Abstract

A process for preparing or reparing checkered ceramic roller includes preparing metallic pipe, pretreating surface, blasting sand, spraying prime layer, spraying transition layer, spraying working layer, laser remelting, fine grinding and laser checking. Its advantages are high antiwear and anticorrosion performance, carrying more ink, high checking density and long service life.

Description

technical field [0001] The invention relates to a method for producing and repairing a ceramic anilox roller, in particular to a method for producing and repairing a ceramic anilox roller by using thermal spraying technology and laser technology. technical background [0002] The anilox roller is the core component of the flexographic printing machine, and its geometrical dimension accuracy, wear resistance, corrosion resistance, ink loading, ink release, and service life are directly related to the quality of printed matter. The currently widely used metal anilox rolls have the following serious defects: [0003] 1. Poor wear resistance and corrosion resistance, and the service life is generally about three months; [0004] 2. The small amount of ink storage and uneven ink transfer will affect the printing quality; [0005] 3. The number of mesh lines is low, and it is difficult to print high-definition printed matter. Contents of the invention [0006] The technical p...
