Why is plasma power also used for surface treatment of powder:
The surface treatment of the powder material using plasma power can enable the surface of the powder to achieve the effects of etching, activation, impurity removal, grafting, crosslinking, and coating, thereby changing its structure and chemical composition. There are mainly two types of powder materials: organic powder and inorganic powder. Now Chengfeng Zhizao will introduce the role of plasma power in the surface treatment of organic powder.
The surface treatment of organic powder materials is usually based on inhibition to make the organic powder more dispersed and more compatible in the polymer. Therefore, the composite material formed by it and polymer has good performance in terms of force, light, electricity and so on. When the plasma power source performs surface treatment on organic powders, polymer monomers and initiating gas mixed discharge are generally used. In this method, the discharge initiates the gas to generate active particles, and can initiate the grafting of polymerized monomers to the powder surface to form a modified coating layer.
In addition to processing ordinary oxide organic powders, it can also process certain materials such as carbon fiber, activated carbon, and carbon nanotubes. Oxygen plasma is used to process the nano-carbon fiber material, and the mechanical properties of the treated carbon fiber and polypropylene are much better than that of the untreated one. In addition, under normal circumstances, after the carbon nanotubes are treated with a plasma power source, the dispersion and compatibility of the composite material can be significantly improved.
Chengfeng Zhizao focuses on the research and development of plasma cleaners. If you want to know more product details or have questions about the use of the equipment, please click "Online Customer Service", and look forward to your call!
