step four: rolling, namely rolling the steel wire mesh cloth treated in the third step through rolling equipment;
step five: and (3) wire beating, namely placing the wire mesh plate subjected to the fourth treatment on a fixed platform, peeling the film plated in the third treatment, standing for stabilization, and cutting by a laser cutting machine.
Further, the cutting procedure in the step one may use one or more of mechanical shearing and laser cutting.
Furthermore, in the compounding step in the second step, before compounding, a hot melt adhesive sheet is required to be added between the massive steel wire mesh and the polyester mesh.
Further, the fuse wire procedure in the third step can be completed through one treatment process of chemical etching, electrolytic corrosion, laser etching and physical sand blasting; and 3, the gauze of the wire mesh line area treated in the step three is uniform, and the diameter deviation of the gauze is smaller than 0.5 micron.
Further, in the rolling procedure of the fourth step, the block-shaped wire mesh cloth can be rolled through oil pressure equipment, and the rolled wire mesh cloth can be directly rolled through hydraulic equipment.
