Shield disk and anti-explosion glass of plane coloured cathod ray tube and their adhesion method

2001 
Object of the present invention is to provide a flat color CRT and a glass panel and explosion bonding method, the manufacturing process to repair by enhancing the adhesion between the panel and the explosion-proof glass and the adhesive force is adjusted to an appropriate size is not qualified panel and the explosion-proof glass, to reduce manufacturing costs, preventing environmental pollution and improve the focus, to improve the contrast. To achieve this object, the present invention provides a flat panel of a color CRT and explosion-proof glass, comprising a thermoplastic resin provided between the panel and the explosion-proof glass for bonding and explosion-proof glass panel. The present invention further provides a method of bonding plane of a color CRT panel and the explosion-proof glass, comprising the steps of: (a) a thermoplastic resin and the explosion-proof glass plate placed on the outer surface of the color CRT panel plane, (b) in the panel , the upper edge of the discharge explosion-proof glass and the thermoplastic resin layers with a closed edge of the layers of vacuum, or the CRT into a vacuum chamber, (c) so that the closed space which is evacuated to form a vacuum state; (d) heating and softening the thermoplastic resin , (e) the pressing of the thermoplastic resin, to eliminate waviness, (f) cooling the heated and eliminate the vacuum state.
