Dzina: PTFE ulusi wosokera
Zida Zokometsedwa: PTFE
Kulemera kwake: 200-1000g
Zambiri: 400D-2700D
Mtundu: White, Black, ndi makonda
Ntchito:Nthawi zambiri amagwiritsidwa ntchito m'mapaipi, zotengera, mapampu, ma valve, ndi makina a radar, zida zoyankhulirana zothamanga kwambiri, komanso zida zamawayilesi zomwe zimafunikira magwiridwe antchito apamwamba.
Ntchito yamalonda:Kusindikiza kwa gasket ndi zida zopaka mafuta zomwe zimagwira ntchito pama media osiyanasiyana.
1.Chemical resistance:
PTFE ali kwambiri kukana dzimbiri mankhwala, monga mu anaika sulfuric acid, hydrochloric acid, ndi asidi nitric.Ngakhale atawiritsa mu aqua regia, kulemera kwake ndi katundu wake sizisintha, ndipo pafupifupi osasungunuka mu zosungunulira zambiri, zimasungunuka pang'ono mu peralkanes (pafupifupi 0.1g/100g) pamwamba pa 300 °C.
2.Kukana kwanyengo:
PTFE sichimamwa chinyezi, sichikhoza kuyaka, ndipo imakhala yokhazikika ku mpweya ndi kuwala kwa ultraviolet, choncho imakhala ndi nyengo yabwino kwambiri.
3.Mechanical properties:
PTFE amakhalabe kwambiri makina katundu mu lonse kutentha osiyanasiyana -196 kuti 260 ° C. Mmodzi wa makhalidwe a perfluorocarbon ma polima ndi kuti si kukhala Chimaona pa kutentha otsika.Kachulukidwe wa PTFE ndi wokulirapo, womwe ndi 2.14-2.20g/cm3, samayamwa madzi, ndipo kuchuluka kwa mayamwidwe amadzi ndikochepera 0.01%.
PTFE ndi yofewa ndi yofooka polima, kukopana pakati pa macro-molecule ndi yaying'ono, ndipo kuuma, kuuma ndi mphamvu ndizochepa, ndipo zidzapunduka pansi pa kupsinjika kwa nthawi yaitali.
