I-Rubber o-rings EPDM 70shore-A FDA ibanga lokudla
● Ngokuvamile, ama-o-ring e-EPDM aziwa ngokukwazi ukumelana ne-ozone, ukukhanya kwelanga, nesimo sezulu, futhi anokuguquguquka okuhle kakhulu ezingeni lokushisa eliphansi, ukumelana kahle namakhemikhali (ama-asidi amaningi ahlanjululwayo nama-alkali kanye nezinyibilikisi ze-polar), kanye nempahla enhle yokufaka ugesi.
● Ama-o-ring e-EPDM angase futhi eze ngokuhlukahluka okubonakalayo kwensimbi kuyilapho egcina izimfanelo ezifanayo njengenhlanganisela evamile ye-EPDM o-ring.Amasongo o-EPDM ngokuvamile anombala omnyama, aneshalofu elihlala isikhathi eside.Isistimu Yokwelapha: I-Peroxide-Cured Standard EPDM o-ring compounds ngokuvamile i-sulfur-cured.
● Amakhompiyutha aphethwe ngesibabule anikeza izici eziguquguqukayo ezingcono kakhulu kodwa athambekele ekubeni abe lukhuni futhi abe nesethi yokucindezelwa okuphansi enamazinga okushisa aphezulu.Izingxube ze-EPDM o-ring ye-peroxide zinokumelana nokushisa okungcono kanye nesethi yokucindezela ephansi.Ihambisana nokusetshenziswa isikhathi eside, ikakhulukazi kumasistimu wepayipi embonini yokwakha, kodwa ibiza kakhulu futhi inzima kakhulu ukukhiqizwa kwe-DMEP eyenziwe ngesulfu.
● Ukuze uthole ulwazi olwengeziwe ngamasistimu okwelapha e-EPDM, sicela ukhululeke ukusithinta ukuze uthole ishidi lemininingwane.
● I-EPDM O-Ring Ibanga Lezinga lokushisa: Izinga lokushisa Elivamile Eliphansi: -55°C (-67°F)
● Izinga lokushisa Elijwayelekile Elijwayelekile: 125°C (257°F) Lisebenza Kahle Ngaphakathi:Utshwala Uketshezi lwamabhuleki ezimoto I-Ketones Nciphisa ama-asidi nama-alkali Amafutha e-Silicone namafutha Ashisayo afinyelela ku-204.4ºC (400ºF) Amanzi I-Phosphate ester esekelwe ku-hydraulic fluid I-Ozone, ukuguga, nesimo sezulu.
● ngaphezu kwalokho, i-EPM iyi-Copolymer ye-ethylene ne-propylene. I-EPDM iyi-terpolymer ye-ethylene ne-propylene enenani elincane le-monomer yesithathu (imvamisa i-diolefin) ukuze kuvumeleke ukuvuthwa ngesibabule.
● Ngokuvamile Irabha ye-Ethylene Propylene imelana kahle kakhulu ne-ozone, ukukhanya kwelanga nesimo sezulu, futhi inokuguquguquka okuhle kakhulu ezingeni lokushisa eliphansi, ukumelana kahle namakhemikhali (ama-asidi amaningi ancibilikayo, ama-alkali nezincibilikisi ze-polar), kanye nezakhiwo ezinhle zokuvala ugesi.
● I-Shore-A:Kusukela ku-30-90 ogwini-A noma yimuphi umbala ongayenza.
● SIZE:AS-568 wonke usayizi.
