1.Vacuum evaporation coating: using thermal evaporator vacuum coating machine production of coated glass, due to the overall production is intermittent, part of the glass after cleaning often must wait for a period of time in the workshop a coating chamber rear can coating, at this point, the glass will be affected by the secondary pollution, caused by the pollution on the part of the plating layer is easy to fall off, the uniformity of coating is poor, easy to have a rainbow of color difference and high reflectivity, and the glass coated with a layer of film, easy to change color in the air and cannot produce large size glass. Accordingly, construction ministry makes clear regulation, this kind of coating film glass makes curtain wall glass not easily. In domestic can see the curtain wall glass of a lot of buildings appears every piece of glass all round is white, black in the middle, scabrous strip is caused by choosing this kind of coating film glass by mistake. Of course, this kind of glass price is low generally in 80 yuan ~ 100 yuan/m2 can be bought. A few decoration company choose this kind of glass to cheat a user for profiteering.
2.
Vacuum magnetron sputtering method: Flat glass in the vacuum chamber with high vacuum, in a negative voltage between the poles of the working gas cations in orthogonal electromagnetic field under the action of fly to the cathode, and a cathode fall short in the area to get a lot of energy to bombard target quickly, so that the cathode (target) atoms flew to glass substrate deposited film layer - glass, sputtering of the secondary electron (this process is called gamma process) in the cycloid motion under the influence of electromagnetic field in collision ionization, crab yan carrier, so it can constantly bombarding cathode, to provide a sufficient number of positive ions, formation of the plasma make sustained glow discharge, it can be done a multi-layer coating, Excellent film uniformity, excellent edge covering and good adhesion. In particular, the coating machine manufactured by LH in Germany is superior to and different from other vacuum magnetron sputtering coaters in that the magnetic field on its planar magnetron target is generated by annular magnets, which can be regarded as a combination of infinite T micro-fan cylindrical magnets. Therefore, the magnetic standard potential of the corresponding points is relatively stable, so that uniform and solid coating can be produced.
3.Solution gel method
also known as two-sided coating method, coating method is to impregnate the glass in the chemical solution, forming a film on the surface of the glass. This chemical film layer adheres to the surface of the glass. The film thickness can be reflected by 50% of the rays, while the rest is reflected and absorbs little light.
4.Powder thermal spraying
the process is to spray the metal chemical powder reagent uniformly directly on the hot glass in the water reducing chamber of the float glass production line. After the reagent is overheated and decomposed, a layer of metal oxide film is formed on the glass surface, which presents different transmission and reflection colors due to different metal objects. This kind of coating glass is also called online coating glass, its cost is extremely low. Because have one film only, pass through string rate is high, colour and lustre is shallower, general and common have the green, blue that coating film is on coloured glass only, and because coloured glass batch is different, the colour and lustre of each batch also has change. Its advantage is that this kind of coated glass can be directly added to work hot bending and toughening.
