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 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.

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 (PTFE membrane material) ndi chisankho choyambirira pamamangidwe olimba. Ubwino waukulu: zaka 30+ za moyo wapanja, kudziyeretsa pawokha (madzi amvula amatsuka dothi), kufalitsa kuwala kofewa (6-13%), Kuyeza moto kwa Gulu A, mphamvu zonga chitsulo zosakwana 1.5 kg/m². Amagwiritsidwa ntchito m'mabwalo amasewera, ma eyapoti, ndi nyumba zodziwika bwino padziko lonse lapansi.

Nsalu ya PTFE yotentha kwambiri imapereka kukana kwapadera kwamankhwala, kupirira ma asidi amphamvu, alkalis, zosungunulira za organic, ndi mpweya wowononga. Nkhaniyi ikufotokoza za zinthu zake zosamva, zolepheretsa (zitsulo za alkali zosungunuka, zopangira mphamvu za fluorinating), ndi zinthu zazikulu monga kutentha, kukhazikika, komanso kupsinjika kwamakina.

Kulowetsedwa kwa PTFE sikungokhala ndi nsalu za fiberglass. Nkhaniyi ikuwonetsa magawo asanu ndi awiri amtundu wina - aramid, carbon fiber, PBI, porous metal, graphite, asbestos (ochotsedwa), ndi zodzaza ndi ceramic - ndi machitidwe awo, ubwino, malire, ndi ntchito zazikulu.

Nkhaniyi ikufotokoza chifukwa chake nsalu ya fiberglass yopanda alkali ndiye gawo lapansi lokondedwa la nsalu za PTFE zotentha kwambiri. Imakhudza kulumikizana kwamankhwala kudzera pa ma silane coupling agents ndi zinthu zofunika kwambiri monga kukhazikika kwamafuta, kukhazikika kwa mawonekedwe, komanso kukana kwa dzimbiri - kuwonetsetsa kuti zikugwira ntchito kwanthawi yayitali m'malo ovuta.
