Magnetron Sputtering Mirror Coating Production Line
The traditional mirror coating process are the alumiminum evaporation and silvering. By chamber vacuum evaporation machine, we can get an economy home mirror but the reflectivity rate of the mirror can get only 75% to 80%. And by silvering mirror the reflectivity could be increased up to 85% but this process has waste to environment, so it has been stopped by many counties . However, both coating process need a reliable back painting to protect the coating film otherwise the coating will shows the "black point" and separate from glass in some times.
The silvering mirror has a perfect reflectivity but the coating process is very pollution. Therefore, the factories has been stopped by many counties and this kind of process will be forbidden in the nearly future. The aluminium evaporation provide the economy solution however its film cannot stick on the glass very firmly. As well, the back painting contents some lead which is not conformity with none-lead material instructions.
Goldstone Orient New Material & Equipment Co., Ltd. has successfully brings the sputtering coating to the mirror making process. It is an innovation changing on the mirror coating industry.
Sputtering Principle
Sputtering" is a vacuum process used to deposit very thin films on substrates. The large area horizontal on-line sputtering system is designed to continuously coat the metallic or compound layers on glass sheets for the production of reflective glass. The machine is fully automatic controlled and glass is continuously moving and coating from one end of the machine to the other. The available film series are solar control reflective glass, Low-e glass and mirror for a wide variety of commercial and scientific purposes.
The sputtering mirror provide the advantages
The continuous horizontal on-line sputtering system is designed for coating glass sheets with metallic layers to produce the products of aluminum mirror, chrome mirror, home mirror and automobile mirror. The machine is fully automatic controlled and the glass goes inside the machine from one end then goes out from the other end, thus the coating process is continuously worked. The continuous coating gives customer a very stable quality and high output.
High energy to deposite the atom on the glass, the coating film stick on the glass firmly.
Many kinds of metal could be used for the coating material, aluminium, titanium, chrome, stainless steel, copper, silver... Such makes a more colorful mirror than ever.
The coating process is continuous working, the painting machine could be connected online.
With the aluminium sputtering process, we can get a high reflectivity than evaporation process up to 83%.
Coated with hard coating, chrome and some semi-conductive film, the Front Surface Reflective Mirror is available which give us a more clear view.
We can use the metal or oxide to be the protective coating instead of the back painting, make the real None-lead mirror.
Aluminum Mirrors
High reflectivity, high deposit density, different material like Chrome, Stainless steel or Titanium could be coated as the protective layer. With advanced sputtering technology, the mirror producing industry has entered the new generation of less pollution and none-lead age.
