Izinto ezenzelwe wena ze-NBR/EPDM/FKM/SIL Rubber O-Ring

I-NBR

Irabha yeNitrile ilungiswa nge-copolymerization ye-acrylonitrile kunye ne-butadiene. Umxholo we-acrylonitrile uphakathi kwe-18% ukuya kwi-50%. Okukhona umxholo we-acrylonitrile uphezulu, kokukhona ukumelana neoyile ye-hydrocarbon fuel kungcono, kodwa ukusebenza kobushushu obuphantsi kubi, uluhlu lobushushu olusetyenziswa ngokubanzi yi--40~120 ℃. I-Butanol yenye yezona rabha zisetyenziswa kakhulu kwizitywini zeoyile kunye nee-O-rings.

Iingenelo:

· Ukumelana kakuhle neoyile, amanzi, isinyibilikisi kunye neoyile yoxinzelelo oluphezulu.

· Ukujika koxinzelelo kulungile, ukumelana nokuguguleka kunye nobude.

Iingxaki:

· Ayifanelekanga kwii-polar solvents ezifana nee-ketones, i-ozone, ii-nitro hydrocarbons, i-MEK kunye ne-chloroform. · Isetyenziselwa ukwenza itanki yepetroli, itanki yeoyile yokuthambisa kunye neendawo zerabha, ingakumbi iindawo zokuvala, isetyenziswa kwi-oyile ye-hydraulic ye-petroleum, ipetroli, amanzi, i-silicon grease, i-silicon oil, i-diester lubricating oil, i-ethylene glycol hydraulic oil kunye nezinye izinto ezisetyenziswayo. Yeyona seal yerabha isetyenziswa kakhulu kwaye ixabisa kancinci.

FKM

Irabha yeFluoro Carbon Naluphi na uhlobo oluhlukeneyo oluxhomekeke kumxholo wefluorine (isakhiwo se-monomer) seemolekyuli zefluorine. Ukumelana nobushushu obuphezulu kungcono kunerabha yesilicone, inokumelana okuhle kweekhemikhali, ukumelana neoyile eninzi kunye nesinyibilikisi (ngaphandle kwe-ketone, i-ester), ukumelana nemozulu kunye nokumelana ne-ozone; Ukumelana nokubanda akukuhle, ukusetyenziswa ngokubanzi kobushushu yi--20~250 ℃. Ifomula ekhethekileyo inokumelana nobushushu obuphantsi ukuya kuthi ga kwi--40 ℃. Iingenelo:

· Ukumelana nobushushu ukuya kuma-250 ℃

· Ayichasani neeoyile ezininzi kunye nezinyibilikisi, ingakumbi zonke ii-asidi, iioyile ze-aliphatic, iioyile ze-aromatic kunye neeoyile zezilwanyana kunye nemifuno

Iingxaki:

· Akukhuthazwa kwii-ketones, ii-esters ezinobunzima obuphantsi beemolekyuli kunye nemixube equlethe i-nitrate. · Iimoto, iilocomotives, iinjini zedizili kunye neenkqubo zepetroli.

I-SIL

Itsheyini ephambili yerabha yeSilicone yenziwe ngesilicon (-si-O-Si) edityaniswe kunye. Ukumelana nobushushu okugqwesileyo, ukumelana nokubanda, ukumelana ne-ozone, ukumelana nokwaluphala emoyeni. Ukusebenza kakuhle kokugquma umbane. Amandla okutsalwa kwerabha eqhelekileyo aphantsi kwaye ayinayo ukumelana neoyile. Iingenelo:

· Amandla okutsalwa afikelela kwi-1500PSI kunye nokumelana nokukrazuka ukuya kuthi ga kwi-88LBS emva kokwenziwa

· Ukuqina okuhle kunye nokuphazamiseka okuhle kokucinezelwa

· Ukumelana kakuhle nezinyibilikisi ezingathathi cala

· Ukumelana nobushushu okugqwesileyo

· Ukumelana nokubanda okugqwesileyo

· Ukumelana okugqwesileyo nokukhukuliseka kwe-ozone kunye ne-oxide

Ukusebenza kakuhle kokukhusela umbane

· Ubushushu obugqwesileyo kunye nokususa ubushushu

Iingxaki:

· Akukhuthazwa ukuba kusetyenziswe uninzi lwezinyibilikisi ezixineneyo, iioyile, iiasidi ezixineneyo kunye ne-sodium hydroxide exutyiweyo. · Izitywino okanye iindawo zerabha ezisetyenziswa kushishino lwezixhobo zasekhaya, ezifana neePOTS zombane, ii-ayini, iindawo zerabha kwii-oven ze-microwave.

· Izitywino okanye iindawo zerabha kwishishini le-elektroniki, ezifana nezitshixo zefowuni ephathwayo, izithinteli zoxinzelelo kwiDVD, izitywino ezikwiintambo, njl.njl.

· Izitywino kuzo zonke iintlobo zezinto ezidibana nomzimba womntu, ezinje ngeebhotile zamanzi, imithombo yokusela, njl.njl.

I-Epdm

I-Ethylene Rubber (PPO) yenziwe i-copolymerized ukusuka kwi-Ethylene kunye ne-propylene ibe yi-main chain kwaye inokumelana okuhle kakhulu nobushushu, ukumelana nokwaluphala, ukumelana ne-ozone kunye nozinzo, kodwa ayinakongezwa i-sulfur. Ukusombulula le ngxaki, inani elincinci lenxalenye yesithathu ene-double chain lifakwa kwi-main chain ye-EP, enokwenziwa ngokongeza i-sulfur kwi-EPDM. Uluhlu lobushushu oluqhelekileyo yi--50~150 ℃. Ukumelana okuhle kakhulu kwi-polar solvents ezifana notywala, i-ketone, i-glycol kunye ne-phosphate lipid hydraulic fluids.

Iingenelo:

· Ukumelana kakuhle nemozulu kunye nokumelana ne-ozone

· Ukumelana kakuhle kwamanzi kunye nokumelana neekhemikhali

· Iialcohol kunye neeketones zingasetyenziswa

· Ukumelana nomphunga kubushushu obuphezulu, ukungangenwa kakuhle yigesi

Iingxaki:

· Akukhuthazwa ukuba kusetyenziswe ukutya okanye kusetyenziswe i-hydrogen enuka kamnandi. · Ivala indawo enobushushu obuphezulu yomphunga wamanzi.

· Izitywino okanye iinxalenye zezixhobo zokuhlambela.

· Izixhobo zerabha kwinkqubo yokuqhobosha (ukuqhobosha).

· Izivali kwiiradiator (iitanki zamanzi zemoto).
