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.

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.

Kachulukidwe kakachulukidwe ka magalasi a fiberglass kumatsimikizira kuti PTFE imakhala yotentha kwambiri. Kuchulukirachulukira kumawonjezera kulimba kwamphamvu komanso kusalala kwa pamwamba koma kumachepetsa mphamvu yong'ambika (kupindika kwa U-curve), kusinthasintha, ndi kulowa mkati mwa zokutira. Kachulukidwe mulingo woyenera kulowa, kukana misozi, kusinthasintha, ndi kumaliza pamwamba. Kachulukidwe kakang'ono kamagwirizana ndi kupindika kwamphamvu; kachulukidwe kakang'ono kosamata ndi kutsekereza.

Calendering – kukanikiza PTFE- TACHIMATA nsalu pakati pa chotenthetsera kalirole rollers pa 360-380 ° C - amasintha mochititsa chidwi morphology pamwamba, kumasula katundu, impermeability, ndi makina ntchito. 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.

Kuyeretsa ndi kukonza moyenera kumakulitsa moyo wa nsalu za PTFE zotentha kwambiri. Chotsani mukatha kugwiritsa ntchito komanso mukazizilitsa. Gwiritsani ntchito maburashi ofewa, zotsukira zopanda ndale, kapena mowa popaka madontho. Musagwiritse ntchito zidulo zolimba/ma alkali, bulichi, kapena zopalira zitsulo. Kupaka mafuta okhazikika a silicone kumachepetsa kuvala. Tsatirani malangizowa kuti mupewe kuwonongeka kwa zokutira.

Nsalu zotentha kwambiri za PTFE ndi nsalu za silikoni zonse zimagwiritsa ntchito nsalu za fiberglass ngati maziko koma zimasiyana pakuyatira (PTFE resin vs silicone raba). PTFE imapambana pakusagwira ndodo, kukana kuvala, komanso kukana mankhwala mpaka 260°C. Nsalu ya silicone imapereka kusinthasintha kwapamwamba, kutsekemera kwa magetsi, ndi kukana moto (mpaka 230 ° C). Sankhani malinga ndi zomwe mumakonda.
