Yakagadzirirwa zvinhu NBR/EPDM/FKM/SIL Rubber O-Ring
Detail
O-ring igasket rine O-section kudzivirira kubuda kwemvura neguruva. Isu tinopa huwandu hwakawanda hwezvigadzirwa zverubha, zvakakodzera kune ese mamiriro ekushandiswa.
O-mhete iO-shaped (circular) gasket ine muchinjiko chikamu chinomisikidzwa mugoro uye yakamisikidzwa zvakanaka kudzivirira kubuda kwemvura dzakasiyana semafuta, mvura, mhepo uye gasi.
Tichishandisa zvigadzirwa zvemarubha zvakakodzerwa nemhando dzakasiyana-siyana, tinopa O-mhete dzinogona kumira kwenguva yakareba yebasa mumamiriro ezvinhu akaoma.
4 mhando dzezvakajairwa O-ring zvinhu
NBR
Nitrile Rubber inogadzirwa necopolymerization yeacrylonitrile uye butadiene. Zvinyorwa zve acrylonitrile zvinobva pa18% kusvika ku50%. Iyo yakakwirira yemukati yeacrylonitrile, zviri nani kuramba mafuta ehydrocarbon mafuta, asi tembiricha yakadzikira yakaipisisa, iyo tembiricha yekushandisa yakawanda ndeye -40 ~ 120 ℃. Butanol imwe yeinonyanya kushandiswa rabha yemafuta zvisimbiso uye O-mhete.
Zvakanakira:
· Kuramba kwakanaka kumafuta, mvura, solvent uye high pressure oil.
· Yakanaka compression deflection, kupfeka kuramba uye kurebesa.
Zvakaipa:
· Haina kukodzera kunyungudutsa polar senge ketoni, ozone, nitro hydrocarbons, MEK uye chloroform. · Inoshandiswa kugadzira tangi yemafuta, tangi yemafuta ekuzora uye zvikamu zverabha, kunyanya kuvhara zvikamu, zvinoshandiswa mupetroleum hydraulic oiri, peturu, mvura, silicon girisi, silicon mafuta, diester lubricating mafuta, ethylene glycol hydraulic oiri uye imwe fluid media. Ndiyo inonyanya kushandiswa uye yakaderera mutengo rubber seal.
FKM
Fluoro Carbon Rubber Chero emhando dzakasiyana zvichienderana nefluorine zvirimo (monomer chimiro) chefluorine mamorekuru. Kudzivirira kwekushisa kwepamusoro kuri nani kupfuura silicone rabha, ine yakanakisa makemikari kuramba, kuramba kune akawanda emafuta uye solvent (kunze kweketone, ester), kuramba kwemamiriro ekunze uye ozone kuramba; Cold resistance haina kunaka, kushandiswa kwese kwekushisa kwe -20 ~ 250 ℃. Special formula inogona kumira yakadzika tembiricha kusvika -40 ℃. Zvakanakira:
· Kupisa kupisa kusvika 250 ℃
· Inodzivirira kumafuta mazhinji uye zvinonyungudutsa, kunyanya ese maasidhi, aliphatic, anonhuwirira uye emhuka nemafuta emiriwo.
Zvakaipa:
· Hazvikurudzirwe kune ketoni, esters yelow molecular weight uye misanganiswa ine nitrate. · Mota, locomotives, injini dzedhiziri uye masisitimu emafuta.
SIL
Silicone Rubber main chain yakagadzirwa nesilicon (-si-O-Si) yakabatanidzwa pamwechete. Yakanakisa kupisa kupisa, kutonhora kuramba, ozone kuramba, mumhepo kuchembera kuramba. Kushanda zvakanaka kwekudzivirira kwemagetsi. Simba rekusimba rerabha rakajairwa harina kunaka uye harina mafuta. Zvakanakira:
· Kusimba simba kusvika ku1500PSI uye kubvarura kuramba kusvika ku88LBS mushure mekugadzirwa.
· Yakanaka elasticity uye yakanaka compression kukanganisa
· Kuramba kwakanaka kune zvakarerekera zvinonyungudutsa
· Yakanakisa kupisa kusagadzikana
· Yakanakisa kutonhora kuramba
· Yakanakisa kuramba kune ozone uye oxide erosion
Yakanakisa magetsi ekudzivirira kuita
· Yakanakisa kupisa kupisa uye kupisa kupisa
Zvakaipa:
· Hazvikurudzirwe kushandiswa mune yakawanda yakanyungudika zvinonyungudutsa, oiri, concentrated acids uye diluted sodium hydroxide. · Zvisimbiso kana zvikamu zverabha zvinoshandiswa muindasitiri yemidziyo yemumba, senge POTS yemagetsi, irons, zvikamu zverabha mumavheni emicrowave.
· Zvisimbiso kana zvikamu zverabha muindasitiri yemagetsi, senge makiyi enharembozha, zvekuvhundutsa muDVD, zvisimbiso mumajoini etambo, nezvimwe.
· Zvisimbiso pamhando dzese dzezvinyorwa zvinosangana nemuviri wemunhu, semabhodhoro emvura, zvitubu zvekunwa, nezvimwe.
Epdm
Ethylene Rubber (PPO) inoumbwa kubva kuEthylene uye propylene mucheni huru uye ine yakanakisa kupisa kupisa, kuchembera kuramba, ozone kuramba uye kugadzikana, asi haigone kuwedzerwa sarufa. Kuti agadzirise dambudziko iri, chikamu chiduku chechikamu chechitatu chine ketani kaviri chinopinzwa muketani huru yeEP, iyo inogona kuumbwa nekuwedzera sarufa kuEPDM. The general tembiricha renji -50 ~ 150 ℃. Yakanakisa kuramba kune polar solvents senge doro, ketone, glycol uye phosphate lipid hydraulic fluid.
Zvakanakira:
· Kuramba kwakanaka kwemamiriro ekunze uye kuramba kwe ozone
· Yakanakisa kudzivirira kwemvura uye kusagadzikana kwemakemikari
· Doro nemaketone zvinogona kushandiswa
· Yakakwira tembiricha yehutsi kuramba, yakanaka kusamira kune gasi
Zvakaipa:
· Hazvikurudzirwe kushandiswa kwechikafu kana kuratidzwa kune anonhuwirira haidrojeni. · Zvisimbiso zvepamusoro tembiricha yemhute yemvura nharaunda.
· Zvisimbiso kana zvikamu zvemidziyo yekugezera.
· Zvikamu zverabha mubhureki (braking) system.
· Zvisimbiso mumaradiyeta (matangi emvura emota).
