Design of New Type Measurement Device for Wood Gas Permeability
Li Ta · Research and Exploration in Laboratory · 2014
Nowadays,there are some lots research and experimental teaching needs for the testing of wood gas permeability in the major of wood science and technology. For To achieving achieve the goal of quick and simple operation,under the precondition of ensuring the reliability and comparability of the results,we adopted the key technologies such as the method of specimen clamping,including the wood sample preparation and,the clamp structure, and the installation pattern for attaching the clamp to the testing system were specially considered in the design process. The metal hole saw and type D and F quick coupling,which could be commonly got in the market,were successfully utilized in the development of this new kind of measurement device for gas permeability of wood.
