Knowledge Of Roller Coating
Reticulated roller 1. Basic knowledge of ceramic roller
Base material: 45# steel
Coating Material: Chromium Trioxide
Coating thickness: 0.25mm≤h≤1mm, generally 0.5~0.7mm is the best
Mesh depth: about 45~50um for 200 lines (1mm-1000um)
Mesh shape and angle: 60° honeycomb type, the side is u-shaped
2. Basic knowledge of metal mesh
Base material: 20# steel
Production process: The electro-engraved roller mesh is mainly formed by laser ablation
The extrusion rod is mainly made of metal hob by mechanical extrusion
Cell shape: truncated pyramid (inverted quadrangular)
The depth of the mesh hole: generally determined according to the mesh wire and the theoretical coating amount; the electric carving reel is shallower for the same number of wires.
When the number of reticulated lines is 200 lines/inch, it is required that the dry amount of feeding and coating can be controlled within the range of 0.35~0.65g/m' (the concentration of the material liquid is 10%);
When the number of mesh spokes is 140 lines/inch, it is required that the dry amount of feeding and coating can be controlled within the range of 0.70~1.00g/m' (the concentration of the material liquid is 10%).
