Rubber surface fluorination modification testing device

Abstract

The invention discloses a rubber surface fluorination modification testing device which mainly comprises an xenon difluoride generating device, a gas flow meter, a pressure meter, a rubber surface fluorination device, a tail gas recovering device, a vacuum pump, a motor, an xenon difluoride recovering device, a throttle valve, a stainless steel pipe, a temperature control panel, a heating plate, a sealing ring, a rubber sample placing frame and other parts. A rubber sample is placed on the rubber sample placing frame and is positioned in the rubber fluorination device, and a defined mount of xenon difluoride gas is introduced to carry out surface fluorination modification on the rubber sample. The rubber fluorination device is vacuumized through the vacuum pump, the throttle valve and the stainless steel pipeline, and an xenon difluoride crystal is heated at certain temperature by using the heating device so as to be sublimated into a gaseous state, the gaseous xenon difluoride enters the rubber fluorination device under the action of a pressure difference, and the rubber sample is subjected to surface fluorination modification. By adopting the rubber surface fluorination modification testing device, rubber is subjected to surface fluorination modification testing under the condition of different temperatures and pressure intensities.

Description

technical field [0001] The invention discloses a rubber surface fluorination modification test device, which is particularly suitable for the research on the surface fluorination modification of improving the wear resistance of rubber sealing parts. The fluorinated modification test device on the surface of rubber samples solves the problem of how to modify the surface of rubber samples under different temperatures and pressures, and can study the influence of temperature and pressure on surface modification. Background technique [0002] Rubber, together with plastic and fiber, is called the three major synthetic materials, and is the only polymer material with high elasticity and excellent elasticity. The biggest feature of rubber is that the modulus of elasticity is very small and the elongation is very high. The second is that it has fairly good gas permeability resistance, resistance to various chemical media and electrical insulation properties. Therefore, rubber is ...
