Polyurethane sealing ring inoratidzwa nekupfeka kuramba, mafuta, asidhi uye alkali, ozone, kuchembera, kuderera kwekushisa, kubvarura, kukanganisa, etc. Polyurethane sealing ring ine mutoro mukuru unotsigira simba uye inoshandiswa zvakanyanya munzvimbo dzakasiyana-siyana. Pamusoro pezvo, mhete yekuisa chisimbiso inodzivirira mafuta, inodzivirira hydrolysis, isingapfeki, uye ine simba rakawanda, inokodzera midziyo yemafuta ekumanikidza, midziyo yekusimudza, maturusi emuchina wekuforoma, midziyo mikuru yehydraulic, nezvimwe.
Polyurethane chisimbiso mhete: polyurethane ine yakanaka kwazvo mekiniki zvivakwa, uye kupfeka kwayo kuramba uye kusimba kwekumanikidza kwakanyanya kupfuura mamwe marubha. Kuramba kuchembera, ozone kuramba uye kuramba mafuta zvakare zvakanaka, asi zviri nyore kuita hydrolyze pakupisa kwakanyanya. Iyo inowanzo shandiswa kune yakakwirira-inopokana uye inopfeka-inodzivirira seal link, senge hydraulic cylinders. Kazhinji, tembiricha siyana - 45 ~ 90 ℃.
Pamusoro pekusangana nezvinodiwa zvekuisa chisimbiso mhete, polyurethane mhete yekuisa chisimbiso inofanirawo kutarisisa kune anotevera mamiriro:
(1) Yakazara nekusimba uye kusimba;
(2) Yakakodzera mechanical simba, kusanganisira kuwedzera simba, elongation uye kubvarura kuramba.
(3) Kushanda kwakagadzikana, kwakaoma kuzvimba mukati, uye diki inopisa shrinkage effect (Joule effect).
(4) Zviri nyore kugadzirisa uye kuumba, uye inogona kuchengetedza saizi chaiyo.
(5) Haiparadze nzvimbo yekubata uye inosvibisa iyo yepakati.
Ningbo Yokey Automotive Parts Co., Ltd inotarisa pakugadzirisa matambudziko evatengi ezvigadzirwa zverabha uye kugadzira akasiyana maumbirwo emhando zvichienderana neakasiyana mashandisirwo mamiriro.
