It has long been a concern for researchers to reduce the force of movement of objects inside a fluid for external currents, as well as to reduce the force against fluid flow for internal currents to achieve higher speeds and lower fuel consumption. One of the ways to reduce drag, cover surfaces and convert them to superhydrophobic surfaces. To produce superhydrophobic powders, it is necessary to provide the appropriate conditions for the reaction in certain conditions. One of the sensitivities of this work is the use of metiltricholorosilane for the reaction that the vapor of this material is very corrosive and also provides a lot of sediment that makes it more sensitive to the production of the compartment as well as the components that are in It is used.
In this study, a chamber was constructed for the production of superhydrophobic powders, so as to be able to smoothly resolve the sensitivities of this reaction, specifically silane vapor corrosive.
One of the most important parameters in this reaction is air humidity, due to the presence of silane vapor, most humidity sensors in this chamber lose their effectiveness. For this purpose, using from this property of air that the thermal conductivity of air is change in difference humidity, a sensor was designed and tested. The results of this sensor test indicate that the sensor is the same response to changes in humidity and temperature. Finally, according to the obtained data, a suitable model for this sensor was obtained.
