Nsalu ya PTFE yotentha kwambiri (PTFE-yokutidwa ndi fiberglass) ndi yabwino kutenthetsa ma microwave chifukwa imatumiza ma microwave popanda kuyamwa mphamvu, imalimbana ndi 260 ° C, ndipo imakhala ndi malo osasunthika. Mapulogalamuwa akuphatikiza ma microwave ophikira, malamba owumitsira makina owumitsira makina, zomangira zopangira mafuta kuti zigayidwe, ndi matumba a popcorn a microwave. Magulu a FDA omwe amapezeka kuti agwirizane ndi chakudya.

Nsalu ya PTFE yotentha kwambiri (PTFE-yokutidwa ndi fiberglass) imakhala yosasunthika bwino chifukwa gawo lapansi la fiberglass ndilokhazikika. Nsalu zoonda (0.08mm) zimapulumuka mazana mpaka masauzande; magiredi olemera (> 0.25mm) amasweka pambuyo pambiri. Zoluka za Satin zimaposa zoluka zamba. Kuti mupirire mobwerezabwereza, ganizirani filimu yolimba ya PTFE kapena nsalu yochokera ku aramid m'malo mwake.

Tepi ya PTFE yotentha kwambiri imathandizira makampani a PV m'maudindo awiri osiyana: njira zogwiritsira ntchito (zimaletsa kumatira kwa EVA kusefukira pa laminator, chigoba cha solder) ndi kusungunula kwa moyo wautali (kukulunga kwa mabasi, kukonza bokosi lolumikizana). Kuti mugwiritse ntchito kosatha mkati, matepi ayenera kudutsa IEC 61215: 1000-2000h kutentha kwachinyezi, UV, njinga yamoto yotentha (-40 ° C mpaka + 85 ° C), ndi silikoni PSA ndi shrinkage <1%.

Nsalu zotentha kwambiri za PTFE (PTFE-zokutidwa ndi fiberglass) zimagwiritsidwa ntchito kwambiri posindikiza nsalu ndi utoto wa malamba osindikizira kutentha (180-230°C), zovundikira patebulo losindikizira, zowumitsa malamba, malamba ophatikiza makina, ndi zokutira zogudubuza. Malo ake osamata amalepheretsa zotsalira za inki / zomatira, kuchepetsa nthawi yoyeretsa komanso kukonza bwino nsalu. Malamba opanda malire amathandizira kupanga mosalekeza.

Tepi ya PTFE yotentha kwambiri yomwe imagwiritsidwa ntchito pamipeni yosindikiza kutentha ndi zomangira zosindikizira zimapereka mfundo zinayi zazikuluzikulu: zimateteza kumamatira kwa pulasitiki yosungunuka (kuchotsa nthawi yopuma), kumateteza kusindikiza kokwera mtengo, kumapangitsa kutentha / kupanikizika kwa zisindikizo zosasinthasintha, ndi kuchepetsa kukangana kwa filimu. Fiberglass-backed tepi (0.13-0.25 mm) yokhala ndi silicone PSA (≥260 ° C) ikulimbikitsidwa. Anti-static wakuda tepi ya mizere yothamanga kwambiri.

PTFE high-temperature nsalu (PTFE- TACHIMATA fiberglass fiberglass) ndi umafunika fyuluta TV zinthu kwambiri: flue gasi kuchotsa fumbi (simenti, zinyalala incineration, malasha boilers mpaka 260 ° C), dzimbiri sefa madzi (zidulo, alkali, mafuta), chakudya/mankhwala wosabala kusefera, ndi HEPA zosefera zipinda. Pansi yopanda ndodo imalepheretsa fumbi kuti ifike ndipo imalola kuyeretsa kosavuta. Mamembrane-laminated class amapeza zotulutsa zotsika kwambiri.

Nsalu ya PTFE yotentha kwambiri imakhala yabwino kwambiri yotchinjiriza magetsi kuchokera ku -180°C mpaka 260°C: mphamvu ya mphamvu > 10¹³ Ω·cm pa 200°C, dielectric yokhazikika pa 2.0-2.1. Pamwamba pa 260 ° C, PTFE imafewetsa, imawola pamwamba pa 327 ° C, kutaya kutsekemera kosatha. Pansi pa 0 ° C, kutchinjiriza kumayenda bwino koma zokutira zimakhala zolimba. Khalani mkati mwa 260 ° C kuti mugwire ntchito yodalirika.

The madzi nthunzi chotchinga katundu wa PTFE zomatira tepi anatsimikiza makamaka ndi ❖ kuyanika zolakwika (micropores, microcracks, CHIKWANGWANI wicking) osati PTFE a intrinsic hydrophobicity. Filimu yoyera ya PTFE imapereka WVTR yapakatikati yokha. Mipikisano wosanjikiza zokutira ndi lamellar fillers (mica, magalasi flakes) amapanga labyrinth zotsatira, kuchepetsa kwambiri kufala kwa nthunzi. Kuti musindikize chinyezi chambiri, tchulani zokutira zolimba.

Nsalu yotentha kwambiri ya PTFE (PTFE- TACHIMATA fiberglass) ndi yabwino kwa malamba otumizira chakudya chifukwa cha 260°C kukana kutentha, -70°C kusinthasintha kuzizira, pamwamba osagwira ndodo, ndi kutsata kwa FDA. Ntchito zazikuluzikulu: mauvuni ophika buledi (mabisiketi, buledi, pitsa), zotengera zakudya zokazinga, mizere yozizirira maswiti, machubu oziziritsa, zosindikizira kutentha, ndi zokutira zogudubuza. Amachepetsa kutaya ndi kuyeretsa nthawi.

Kukana kwa PTFE kutentha kwapamwamba kwambiri kwa tepi yomatira pansi pa katundu wanthawi yayitali (makamaka pa 200-260 ° C) kumatsimikiziridwa ndi zinthu ziwiri: silicone PSA crosslink density (high crosslinking imalepheretsa kutuluka) ndi mtundu wa gawo lapansi (fiberglass-reinforced PTFE imatsutsa kuzizira kozizira; filimu yoyera ya PTFE imakwawa). Zomatira zosagwirizana zimalephera mwachangu pakutentha kwakukulu. Zomata zokhuthala zimawonjezera chiopsezo chokwera.
