GAS REMOVER PRECURSOR AND ITS USING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a gas remover precursor that prevents deterioration in gas removal performance even if it is left in the atmosphere and can be used as a gas removal material by being subjected to a simple processing step as required, and to provide a method for its use.

SOLUTION: The gas remover precursor 1 is formed by sealing the gas removal material 2 absorbing gas by gas barrier materials 3 and 4 impermeable to gas. The method includes the processing step in which the barrier property of the gas barrier material of the gas remover precursor is lowered to allow the permeation of gas, and a removal process in which the gas remover precursor subjected to the processing step is brought into contact with gas to remove the gas. This prevents deterioration in gas removal performance even if the gas removal precursor is left in the atmosphere, and eliminates the need to discard an unused gas remover precursor after the work of one day is completed.
