Izinto ezenziwe ngokwezifiso ze-NBR/EPDM/FKM/SIL Rubber O-Ring

I-NBR

I-Nitrile Rubber ilungiswa nge-copolymerization ye-acrylonitrile ne-butadiene. Okuqukethwe kwe-acrylonitrile kusuka ku-18% kuya ku-50%. Uma okuqukethwe kwe-acrylonitrile kuphakeme, kulapho ukumelana nophethiloli we-hydrocarbon kungcono khona, kodwa ukusebenza kwezinga lokushisa eliphansi kubi kakhulu, izinga lokushisa elijwayelekile lokusetshenziswa lingu-40~120 ℃. I-Butanol ingenye yerabha esetshenziswa kakhulu ezivalweni zikawoyela kanye nama-O-rings.

Izinzuzo:

· Ukumelana okuhle namafutha, amanzi, isinyibilikisi kanye namafutha anomfutho ophezulu.

· Ukuphambuka okuhle kokucindezelwa, ukumelana nokuguguleka kanye nokwelulwa.

Okubi:

· Ayifaneleki izinyibilikisi ze-polar ezifana nama-ketone, i-ozone, ama-nitro hydrocarbon, i-MEK kanye ne-chloroform. · Isetshenziselwa ukwenza ithangi likaphethiloli, ithangi likawoyela lokuthambisa kanye nezingxenye zerabha, ikakhulukazi izingxenye zokuvala, isetshenziswa ku-petroleum hydraulic oil, uphethiloli, amanzi, i-silicon grease, i-silicon oil, i-diester lubricating oil, i-ethylene glycol hydraulic oil kanye nezinye izinto eziwuketshezi. Yisivikelo serabha esisetshenziswa kakhulu futhi esibiza kancane.

I-FKM

Irabha ye-Fluoro Carbon Noma yiluphi uhlobo oluhlukahlukene kuye ngokuthi okuqukethwe yi-fluorine (isakhiwo se-monomer) sama-molecule e-fluorine kungakanani. Ukumelana nokushisa okuphezulu kungcono kunerabha ye-silicone, kunokumelana okuhle kwamakhemikhali, ukumelana namafutha amaningi kanye nesinyibilikisi (ngaphandle kwe-ketone, i-ester), ukumelana nesimo sezulu kanye nokumelana ne-ozone; Ukumelana nokubanda akukuhle, ukusetshenziswa okuvamile kwezinga lokushisa elingu--20~250 ℃. Ifomula ekhethekile ingamelana nokushisa okuphansi kufika ku--40 ℃. Izinzuzo:

· Ukumelana nokushisa ku-250 ℃

· Ayimelani namafutha amaningi kanye nezinyibilikisi, ikakhulukazi wonke ama-asidi, amafutha e-aliphatic, aromatic kanye namafutha ezilwane nawemifino

Okubi:

· Akukhuthazwa ngama-ketone, ama-ester anesisindo esiphansi sama-molecule kanye nezingxube eziqukethe i-nitrate. · Izimoto, izitimela, izinjini zedizili kanye nezinhlelo zikaphethiloli.

I-SIL

Iketanga elikhulu lerabha le-Silicone lenziwe nge-silicon (-si-O-Si) ehlanganiswe ndawonye. Ukumelana nokushisa okuhle kakhulu, ukumelana nokubanda, ukumelana ne-ozone, ukumelana nokuguga emoyeni. Ukusebenza kahle kokuvikela ugesi. Amandla okuthamba erabha evamile aphansi futhi awanamandla okumelana nowoyela. Izinzuzo:

· Amandla okunamathela afinyelela ku-1500PSI kanye nokumelana nokudabuka okufika ku-88LBS ngemva kokwenziwa

· Ukuqina okuhle kanye nokuphambuka okuhle kokucindezelwa

· Ukumelana okuhle nezinyibilikisi ezingathathi hlangothi

· Ukumelana nokushisa okuhle kakhulu

· Ukumelana nokubanda okuhle kakhulu

· Ukumelana okuhle kakhulu nokuguguleka kwe-ozone ne-oxide

Ukusebenza kahle kakhulu kokushisa kukagesi

· Ukuvikela ukushisa okuhle kakhulu kanye nokushabalalisa ukushisa

Okubi:

· Akukhuthazwa ukusetshenziswa ezincibilikisini eziningi ezihlanganisiwe, amafutha, ama-asidi ahlanganisiwe kanye ne-sodium hydroxide exutshiwe. · Izivalo noma izingxenye zerabha ezisetshenziswa embonini yezinto zasekhaya, njengezimbiza zikagesi, ama-ayina, izingxenye zerabha kuma-oven e-microwave.

· Izivalo noma izingxenye zerabha embonini ye-elekthronikhi, njengezikhiye zefoni ephathekayo, izimbozi zokushaqeka kuma-DVD, izivalo ezisemajoyintini ekhebula, njll.

· Izivalo kuzo zonke izinhlobo zezinto ezithinta umzimba womuntu, njengezibhodlela zamanzi, imithombo yokuphuza, njll.

I-Epdm

I-Ethylene Rubber (PPO) i-copolymerized kusuka ku-Ethylene kanye ne-propylene ibe yi-main chain futhi inokumelana okuhle kakhulu nokushisa, ukumelana nokuguga, ukumelana ne-ozone kanye nokuqina, kodwa ayikwazi ukwengezwa isibabule. Ukuxazulula le nkinga, inani elincane lengxenye yesithathu ene-double chain lifakwa ku-main chain ye-EP, engakhiwa ngokungeza isibabule ku-EPDM. Ububanzi bokushisa obujwayelekile bungu--50~150 ℃. Ukumelana okuhle kakhulu nezinyibilikisi ze-polar ezifana notshwala, i-ketone, i-glycol kanye ne-phosphate lipid hydraulic fluids.

Izinzuzo:

· Ukumelana nesimo sezulu okuhle kanye nokumelana ne-ozone

· Ukumelana namanzi okuhle kakhulu kanye nokumelana namakhemikhali

· Ama-alcohol nama-ketone angasetshenziswa

· Ukumelana nomusi oshisayo kakhulu, ukungangenwa kahle yigesi

Okubi:

· Akukhuthazwa ukusetshenziswa kokudla noma ukuchayeka ku-hydrogen enuka kamnandi. · Kuvikela indawo enomswakama wamanzi enokushisa okuphezulu.

· Izivalo noma izingxenye zemishini yokugezela.

· Izingxenye zerabha ohlelweni lokubhuleka (ukubhuleka).

· Izivalo kuma-radiator (amathangi amanzi emoto).
