Claims16
A cleaning material of a color cathode ray tube panel, comprising an acidic water-soluble solution and a surfactant.
A cleaning material of a color cathode ray tube panel having fluorescent film, graphite film, intermediate layer or metallic reflection film inside, comprising an acidic water-soluble solution, an inorganic acid, a surfactant and a builder.
A process to use a cleaning material of a color cathode ray tube panel having fluorescent film, graphite film, intermediate layer or metallic reflection film inside, the cleaning material comprising an acidic water-soluble solution, an inorganic acid and a surfactant, wherein the process comprises steps of:
- mixing the cleaning material with a pure water to reach a desirable concentration;
- applying the mixed cleaning material to the panel and leaving it for a desirable period of time sufficient to remove the metallic reflection film;
- applying another cleaning material for eliminating the intermediate layer to remove the intermediate layer at a non-efficient side;
- clearing residual chemicals and removing the metallic reflection film at an efficient side by washing the panel with a tap water;
- applying the mixed cleaning material to the panel again to remove the graphite film and the fluorescent film at both of the efficient and the non-efficient sides;
- and
- conducting a rinsing process with the tap water and the pure water.
A process to use a cleaning material of a color cathode ray tube panel having fluorescent film, graphite film, intermediate layer or metallic reflection film inside, the cleaning material comprising an acidic water-soluble solution, an inorganic acid and a surfactant, wherein the process comprises steps of:
- diluting the cleaning material with a pure water;
- and
- applying a supersonic field to the panel to remove the fluorescent film adhered to the panel.
A process to use a cleaning material of a color cathode ray tube panel having fluorescent film, graphite film, intermediate layer or metallic reflection film inside, the cleaning material comprising an acidic water-soluble solution, an inorganic acid and a surfactant, wherein the process comprises steps of:
- diluting the cleaning material with a pure water;
- and
- generating air-bubbles in the cleaning material to remove the fluorescent film adhered to the panel.
