To produce silicone rubber products that satisfy customers, the surface treatment process is very important. In addition to printing, it is also necessary to do a good job in dust prevention. Because silicone contains static electricity, it makes it easy for the product to adsorb dust, impurities, and hair. So how can silicone products remove static electricity and solve the problem of surface dust prevention?
In theory, there are oxygen atoms on the surface of silicone, with negative electrodes and static electricity, while dust particles have positive electrodes. Therefore, dust particles and silicone electrostatic surfaces can attract each other, making it difficult to clean the surface and affecting the appearance of the product. In response to the problem of dust on the surface of silicone, the silicone product factory is committed to researching solutions. The results show that the use of plasma surface modification technology can improve relevant performance, and ultimately, plasma assisted chemical vapor deposition (PECVD) technology is successfully used to optimize the surface quality of the product.
Due to the influence of static films, silicone is generally prone to dust. If manufacturers use traditional chemical coating methods, the dust and lubrication coating effects can only be maintained for a few months. A good method is to use plasma energy to modify the oxygen atoms on the surface of silica gel, and change the negative electrode silica gel surface to the positive electrode. During the process, harmless organic chemicals are used, which will not discharge polluting waste. Therefore, it is a clean production process. Its low static electricity characteristic and high dust prevention effect are suitable for watch straps, and can also be used in medical equipment.
Plasma surface treatment technology is applicable to materials such as fibers, polymers, and plastics, and can also be applied to clean, activate, and etch the surface of metal, plastic, and ceramic materials, changing the physical characteristics of the material surface. The dust-proof and environmentally friendly process of silicone products can effectively solve the problems of silicone static electricity and easy dust contamination, extend the product life, and is a silicone surface treatment process. It can be applied to all silicone and related products.
High energy pulsed plasma Magnetron sputtering technology (HPPMS) is a new type of Magnetron sputtering system that combines the characteristics of "high energy" and "pulsed". In the plating process, the power supply plays an important role, using "high energy" and "pulse type" discharge methods, which can emit powerful energy with an output voltage of up to 1500V in a short time of less than 2 microseconds, like a lightning phenomenon. Due to the release of a large amount of ions during the process, the internal stress of the coating can be eliminated, making it possible to produce thick ion coatings that do not damage the surface of products or workpieces. This method can improve the ionization rate, which means improving the adhesion of the coating on the surface of the product.
High energy pulsed plasma Magnetron sputtering technology can surpass the traditional Magnetron sputtering method to produce high-quality products more than 3 μ Thick ion coating of m. Due to the advantage of high-energy pulse method in increasing ion density, it not only enhances the bonding force between the coating and the substrate, but also reduces surface roughness. In functional components, it can further enhance wear resistance and reduce replacement times.
For highly decorative silicone products, it can maintain appearance and be more durable. Therefore, using high-energy pulse coating can effectively utilize plasma to control the structure of the coating. Its characteristic is that it can be deposited on smooth and dense microstructure, improving corrosion resistance and surface smoothness. Alternatively, it can be deposited on complex geometric workpieces to achieve a more uniform coating.
