Zodzaza PTFE Properties

Magiredi Odzaza a PTFE amatha kuphatikizidwa & kusinthidwa makonda pamikhalidwe ndi ntchito zina.Wodzaza PTFEmagiredi ali ndi kuwongolera kwapadera kutengera zodzaza, mtundu wa filler & kuchuluka kwa zodzaza.

Zimango katundu

Khalidwe lopumira lodzaza PTFE ndi chimodzi mwazinthu zofunika kwambiri kwa wopanga ndi wogwiritsa ntchito.

Poyerekeza ndi PTFE yosadzazidwa ndi compressive modulus ya PTFE yodzaza ndi yaikulu choncho, chifukwa cha kupsinjika komweko, kutsika kochepa kudzachitika.Kusiyanaku kumachepa, komabe, kutentha kumakwera komanso kugwira ntchito kwa PTFE yosadzazidwa ndi kudzazidwa kumayandikira 200 ° C (392 ° F).Chifukwa chake ndi pafupifupi kuti kuchepetsedwa kwapang'onopang'ono kwa matrix a PTFE kumaposa chithandizo choperekedwa ndi kugawa mwachisawawa kwa tinthu tating'onoting'ono.

Mphamvu zamagetsi

Kuphatikiza kwa ma fillers kumakhudzanso kwambiri mphamvu zamagetsi.Makamaka, ma graphite - ndi mankhwala odzaza kaboni akhoza kukhala ndi ma conductivity apamwamba kwambiri, omwe angathandize kutayika kwa zolipiritsa zosasunthika pamapulogalamu omwe ali ndi vuto.

Wodzazidwa PTFE ndi chisakanizo cha zipangizo, ndi voids - ngakhale ang'onoang'ono - amakhalapo nthawi zonse: monga ndi zipangizo porous, katundu zimadalira chikhalidwe cha chilengedwe ndi kuipitsidwa mwangozi.Mphamvu zamagetsi ndizosiyana ndipo zimadalira kwambiri chinyezi cha chilengedwe.

Thermal katundu

Kukula kwamafuta amafuta ambiri ndi ocheperako a PTFE ndipo popeza kukulitsa kophatikiza kudzakhala kwinakwake pakati pa zigawo ziwirizi, zodzaza PTFE zimakulitsa zochepa kuposa PTFE yosadzaza.Pakupanga zodzaza zina, makamaka ulusi ndi mapulateleti, amakhala okonda kwambiri (monga tinthu tating'onoting'ono ta PTFE).Chotsatira chake ndi chakuti zinthu zina zimakhala ndi kufalikira kosiyana kwambiri m'njira zofananira komanso zozungulira pozungulira.

The matenthedwe madutsidwe wa PTFE ndi otsika kwambiri, kupanga zabwino matenthedwe insulating zakuthupi.Ma fillers ambiri, makamaka zitsulo ndi zitsulo oxides, ndi mkulu matenthedwe madutsidwe, koma ambiri iwo bwino encapsulated ndi PTFE kuti madutsidwe wa mankhwala akadali otsika.
