The principle of vacuum coating machine cooling system

The principle of vacuum coating machine cooling system

Vacuum coating equipment the metal cover body by mounting holes and then fixed in the form of welding in the external walls of vacuum coating machine, for the cooling of the outer wall by strengthening circular groove formed channel, so that ensure the circulation of cooling, also avoid the phenomenon of blind Angle, effective to the rapid cooling of coating machine, reduces the temperature of the oil pump, to strengthen the cooling intensity, simple structure, safety and reliability etc, in the vacuum coating machine cooling case including the metal cover body is the cause of a number of an orderly, and the strengthening of concave circular groove, strengthening circular groove is described hemispherical or conical shape; It is to strengthen existing circular groove bottom sets with connection of vacuum coating machine for cooling of the outer wall mounting holes, described the metal cover body through the mounting hole and fixed in welding way outside the existing vacuum coating machine for cooling wall, it is between the outer wall of the metal cover body and stay cool through strengthening circular groove constitute circulation channel, the vacuum coating machine according to claim 1 circulating cooling system with cooling case, its characteristic is that it is the metal cover on the vertical and horizontal spacing between two referred to strengthening circular groove is 100-300 mm, the strengthening circular groove 12 _15mm deeply, as described in the thickness of the metal cover body is 2-5 _, the vacuum coating machine according to claim 1 circulating cooling system with cooling case, its characteristics is described in the strengthening of circular groove 24-136 - mm in diameter.
Vacuum coating machine mainly refers to in the case of high vacuum coating, has been widely used, the system of film especially widely, its production of thin film has been applied to various kinds of photoelectric system and optical instruments, digital camera. Binoculars, and used in automobile industry and other industries.

Vacuum coating machine film uniformity concept

Vacuum coating machine film uniformity concept

1. The thickness uniformity, also can understand as roughness, on the standard of optical thin film to watch (that is 1/10 of a wavelength as a unit, which is about 100 a), the uniformity of vacuum coating machine has been pretty good, easy to manipulate roughness in 1/10 of the visible light wavelength range, that is said about the optical properties of thin film, vacuum coating not any way. But if standard is refers to the atomic layer on the uniformity, which is said to complete 10 a and 1 a the appearance of smooth, detailed control elements detailed explanations are given here is on the basis of different coating.
Uniformity on 2. Chemical composition: that is said in the film, compound of atomic group branch occurs as a result of the standard is too small and very simple homogeneous characteristics of SiTiO3 film, if coating process is not scientific, so not SiTiO3 practice appearance of components, and is likely to be other share, membrane plating membrane is not want chemical composition, it is also a vacuum coating place of skill levels. The detailed elements are given below.
3. The uniformity of the lattice degree of order: this resolution the film is a single crystal, polycrystalline, amorphous, and is the hot issue in vacuum coating skills, detail see below.
Primary classification, there are two big kinds: transpiration accumulated mass of coating and sputtering coating, contains many varieties in detail, include vacuum ion transpiration, magnetron sputtering, MBE molecular beam epitaxy, sol gel method and so on.

Vacuum coating machine coated glass little knowledge

Vacuum coating machine coated glass little knowledge

Application of the coated glass is one of the most heat reflective glass and low radiation glass. Basically adopts the vacuum magnetron sputtering and chemical vapor deposition method, two kinds of production methods. Since the late eighty s, our country there have been hundreds of coated glass production factory, influential in the industry production such as vacuum magnetron sputtering method, chemical vapor deposition method
Magnetron sputtering coated glass magnetron sputtering technology can be used to design and manufacture of multilayer complex film system, can be in the white glass substrate coated with a variety of color, the membrane layer has good corrosion resistance and wear resistance, is one of the most popular product at present production and use.
Vacuum evaporation coating glass varieties and quality compared to the magnetron sputtering coating glass, there is a certain gap has been gradually replaced by vacuum sputtering. Chemical vapor deposition method is in float glass production line to the reaction gas on the surface of the glass that heat decomposition, uniformly deposited on the glass surface coated glass.
The method is characterized by less investment of equipment, easy control, product cost is low, good chemical stability, can be hot working, is one of the most promising methods of production. Making sol-gel coated glass production process is simple, the stability, the deficiencies are product high light transmittance, adornment sex is poorer.

The meaning of vacuum coating machine maintenance

               

As everybody knows, vacuum coating machine running status will directly affect the quality of coating products, in order to better operation, to the vacuum coating machine maintenance and maintenance, so, then know the meaning of the vacuum coating machine maintenance and maintenance? Underneath, small make up to explain the meaning of them.
  The daily maintenance of equipment maintenance is not normal phenomenon, found in production to solve as soon as possible. Mechanical pump oil found reduced to add, don't think oil regularly to replacement, or to maintain, pump rotor may wear. For example, some bearing the workpiece bogie card, to replace the bearings, or wait until it is completely broken, problems are big, may appear problem such as motor burn down.
 Regular maintenance, some people will ask what is the difference between a routine maintenance and regular maintenance? In fact, each device has a service life, for example, the use of silicone oil diffusion pump, for the life of two years or so, we early replacement, is this waste? Not, the most don't want to appear in the production of equipment failure, the daily maintenance and regular maintenance of all ready, not only extend the service life of the equipment, also reduced the operation failure, improve production efficiency. Equipment  maintenance and maintenance of the most important is careful, this can be engaged in the maintenance.
