Surface treatment process of silica gel products

Now the demand for the product is getting higher and higher, the product should not only have the appearance of the appearance, but also have the connotation (functional), and the environmental protection!

If the enterprise can add the above three elements in the product, it will greatly expand the market share!

In these three elements, the color value is the most intuitive factor to attract consumers. Yan value is closely related to the surface treatment technology of products. Recently, the Hongkong Productivity Council launched the new surface treatment technology for silicone and electroplating products, which can greatly improve product functions.

The oxygen atom on the surface of silicone machine is modified by plasma energy, and the surface of negative electrode silica gel is changed to positive pole

Environmental protection technology of silica gel products

Silica gel is a heat-resistant rubber that can withstand high temperature. Compared with other materials, silica gel has the characteristics of biocompatibility, and the product is quite durable. It is suitable for food, medical and industrial industries. But the surface of silica gel is easy to dust. Manufacturers usually use chemical spraying to make the surface of silica gel product duer and smoother, but this process is not only expensive, but also affects the ecological environment and endanger human health.

Theoretically, there are oxygen atoms on the surface of silica gel, with negative electrodes and static electricity, and dust particles have positive electrodes. Therefore, the electrostatic surface of particles and silica can attract each other, making the surface dust and difficult to clean up, affecting the appearance and efficacy of products. According to the silica surface easily stained with dust, HKPC R & D team committed to research solutions found by plasma surface modification technique can improve the performance, the ultimate success of the plasma assisted chemical vapor deposition (PECVD) technology, to optimize the product surface properties effect.

Dr. Lu Weixian, a senior consultant in the Ministry of intelligent manufacturing and materials technology, pointed out that under static film, silica gel is easy to be stained. If manufacturers use traditional chemical coating methods, dustproof and lubricating coating effects can last for only several months. The new method is to modify the surface of oxygen on the surface of silica gel by plasma energy, and change the surface of negative silica gel to positive electrode. In the process, harmless organic chemicals will not be discharged, so it is a cleaner production process. Its low static electricity characteristics and high dustproof effect are suitable for high-end products, such as eyeglass frame, watch strap, etc., and can also be used for medical equipment and sports products, so that these products will perform better.

Plasma surface treatment technology is suitable for materials such as fiber, polymer and plastic. It can also be applied to clean, activate and etch the surface part of metal, plastic and ceramic materials, and change the physical characteristics of material surface. It is a green surface treatment process that can effectively solve the problems of silica gel electrostatic, easy to dust and prolong the life of the products. It can be applied to all silica gel and related products.

Low cost production scheme for thick ion plating

High energy pulsed plasma magnetron sputtering (HPPMS) is a new magnetron sputtering system which combines the two characteristics of "high energy" and "pulse type". The power supply plays an important role in the coating process. The high energy and pulse mode discharge can generate a powerful energy up to 1500V output voltage in the short time of less than 2 microseconds, just like the lightning phenomenon. Due to the release of a large number of ions in the process, the internal stress of the coating is eliminated, so a thick ion coating can be made to damage the surface of the product or the workpiece. This method can improve the ionization rate (IonizationRate), that is, to improve the adhesion of the coating on the surface of the product.

High energy pulse plasma magnetron sputtering technology can surpass traditional magnetron sputtering, and produce high quality more than 3 m thick ion plating. Because the high energy pulse mode increases the density of ions, it not only strengthens the bonding force between the coating and the substrate, but also reduces the surface roughness. It can further enhance the wear resistance and reduce the replacement times on the functional parts.

For decorative products, can maintain the appearance and more durable, so the high energy pulse produced by plasma coating, can effectively, so as to control the structure of coating, its biggest characteristic is can be deposited in the fine structure of smooth and compact, improve corrosion resistance and surface smoothness; or it can be deposited in on the geometry of complex workpieces, achieve more uniform coating.
