Kodi chophimba cha Teflon powder ndi chiyani?
M'ndandanda wazopezekamo
Teflon ufa zokutira ndi mtundu wolembetsedwa wa zokutira za fluoropolymer ndi DuPont, makamaka zochokera ku fluororesins monga PTFEFEP, ndi ETFE. Zimaphatikiza zabwino zazikulu za fluoromaterials-kukana kwa dzimbiri, zinthu zopanda ndodo, komanso kukana kutentha kwambiri-ndi ntchito zambiri.
Magulu Akuluakulu
- PTFE Mtundu: Ndi kukana kwambiri kutentha kwapamwamba (mpaka 260 ° C) komanso kocheperako kocheperako kwambiri, imayang'ana kwambiri magwiridwe antchito osamata, oyenera pazochitika zomwe zimafuna kutulutsa kwakukulu.
- Mtundu wa FEP: Kuchita bwino kwambiri poyerekeza ndi PTFE, yokhala ndi zokutira zowoneka bwino komanso zosalala zolimba kukana kwamankhwala, zabwino pazogwirira ntchito zomwe zimafuna kukhazikika komanso kukana dzimbiri.
- ETFE Mtundu: Imalinganiza kukana kwa nyengo, kutheka, ndi mphamvu zamakina, ndi kutentha kwanthawi yayitali mpaka 150 ° C, koyenera zida zomangira zovuta komanso ntchito zakunja.
- Mtundu wa PFA: Kuphatikiza PTFE's mkulu-kutentha kukana ndi processability FEP, angathe kugwira ntchito khola pansi Kutentha mobwerezabwereza popanda kuwola, oyenera mkulu-chiyero ndi mkulu-kutentha ntchito zikhalidwe.
Makhalidwe Ofunika Kwambiri
- Kusamamatira kwenikweni: Kutsika kwambiri pamtunda, kusamamatira ku chinthu chilichonse, kumapangitsa kuyeretsa kosavuta.
- Kulekerera kutentha kwakukulu: Kugwira ntchito mokhazikika mkati mwa -200 ° C mpaka 260 ° C (kusiyana pang'ono ndi mtundu), kugonjetsedwa ndi kugwedezeka kwapamwamba ndi kutentha kochepa.
- Kukana kwamphamvu kwa dzimbiri: Imalimbana ndi kukokoloka kwa zidulo zolimba, ma alkalis, zosungunulira organic, ndi zinthu zina, kudzitamandira kukhazikika kwamankhwala.
- Low friction coefficient: Imachepetsa kuvala kwa zinthu, imathandizira magwiridwe antchito a zida, ndikuwonjezera moyo wautumiki.
- Kusamalira chilengedwe ndi chitetezo: Utsi wopanda zosungunulira mu mawonekedwe a ufa, motsatira miyezo ya chilengedwe. Chophimbacho ndi chopanda poizoni komanso chopanda fungo, ndipo mitundu ina imakumana ndi ziphaso zotetezedwa ndi FDA.
Milandu Yodziwika Yogwiritsa Ntchito
- Kukonza chakudya: Ziwaya zopanda ndodo, nkhungu zophikira, malamba otumizira chakudya, zoumba chokoleti zimafa.
- Makina a mafakitale: Ma bearings, magiya, mavavu, mapampu, ndi zomangira zamkati zamagetsi zamagetsi.
- Electronics ndi Semiconductors: Zida za Semiconductor, ma tray ophikira ozungulira, ndi zokutira zotchingira pazida zamagetsi.
- Zipangizo zamankhwala: Zida zopangira opaleshoni, zolumikizira machubu olowetsa, ndi nkhungu zamankhwala.
- Mphamvu zatsopano: mafelemu a PV module, zomangira masamba amphepo, ndi zida zopangira batire la lithiamu.
Kubwezeretsanso kwabwino kwambiri kwa zinthu zomwe zikuyembekezerani za antiadherencia, temperatura, desgaste, buena adherencia al sustrato
