PTFEndi TFM amagwiritsidwa ntchito ngati mvuvu muzambiri zolimbana ndi dzimbiri - makamaka ma organic compounds, ma acid, ndi mchere - komanso kutentha kwambiri komanso kuyeretsa kwakukulu.Onsewa amasonyeza khalidwe lopanda ndodo, ndipo ali ndi kutentha kosiyanasiyana kofananako.Komabe, pali kusiyana kwakukulu pakati pawo, chifukwa TFM imaphatikiza mikhalidwe yabwino kwambiri ya PTFE ndi PFA.TFM ndiye mvuvu yomwe mungasankhe mukafuna mpweya wochepa kwambiri, moyo wautali wotopa, komanso kutha kwapamwamba.
PTFE yosinthidwa ndi mtundu wa PTFE womwe uli ndi kuthekera kwatsopano kuwonjezera pa mawonekedwe a katundu omwe amagwirizana ndi zida za PTFE.
PTFE yosinthidwa ili ndi mikhalidwe yatsopano kapena yabwinoko kuposa PTFE yokhazikika:
Mbali zake zimakhala zosalala, komanso zocheperapo - zigawo zake zimakhala zaukhondo chifukwa sizitha kutchera zowononga Zochepa zazing'ono zopanda kanthu zimapatsa mphamvu kuti zisapitirire Kutalikirana ndi moyo wautali kuposa PTFE. njira zosiyanasiyana zowotcherera kutentha ndi kupanikizika pang'ono)Zitsanzo za Containers & Tubes zopangidwa pogwiritsa ntchito APT's Modified PTFE Fusing & Machining Processes
PTFE imayimira Polytetrafluoroethylene, fluorocarbon thermoplastic yomwe yagwiritsidwa ntchito kwambiri pazauinjiniya ndipo imadziwika kwambiri chifukwa chokhala ndi coefficient yotsika kwambiri ya kukangana kulikonse.Amadziwikanso kuti polima, Dyneon TM, 1,1,2,2-tetraflouroethene kapena 1,1,2,2-tetraflouroethylene.
Monga tanenera kale, PTFE ndi imodzi mwa ma polima amphamvu kwambiri omwe amapezeka (Chemical Resistance Chart).Ili ndi kutentha kosalekeza kogwiritsa ntchito kuyambira -200 ° C mpaka 250 ° C ndipo imalimbana ndi kuyamwa kwamadzi.Kuonjezera apo, ili ndi khalidwe lodana ndi zomatira lomwe limatsutsana ndi zolimba, zomwe zimapangitsa kuti zikhale zosavuta ku CIP (Clean In Place).M'malo mwake, pali magulu osiyanasiyana a PTFE omwe amavomerezedwa ndi FDA.
PTFE yosinthidwaimatchedwa polytetrafluoroethylene, ndi dzina lamalonda la Polyflon.Ndi kuphatikiza kochititsa chidwi kwa PTFE ndi PFA (Perfluoroalkoxy), yomwe imadziwika chifukwa cha makina ake apamwamba kwambiri.
Monga PTFE, TFM ndi inert mankhwala ndipo ali osiyanasiyana osiyanasiyana kutentha ntchito mosalekeza, komanso kukana mofanana mayamwidwe madzi.Komanso amakhalabe zambiri PTFE a sanali ndodo makhalidwe.
TFM ilinso ndi chiwongola dzanja chokwera pang'ono, koma zowoneka bwino zotopa ndikuwonetsa kuchira bwino kupsinjika.Kuphatikiza apo, ndikosavuta kuwotcherera kuposa PTFE ndikulemera pang'ono.TFM imalimbananso ndi kukhumudwa komanso kukalamba.
Chinthu chimodzi chomwe chimapangitsa TFM kukhala yapadera ndi kachulukidwe kapangidwe ka maselo.Izi zimapangitsa kuti pakhale kutsika kwambiri kwa mpweya wodutsa mumtundu womwewo wa zinthu poyerekeza ndi PTFE.Khalidweli ndi lofunika kwambiri likagwiritsidwa ntchito pamalo owononga kwambiri.Ndi kapangidwe kake kakang'ono ka mamolekyu, TFM imaperekanso kumaliza kosalala kwa PTFE.Komanso, monga PTFE, pali magulu osiyanasiyana a TFM omwe avomerezedwa ndi FDA.
