Cov khoom ntawm polyurethane seals

1. sealing kev ua tau zoo
Polyurethane foob muaj qhov zoo ntawm cov plua plav pov thawj, nws tsis yooj yim rau kev cuam tshuam los ntawm cov khoom siv sab nraud, thiab tiv thaiv kev cuam tshuam sab nraud, txawm tias qhov chaw yog nplaum thiab cov khoom txawv teb chaws tuaj yeem raug khawb tawm.
2. Kev sib txhuam ua haujlwm
High hnav tsis kam thiab muaj zog extrusion kuj.Polyurethane foob tuaj yeem txav mus los ntawm qhov nrawm ntawm 0.05m / s yam tsis muaj lubrication lossis hauv qhov chaw siab ntawm 10Mpa.
3. Zoo roj tsis kam
Polyurethane seals yuav tsis raug corroded txawm nyob rau hauv lub ntsej muag ntawm kerosene, roj av thiab lwm yam roj los yog mechanical roj xws li hydraulic roj, cav roj thiab lubricating roj.
4. Lub neej ua haujlwm ntev
Nyob rau hauv tib lub sijhawm, kev pabcuam lub neej ntawm polyurethane seals yog 50 npaug ntau dua li cov khoom siv NBR seals.Polyurethane seals yog qhov zoo tshaj plaws ntawm kev hnav tsis kam, lub zog thiab tsim kua muag.
