The surface treatment technology of silica gel products is very important, besides printing, it is also necessary to do a good job of dust prevention. Because silica gel contains static electricity, it makes the product easily absorb dust, impurities and hair. So how can silicone products solve the problems of static electricity and dust prevention?
Under the influence of static electricity, silica gel is easily stained with dust. If manufacturers use traditional chemical coating methods, the dust-proof and lubricating coating effects can only last for several months. A good method is to modify the oxygen atoms on the surface of silica gel with plasma energy, and change the surface of negative silica gel into positive electrode. Harmless organic chemicals are used in the process, and no polluting waste is discharged, so it is a clean production process. It has the characteristics of low static electricity and high dust-proof effect, and is suitable for watch straps, etc. It can also be used for medical equipment.
Theoretically, there are oxygen atoms on the surface of silica gel with negative electrode and static electricity, and dust particles with positive electrode, so dust particles and electrostatic surface of silica gel can attract each other, which makes it difficult to clean the dust on the surface and affects the appearance of products. In view of the problem that the silica gel surface is easy to be stained with dust, the silica gel products factory devoted itself to research solutions, and found that plasma surface modification technology can improve the performance, and finally succeeded in using plasma-assisted chemical vapor deposition (PECVD) technology to optimize the surface properties of products.
Plasma surface treatment technology is suitable for materials such as fiber, polymer and plastic, and can also be used to clean, activate and etch the surface parts of metal, plastic and ceramic materials to change the physical characteristics of the material surface. The environmental protection process for dust-proof treatment of silica gel products can effectively solve the problems of static electricity and easy dust adhesion of silica gel, and prolong the service life of products. It is a silica gel surface treatment process. It can be applied to all silica gel and related products.
High-energy pulsed plasma magnetron sputtering (HPPMS) is a new type of magnetron sputtering system which combines two characteristics (high-energy) and (pulsed). In the plating process, the power supply plays an important role. By adopting (high energy) and (pulse) discharge methods, it can generate powerful energy with an output voltage as high as 1500V in less than 2 microseconds, just like lightning phenomenon. Because a large amount of ions are released in the process and the internal stress of the coating is eliminated, a thick ion coating can be made without damaging the surface of products or workpieces. This way can improve the ionization rate, that is, improve 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, and produce high-quality and thick ion coatings with a thickness of more than 3 μ m. Because the high-energy pulse mode is beneficial to increase the density of ions, it not only strengthens the bonding force between the coating and the substrate, but also reduces the surface roughness, and can further enhance the wear resistance and reduce the replacement times on the functional components.
For highly decorative silica gel products, it can keep the appearance and be more durable. Therefore, plasma can be effectively used to control the structure of the coating, which is characterized by being deposited on a smooth and compact fine structure, improving corrosion resistance and surface smoothness. Or it can be deposited on complex geometric workpieces to achieve a more uniform coating.
