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

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 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 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 belt, 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 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.

PTFE high-temperature fabric (PTFE-coated fiberglass) is a premium filter media for a extreme conditions: flue gas dust kubvisa (simende, tsvina yekupisa, marasha boilers kusvika 260 ° C), corrosive liquid filtration (acids, alkalis, oils), chikafu/mishonga inosvibisa 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 yakanakisa 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 kwekupisa kwayo 260°C, -70°C kutonhora kuchinjika, kusinga tsvinda, uye kutevedzera FDA. Mashandisirwo akakosha: maovheni ekubheka (mabhisikiti, chingwa, pitsa), kutakura chikafu chakakangwa, mitsara yekutonhodza maswiti, 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.
