Gas permeability evaluation method and gas permeability evaluation apparatus

机译:透气度评价方法及透气度评价装置

摘要

PROBLEM TO BE SOLVED: To evaluate gas permeability more quickly by using a metal corrosion method.;SOLUTION: In a test piece, a corrosive metal 2 which is corroded in response to a specific gas is formed on the surface of a film 1, and a non-corrosive metal 3 which does not respond to the gas is formed in such a way as covering a part except a surface with which the corrosive metal 2 is in contact, to seal the corrosive metal 2 by the film 1 and the non-corrosive metal 3. The gas permeability evaluation device of the film includes a test piece storage chamber 19 as a container having an inside where the test piece is stored; and environment maintenance means for maintaining the environment inside the test piece storage chamber 19 at fixed gas concentration, fixed temperature, and fixed pressure higher than the atmospheric pressure.;COPYRIGHT: (C)2012,JPO&INPIT
