Problems solved by technology

However, this process is prone to many problems, such as: 1. The surface roughness of the substrate after sandblasting is high, so that the surface of the substrate sprayed with ceramic paint is easy to have obvious pits, especially when the inorganic component in the ceramic paint is larger than When it is more than 20%, the poor appearance of the surface is obvious
2. The area where the sandblasting process is used will be affected by the appearance of the product, and the dead corners or corners of the substrate cannot be sandblasted in place
In addition, sandblasting cannot be performed on thinner substrates

Abstract

The invention provides a shell. The shell comprises a base material and a coating arranged on the surface of the base material. A combination layer is further arranged between the base material and the coating and comprises continuous holes, and the holes are filled with part of the coating. The combination layer of the shell effectively improves the combination force between the base material andthe coating. The invention further provides a manufacturing method of the shell.

Description

technical field [0001] The invention relates to a casing and a manufacturing method of the casing. Background technique [0002] In recent years, ceramic coatings have been widely used in various fields because of their characteristics such as acid resistance, alkali resistance, high temperature resistance, and high hardness. In addition, in order to increase the adhesion of ceramic paint on the surface of the shell, it is usually necessary to perform sandblasting on the substrate. However, this process is prone to many problems, such as: 1. The surface roughness of the substrate after sandblasting is high, so that the surface of the substrate sprayed with ceramic coatings is easy to have obvious pits, especially when the inorganic component in the ceramic coating is larger than When it is more than 20%, poor surface appearance is obvious. 2. The area where the sandblasting process is used will be affected by the appearance of the product, and the dead corners or corners o...
