I-Rubber o-rings EPDM 70shore-A Ibanga lokudla le-FDA
I-Rubber o-rings EPDM 70shore-A Ibanga lokudla le-FDA
● Ngokuvamile, ama-o-ring e-EPDM aziwa ngokukwazi ukumelana ne-ozone, ukukhanya kwelanga, kanye nesimo sezulu, futhi ayakwazi ukuguquguquka okuhle kakhulu ezingeni lokushisa eliphansi, ukumelana kahle namakhemikhali (ama-acid amaningi ahlanjululwe kanye nama-alkali kanye nezinyibilikisi ze-polar), kanye nokufakwa kahle kukagesi. impahla.
● Ama-o-ring e-EPDM angase abe nokuhlukahluka okubonakalayo kwensimbi kuyilapho egcina izimfanelo ezifanayo njengenhlanganisela evamile ye-EPDM o-ring.Ama-o-o-EPDM ngokuvamile anombala omnyama, anempilo ehlala isikhathi eside. I-Cure System: Peroxide- I-Cured Standard EPDM o-ring compounds ivamise ukulapheka ngesulfure.
● Izinhlanganisela ezenziwe ngesulfure zinikeza izici eziguquguqukayo ezingcono kodwa zijwayele ukuba lukhuni futhi zinesethi yokucindezelwa okuphansi enamazinga okushisa aphezulu.Izinhlanganisela ze-EPDM o-ring ye-peroxide zinokumelana nokushisa okungcono kanye nesethi yokucindezela ephansi.Ihambisana nokusetshenziswa isikhathi eside , ikakhulukazi kuma-hose systems embonini yokwakha, kodwa kubiza kakhulu futhi kunzima kakhulu ukukhiqiza kunezingxube ze-EPDM o-ring o-ring compounds.
● 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-acids nama-alkali Amafutha e-Silicone namafutha Ashisayo afinyelela ku-204.4ºC (400ºF) Amanzi Phosphate ester asekelwe ku-hydraulic fluids 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.
