As is well known, industrial chillers are suitable for various industrial refrigeration needs, such as plastics, textiles, electroplating, vacuum coating, and many other industries. They are mainly used to control temperature and cool down equipment to maintain normal operation. Below is the specific application of industrial chillers in the vacuum coating industry analyzed by the editor.
1、 Working principle of coating chiller
The working principle of coating is the crystallization of the film body that evaporates and falls on the surface of the workpiece at high temperature. Due to the resistance of air to the evaporated membrane molecules, collisions can cause the crystal to become rough and matte. Therefore, it is necessary to maintain a high vacuum to make the crystal fine and shiny. If the vacuum is not high, the crystal will lose its luster and have poor adhesion.
Early vacuum coating relied on the natural scattering of the evaporator combined with poor work efficiency and low gloss. Now, with the addition of intermediate frequency magnetron sputtering targets, the evaporated molecules of the film are accelerated by magnetron sputtering targets under the action of an electric field to bombard the target material, splashing out a large number of neutral target atoms or molecules onto the substrate to form a film. This solves the problem of film varieties that cannot be processed by natural evaporation in the past, such as titanium plating and zirconium plating.
2、 The importance of chillers for vacuum coating
Due to the low temperature required for film crystallization during vacuum coating process and the need to maintain temperature stability, the chiller can effectively meet this requirement. In specific use, the chiller can effectively adjust the temperature, control the stable temperature of the vacuum coating machine, and achieve the goal of high plating quality.
If a chiller is not used, it will affect the overall operating efficiency and quality of the vacuum coating machine, making it unable to work stably. Therefore, in the vacuum coating industry, it is recommended to use matching chillers for temperature monitoring to improve product accuracy and quality.
3、 Improving the efficiency and quality of vacuum coating
The coating chiller has a completely independent refrigeration system, and the water temperature can be adjusted and controlled within the range of+3 ℃ and 35 ℃, thus achieving high-precision and high-efficiency temperature control to ensure product quality. Therefore, the quality of industrial chillers determines the working quality and efficiency of vacuum coating machines, and corresponding chiller production enterprises need to pay attention to the specific quality of chillers.
Industrial chillers have shown great superiority in improving the quality of vacuum coating. Therefore, the efficient utilization of industrial chillers further ensures the overall stability of vacuum coating operation.
