Irabha o-amakhonkco EPDM 70shore-A FDA ibakala lokutya
● Ngokubanzi, i-EPDM o-rings zaziwa ngokuba nokumelana okugqwesileyo kwi-ozone, ukukhanya kwelanga, kunye nemozulu, kwaye ikwazi ukuguquguquka okuhle kakhulu kwiqondo lokushisa eliphantsi, ukuchasana kakuhle kweekhemikhali (amaninzi e-dilute acids kunye ne-alkali kunye nezinyibilikisi ze-polar), kunye nepropati efanelekileyo yokugquma umbane.
● I-EPDM i-o-rings ingaphinda ifike kwi-metal detectable variation ngelixa igcina iimpawu ezifanayo kunye ne-EPDM o-ring compound.EPDM o-rings zivame ukuba mnyama ngombala, kunye ne-shelf ehlala ixesha elide.I-Cure System: I-Peroxide-Cured Standard EPDM i-o-ring compounds idla ngokunyangwa isulfure.
● Iikhompawundi zesulfure zibonelela ngeempawu eziguquguqukayo ezingcono kodwa ziyakwazi ukuqina kwaye zibe ne-inferior compression set with high temperatures.Peroxide-cured EPDM o-ring compounds have better heat resistance and low compression set.It ithobelana nokusetyenziswa kwexesha elide, ngakumbi kwiinkqubo ze-hose kushishino lokwakha, kodwa ibiza kakhulu kwaye inzima kakhulu kwimveliso ye-sulfur DMEP.
● Ukuze ufumane inkcazelo engakumbi ngeenkqubo zokunyanga ze-EPDM, nceda ukhululeke ukuqhagamshelana nathi ukuze ufumane iinkcukacha zephepha.
● I-EPDM O-Ring Uluhlu lobushushu: Ubushushu obuPhantsi obuMgangatho: -55°C (-67°F)
● Ubushushu obuMgangatho obuPhakamileyo: 125°C (257°F) Isebenza Kakuhle Kwi:Alcohols Automotive brake fluid Ketones Dilute acids and alkalis Silicone oils and greases Umphunga ukuya kuma 204.4ºC (400ºF) Amanzi Phosphate ester based hydraulic fluids Ozone, ukuguga, kunye nemozulu.
● ngaphezu koko, i-EPM yiCopolymer ye-ethylene kunye nepropylene. I-EPDM yi-terpolymer ye-ethylene kunye ne-propylene kunye nenani elincinci le-monomer yesithathu (ngokuqhelekileyo i-diolefin) ukuvumela i-vulcanization ngesulfure.
● Ngokubanzi Irabha ye-Ethylene Propylene inamandla okumelana ne-ozone, ukukhanya kwelanga kunye nemozulu, kwaye inokuguquguquka okuhle kakhulu kwiqondo lobushushu eliphantsi, ukuxhathisa okulungileyo kwiikhemikhali (ezininzi ze-acids ezixubileyo, i-alkalis & nezinyibilikisi ze-polar), kunye neempawu ezilungileyo zokugquma umbane.
● Unxweme-A:Ukususela kwi-30-90 yolwandle-A nawuphi na umbala onokuyenza.
● SIZE:AS-568 bonke ubukhulu.
