At present, the main production of coated glass?

 At present in China the use of coated glass are the following several ways: 1. Electronic gun evaporation coating machine: Using Thermal Evaporator vacuum coating machine production of coated glass, because overall production is intermittent, after cleaning the glass part are often in the workshop for a period of time before the chamber of plating

Currently, the use of coated glass in our country mainly has the following several ways of production:

1. The vacuum evaporation coating: Using Thermal Evaporator vacuum coating machine production of coated glass, because overall production is intermittent, after cleaning the glass are often in the workshop for a period of time before coating the coating chamber. At this time, the glass will by the secondary pollution, the film is plated on the part of the pollution is easy to fall off, coating uniformity is poor, tend to have a rainbow color and reflectance high. {hottag} and glass plated with a layer of membrane, extremely easy to in the air discoloration and production can not be large size glass. Therefore, the Ministry of construction made clear that such coated glass is not easy to make curtain wall glass. In the home can see many building glass curtain wall of each piece of glass surrounded by white, black, stained stripping stripping is due to incorrectly chose the coated glass caused. Of course, this kind of glass prices are generally in the 80 yuan ~ 100 yuan / m2 can buy. The individual choice of this kind of glass decoration company Kengpian user mou.

2 vacuum magnetron sputtering cathode: flat glass in the vacuum cavity with high vacuum, gas in the negative voltage between the two poles of the positive ions in the orthogonal electromagnetic field under the action of fly to the cathode, a short drop in the cathode area have great energy to the rapid bombardment of the target (target), so that the cathode atoms fly glass substrate, glass deposited film, two electronic sputtering (this process called gamma process) under the action of electromagnetic field in cycloid motion collision ionization, crab derivative carriers, which can Everfount to bombardment cathode, provide enough number of positive ions, the formation of the continuous plasma glow discharge, which can a multilayer coating, with excellent coating uniformity, excellent adhesion and good edge cover. Special mention here is the German "LH" company in the production of coating machine, has a superior and the difference from other vacuum magnetron sputtering coating machine is: it's planar magnetron target magnetic field is produced by an annular permanent magnet, semi-circular annular permanent magnet as the combination of infinite t micro fan columnar magnet. Therefore, the corresponding point magnetic standard potential is more stable, in order to produce a uniform solid coating layer.

3. Solution gel method: also known as double dip coating method, coating method is the impregnation of the glass in the chemical solution and on the surface of the glass formed a layer of film, the chemical coating adhesion on the surface of the glass, the thickness of the film can be 50% of incident ray, off the rest of the reflection and absorption of light by the few. The color of the film coated glass is monotonous, the light transmittance is large, the large area glass film is not uniform, and is not suitable to be used as a curtain wall glass.

4. Powder foam thermal spray process is to retire in solitary glass float glass production line in the water chamber, the metal powder chemical foaming reagent uniform spray directly on the hot glass and reagents overheating after decomposition, on the surface of the glass formed a layer of metal oxide film, this film due to different metal compounds showed different transmission of color and specular color. This kind of coating glass is also called on line coating glass, its cost is extremely low. Because only a layer of film through the string rate, the color is light and dark, in general, only in the color glass coating of green, blue, and because of the volume of colored glass is different, each batch of color changes. The advantage is that this type of coated glass can be directly coupled with the work of hot bending and tempering.

In addition to the above four kinds of coating methods, there are plasma enhanced chemical vapor deposition and arc ion plating method. The two kinds of coating glass are few and are not suitable for building curtain wall glass.

To sum up, with different methods of coating of the glass with different characteristics, the uniformity of the film, the film is also different. Therefore, various methods of production of coated glass is also different.
