The color of the upper and lower plates of vacuum coating is not right, and the color of the two ends of a plate is different. In addition, what is the color blackening? The engineer from Rich Special Materials Co., Ltd, Mr Mu Jiangang, explains the reasons.
Blackening is caused by residual air in the furnace and low vacuum value. The color difference may be due to the difference between the position of the target and the position of the substrate.
Why do you know about the application of vacuum coating in life?
1. Applications in the field of optical film: antireflection film, high reflection film, cut-off filter, anti-counterfeiting film, etc.
2. Application in building glass: solar control film, low radiation glass, anti fog and anti dew and self-cleaning glass, etc.
3. Application in protective coating: blade of aircraft engine, automobile steel plate, heat sink, etc.
4. Application in hard coatings: cutting tools, molds and wear-resistant and corrosion-resistant parts.
5. Applications in the field of solar energy utilization: solar collector tube, solar cell, etc.
6. Application in integrated circuit manufacturing: thin film resistor, thin film capacitor, thin film temperature sensor, etc.
7. Applications in the field of information storage: magnetic information storage, magneto-optical information storage, etc.
8. Applications in the field of information display: LCD screen, plasma screen, etc.
9. Application in decorative accessories: coating of mobile phone case, watch case, glasses frame, hardware, trinkets, etc.
