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 imakhala yokhazikika mpaka 300 ° C, koma pamoto imawola ndikutulutsa mpweya wapoizoni kwambiri: hydrogen fluoride (HF) (corrosive, pulmonary edema) ndi perfluoroisobutylene (PFIB) (yopanda mtundu, yopanda fungo, ~ 10x poizoni kwambiri kuposa phosgene, antido). Komanso carbon monoxide, PFOA zotsalira, ndi kufufuza ma dioxin. Masks wamba wamba sagwira ntchito; gwiritsani ntchito zida zopumira zokha (SCBA). Zizindikiro zitha kuchedwa.

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.

Zopangira zomalizitsa pamwamba zomwe zimagwiritsidwa ntchito pansalu ya fiberglass pamaso pa PTFE zokutira ndizofunikira kwambiri kuti PTFE igwire ntchito ya nsalu yotentha kwambiri. Organosilane coupling agents amapanga milatho ya mamolekyulu pakati pa organic glass fiber ndi organic PTFE, kukulitsa mphamvu ya peel kuchokera pa <2 N/cm mpaka 4-8+ N/cm. Kuchiza koyenera kumathandizanso kukana kutentha (260 ° C+), magwiridwe antchito a dielectric, komanso kukana mankhwala. Nsalu yosasamalidwa imadzetsa delamination, kuphulika, ndi moyo waufupi wautumiki.

Calendering - kukanikiza nsalu yokutidwa ndi PTFE pakati pa zodzigudubuza zagalasi zotenthetsera pa 360-380 ° C - zimasintha kwambiri kapangidwe kapamwamba, kutulutsa katundu, kusakwanira, ndi magwiridwe antchito amakina. Amachepetsa roughness kuchokera ku Ra 0.5-1.0 μm kufika ku <0.05 μm, amasindikiza ma pinholes, amathandizira kukana kuvala, koma amachepetsa mphamvu ya misozi ndi kusinthasintha. Zofunikira pakutulutsa ma liner ndi kutchinjiriza kwamagetsi.
