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 pa 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.

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.

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.

Nsalu ya PTFE yotentha kwambiri imapereka kukana kwapadera kwamankhwala, kupirira ma asidi amphamvu, alkalis, zosungunulira za organic, ndi mpweya wowononga. Nkhaniyi imafotokoza mwatsatanetsatane za zinthu zomwe zimagonjetsedwa, zolepheretsa (zitsulo za alkali zosungunuka, zopangira mphamvu za fluorinating), ndi zinthu zazikulu monga kutentha, kukhazikika, ndi kupsinjika kwa makina.
