Abstract
A method of filling a sealed elastomer chamber (2, 6, 8) with gas is provided, wherein the chamber is filled with the gas chemically produced by thermal decomposition of a gas producing material (12, 14, 16) inside of the chamber itself using a usual means of a high frequency electromagnetic heating. This method is easier than a conventional gas filling method by charging a compressed gas from outside of the chamber to obtain a desired internal pressure in the chamber, and makes it possible to fill more than two sealed elastomer chambers individually with gas at one time.
Claims6
A method for preparing sealed elastomer chambers filled with gas, which comprises the steps of a) placing (A) gas producing composition comprising (1) gas producing material, (2) pyrogenic material being capable of generating heat by eddy current and hysteresis loss induced in magnetic field and (3) binder in the sealed elastomer chambers, b) exposing the composition to magnetic field formed by a high frequency oscillator in order to generate heat in the pyrogenic material, and then c) decomposing the gas producing material to produce gas inside of the sealed chamber, thus filling the sealed chamber with gas.
