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, zotsalira za PFOA, 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 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.

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.

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.

Fiberglass weave pattern - plain, twill, kapena satin - imakhudza kwambiri PTFE katundu wa nsalu yotentha kwambiri. Satin weave imapereka mphamvu zong'ambika kwambiri (2-3x plain) komanso kusinthasintha, koyenera kupindika mwamphamvu. Plain weave imapereka kukhazikika kwapamwamba kwambiri komanso kumamatira kwa peel, koyenera kugwiritsa ntchito static. Twill imalinganiza zinthu zonse kuti zigwiritsidwe ntchito.

❖ kuyanika yunifolomu wa PTFE mkulu kutentha nsalu anatsimikiza ndi zinthu zinayi: ❖ kuyanika chiphunzitso (tinthu kukula 0.15-0.35 μm, mamasukidwe akayendedwe, okhutira olimba), ❖ kuyanika & sintering ndondomeko (tsamba ❖ kuyanika ankakonda kufanana), gawo lapansi khalidwe (yokhotakhota chitsanzo, chisanadze mankhwala), ndi kupanga chilengedwe (20-25% R <60]). Dip + blade kuphatikiza njira yolowera ndi kusalala kwa pamwamba.
