The rapid development of modern manufacturing industry has led to the application of coating technology in many products that appear around us unconsciously. So what Zhenhua is talking about today is a common coating technology——Vacuum magnetron sputtering coatingFor example, the glass on car windows and home windows is usedVacuum magnetron sputtering coatingTechnology is used for coating to achieve cooling and radiation reduction effects that other ordinary glasses do not possess.

Compared to evaporation coating,Vacuum magnetron sputtering coatingIf the film is more uniform, the thickness of the film deposited by vacuum evaporation coating is generally thinner at the center position.

Therefore, due to our inability to control the thickness of the film layer in vacuum evaporation coatingVacuum magnetron sputtering coatingDuring the process, the thickness of the coating can be controlled by controlling the length of time, so vapor deposition vacuum coating is not suitable for large-scale production in enterprises. On the contrarySputtering coating has advantages in this regard.

Compared to evaporation coating,Vacuum magnetron sputtering coatingIn addition to the advantages of uniform film thickness and controllable flexibility, there are also these characteristics:

1. The purity of the film layer deposited by magnetron sputtering is high, therefore it has good density;

2. The membrane material is flexible, and the film can be composed of most materials, including common alloys, compounds, etc;

3. The deposition rate of sputtering coating is relatively low, and the overall equipment is relatively complex;

4. The adhesion and bonding between the vacuum sputtered film and the substrate are excellent.

Vacuum magnetron sputtering coatingThe glass coated by technology is mainly used for two purposes: architectural glass and automotive glass. Generally speaking, these dielectric films are mostly zinc oxide, tin dioxide, titanium dioxide, silicon dioxide, etc. that can be plated on glass.

The use of building glass. We know that architectural glass needs to have the basic functions of transparency and insulation. But currently, many ordinary glasses need to pass through the vast majority of solar radiation energy. Of course, this is relatively friendly for lighting and absorbing and utilizing solar energy. However, for cyberspace and infrared radiation, although ordinary glass can prevent indoor heat from directly passing through the outdoors, the heat absorbed by the glass will cause secondary heat dissipation, which will inevitably result in significant losses. So many glasses on the market are becoming increasingly inadequate and cannot meet the requirements of the new era's development. And if adoptedVacuum SputteringThe equipment can compensate for the many shortcomings of glass by coating it with layers such as sunlight control film and low radiation film. Coating with sunlight control film can effectively meet the common demand for reducing indoor environmental temperature in low latitude areas; If coated with a low radiation film, it can improve the efficiency of indoor utilization of solar radiation energy in high latitude areas and block the outflow of indoor heat.

Vacuum magnetron sputtering coatingThe use of technology on car window glass. useVacuum magnetron sputtering coating equipmentTitanium dioxide can be coated on the car window glass, which can give the car window a self-cleaning effect and has a certain anti fog and anti dew effect.
