Automatic Device for Determination of the Specific Surface of the Powder and Gas permeability of Porous Materials

摘要

Presented is an automatic device (PSKh-8A PS) for precise determination of the specific surface of powders, middle-size particles and gas permeability of porous articles proceeding from the permeability value. Developed is a theory and a method fro measuring the true specific surface of highlydispersed powders using gas permeability method. The device contains dynamometric gasket which provides a succesful measurement procedure. The device is covenient, precise and necessitates low labor-consumption.
