(Summary description)The principle of using the major functional characteristics of plasma in different industries Low-temperature plasma + photocatalysis technology refers to filling the plasma reactor with TiO2 catalyst. When the high-energy particles generated by the reactor decompose organic pollutants into small molecules, these substances are further oxidized and decomposed into inorganic molecules under the action of the catalyst. Small molecules to achieve the purpose of purifying and separating waste gas. The photocatalyst and the plasma discharge are interrelated. The catalyst can change the properties of the plasma discharge, so that the discharge can produce new active substances with stronger oxidizing power; while the plasma discharge will affect the chemical composition, specific surface area and catalytic performance of the catalyst. structure, improve its catalytic activity, and greatly improve the efficiency of low-temperature plasma + photocatalytic technology to purify VOCs. The combined technology is more suitable for treating organic waste gas with large air volume and low concentration, and has the advantages of low operating cost, fast reaction rate, and no secondary pollution. Plasma surface modification uses the high-energy active particles in the plasma to bombard the surface of the material, giving the surface new properties. Since it only acts on the surface, the original bulk properties of the material remain unchanged. It should be pointed out that plasma has no requirements on the base material, and can be used for surface modification of metal materials as well as insulating materials. Plasma cleaning is the process of cleaning a product to improve its ability to print or bond. The purpose of plasma cleaning is to remove organic surface contaminants. Plasma treats the surface of your product to accept printed adhesives or inks. Usually on Teflon or plastic, plasma surface modification actually changes the surface of the material, leaving free radicals and making it stick to the glue or ink When the plasma interacts with the surface of the object to be cleaned, on the one hand, the plasma or plasma-activated chemically active substances are used to chemically react with the contaminants on the surface of the material, such as the oxidation reaction between the active oxygen in the plasma and the organic matter on the surface of the material. . The plasma interacts with the organic dirt on the surface of the material, and decomposes the organic dirt into carbon dioxide, water, etc. for discharge. When using plasma to modify or clean materials, low-temperature plasma is usually used, and the gas temperature does not exceed 100°, which is macroscopically speaking; but microscopically speaking, when the plasma and the material surface occur, During chemical or physical reactions, if the energy is concentrated in a local area, once the material is processed for too long, it may cause damage to the surface of some materials. Plasma etching technology for fiber structure analysis is the earliest application of plasma treatment in the textile industry and has become a mature technology. Another application is the modification of textile materials, using plasma to modify the surface of textile materials. , graft polymerization and plasma polymerization deposition, etc., to change the surface hydrophilic (hydrophobic) of textile materials, increase adhesion, and improve printing and dyeing properties.
