CIF powder plasma cleaners

Principle of powder plasma cleaning machine 

A rotating bottle is integrated into the vacuum chamber of a conventional plasma cleaner to  create a powder plasma cleaner. The RF power supply generates a high-energy disordered  plasma at a specific pressure, which acts on the powder sample contained in the bottle.  Through plasma bombardment, the surface of the powder material is effectively cleaned,  leading to alterations and optimization of its surface properties. 

The application of plasma on powder can intentionally modify its physical and chemical  properties, while preserving the inherent characteristics of the powder material. This enables  the surface of the powder to acquire new attributes, transitioning from hydrophobic to  hydrophilic or vice versa. Consequently, it enhances the surface wetting behavior of the  particles and improves their compatibility at interfaces within a medium. As a result, these  particles exhibit improved dispersibility in water or organic compounds. 

Applications

Powder plasma cleaning machine is mainly used in the following fields: 

Surface treatment of inorganic powder materials: It aims to inhibit powder agglomeration,  enhance its dispersion and compatibility within the polymer matrix. Through surface  modification, the mechanical, optical, and electrical properties of both inorganic powders and  polymer composites can be significantly enhanced. For instance, by employing a mixed  discharge of convergent monomers and initiating gases, plasma can initiate a polymerization  2223 reaction on the powder surface to form a modified coating that ultimately improves the  overall material performance.

Surface modification of organic powder materials: The surface properties of organic polymer  powder materials can be enhanced through plasma treatment, which involves the use of  discharge gases such as argon (Ar), helium (He), oxygen (O2), nitrogen (N2) or air. This  process allows for the introduction of active functional groups on the powder's surface  without compromising its internal structure, resulting in increased hydrophilicity. Such  modification is crucial for subsequent processing and application of the powder.

The adjustment of surface bond energy in polymer powder materials: Because polymer  powders generally have weaker surface bond energies than inorganic powders, they are  more susceptible to plasma treatment. The control of the treatment time and plasma  strength is particularly important to obtain the ideal treatment effect. By plasma treatment,  the wettability of the powder surface can be improved, its bonding strength with binders or  other materials can be increased, and organic pollutants on the surface can be removed.

The susceptibility of polymer powders to plasma treatment is attributed to their relatively  weaker surface bond energies compared to inorganic powders. Therefore, precise control  over treatment time and plasma strength becomes crucial for achieving the desired  treatment effect. Plasma treatment enhances the wettability of powder surfaces, increases  their bonding strength with binders or other materials, and effectively eliminates organic  pollutants from the surface.

The utilization of plasma surface treatment for the functionalization of powder materials: The  plasma surface treatment technology enables the functionalization of powder materials'  surfaces, including grafting, cross-linking, coating, and other processing techniques. The  active particles generated by plasma react with the powder's surface, introducing new  functional groups or altering the surface structure to impart novel characteristics.

The plasma treatment of powder materials is a crucial technique for material preparation, as  well as the development of new materials, processes, and new products. This method not  only enhances the surface properties of powder materials but also increases their valueadded potential and broadens their application scope.
