Iwo Akazadzwa mamakisi ePTFE anogona kusanganiswa & akagadziridzwa kune chaiwo sevhisi mamiriro & mashandisirwo.Yakazadzwa PTFEmamakisi ane chaiwo zvivakwa kuvandudzwa kwakavakirwa pakuzadza, mhando yekuzadza & muzana yekuzadza.
Mechanical properties
Iyo yekumanikidza inokambaira maitiro ePTFE yakazadzwa ndechimwe chezvinhu zvakakosha kune mugadziri uye mushandisi.
Mukuenzanisa nePTFE isina kuzadza iyo compressive modulus ye PTFE yakazadzwa yakakura uye saka, nekuda kwekushushikana kwakafanana, kuderera kwakadzika kuchaitika.Musiyano uyu unodzikira, zvisinei, sezvo tembiricha dzinokwira uye kuita kwekumanikidza kwePTFE isina kuzadzwa uye yakazadzwa ichiswedera pedyo pa200 ° C (392 ° F).Chikonzero chinenge chiri chokwadi chekuti kuderedzwa kwakawanda kweiyo compressive modulus yePTFE matrix inodarika rutsigiro rwakapihwa nekusarudzika kugoverwa kwezvimedu zvekuzadza.
Magetsi zvinhu
Iyo yekuwedzera yemafiller ine mucherechedzo wakajeka pane zvemagetsi zvivakwa zvakare.Kunyanya, graphite - uye kabhoni yakazadzwa makomisheni inogona kunge iine yakakwira conductivity, iyo inogona kubatsira kuparara kweiyo static charges mumashandisirwo ayo aya ari dambudziko.
Yakazadzwa PTFE musanganiswa wezvinhu, uye voids - kunyangwe idiki sei - inogara iripo: sekunge ine zvinhu zvese zvine porous, zvivakwa zvinoenderana nemhando yezvakatipoteredza uye yekusvibisa kusingafungidzirwe.Iwo emagetsi zvivakwa haana mutsauko uye anonyanya kutsamira pane kwezvakatipoteredza humidity.
Thermal properties
Kuwedzera kwekupisa kwemafuta akawanda kuduku pane yePTFE uye sezvo kuwedzera kwemusanganiswa kuchave kune imwe nzvimbo pakati peiyo yezvikamu zviviri, mitsara yePTFE yakazadzwa inowedzera zvishoma pane PTFE isina kuzara.Munguva yekugadzira mamwe mafirita, kunyanya mafiber uye maplatelet, anove akasarudzika (sezvinoita zvimedu zvePTFE kusvika padiki dhigirii).Mhedzisiro yacho ndeyekuti mamwe makomisheni ane kuwedzera kwakasiyana kwakasiyana mumatanho anofambirana uye perpendicular kune nzira yekuumbwa.
Thermal conductivity yePTFE yakaderera zvakanyanya, zvichiita kuti ive yakanaka yekupisa insulating zvinhu.Mazhinji mafirita, kunyanya simbi uye simbi oxides, ane high thermal conductivity, asi kazhinji iwo anonyatso kuvharidzirwa nePTFE kuitira kuti conductivity yemakomponi ichiri yakaderera.
