Vacuum coating technology, green coating technology in the new era
With the world's attention to environmental protection, environmental laws and regulations are increasingly strict. The development of social economy puts forward new requirements to the traditional electroplating industry which with high consumption and heavy pollution, and the electroplating industry is a basic industry, which involves a wide range and cannot be directly banned, so it needs to upgrade its technology. As a green coating technology, vacuum coating is a new technical concept in the field of surface engineering. The integrated technology of vacuum composite coating is used to replace or partially replace the traditional chemical plating technology, so as to achieve the purpose of protecting the environment, reducing consumption, reducing emission and eradicating the pollution of electroplating wastes, solving the contradiction between sustainable development and environment-friendly, and effectively building an environment-friendly and resource-saving society. The vacuum coating technology includes a series of single technologies such as vacuum ion coating, magnetron sputtering coating, evaporation coating, ion implantation, ion cleaning and the integration of multiple composite technologies, involving the multi-disciplinary fields such as vacuum, machinery, control, optoelectronics, material modification, surface engineering, information, etc.
Advantages of vacuum coating technology over traditional electroplating technology: In the past, electroplating and chemical plating were used for coating, not only the thickness is difficult to control, the uniformity of the coating is poor, the adhesion is poor, but also there are serious problems such as three wastes pollution. Today, people's awareness of environmental protection is gradually strengthened, and its development has been restricted by various aspects. The process of vacuum coating technology is simple, environmental improvement, no pollution, less consumables, even and compact film-forming, and strong adhesion with the substrate. Compared with the traditional electroplating method, vacuum coating technology has many advantages, such as good decorative effect, strong metal texture, low cost (about 1 / 3 ~ 1 / 2 of the traditional electroplating), easy operation, etc. Especially in the application of non-metallic objects, it has the incomparable advantages of traditional electroplating. In view of this, vacuum coating has been widely used in the metallization of various plastics, ceramics, glass, wax, wood and other products.
Zhenhua Vacuum adheres to the concept of green coating technology. Over the years, it has focused on the development and manufacture of various vacuum coating machines. In recent years, it has also made great progress in functional material film and composite film. Coating equipment is widely used in aerospace, electronics, optics, machinery, construction, light industry, metallurgy, materials and other fields. It can be used to prepare films with wear-resistant, corrosion-resistant, decorative, conductive, insulating, photoconductive, magnetic, lubricating, superconducting and other characteristics. With the development and manufacture of Zhenhua Vacuum in the vacuum coating machine for many years, Zhenhua has made many breakthroughs in the vacuum coating technology, such as multi arc ion plating and magnetron sputtering composite technology, large rectangular long arc target and sputtering target, unbalanced magnetron sputtering target, twin target technology, strip fiber dimension fabric winding coating technology, etc.
