Izinto ezenziwe ngokwezifiso i-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%. Ukuphakama kokuqukethwe kwe-acrylonitrile, kuba ngcono ukumelana nowoyela kaphethiloli we-hydrocarbon, kodwa ukusebenza okuphansi kwezinga lokushisa kubi kakhulu, izinga lokushisa elivamile elisetshenziswayo lingu-40~120 ℃. I-Butanol ingenye yenjoloba evame ukusetshenziswa kakhulu kuma-seals kawoyela nama-O-rings.

Izinzuzo:

· Ukumelana kahle nowoyela, amanzi, i-solvent kanye nowoyela onengcindezi ephezulu.

· Ukuchezuka okuhle kokucindezelwa, ukumelana nokugqoka kanye nokwelula.

Ububi:

· Ayizifanele izincibilikisi ze-polar njenge-ketone, i-ozone, ama-nitro hydrocarbons, i-MEK ne-chloroform. · Isetshenziselwa ukwenza ithangi likaphethiloli, ithangi likawoyela wokugcoba kanye nezingxenye zenjoloba, ikakhulukazi izingxenye zokuvala, ezisetshenziswa kuwoyela we-petroleum hydraulic, uphethiloli, amanzi, i-silicon grease, uwoyela we-silicon, uwoyela wokuthambisa i-diester, uwoyela we-ethylene glycol hydraulic nezinye izinto eziwuketshezi. Iwuphawu lwerabha olusetshenziswa kakhulu futhi olubiza kancane.

I-FKM

Irabha Yekhabhoni ye-Fluoro Noma yiziphi izinhlobo ezihlukahlukene kuye ngokuqukethwe kwe-fluorine (isakhiwo se-monomer) sama-molecule e-fluorine. Ukumelana nokushisa okuphezulu kungcono kunerabha ye-silicone, inokumelana okuhle kakhulu kwamakhemikhali, ukumelana neningi lamafutha kanye ne-solvent (ngaphandle kwe-ketone, i-ester), ukumelana nesimo sezulu kanye nokumelana ne-ozone; Ukumelana okubandayo akubi, ukusetshenziswa okujwayelekile kwezinga lokushisa elingu-20 ~ 250 ℃. Ifomula ekhethekile ingamelana nezinga lokushisa eliphansi elifinyelela ku -40 ℃. Izinzuzo:

· Ukumelana nokushisa ku-250 ℃

· Imelana namafutha amaningi nezincibilikisi, ikakhulukazi wonke ama-acids, i-aliphatic, iphunga elimnandi kanye namafutha ezilwane nemifino.

Ububi:

· Akunconyelwe ama-ketones, ama-ester anesisindo esiphansi samangqamuzana nezingxube eziqukethe i-nitrate. · Izimoto, izitimela, izinjini zikadizili namasistimu kaphethiloli.

SIL

I-Silicone Rubber main chain yenziwe nge-silicon (-si-O-Si) ehlanganiswe ndawonye. Ukumelana nokushisa okuhle kakhulu, ukumelana nokubanda, ukumelana ne-ozone, ukumelana nokuguga komkhathi. Ukusebenza kahle kokufakwa kukagesi. Amandla aqinile enjoloba evamile ampofu futhi awanakho ukumelana nowoyela. Izinzuzo:

Amandla aqinile afika ku-1500PSI kanye nokumelana nezinyembezi kufika ku-88LBS ngemva kokwakhiwa

· Ukunwebeka okuhle nokuhlanekezela okuhle kokucindezela

· Ukumelana kahle nezincibilikisi ezingathathi hlangothi

· Ukumelana nokushisa okuhle kakhulu

· Excellent ukumelana amakhaza

· Ukumelana okuhle kakhulu nokuguguleka kwe-ozone ne-oxide

Ukusebenza okuhle kakhulu kokufakwa kukagesi

· Ukushisa okuhle kakhulu nokukhipha ukushisa

Ububi:

· Akunconyelwe ukusetshenziswa kuzincibilikisi eziningi ezigxilile, uwoyela, ama-acid agxilile kanye ne-sodium hydroxide ehlanjululwe. · Izivalo noma izingxenye zenjoloba ezisetshenziswa embonini yezinto zikagesi zasendlini, njengama-POTS kagesi, ama-ayina, izingxenye zenjoloba kumahhavini ama-microwave.

· Izigxivizo noma izingxenye zenjoloba embonini ye-elekthronikhi, njengokhiye bezingcingo eziphathwayo, izinto zokudonsa ukushaqeka ku-DVD, ama-seal kumajoyinti ekhebula, njll.

· Ama-seal kuzo zonke izinhlobo zezinto ezithinta umzimba womuntu, njengamabhodlela amanzi, imithombo yokuphuza, njll.

Epdm

I-Ethylene Rubber (PPO) yenziwe nge-copolymerized isuka ku-Ethylene kanye ne-propylene ibe yiketango elikhulu futhi inokumelana nokushisa okuhle kakhulu, ukumelana nokuguga, ukumelana ne-ozone nokuzinza, kodwa ayinakwengezwa isibabule. Ukuze kuxazululwe le nkinga, inani elincane lengxenye yesithathu eneketanga eliphindwe kabili lingeniswa ochungechungeni oluyinhloko lwe-EP, olungakhiwa ngokungeza isulfure ku-EPDM. Izinga lokushisa elijwayelekile lingu -50 ~ 150 ℃. Ukumelana okuhle kakhulu nezincibilikisi ze-polar ezifana notshwala, i-ketone, i-glycol ne-phosphate lipid hydraulic fluids.

Izinzuzo:

· Ukumelana nesimo sezulu esihle nokumelana ne-ozone

· Ukumelana kwamanzi okuhle kakhulu nokumelana namakhemikhali

· Utshwala nama-ketones kungasetshenziswa

· Ukumelana nezinga lokushisa eliphezulu kwesitimu, ukungangeni kahle kwegesi

Ububi:

· Akunconyelwe ukusetshenziswa kokudla noma ukuchayeka ku-hydrogen enamakha. · Seals for izinga lokushisa eliphezulu amanzi umhwamuko imvelo.

· Izivalo noma izingxenye zemishini yokugezela.

· Izingxenye zenjoloba ohlelweni lokubhuleka (ukubhuleka).

· Ama-seal kuma-radiator (mathange amanzi emoto).
