Processing method of vacuum equipment adopting laser cladding technology

Abstract

The invention relates to a processing method of vacuum equipment adopting a laser cladding technology. The processing method comprises the following steps: (1) carrying out laser cladding treatment on the inner wall of a vacuum drying tank, specifically, a robot clamps a laser, and operates in the vacuum drying tank, a cladding material is added into a molten pool formed after a substrate is irradiated by laser in a manner of synchronously or presetting the cladding material, the cladding material and the vacuum drying tank are jointly and rapidly solidified to form a coating layer on the inner wall of the vacuum drying tank, and the cladding material is a wear-resistant, high-temperature-resistant and corrosion-resistant inorganic non-metallic material; (2) hole filling treatment is conducted on the coating layer, specifically, numerous particle gaps exist in the coating layer, hole filling agents are filled into the particle gaps and cured, and the hole filling agents are made of abrasion-resistant, high-temperature-resistant and corrosion-resistant high polymer materials. According to the processing method of vacuum equipment adopting a laser cladding technology, the vacuum drying tank is suitable for drying materials with the requirement for the ppm level or above of the metal ion content.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a processing method of vacuum equipment using laser cladding technology. Background technique [0002] In the graphene lithium battery industry, there is a high requirement for the metal ion content in the battery material. The general requirement cannot exceed 50ppm, and the higher requirement cannot exceed 10ppm. [0003] Common dryers on the market include a vacuum drying tank. The inner cavity of the vacuum drying tank is used to place the material to be dried. The solvent in the material is evaporated by heating the vacuum drying tank to achieve a drying effect; when drying the material, the material It is in direct contact with the inner wall of the vacuum drying tank made of metal. If a common dryer on the market is used to dry materials that require ppm or higher metal ion content, the metal ion content of the dried material will exceed the standard, which will f...

Problems solved by technology

[0003] Common dryers on the market include vacuum drying tanks. The inner cavity of the vacuum drying tank is used to place the material to be dried. The solvent in the material is evaporated by heating the vacuum drying tank to achieve a drying effect; when drying the material, the material It is in direct contact with the inner wall of the vacuum drying tank made of metal. If a common dryer on the market is used to dry materials that require ppm or higher metal ion content, the metal ion content of the dried material will exceed the standard, which will further affect the terminal.
