Plasma surface treatment modification technology of powder plasma treatment equipment:
       Low-temperature powder plasma treatment equipment is an effective surface modification technology, which can modify the surface of many materials such as metals, semiconductor polymer molecular materials, etc. This kind of modification has many obvious characteristics: it only occurs on the surface layer, the action time is short, the efficiency is high, it is clean, does not produce pollution, and is easy to operate.


Powder plasma treatment equipment
       It has been widely used in electronics, mechanical textiles, aerospace, biomedicine, etc. The application of nano-materials is a hot spot. Due to the agglomeration of nano-powder materials, the surface modification of nano-materials has also received more and more attention. Powder plasma processing equipment is regarded as a promising method.
       The application of plasma surface modification technology for powder plasma treatment equipment in powder surface treatment is mainly in three aspects: plasma etching, plasma-assisted chemical vapor deposition, and plasma treatment.
       (1) Plasma etching refers to the interaction of plasma and polymer to selectively etch surface molecules, or preferentially etch loose and disordered parts of the surface, which can be used for surface microstructure generation After the change, new functional groups are grafted.
       (2) Plasma-assisted chemical vapor deposition refers to the method of introducing active groups through plasma surface activation, and then forming a new surface layer or forming a thin film on this basis.
       (3) Plasma treatment technology refers to the activation of the material surface or very thin surface layer, and the introduction of chemical functional groups on the surface. Research in this area started earlier, the method is simpler, and more results have been achieved.
       The above-mentioned powder plasma treatment equipment technology has been practical or close to practical applications: polymer surface activation, improving the adhesion of polymer surface and other materials, such as bonding with colorants or paints; used in food or Medical packaging, a transparent medium barrier film that blocks oxygen, water vapor or other aromatic gases; can be used for anti-pilling and pilling treatment of wool or natural fibers to increase the moisture permeability of textiles; used for anti-embolism and antibacterial for artificial blood vessels or catheters Coating; tool hardened soil layer, gas-liquid sensitive film elements, etc.
