Edge Rubber Grommet

Edge Rubber Grommet, oo ah galka siliga cidhifka ah, waa nooc ka mid ah badeecooyinka caagga ah ee loo isticmaalo si looga ilaaliyo cidhifka saamaynta dibadda. Waxaa inta badan loo isticmaalaa in lagu go'doomiyo walxaha geesaha, iyada oo laga ilaalinayo dareeraha kala duwan, boodhka, wasakhda, iwm, isla mar ahaantaana, waxay sidoo kale ka ilaalin kartaa walxaha waxyeellada jireed, isku-dhafka, gariirka, iwm. Tusaale ahaan, warshadaha sida baabuurta, qalabka korontada, iyo alaabta guriga, waxaa loo isticmaali karaa in lagu ilaaliyo fiilooyinka, fiilooyinka ama tuubooyinka si looga hortago in la gooyo ama la gashado qalabka birta ah marka la gooyo ama la gashado qalabka birta ah ee la gooyo ama la gashado. guuldarrooyinka ay sababto burburka fiilada.

Astaamaha caagga ah ee NBR:
Rabadhka Nitrile (NBR, Buna-N) waxa uu bixiyaa iska caabin heersare ah oo ku wajahan saliidaha batroolka iyo sidoo kale macdanta iyo saliidda khudradda. Rabadhka Nitrile waxa kale oo uu bixiyaa iska caabin adag oo kulaylka gabowga - inta badan faa'iido muhim ah oo ka sareysa caagga dabiiciga ah.
Rabadhka Nitrile wuxuu si fiican ugu shaqeeyaa kaarburetarka iyo diaphragms-ka bamka shidaalka, tuubooyinka diyaaradda, shaabadihii iyo gaaskiityada iyo sidoo kale saliidda-tubboyinka safan. Kala duwanaanshaheeda awgeed, nitrile waxaa loo isticmaalaa codsiyada ku lug leh saliida iyo caabbinta shidaalka, laakiin codsiyada u baahan caabbinta kulaylka, xoqitaanka, biyaha, iyo gaaska.

Tilmaamaha Caagga FKM:
Vi{0}ton waxaa iska leh kooxda Fluoroelastomers (FKM/FPM) ee xeryahooda caagga ah. Waxaa jira darajooyin badan iyo kala duwanaansho qallafsanaan si loo xalliyo codsiyada badankooda leh qaabab kala duwan si loo buuxiyo shuruudaha gaarka ah ee heerkulka iyo caabbinta kiimikada. Isticmaalka caadiga ah waxaa ka mid ah: caabbinta kulaylka heer sare ah, sifooyin farsamo oo wanaagsan, adkaysiga u adkaysiga wanaagsan, caabbinta saliidaha iyo shidaalka ballaaran, caabbinta dareeraha; gaar ahaan dhammaan aliphatic, ur iyo halogenated hydrocarbons iyo acids.

Astaamaha caagga ah ee EPDM:
Rabadhka EPDM waa caag cufnaan sare leh oo inta badan loo isticmaalo codsiyada dibadda. Waxay leedahay sifooyin firfircoon iyo farsamo oo u dhexeeya caag dabiici ah iyo caag synthetic.
Ha isticmaalin EPDM haddii xiriir joogto ah oo batroolka ku salaysan loo baahan yahay.
Laguma talin in loo isticmaalo codsiyada cuntada ama kuwa udub dhexaadka u ah hydrocarbons.

Astaamaha caagga ah ee HNBR:
Hydrogenated Nitrile Butadiene Rubber (HNBR), oo sidoo kale loo yaqaan Highly SaturatedNitrile (HSN), waa nooc gaar ah oo caag nitrile ah (NBR) kaas oo la hydrogenated si loo kordhiyo dheehnaanta qaybta butadiene ee laf dhabarta kaarboonka. Hagaajinta soo socota ee agabka maaddooyinka, ee ka sarreeya kan caagga nitrile (NBR), waxaa ka mid ah xasilloonida kulaylka oo weyn, caabbinta kiimikaad oo ballaadhan, iyo xoog xajin oo weyn.
HNBR waxa ay ASTM u kala saartay DH{0}}nooca polymer. Kala soocidaani waxay muujineysaa heerkulka adeega 150ºC iyo sidoo kale in ka yar 30% bararka IRM 903. HNBR waxaa loo qaabayn karaa si loo daboolo heerkulka codsiga ee u dhexeeya -50 digrii iyo 165ºC.

Astaamaha caagga ah ee SBR:
1.Waxyaabaha ugu muhiimsan: Styrene{1}}rubber butadiene (SBR), caag guud -ujeedka caag synthetic ah, oo laga soo saaray kobolymer of styrene iyo butadiene. Marka laga tago dhammaan caagadaha synthetic ee isticmaalka, SBR waxaa loo isticmaalaa tiro aad u badan baabuurta iyo taayirada xamuulka, guud ahaan sida naaxinta{4}} beddelka caagga dabiiciga ah (laga soo saaro polyisoprene).
2.Available Place: Waxaa si weyn loogu isticmaalaa baabuurta, qalabka korontada, dhismaha go'doomin gariirka iyo warshadaha kale. Tusaale ahaan, afuufiyaha hawada, bamka biyaha, qalabka, cabbirka maraakiibta iyo wixii la mid ah.
Waxqabadka 3.Main: SBR waxay leedahay sifooyin kiimiko iyo jireed oo la mid ah caag dabiici ah, oo leh caabbinta caabbinta guud ahaan ka sii wanaagsan, xoog aad u fiican, caabbinta nasashada wanaagsan iyo diiqada iyo kharash yar, iwm. Laguma talin in loo isticmaalo SBR codsiyada ku lug leh ozone, acids xooggan, saliidaha, dufanka, dufanka iyo inta badan hydrocarbons.

Tilmaamaha Rubber Neoprene:
Neoprene Rubber, oo sidoo kale loo yaqaan neoprene polychloroprene, waa caag synthetic ah oo aad isku dhafan oo leh in ka badan 75 sano oo waxqabad la xaqiijiyay.
Dunida baabuurta, neoprene waxa loo isticmaalaa qaar badan oo ka hooseeya --koodhka iyo qaybaha jidhka ee u baahan qiimo macquul ah, dhexda{2}} polymer wax qabad leh dhammaan- ku wareegsan dheelitirnaanta sifooyinka waxqabadka.

Tilmaamaha Caagga Dabiiciga ah:
Caag dabiici ah ayaa asal ahaan ka soo jeeda cinjirka laga helay dheecaanka geedaha caagga ah. Qaabka la safeeyey ee caagga dabiiciga ah ayaa sidoo kale loo soo saari karaa si dabiici ah. Caag dabiici ah ayaa ah polymer ku habboon codsiyada injineernimada firfircoon ama taagan.
Digniin: Caag dabiici ah laguma talinayo codsiyada halka qaybta caagga ah ay soo gaadhi doonto ozone, saliidaha, ama dareerayaasha.

PU/Polyurethane Rubber Astaamaha:
Polyurethane waa polymer organic ah. Polyurethane waxaa lagu sameeyay falcelin polyol ah (alkolo leh in ka badan laba kooxood oo hydroxyl falcelin ah halkii molecule) oo leh diisocyanate ama isocyyanate polymeric iyadoo ay joogaan kiciyayaal ku habboon iyo wax lagu daro. Polyurethane waa xarun si weyn loo isticmaalo sababtoo ah xooggeeda sare, jeexjeexa iyo caabbinta xoqidda. Polyurethane sidoo kale waxay bixisaa iska caabin aad u fiican.

Astaamaha:
Saliida Haydarooliga wanaagsan iyo caabbinta gaasta U adkaysata hydrocarbons saafiga ah Caabbinta macdanta iyo saliidaha silikoonka iyo dufanka U adkaysta biyaha, oksijiinta, ozone iyo gabowga Ilmo aad u fiican iyo iska caabbinta abrasion Waxaa laga heli karaa noocyo badan iyo xeryahooda si loo buuxiyo waxqabadka iyo shuruudaha kharashka
