[0006] Example: A process method for spraying long-term anticorrosive coatings on cable trays. First, sandblasting is used to remove oil stains and rust on the surface of steel structure cable trays, and then high-pressure airflow is used to blow off the dust left over during sandblasting, and then dry and bake it. After drying, use the oxyacetylene spraying method to melt the aluminum wire and spray it evenly on the metal surface of the bridge frame with a thickness of 50-60 microns. Then, in a dry workshop, the fluorocarbon resin bottom layer, middle layer, The surface layer is sprayed layer by layer on the metal surface of the bridge frame that has been dried and sprayed with aluminum. The bottom resin is sprayed twice, the middle layer is sprayed once, and the surface layer is sprayed twice. The coating operation time interval is 4-5 hours, each The standard film thickness is 30-35 microns, and the total thickness of the coating is 150-180 microns. After spraying, store the ca...
