As we all know, 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 the temperature and keep the equipment in normal operation. The following is the specific application of industrial chillers in the vacuum coating industry, which is specifically analyzed by the Kedley chiller.
1、 Working principle of coating chiller
The working principle of the coating is that the film body evaporates and falls on the surface of the workpiece to crystallize under high temperature. Because the air will produce resistance to the evaporated membrane molecules and cause collisions, making the crystal rough and lusterless, the crystal must be made fine and bright under high vacuum. If the vacuum is not high, the crystal will lose luster and the binding force is very poor.
The early vacuum coating was based on the combination of natural scattering of the evaporator and poor work efficiency and low gloss. Now, with the addition of the medium frequency magnetron sputtering target, the magnetron sputtering target will accelerate the impact of the evaporated molecules of the film body on the target under the action of the electric field, and eject a large number of target atoms or molecules with neutral target atoms to deposit on the substrate to form a film, which solves the problem of the film body varieties that cannot be processed by natural evaporation in the past, such as titanium and zirconium plating.
2、 Importance of chiller to vacuum coating
As the crystallization of the film body needs low temperature to meet the requirements in the vacuum coating process, and the temperature needs to be stable, the chiller can well meet this demand. In specific use, the chiller can effectively adjust the temperature and control the stable temperature of the vacuum coating machine, so as to achieve the goal of high plating quality.
In any case, if the chiller is not used, the overall operation efficiency and quality of the vacuum coating machine will be affected, and it cannot work stably. Therefore, in the vacuum coating industry, try to use matching chillers for temperature monitoring to improve product accuracy and quality.
3、 Improve the efficiency and quality of vacuum coating
The coated water chiller has a completely independent refrigeration system, and the water temperature can be adjusted and controlled within the range of+3 ℃ and 35 ℃, so that the product quality can be guaranteed with high accuracy and high efficiency. Therefore, the quality of the industrial chiller determines the working quality and efficiency of the vacuum coating machine, and the corresponding chiller manufacturers need to pay attention to the specific quality of the chiller.
