Waxyaabaha NBR/EPDM/FKM/SIL Rubber O-Ring
Faahfaahin
O-ring waa gaas leh qaybta O si looga hortago daadinta dareeraha iyo boodhka. Waxaan bixinaa noocyo kala duwan oo qalab caag ah, oo ku habboon dhammaan shuruudaha isticmaalka.
O-ring waa gaas O-qaabeeya (wareeg ah) oo leh qayb iskutallaab ah oo ku go'an jeexdin si habboonna loo miiray si looga hortago daadinta dareerayaasha kala duwan sida saliidda, biyaha, hawada iyo gaasta.
Isticmaalka alaabooyinka caaga ah ee synthetic ee ku habboon codsiyada kala duwan, waxaan ku siinnaa O-rings kuwaas oo u adkeysan kara adeegga muddada dheer ee xaaladaha adag.
4 nooc oo ah qalabka O-ring ee caadiga ah
NBR
Rubber Nitrile waxaa lagu diyaariyaa copolymerization of acrylonitrile iyo butadiene. Waxa ku jira acrylonitrile waxay u dhaxaysaa 18% ilaa 50%. Maaddada sare ee acrylonitrile, way ka sii fiicnaanaysaa caabbinta saliidda shidaalka hydrocarbon, laakiin waxqabadka heerkulka hooseeya ayaa ka sii daraya, heerkulka isticmaalka guud waa -40 ~ 120 ℃. Butanol waa mid ka mid ah caagagga inta badan loo isticmaalo xirmooyinka saliidda iyo O-rings.
Faa'iidooyinka

· Jeexdin wanaagsan, xidhid iska caabin iyo dherer.
Khasaaraha:
Aan ku habboonayn dareerayaasha polar sida ketones, ozone, hydrocarbons nitro, MEK iyo chloroform. Waxaa loo isticmaalaa samaynta haanta shidaalka, saliida saliidda lagu subiyo iyo qaybaha caagga ah, gaar ahaan qaybaha xidhitaanka, loo isticmaalo saliidda hydraulic petroleum, shidaalka, biyaha, silikoon dufan, Saliid Silicon, saliid saliid saytuun ah, saliidda ethylene glycol hydraulic oil iyo dareere kale. Waa shaabadda caagga ah ee ugu isticmaalka badan uguna jaban.
FKM
Caag Kaarboon Kaarboon ah Mid kasta oo ka mid ah noocyada kala duwan ee ku xiran waxa ku jira fluorine (qaabka monomer) ee molecules fluorine. Cadaadiska heerkulka sare wuxuu ka fiican yahay caag silikoon ah, wuxuu leeyahay iska caabin kiimiko oo heer sare ah, caabbinta inta badan saliidda iyo dareeraha (marka laga reebo ketone, ester), caabbinta cimilada iyo iska caabinta ozone; Iska caabbinta qabowgu waa mid liidata, isticmaalka guud ee heerkulka heerkulka -20 ~ 250 ℃. Caanaha gaarka ah waxay u adkeysan kartaa heerkulka hooseeya ilaa -40 ℃. Faa'iidooyinka
U adkaysiga kulaylka ilaa 250 ℃
· U adkaysta badi saliidaha iyo dareerayaasha, gaar ahaan dhammaan asiidhyada, alifleyda, udugga iyo xayawaanka iyo saliidaha khudradda
Khasaaraha:
Laguma talinayo ketones, esters miisaankoodu hooseeyo iyo isku dhafka ay ku jirto nitrate. Baabuurta, matoorrada naaftada iyo hababka shidaalka.
SIL
Silikoon Rubber-ka ugu weyn wuxuu ka samaysan yahay silikoon (-si-O-Si) oo isku xidhan. Iska caabin kulayl aad u fiican, iska caabin qabow, iska caabin ozone, caabbinta gabowga atmospheric. Waxqabad koronto oo wanaagsan. Xoogga caagga caadiga ah waa liidata mana laha caabbinta saliidda. Faa'iidooyinka
· Xoog xajin ilaa 1500PSI iyo iska caabin jeexjeex ah ilaa 88LBS samaynta ka dib
Laastiig wanaagsan iyo qallooc wanaagsan oo cadaadis ah
Iska caabbinta wanaagsan ee dareerayaasha dhexdhexaadka ah
· Iska caabin kulayl oo aad u wanaagsan
· Iska caabin qabow oo heer sare ah
Iska caabin heer sare ah oo u adkaysta ozone iyo oxide nabaad guurka
Waxqabad koronto oo heer sare ah
· Xakamaynta kulaylka aad u fiican iyo kulaylka kala daadinta
Khasaaraha:
Laguma talin in la isticmaalo inta badan dareerayaasha uruursan, saliidaha, asiidhyada uruursan iyo sodium hydroxide la qaso. • Shaabadadaha ama qaybaha caagga ah ee loo isticmaalo warshadaha qalabka guriga, sida weelasha korontada, birta, qaybaha caagga ah ee foornooyinka microwave-ka.
• Shaabadadaha ama qaybaha caagga ah ee warshadaha elektaroonigga ah, sida furayaasha taleefanka gacanta, kuwa shoogga ee DVD-ga ku jira, xirmooyinka fiilooyinka, iwm.
· Shaabad lagu xidho dhammaan noocyada kala duwan ee walxaha la xidhiidha jidhka bini'aadamka, sida caagagga biyaha, meelaha laga cabbo, iwm.
Epdm
Ethylene Rubber (PPO) waxa ay ka samaysan tahay Ethylene iyo propylene oo laga dhigay silsiladda weyn waxana ay leedahay iska caabin kulayl aad u fiican, caabbinta gabowga, iska caabinta ozone iyo xasilloonida, laakiin laguma dari karo baaruud. Si loo xalliyo dhibaatadan, qadar yar oo ka mid ah qaybta saddexaad oo leh silsilad labajibbaaran ayaa la geliyaa silsiladda ugu weyn ee EP, taas oo lagu samayn karo iyada oo lagu daro baaruud EPDM. Heerkulka guud waa -50 ~ 150 ℃. Iska caabin heer sare ah oo ka dhan ah dareerayaasha polar sida khamriga, ketone, glycol iyo fosfatetada dareeraha hydraulic lipid.
