O-rings waxaa loo isticmaali karaa codsiyo kala duwan sababtoo ah waxay ka samaysan yihiin qalab kala duwan.O-rings waxaa badanaa laga sameeyaa caag, ama si gaar ah polymer/elastomer.Polymers-yadan waxaa sida caadiga ah lagu daaweeyaa vulcanization, taasoo keenta walxo caag ah oo xooggan, adkeysi leh oo aad u dheer.
P-rings waa naqshadda farsamada ee ugu caansan ee xirmooyinka sababtoo ah qiimo jaban, fududaynta wax soo saarka, shaqo la isku halleyn karo, iyo shuruudaha rakibida fudud.O-rings waxaa la kulma cadaadis tobanaan megapascals (kilo-pounds).O-rings waxaa loo isticmaali karaa codsiyada taagan iyo sidoo kale codsiyada fir-fircoon ee uu jiro dhaqdhaqaaq qaraabo ah oo ka dhexeeya qaybaha, sida shafts ee bambooyin wareeg ah iyo pistons ee dhululubada Haydarooliga.
O-ring-ku wuxuu ku habboon yahay in lagu rakibo qalab farsamo oo kala duwan, oo hoos yimaada heerkulka la cayimay, cadaadiska, iyo dareeraha kala duwan ee warbaahinta gaaska, waxay ka ciyaari kartaa door xirmo ah oo taagan ama dhaqdhaqaaqa dhaqdhaqaaqa.Noocyo kala duwan oo shaabadood ah ayaa si weyn loogu isticmaalaa qalabka mashiinka, maraakiibta, baabuurta, qalabka hawada, mishiinada biraha, mishiinada kiimikada, mishiinka dhismaha, mishiinka dhismaha, mishiinka macdanta, mishiinka batroolka, mashiinada caaga ah, mishiinka beeraha, iyo qalab kala duwan iyo mitir.curiye.O-rings waxa inta badan loo isticmaalaa xidhidhaynta joogtada ah iyo xidhidhaynta soo noqnoqda.Marka loo isticmaalo shaabadihii dhaqdhaqaaqa rotary, waxay ku xaddidan tahay shaabadaha wareega ee xawaaraha hooseeya.O-ring ayaa guud ahaan lagu rakibay jeexdin oo leh qayb iskutallaab ah oo leydi ah oo ku taal bannaanka ama wareegga gudaha si uu u ciyaaro door xirid.O-rings ayaa weli door wanaagsan ka ciyaara xiridda iyo nuugista naxdinta ee deegaanka sida caabbinta saliidda, caabbinta aashitada iyo alkali, shiida, iyo nabaad guurka kiimikada.Sidaa darteed, O-rings ayaa ah kuwa ugu badan ee si ballaaran loo isticmaalo hababka gudbinta hawo-mareenka iyo hawada.
Elastomers FKM iyo NBR waxaa doorta inta badan macaamiisha Xingtai xinchi.Intaa waxaa dheer, codsiyada heerkulka dhexdhexaadka ah ee u dhexeeya -15 ° C iyo 110 ° C waxaa u adeega labada isku-dar ah, taas oo ka dhigaysa mid walxeed doorasho aad u wanaagsan isticmaalka guud ee warshadaha.Dhab ahaantii, Labada qalabba aad bay ugu habboon yihiin in loo isticmaalo heerkulka -30 ilaa 125 ° C.FKM waxay faa'iido u leedahay heerkulka hoose iyo heerkulka sare.Caag FKM ah ayaa aad u jilicsan oo jilicsan.Laakiin qiimaha elastomer-ka FKM ayaa kor u kacay laga bilaabo Ogosto ee sanadkan, qiimuhu wuu ka sarreeyaa sidii hore.NBR waxay leedahay faa'iido yar marka la barbardhigo adkeysiga muddada gaaban.NBR oo leh iska caabin gaar ah asiidhyada, alkaliyada la qasi jiray, dareerayaasha haydarooliga, biyaha, dareeraha ethylene glycol iyo alkolada.FKM waxay leedahay iska caabin gaar ah oo uumiga, ozone, set cadaadis, caabbinta kiimikaad balaadhan, hydrocarbons caraf udgoon, hydrocarbons koloriin, dareere haydarooliga aan guban, gabowga, acids xoog leh, dareeraha biriiga, acetone, hydrocarbons halogenated, vacuum iyo inta badan acids.
