❖ 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 kuti chifanane), gawo lapansi khalidwe (yokhotakhota chitsanzo, chisanadze mankhwala), ndi chilengedwe kupanga (20-25% R <60% <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 (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.

Nsalu yopumira kwambiri ya PTFE yotentha kwambiri imaphatikiza zinthu zopanda ndodo, kukhazikika kwamafuta, komanso kuthekera kwa mpweya. Nkhaniyi ikuwunika momwe imagwirira ntchito pakuyanika nsalu, kukonza chakudya, kupanga zinthu zambiri, zamagetsi, zotumiza mpweya, kuteteza chilengedwe, ndi zida zomangira.

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.

Momwe Mungasankhire Chovala Chovala Choyenera cha PTFE cha Zomangamanga? Posankha nsalu yabwino kwambiri ya PTFE yogwiritsidwa ntchito pomanga, muyenera kuganizira zofunikira za polojekitiyi, momwe zimagwirira ntchito, komanso momwe zidzakhudzire dziko lapansi. Wosanjikiza wa polytetrafluoroethylene ndiwothandiza kwambiri poteteza zinthu,

Chitsogozo Chosankha Chovala Chovala cha Fiberglass cha PTFE cha Kutentha Kwambiri KusindikizaKuti musankhe nsalu yabwino kwambiri ya PTFE yokutidwa ndi fiberglass kuti mutseke ntchito pa kutentha kwambiri, muyenera kudziwa mbali zake zazikulu zogwirira ntchito, zosowa zabizinesi yanu, ndi zinthu zomwe wogulitsa akugulitsa. Wapadera wosakanizidwa
