Rubber o-impeta EPDM 70shore-A ibiryo bya FDA
Rubber o-impeta EPDM 70shore-A ibiryo bya FDA
● Mubisanzwe, EPDM o-impeta izwiho kuba ifite imbaraga zo guhangana na ozone, urumuri rwizuba, nikirere, kandi ifite imiterere ihindagurika cyane mubushyuhe buke, irwanya imiti myiza (acide nyinshi ya dilute na alkalis kimwe na solide ya polar), hamwe no gukwirakwiza amashanyarazi neza; umutungo.
● EPDM o-impeta irashobora kandi kuza mubyuma bitamenyekana mugihe ugumana imico imwe nki rusange rusange ya EPDM o-impeta. Ikiza gisanzwe cya EPDM o-impeta isanzwe ikize sulfure.
● Ibicuruzwa bivangwa na sufuru bitanga ibintu byoroshye guhinduka ariko bikunda gukomera kandi bikagira compression yo hasi yashyizweho nubushyuhe bwinshi. , cyane cyane kuri sisitemu ya hose mubikorwa byubwubatsi, ariko bihenze kandi biragoye kubyara umusaruro kuruta EPDM o-ring ivanze na sulfuru.
● Kubindi bisobanuro kuri sisitemu yo gukiza EPDM, nyamuneka twandikire kugirango ubone ibisobanuro birambuye.
● EPDM O-Impeta Ubushyuhe Urwego: Ubushyuhe Buke: -55 ° C (-67 ° F)
Temp Ubushyuhe bwo hejuru: 125 ° C (257 ° F) Bikora neza Muri: Alcohols Automotive feri fluid Ketones Dilute acide na alkalis Amavuta ya Silicone hamwe namavuta Amashanyarazi agera kuri 204.4ºC (400ºF) Amazi ya Fosifate ester ashingiye kumazi ya hydraulic Ozone, gusaza, hamwe nikirere .
Ikirenzeho, EPM ni Copolymer ya Ethylene na propylene.EPDM ni terpolymer ya Ethylene na propylene hamwe na monomer ya gatatu ya monomer ya gatatu (ubusanzwe ni diolefine) kugirango yemere guterwa na sulfuru.
Muri rusange Ethylene Propylene Rubber ifite imbaraga zo guhangana na ozone, urumuri rwizuba hamwe nikirere, kandi ifite imiterere ihindagurika cyane mubushyuhe buke, irwanya imiti myiza (acide nyinshi ya dilute, alkalis & polar solvent), hamwe nuburyo bwiza bwo gukwirakwiza amashanyarazi.
Ore Inkombe-A:Kuva 30-90 inkombe-A ibara ryose rishobora gukora.
● SIZE:AS-568 ingano yose.
