(Summary description)Application of plasma plasma cleaning machine low temperature plasma activation technology in surface treatment of materials: In recent years, in order to improve the surface viscosity of organic materials, such as the treatment of rubber surfaces, the plasma plasma cleaner technology has been reduced and miniaturized, and the "hot arc" has been changed to "cold arc" and developed into a jet low temperature Plasma plasma cleaning machine. At present, the outlet temperature (instant temperature) of the spray gun researched by Chengfeng Zhizhi is only 50-80 degrees, and it has begun to be promoted and applied in the home appliance and automobile industries. In industry, such as argon arc welding, air plasma cutting and plasma spraying, plasma plasma cleaner low temperature plasma has been widely used. The core component of this type of device is usually called a plasma torch. Its plasma center temperature is as high as several thousand degrees, which is a thermal plasma. In recent years, in order to improve the adhesion performance to organic materials, such as rubber surface treatment, the plasma torch process has been lowered and miniaturized, and the hot arc has been transformed into a cold arc, and a low-temperature plasma jet plasma cleaning machine has been developed. 1. Atmospheric jet low-temperature plasma surface treatment principle: The air flow of the cold arc plasma jet gun can produce oxygen-based active substances containing a large number of oxygen atoms. These oxygen atoms process the surface of the material and can be separated and attached to the surface of the material. The organic pollutant C, which is converted into carbon dioxide, is removed; at the same time, it can improve the contact performance, thereby increasing the strength and reliability of the connection. Industrial application of low-temperature plasma activation technology in the atmosphere. (a) Pre-welding treatment Stainless steel sheet butt welding is widely used in industry. For example, the inner barrel of a solar water heater is made of 0.4mm stainless steel sheet rolled into a cylindrical shape and welded. In order to meet the welding requirements, the welding part must be cleaned. The current cleaning method is a wet method, which uses a chemical cleaning agent to manually scrub. The cleaning cost is high, the pollution is large, and it is difficult to realize automation. Atmospheric jet low-temperature plasma cleaning activation technology is a dry cleaning technology, applied to the pre-treatment of butt welding of thin plates, which can replace traditional manual chemical cleaning agents, reduce cleaning costs, improve welding quality, and reduce environmental pollution. Automation of welding area cleaning. (B) Surface treatment of plastic sheets, such as wood plastic, is a new type of material that can replace wood, but surface coating is very difficult, which greatly limits its scope of application. If chemical treatment is used, the cost is high and the pollution is large. Therefore, with low temperature plasma cleaning machine, the surface of the material will have obvious changes: the color is slightly lighter, the reflectance is reduced, and the surface is in a matte state; the surface is slightly rough when touched by hand; the adhesion performance of the spray paint is greatly improved . The bonding force before and after plasma treatment can be tested. Test method: Use a scraper to make a scratch on the surface of the part to be tested, and use a soft brush to scrape off the debris on the surface. Use scotch tape to stick the line on the line. There should be no air bubbles between the tape and the sample. Keep it for 1 to 2 minutes, and tear off the tape at a constant speed of 60 degrees. Judge the bond strength by observing the integrity of the scribe line and the square. In our daily life, such as door seals on cars, we often use rubber-processed products. The surface should be painted or woven. If there is no low-temperature plasma treatment, adhesion is not easy. If chemical cleaning is used, it will be offline and pollute the environment. The ideal solution is to use online plasma treatment. (C) The air plasma jet used for glass and metal plates can treat glass and metal surfaces, which can not only effectively remove organic pollutants from floating dust in the atmosphere, but also change the surface performance to make it last long enough. Thereby improving the joint strength of the product. In addition, atmospheric pressure plasma cleaning can be applied to the surface of organic and metal materials.
