Abstract: |
Two kinds of low-temperature fluoroether elastomers with different fluorine mass fractions
were selected to prepare standard O-ring seals(24. 99 mm×3. 53 mm). The physical properties of two O-ring
seals and their resistances to Mobil Oil Ⅱ,Great Wall 4050 and FDS-655-HTS aeroengine lubricating
oils were studied. The results showed that,the properties of the O-ring seals prepared with the fluoroether
elastomer(brand VPL85730) which had a higher fluorine mass fraction had little change in the three kinds of
aeroengine lubricants,while O-ring seals prepared with the fluoroether elastomer(brand PL855) which had
a lower fluorine mass fraction maintained stable property only in Mobil Oil Ⅱ. When the properties of O-ring
seal changed greatly in the aeroengine lubricating oil,a considerable amount of carbon black could separate
from the rubber matrix. |
