System nanoporous media - Non-wetting liquid, as a basis for the development of shock damper

Abstract

In this work the method of system nanoporous medium - non-wetting liquid testing for damping devices presented. The method was tested for four systems nanoporous medium - non-wetting liquid. As a nanoporous medium was used commercial samples produced by Sigma-Aldrich hydrophobic silica Fluka 60 C8, Fluka 100 C8, Fluka 100 C18 and Fluka 90 C18. As a non-wetting liquid was used distilled water. These systems have been investigated in the temperature range 20 ÷ 60° C, the maximum energy of impact was 100 J. According to the method, time, power and energy characteristics of the process of non-wetting liquid intrusion - extrusion was determined. Also presented the dependences of impact processes characteristics on temperature.
