Iyo PTFE firimu inokwanisa kusvika kuDIN4012 moto wekudzivirira mwero B1 mwero, tembiricha yekunyunguduka inogona kusvika 200 ℃, uye hazvisi nyore kubata moto.Uremu huremu, yakanaka ductility, yakakwirira compressive simba, kwete nyore kubvarura.Hupenyu hurefu hwesevhisi, isingasviki makore makumi matatu, inogutsa mbishi zvinhu zvekaviri-layer inobvisika denga zvivakwa.Nekuda kwekuti firimu rePTFE rinonamira cheni yemamorekuru nemaatomu efluorine, kugona kwayo kutora mamwe makemikari zvinhu hakuna kusimba.Munyika yakakura, pamusoro peiyo PTFE firimu inenge 185N/M, iyo mbishi yakaderera, uye haina kunamira.
Naizvozvo, PTFE mafirimu anonyanya kuratidza yakanaka yekuzvichenesa zvivakwa uye kuramba mvura.Teflon firimu ndiro raw material yeTeflon-yakavharwa girazi fiber.PTFE inogoneka zvakanyanya mune yakasimba mamiriro.Iyo yekupfeka inoda kunyungudutswa uye yozoiswa kune fiberglass.Tembiricha yekunyunguduka iri pamusoro pe400 ℃, uye frequency yekuputira inoda kanokwana kagumi.Mune chinongedzo ichi, iyo girazi fiber inoshanduka yero nekuda kwekupisa kwakanyanya, uye iyo inowanzo kupfekedza, inorema iyo ruvara.Naizvozvo, PTFE polytetrafluoroethylene firimu zvinhu ichangoburitsa ruvara rwebrown.Nekudaro, PTFE polytetrafluoroethylene firimu zvinhu zvinogona kugaya uye kutora ultraviolet mwaranzi kubva kuchiedza chezuva.
Teflon firimu haigoni kunama.Kubva pakuongororwa kwemaitiro ayo emuviri, pane zvikonzero zvakakosha zvinotevera: pasi pasi, hukuru hukuru hukuru, kunaka kwemakemikari kugadzikana kwekuongorora, chimiro chakanyanya symmetrical chepolytetrafluoroethylene firimu, uye yakaderera SP kukosha kwesolubility parameter ye polytetrafluoroethylene firimu.Iyo yepamusoro yakadzikira, uye tsigiro yepasi panzvimbo yakakosha kazhinji haina kukura.Iyo PTFE ine tension yepamberi ye118 madhigirii, yekumashure tension ye91 degrees, uye kupindirana kwechiso kwe104 degrees.Zvese zvigadzirwa zvakakura uye tension yemukati yakakwira.Rubrication range idiki, kureva kusanamira zvakanaka uye kusanamira kwakakwana.Wet Teflon epurasitiki firimu, saka hapana yakanaka adhesion kuti Teflon tsanga saizi, yakanaka analytical kemikari kugadzikana, teflon kuzvimba uye kunyunguduka zvose kupfuura crystalline mapolymers haigoni kukosheswa paTeflon epurasitiki firimu yakaoma polymer macromolecular cheni pamusoro.
