Rubber o-mhete EPDM 70shore-A FDA chikafu chegiredhi
● Kazhinji, EPDM o-rings dzinozivikanwa kuti dzine kupikisa kwakanakisisa ku ozone, chiedza chezuva, uye mamiriro ekunze, uye ine kushanduka kwakanaka kwazvo pakudzika kwekushisa, kupikisa kwakanaka kwemakemikari (akawanda dilute acids uye alkalis pamwe chete ne polar solvents), uye yakanaka magetsi ekudzivirira pfuma.
● EPDM o-rings inogonawo kuuya mune imwe metal inoonekwa kusiyana ichichengetedza unhu humwechete sehuwandu hweEPDM o-ring compound.EPDM o-rings inowanzova yakasviba muvara, ine hupenyu hurefu hunogara kwenguva refu.Cure System: Peroxide-Cured Standard EPDM o-ring compounds inowanzoitwa sulfur-cured.
● Sulfur-cured compounds inopa zvinhu zviri nani zvinogadziriswa asi zvinonyanya kuoma uye zvine yakaderera compression yakagadzirirwa nepamusoro tembiricha.Peroxide-yakagadziriswa EPDM o-ring compounds ine zviri nani kupisa kupisa uye kuderera kwekugadzirisa kwekugadzirisa.Inopindirana nekushandiswa kwenguva refu, kunyanya kune zvirongwa zvepombi mumhizha yekuvaka, asi inodhura uye yakaoma zvikuru pakugadzirwa kwesarufa yeDMEP.
● Kuti uwane rumwe ruzivo nezve EPDM kurapa masisitimu, ndapota wakasununguka kutibata kuti uwane ruzivo rwebepa.
● EPDM O-Ring Temperature Range: Standard Low Temp: -55°C (-67°F)
● Standard High Temp: 125°C (257°F) Inoita Zvakanaka Mu: Doro Mota yebhureki fluid Ketones Dilute acids uye alkalis Silicone oiri negirisi Kupfungaira kusvika 204.4ºC (400ºF) Mvura Phosphate ester based hydraulic fluids Ozone, kuchembera, uye mamiriro ekunze.
● chii chimwe, EPM iCopolymer ye ethylene uye propylene. EPDM inonzi terpolymer ye ethylene uye propylene ine kashoma ketatu monoma (kazhinji diolefin) kubvumira vulcanization nesarufa.
● Kazhinji Ethylene Propylene Rubber inokwanisa kurwisana neozone, chiedza chezuva uye mamiriro ekunze, uye inokwanisa kushanduka zvakanaka pakudziya kwakaderera, makemikari anopikisa akawanda (akawanda dilute acids, alkalis & polar solvents), uye zvinhu zvakanaka zvekudzivirira magetsi.
● Shore-A:Kubva 30-90 kumahombekombe-A chero ruvara runogona kuita.
● SIZE:AS-568 saizi yese.
