Abstract
The invention relates to a method for removing at least part of at least one layer of a composite coating that is formed of fibers and at least one resin that is present on the surface of the body of a gas cartridge. In said method, at least one liquid nitrogen stream is dispensed at a temperature less than −100 DEG C at a pressure of at least 00 bars upon contact with said coating so as to remove at least part of said coating layer present on the body of the gas cartridge.
Claims12
A process for removing at least some of at least one layer of a composite coating present on a surface of a gas cylinder, in which said composite coating is brought into contact with at least one liquid-nitrogen jet at a temperature below −100° C. and at a pressure of at least 500 bar, so as to remove at least some of at least one layer of the composite coating, wherein said composite coating is formed from fibers and at least one thermosetting or thermoplastic resin, and said fibers are selected from the group consisting of glass, basalt, carbon or aramid fibers.
