Indwangu ye-PTFE yokushisa ephezulu (i-PTFE-coated fiberglass) ilungele ukushisisa i-microwave ngoba ihambisa ama-microwave ngaphandle kokumunca amandla, imelana no-260°C, futhi inendawo engabambeki. Izicelo zihlanganisa omata bokubhaka be-microwave, amabhande omshini wokomisa wemboni, ama-reactor linings okugaya kwamakhemikhali, kanye nama-microwave popcorn bag liners. Amamaki e-FDA atholakalayo ukuze axhumane nokudla.

Indwangu ye-PTFE ephezulu yokushisa (i-PTFE-coated fiberglass) inokumelana nokugoba okumpofu ngenxa yokuthi i-fiberglass substrate i-brittle ngokwemvelo. Izindwangu ezizacile (0.08mm) zisinda emakhulwini kuya ezinkulungwaneni zokugoqa; amamaki asindayo (>0.25mm) aqhekeka ngemva kwenqwaba. I-Satin weave idlula i-plain weave. Ukuze uthole ukugoba okuqhubekayo, cabangela ifilimu ye-PTFE eqinile noma indwangu esekwe ku-aramid esikhundleni.

Itheyiphu ye-PTFE yokushisa okuphezulu isebenzela imboni ye-PV ngezindima ezimbili ezihlukene: inqubo esebenzisekayo (ivimbela ukunamathela okuchichima kwe-EVA kuma-laminator, imaski ye-solder) kanye nokufakwa kwempilo ende (ukugoqa kwebhasi, ukulungiswa kwebhokisi lokuhlangana). Ngokusetshenziswa kwangaphakathi unomphela, amateyipu kufanele adlule ku-IEC 61215: ukushisa okumanzi okungu-1000-2000h, i-UV, ukuhamba ngebhayisikili okushisayo (-40°C kuya ku-+85°C), ne-silicone PSA kanye nokuncipha kuka-<1%.

Indwangu ye-PTFE yokushisa ephezulu (i-PTFE-coated fiberglass) isetshenziswa kakhulu ekuphrinteni kwendwangu nokudaya amabhande okuphrinta okudlulisa ukushisa (180-230°C), izembozo zetafula lokuphrinta isikrini, amabhande anezikhala okomisa, amabhande omshini wokuhlanganisa, nokugoqa kwamarola. Indawo yayo enganamathi ivimbela izinsalela zikayinki/zokunamathela, kunciphisa isikhathi sokuhlanza nokuthuthukisa ikhwalithi yendwangu. Amabhande angapheli angenamthungo anika amandla ukukhiqiza okuqhubekayo.

Itheyiphu ye-PTFE yokushisa okuphezulu esetshenziswa emimeseni evala ukushisa nemicu yokuvala iletha amanani amane abalulekile: ivimbela ukunamathela kwepulasitiki okuncibilikisiwe (iqeda isikhathi sokuphumula), ivikela ukufa kokuvalwa okumba eqolo, yenza kube lula ukushisa/ingcindezi yezivalo ezingaguquki, futhi inciphisa ukungqubuzana kwefilimu. Kunconywa itheyiphu ye-Fiberglass-backed (0.13-0.25 mm) ene-silicone PSA (≥260°C). I-Anti-static black tape yemigqa enesivinini esikhulu.

Indwangu ye-PTFE enezinga eliphezulu lokushisa (i-PTFE-coated fiberglass) iyisihlungi semidiya ye-premium yezimo ezimbi kakhulu: ukukhishwa kwegesi ye-flue (usimende, ukushiswa kwemfucuza, amabhayela amalahle afika ku-260°C), ukuhlunga uketshezi okugqwalayo (ama-acids, ama-alkali, uwoyela), ukuhlunga ukudla/kwemithi okuyinyumba, nezihlungi zegumbi lokuhlanza i-HEPA. Indawo enganamatheli ivimba uthuli futhi ivumela ukuhlanzwa kalula. Amabanga ane-Membrane-laminated athola ukukhishwa okuphansi kakhulu.

Indwangu ye-PTFE enezinga eliphezulu lokushisa igcina kahle kakhulu ukwahlukanisa kukagesi ukusuka ku- -180°C kuya ku-260°C: ukumelana nevolumu >10¹³ Ω·cm ku-200°C, i-dielectric ihlala iqinile kokuthi 2.0-2.1. Ngaphezulu kuka-260°C, i-PTFE iyathamba, ibole ngaphezu kuka-327°C, ilahlekelwa ukufakwa kwamagciwane unomphela. Ngaphansi kuka-0°C, ukwahlukanisa kuyathuthuka kodwa ukunamathela kuba nzima. Hlala ku-260°C ukuze uthole ukusebenza okuthembekile.

Isici sokuvimbela umhwamuko wamanzi wetheyiphu yokunamathisela ye-PTFE sinqunywa ngokuyinhloko ngokulimala kokumboza (ama-micropores, ama-microcracks, ama-fiber wicking) kune-PTFE's intrinsic hydrophobicity. Ifilimu ye-PTFE ehlanzekile inikeza i-WVTR emaphakathi kuphela. I-Multi-layer coating kanye ne-lamellar fillers (i-mica, ama-glass flakes) yenza umphumela we-labyrinth, unciphisa kakhulu ukuhanjiswa komphunga. Ukuze uvale uphawu lomswakama ophezulu, cacisa ama-coatings aminyene.

Indwangu ye-PTFE enezinga eliphezulu lokushisa (i-PTFE-coated fiberglass) ilungele amabhande okuthutha ukudla ngenxa yokumelana nokushisa kwayo okungu-260°C, -70°C ukuguquguquka okubandayo, indawo enganamatheli, kanye nokuthobela kwe-FDA. Izicelo ezibalulekile: ohhavini bebhikawozi (amabhisikidi, isinkwa, i-pizza), izinto zokuthutha ukudla okuthosiwe, izintambo zokupholisa uswidi, imihubhe eqandayo, izinto zokuvala ukushisa, nokugoqwa kwamarola. Yehlisa imfucuza kanye nesikhathi sokuhlanza.

Ukumelana ne-Creep ye-PTFE high-temperature adhesive tape ngaphansi komthwalo ongaguquki wesikhathi eside (ikakhulukazi ku-200-260 ° C) kunqunywa izici ezimbili: i-silicone PSA crosslink density (i-crosslinking ephakeme ivimbela ukugeleza) kanye nohlobo lwe-substrate (i-fiberglass-reinforced PTFE imelana nokukhasa okubandayo; ifilimu ye-PTFE ehlanzekile iyakhasa). Ingcina engaxhunywanga ihluleka ngokushesha ekushiseni okuphezulu. Izendlalelo zokunamathela eziqinile zandisa ingozi yokukhuphuka.
