After the chrome plating layer on the gravure roller shaft of the printing machine wears out, the traditional method requires chromium removal and re plating, which is highly polluting and has a long cycle (7 days), and the cost of treating chrome plating waste liquid is high. Daokedao uses Ni-P alloy laser cladding instead of chrome plating, with a coating hardness of HRC55-58, comparable wear resistance to chrome plating, and no chromium pollution, meeting environmental standards. For the Φ 300mm gravure roller shaft, the thickness of the cladding layer is 0.08-0.1mm, the surface roughness is Ra0.04 μ m, the mesh hole replication accuracy is ± 0.01mm, and the printing pattern clarity reaches the level of the original chrome plated roller. The repair cycle is only 24 hours, the cost is 80% of chrome plating, and the lifespan is 1.2 times that of chrome plated rollers. After being applied in a certain printing factory, the annual discharge of chrome plating waste liquid was reduced by 10 tons, the environmental protection cost was reduced by 40%, the pass rate of printed products increased from 95% to 99.5%, and the overlay accuracy was improved from 0.1mm to 0.03mm. This solution has passed VOCs emission testing and is suitable for various roller shaft repairs such as gravure printing and flexographic printing, helping enterprises transform into green production.
