ABSTRACT:
An apparatus for producing a black matrix-type phosphor screen of a cathode ray tube is disclosed, which includes a carbon coating nozzle for coating a carbon slurry on a cathode ray tube panel, a tank for containing the carbon slurry, a supplying system for supplying the carbon slurry from the carbon slurry tank into the carbon coating nozzle and a collecting system for collecting excess carbon slurry produced from the carbon coating nozzle back into the carbon slurry tank, and a carbon slurry regenerating device using an ion-exchange resin is provided. The regenerating device can be placed in at least one of the supplying system, the collecting system and the carbon slurry tank.
