Method for forming anti-doping material of shadow mask

摘要

The present invention relates to a method for forming an anti-dipping material for a shadow mask in a cathode ray tube, comprising the steps of inorganic deposition of a anti-dumping substance on the surface of a shadow mask with a binder and an anti-And a step of immersing and drying the washed shadow mask with a dilute water-soluble polymer resin solution. Therefore, there is no variation in the thickness of the coating film, no clogging of holes, and simplification of the working process.
