Vacuum coating machine vacuum measurement of non-uniform environment

Vacuum coating machines, vacuum coating machines in practical systems, there is a source to pump gas from the air, and some of these air flow through the drain hole injection, but also some flow effects caused due to various outlet. Not only can a variety of vacuum pumping gas, and vacuum gauge and clean surfaces also have the role of adsorbed gas. Therefore, the actual vacuum system is generally non-uniform airflow distribution. The gas flows through the tubular conduit pipe bunching will be led into the container flow distribution is more uniform. Rarefied air flow vacuum system affects the non-uniform distribution, has been the subject of detailed study in recent years, and these findings are also promoting the development of accurate measurement of gas pressure technology.
In general, we discuss pressure measurement, virtually has assumed two conditions:
① In an envelope, independent of their density and air flow direction and position of the unit solid angle, in a given spatial point there is only one pressure, the pressure independent of the pressure at this point in the regulation of the orientation. That airflow isotropic Yun assumptions.
② is in all parts of the system at the same temperature, the gas pressure means that the referenced pressure this temperature, i.e. an isothermal assumption.

Vacuum coating technology

Vacuum coating technology is a new technology developed in recent years. The principle of it is solid metal (such as aluminum, etc.) in the condition of high vacuum heat gasification, then to molecules or atoms form sedimentary in the substrate surface, thus forming a thin layer of metal film on the surface of the plating. Due to the metal after gasification evenly distributed in the coating machine cavity in the body, so, usually, the formation of the metal film on the surface of the plating is very uniform.
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. This is decided by the effect of vacuum coating of oil. In the process of vacuum coating, 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 off, with the hand gently wipe away. In the process of vacuum coating, coating quality depends greatly on the quality of the coating.
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), low pollution, easy 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.
