Alaab la habeeyey oo NBR/EPDM/FKM/SIL ah oo caag ah O-Ring

NBR

Nitrile Rubber waxaa lagu diyaariyaa isku-darka acrylonitrile iyo butadiene. Waxyaabaha ku jira acrylonitrile waxay u dhexeeyaan 18% ilaa 50%. Inta ay ka badan tahay acrylonitrile, waxay ka sii fiican tahay iska caabbinta saliidda shidaalka haydaro-kaarboon, laakiin waxqabadka heerkulka hooseeya ayaa ka sii daran, heerkulka guud ee isticmaalka waa -40~120 ℃. Butanol waa mid ka mid ah caagga ugu badan ee loo isticmaalo shaabadaynta saliidda iyo giraanta O.

Faa'iidooyinka:

· Iska caabin wanaagsan oo ku timaada saliidda, biyaha, dareeraha iyo saliidda cadaadiska sare leh.

· Si fiican u leexashada cadaadiska, iska caabinta xirashada iyo dheereynta.

Qasaarooyinka:

· Kuma habboona dareerayaasha polar-ka sida ketones, ozone, nitro hydrocarbons, MEK iyo chloroform. · Waxaa loo isticmaalaa sameynta taangiga shidaalka, saliidaynta taangiga saliidda iyo qaybaha caagga ah, gaar ahaan qaybaha shaabadaynta, oo loo isticmaalo saliidda haydarooliga batroolka, gaaska, biyaha, dufanka silikoon, saliidda silikoon, saliidda saliidaynta diester, saliidda haydarooliga ee ethylene glycol iyo warbaahinta kale ee dareeraha ah. Waa shaabadda cinjirka ugu isticmaalka badan uguna jaban.

FKM

Kaarboon Fluoro ah Nooc kasta oo kala duwan iyadoo ku xiran maaddada fluorine (qaab-dhismeedka monomer) ee molecules-ka fluorine. Iska caabbinta heerkulka sare waxay ka fiican tahay caagga silikoon, waxay leedahay iska caabbinta kiimikada oo aad u fiican, iska caabbinta inta badan saliidda iyo dareeraha (marka laga reebo ketone, ester), iska caabbinta cimilada iyo iska caabbinta ozone; Iska caabbinta qabowgu waa mid liidata, isticmaalka guud ee heerkulka waa -20~250 ℃. Qaacido gaar ah ayaa u adkaysan karta heerkulka hooseeya ilaa -40 ℃. Faa'iidooyinka:

· Iska caabbinta kulaylka ilaa 250 ℃

· Waxay u adkaysataa inta badan saliidaha iyo dareerayaasha, gaar ahaan dhammaan asiidhyada, saliidaha aliphatic, aromatic iyo kuwa xayawaanka iyo khudaarta.

Qasaarooyinka:

· Laguma talinayo ketones, esters-ka miisaanka molecular-ka hooseeya iyo isku-darka ay ku jiraan nitrate. · Gawaarida, tareenada dhulka hoostiisa mara, matoorada naaftada iyo nidaamyada shidaalka.

SIL

Silsiladda ugu weyn ee caagga silikoon waxa laga sameeyay silicon (-si-O-Si) oo isku xidhan. Iska caabbinta kulaylka oo aad u fiican, iska caabbinta qabowga, iska caabbinta ozone-ka, iska caabbinta gabowga jawiga. Waxqabadka dahaarka korontada oo wanaagsan. Xoogga jiidista ee caagga caadiga ah waa mid liita mana laha iska caabbinta saliidda. Faa'iidooyinka:

· Xoogga jiidista ilaa 1500PSI iyo iska caabbinta jeexjeexa ilaa 88LBS ka dib qaacidada

· Balac wanaagsan iyo qallooc cadaadis wanaagsan

· Iska caabin wanaagsan oo loogu talagalay dareerayaasha dhexdhexaadka ah

· Iska caabin kulayl oo aad u fiican

· Iska caabin qabow oo aad u fiican

· Iska caabin aad u fiican oo ku wajahan nabaad-guurka ozone iyo oksaydhka

Waxqabadka dahaarka korontada ee aadka u fiican

· Dahaarka kulaylka iyo kala-baxa kulaylka oo aad u fiican

Qasaarooyinka:

· Laguma talinayo in loo isticmaalo inta badan dareerayaasha xoogga badan, saliidaha, asiidhyada xoogga badan iyo sodium hydroxide-ka la qasi jiray. · Shaabado ama qaybo caag ah oo loo isticmaalo warshadaha qalabka guryaha, sida WEBSYADA korantada, birta, qaybaha caagga ah ee foornooyinka microwave-ka.

· Shaabado ama qaybo caag ah oo warshadaha elektaroonigga ah, sida furayaasha taleefanka gacanta, nuugayaasha shoogga ee DVD-ga, shaabado ku jira godadka fiilooyinka, iwm.

· Waxay shaabadaysaa dhammaan noocyada walxaha taabanaya jidhka bini'aadamka, sida dhalooyinka biyaha, ilo biyoodka la cabbo, iwm.

Epdm

Ethylene Rubber (PPO) waxaa laga soo saaraa Ethylene iyo propylene silsiladda ugu weyn waxayna leedahay iska caabin kulayl oo aad u fiican, iska caabin gabowga, iska caabinta ozone iyo xasilloonida, laakiin laguma dari karo sulfur. Si loo xalliyo dhibaatadan, xaddi yar oo ka mid ah qaybta saddexaad oo leh silsilad labanlaab ah ayaa lagu soo bandhigayaa silsiladda ugu weyn ee EP, taas oo lagu samayn karo iyadoo lagu darayo sulfur EPDM. Heerkulka guud waa -50~150 ℃. Iska caabin aad u fiican oo loogu talagalay dareerayaasha polar sida khamriga, ketone, glycol iyo dareeraha lipid lipid phosphate.

Faa'iidooyinka:

· Iska caabbinta cimilada wanaagsan iyo iska caabbinta ozone-ka

· Iska caabin biyo oo aad u fiican iyo iska caabin kiimiko

· Khamriga iyo ketones-ka waa la isticmaali karaa

· Heerkulka sare u adkaysta uumiga, u adkaysta gaaska oo si fiican u adkaysta

Qasaarooyinka:

· Laguma talinayo in la isticmaalo cuntada ama la kulmo haydarojiin udgoon. · Waxay ku dahaadhaa jawi uumi biyood oo heerkul sare leh.

· Shaabado ama qaybo loogu talagalay qalabka musqusha.

· Qaybaha cinjirka ah ee nidaamka bareegga (bareegga).
