Vacuum coating technical analysis

Vacuum coating technical analysis

Compared with the traditional method of plating, vacuum coating technology has many advantages, such as adornment effect is good, strong metal feeling, the cost is low (about 1/3 to 1/2 of traditional electroplating), small pollution, vacuum evaporation coating machine is easy to operation, etc. Especially on the application of nonmetallic objects, has incomparable advantage over traditional electroplating. In view of this, vacuum coating has been widely used in all kinds of plastic, ceramic, glass, wax, wood products, such as surface metallization. The development of vacuum coating technology and vacuum coating of oil development success is inseparable. In a sense, we can say, even without vacuum coating of oil, there is no vacuum coating. Light coating machine which is decided by the effect of vacuum coating of oil. In the process of vacuum coating, vacuum coating machine coating of oil to play the role of a strong bonding pieces and metal film plated (i.e., as the plating pieces of floor coating); After vacuum coating, should be coated with a layer of oil coating on the surface of the plating, then the oil and protect the metal film and dyeing effect (i.e., as a plating coating).
Most of the material before a coating, must be coated with a thin layer of oil coating on the surface of the plating, thoroughly dry again after coating, otherwise, the plating on the metal film falls off easily, multi arc ion coating machine with the hand gently wipe away. In the process of vacuum coating, coating quality depends greatly on the quality of the coating. Vacuum coating technology in the application of plastic products is the most widespread. Plastic has easy molding, low cost, light weight, no corrosion and other characteristics, widely used plastic products, but because of its disadvantages restricted the expand application, such as not beautiful, easy to aging, poor poor mechanical properties, heat resistance, bibulous rate is higher. Through the application of vacuum coating technology, plastic surface metallization, combine organic materials and inorganic materials, greatly improved its physical and chemical properties.
