Nsalu zotentha kwambiri za PTFE zimakhala ndi magalasi apamwamba kwambiri a fiberglass ndi PTFE zokutira. Ntchito zazikuluzikulu zotumizira mafakitale (kuphika chakudya, kuyanika nsalu, zoyendera za PCB), chitetezo chowotcherera (zophimba zotchingira kutentha, zishango za spatter), kugwetsa ndi kupanga atolankhani otentha (kuumba mphira, PV lamination), kutchinjiriza magetsi (motor slot liners, zokutira zingwe), zomanga (madenga apabwalo, 30 + corrosion yazaka), mlengalenga (mabulangete otentha), ndi ntchito zapadera (kudula laser, kusindikiza kwa 3D).

Kuyera kwazinthu zopangira ndi maziko a PTFE ntchito ya nsalu yotentha kwambiri. Emulsion yoyera kwambiri ya PTFE (palibe ma ion zitsulo, palibe zotsalira zochepetsera ma molekyulu) zimatsimikizira kukana kutentha (palibe chikasu mpaka 260 ° C), osasunthika osasunthika, komanso mphamvu yayikulu ya dielectric. Kwa magalasi a fiberglass, E-glass yopanda alkali (Na₂O <0.8%) imasunga mphamvu ndi kutsekemera pa kutentha kwakukulu; magalasi apakati/apamwamba-alkali amachititsa kuwonongeka. Kuchotsa kwathunthu kwa zoluka zoluka kumalepheretsa carbonization ndi delamination. Kuyera kumakhudza mwachindunji moyo wautumiki, kutsata chakudya, komanso kudalirika kwamagetsi.

Moyo wa ntchito ya nsalu ya PTFE yotentha kwambiri umasiyana kwambiri ndi kagwiritsidwe ntchito. Mankhwala odana ndi dzimbiri amatha kukhala zaka 3+ (4x motalika kuposa mphira). Ma tray ophikira chakudya miyezi yapitayi ndi kuwonongeka pang'ono. Malamba otengera mafakitale amavala kuchokera ku kukangana. PV lamination (150 ° C, EVA contact) ali ndi moyo wapakati. Ntchito zolimbana kwambiri (ma abrasive disc) amakhala ndi moyo waufupi. Mfundo zazikuluzikulu: kuwongolera kutentha (kukhala ≤260 ° C), pewani mikwingwirima yakuthwa, kuyeretsa nthawi zonse, ndikusintha munthawi yake mukakhala matuza kapena achikasu.

Nsalu ya PTFE yotentha kwambiri (PTFE-yokutidwa ndi fiberglass) imakhala yayitali kwambiri ikasungidwa pansi pa 260 ° C, kutali ndi zopinga zakuthwa, ndikutsukidwa ndi zida zofewa. Zinthu zazikulu zomwe zimalepheretsa moyo: kuwonongeka kwamafuta opitilira 260 ° C, kugwedezeka kwa kutentha chifukwa cha kutentha / kuzizira kofulumira, kutopa kwamakina chifukwa chopindika ndi kukangana, kuukira kwamankhwala kuchokera kuzitsulo zosungunula za alkali kapena zotsekemera zolimba, kuwonongeka kwa zitsulo pakutsuka, komanso kuwonekera kwa UV kuti mugwiritse ntchito panja. Ubwino wa zokutira ndi gawo lapansi ndizofunikanso.

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.

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.

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 yosasintha 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.

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.
