Rubber o-impeta EPDM 70shore-A FDA ibiryo
Rubber o-impeta EPDM 70shore-A FDA ibiryo
● Mubisanzwe, EPDM o-impeta izwiho kuba ifite imbaraga zo guhangana na ozone, urumuri rwizuba, nikirere, kandi ifite imiterere ihindagurika cyane mubushyuhe buke, imiti irwanya imiti myinshi (acide acide acide na alkalis hamwe na solide ya polar), hamwe nubutunzi bwiza bwamashanyarazi.
● EPDM o-impeta irashobora kandi kuza muburyo butandukanye bwerekana ibyuma mugihe hagumanye imico imwe nki rusange rusange ya EPDM o-impeta.
● Ibicuruzwa byakize bya sufuru bitanga ibintu byoroshye guhinduka ariko bikunda gukomera no kugira compression yo hasi yashyizweho nubushyuhe bwo hejuru.Imvange ya EPDM o-ring ivanze ifite ubushyuhe burwanya ubukana hamwe na compression yo hasi.Bihuye nikoreshwa ryigihe kirekire, cyane cyane kuri sisitemu ya hose munganda zubaka, ariko birahenze kandi biragoye kubyara umusaruro uva kuri sulfure o-yakize.
● 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 (ubusanzwe ni diolefine) kugirango yemere kwanduzwa 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.
