Description

technical field

[0001] The invention relates to the application field of plasma technology, in particular to a plasma surface treatment device for particles and powder materials. Background technique

[0002] Material surface modification technology is one of the commonly used material preparation technologies at present. Its basic principle refers to the use of physical, chemical, mechanical and other methods to treat the material surface or interface, and purposely change the physical and chemical properties of the material surface, such as Surface energy, surface wettability, electrical properties, adsorption and reaction characteristics, surface structure and functional groups, etc., ultimately meet the needs of new materials, new processes and new technologies. For granular and powder materials, surface modification methods are more limited than for other shaped materials.

[0003] At present, the methods for surface treatment of particles and powder materials are usua...
