Atmospheric pressure plasma surface treatment machine
As soon as atmospheric pressure plasma surface treatment machine came out, it has been welcomed and favored by many industries, because it can carry on certain physical and chemical modification to the surface, and can improve the surface adhesion to a certain extent. Its role can be said to be quite large, the following industries need to use atmospheric pressure plasma surface treatment machine. First, as we all know, the printing and packaging industry provides customers with a wide variety of packaging boxes. If these boxes are not handled properly, it is easy to have the problem of unglue, which has a great impact on the profits of enterprises. If the plasma processor is used, the problem of unglue can be avoided effectively, the surface of various materials can be treated, and the grinding pollution can be greatly reduced, and consumables can be saved to a certain extent, of course, the cost of glue can also be saved. Two, in the digital industry is also the need to use atmospheric pressure plasma surface processor, if it is used to spray the shell of digital products, can make the display screen bonding more firmly, will not appear unglued problem, can greatly improve the surface of the adhesive force, effectively prevent the digital product shell degumming phenomenon. Three, also need to use in the manufacturing industry atmospheric pressure plasma surface treatment machine, understand the car must have a good air tightness, using pneumatic type plasma processor can for car doors and Windows, air conditioning and other preprocessing part part and then spray adhesive, to increase the car's air tightness, for waterproof insulation has a good effect. Four, there are many metal products in the hardware industry, if the surface of them is modified by the processor, it can not only prolong their service life, but also greatly improve their wear resistance. This shows that the application range of atmospheric pressure plasma surface treatment machine is very wide, perhaps in the near future, there will be more industries to use it, its coverage will be bigger and wider. If there is a demand for use, you can buy from a regular manufacturer.

What is the function of plasma surface treatment equipment
Plasma surface treatment equipment provides the ability to change the surface of a material to improve surface energy, adhesion, printing and wetting. The plasma also provides the ability to coat a water-resistant product. In fact, almost any material can be treated with plasma. The contaminants treated by plasma surface treatment devices are usually invisible and on the nanoscale. This contamination can affect an object's ability to interact with other substances, such as glue or ink. Using plasma to treat the surface of the object, organic matter can be removed. Plasma surface treatment equipment can improve the bond or solder bonding strength, improve the reliability of printing. This process is suitable for shiny plastics and rubber, which can be printed and bonded after impurities are removed. What is the role of plasma surface treatment equipment? Surface Activation and Etching of Materials: Any plasma surface modification method without chemical treatment is called dry etching. All plasma cleaning products are dry etched during the plasma etching process. Plasma etching is similar to plasma cleaning. In plasma etching, however, the purpose is to remove the treated surface layer impurities. Plasma surface treatment: Oxygen plasma treatment is a commonly used dry etching method at present. Oxygen (sometimes mixed with argon) is used to treat aluminium, stainless steel, glass, plastics and ceramic surfaces. Plasma activation: Slight changes to the activated surface allow for better printing or bonding. Etching machines allow plasma erosion of printed circuit boards to improve their adhesive properties, such as adhesion and veneability. Plasma surface modification: Plasma surface treatment equipment modification refers to the cleaning of the product to improve its printing or bonding ability. The purpose of plasma cleaning is to remove organic contaminants from the surface. Plasma treats the surface of your product to accept adhesives or printing inks. Often used to modify the surface of polytetrafluoroethylene or plastic plasmas, it actually changes the surface of the material, leaving free radicals that stick to the glue or ink.
