhesive inokundikana nekukurumidza pakupisa kukuru. Makobvu anonamira akaturikidzana anowedzera njodzi inokambaira.
