Cabbirro kala duwan oo caag ah hnbr epdm nbr 70 shaabadood oo xidhidh oring o-ring o-ring
O-rings ayaa si weyn loogu isticmaalaa warshado kala duwan si ay u abuuraan shaabad u dhaxaysa labada dusha sare.Doorashada walxaha O-ring waxay ku xiran tahay codsiga iyo deegaanka lagu isticmaali doono. Waa kuwan qaar ka mid ah qalabka caadiga ah ee loo isticmaalo O-rings:
Nitrile (NBR): Tani waa walxo caan ah oo loogu talagalay O-rings sababtoo ah caabbinta aadka u fiican ee saliidda, shidaalka, iyo biyaha.Waxay u adkeysan kartaa heerkulka ilaa 100 ° C.
Viton (FKM): Viton waa elastomer-ka fluorocarbon kaas oo leh iska caabin kiimiko oo heer sare ah, gaar ahaan heerkul sare iyo kiimikooyin adag.Waxay u adkeysan kartaa heerkulka ilaa 200 ° C.
Silikoon (VMQ): Silikoon O-rings ayaa caan ku ah dabacsanaan aad u wanaagsan iyo iska caabin heerkul aad u sarreeya, mid sare iyo mid hooseba.Waxay u adkeysan karaan heerkulka -60 ° C ilaa 200 ° C.
EPDM waa caag synthetic ah oo iska caabin heer sare ah u leh cimilada, ozone, iyo fallaadhaha UV.Caadi ahaan waxaa loo isticmaalaa codsiyada dibadda waxayna u adkeysan kartaa heerkulka ilaa 150 ° C.
Neoprene: Neoprene O-rings waxaa lagu yaqaan caabbinta wanaagsan ee saliidda, cimilada, iyo ozone.Waxay u adkeysan karaan heerkulka ilaa 100 ° C.
