Manufacturing method of nanometer protective coating on surface of metal plate

Abstract

The invention provides a manufacturing method of a nanometer protective coating on the surface of a metal plate. Spraying equipment for nanometer protective coating on the surface of the metal plate comprises a clamping mechanism, a spraying mechanism and a box body mechanism, the clamping mechanism is arranged in the interior of the box body mechanism, the spraying mechanism is arranged right above the clamping mechanism, and the spraying mechanism is arranged in the interior of the box body mechanism. The manufacturing method solves the following problems, frequently existing when the nanometer protective coating on the surface of the metal plate is manufactured at present, that 1, the metal plate is inconvenient to fix, the clamping requirement of a curved plate cannot be met, and the spraying treatment of the surface of the plate is hindered; 2, spraying is carried out only for one face, the other face needs to be manually turned over and replace the one face to be sprayed, the process is tedious, and the face cannot be automatically turned over; and 3, when a spraying nozzle atomizes coating, the coating particles are not uniformly atomized, and an air injection channel on the spraying nozzle cannot be closed and controlled.

Description

technical field [0001] The invention relates to the technical field of metal plate processing, in particular to a method for manufacturing a nano protective coating on the surface of a metal plate. Background technique [0002] Metal plate is a kind of plate, which is used as a component of walls, ceilings or floors. It also refers to forged, rolled or cast metal plates, which are divided into thin plates, medium plates, thick plates and special thick plates, usually made of Flat rectangular building material panels and curved building material panels in standard sizes; [0003] Metal sheet is mainly used in building decoration, it can not only decorate the outer surface of the building, but also protect the finished surface from the erosion of rain and snow, especially for some new wall materials, in order to ensure the durability of the metal sheet Aesthetics and durability, using the existing coating technology, adding nano-materials to the performance of the coating, so...

AI Technical Summary

Problems solved by technology

[0005] 1. It is inconvenient to fix the metal plate, which cannot meet the clamping requirements of the curved plate, and hinders the spraying treatment of the surface of the plate;

[0006] 2. Spraying is only done on one side, and it needs to be turned over manually to spray on the other side. The process is cumbersome and cannot be turned over automatically;

[0007] 3. When the nozzle atomizes the paint, there is the problem of uneven atomization of the paint particles, and the air spray channel on the nozzle cannot be closed and controlled; for this reason, the invention provides a method for manufacturing a nano-protective coating on the surface of a metal plate
