How can PET silver plated reflective film avoid oxidation or discoloration of the silver layer at high temperatures?

PET silver plated reflective film has important applications in multiple fields due to its excellent reflective performance and good mechanical strength. However, in high-temperature environments, the silver layer is prone to oxidation, leading to a decrease in reflectivity and changes in physical properties. This article will explore how to effectively avoidPET silver plated reflective filmThe issue of oxidation or discoloration at high temperatures, with special mention of the technological advantages and product features of Advanced Institute (Shenzhen) Technology Co., Ltd. in this field.

1. Vacuum silver plating technology

The vacuum evaporation plating technology adopted by Advanced Institute (Shenzhen) Technology Co., Ltd. can effectively reduce oxidation and impurity introduction, ensuring high purity and density of the coating. By adjusting the evaporation rate and time, accurate control of thickness can be achieved, thereby improving the stability and antioxidant capacity of the silver layer.

2. Sputtering plating technology

Sputtering plating technology involves the sputtering of silver target atoms onto PET substrates under high-energy particle bombardment. By adjusting parameters such as the distance between the target material and the substrate, sputtering power, etc., customized thickness can be achieved to enhance the adhesion and oxidation resistance of the silver layer.

3. Ion plating technology

By combining the principles of vacuum evaporation and sputtering, ion beam is used to accelerate the deposition of silver atoms, and ion bombardment is used to enhance the binding force, achieving high-quality and high-precision silver plating process and effectively improving the oxidation resistance of the silver layer.

4. Special surface treatment technology

Advanced Institute (Shenzhen) Technology Co., LtdThe research platinum brand PET silver plated reflective film adopts special surface treatment technology and protective coating, which effectively reduces the chance of contact between the silver layer and corrosive substances in the external environment, thereby delaying the oxidation rate of the silver layer.

5. Preparation method of antioxidant PET silver film

A method for preparing antioxidant PET silver film, comprising using roll to roll sputtering to deposit Ag thin film on the surface of PET substrate, selecting Sn or Zn to use roll to roll sputtering coating on Ag thin film, forming Sn metal film layer or Zn metal film layer; Apply polyurethane waterproof coating on Sn metal film layer or Zn metal film layer, which solidifies upon contact with moisture in the air to form a polyurethane protective layer; Using a micro concave bonding continuous machine, a 50um thick polyester PET white film, polyester PET black film, or polyester PET aluminum plated film is attached to the polyurethane protective layer. This method effectively slows down the oxidation rate by adding a protective layer on the silver layer.

6. Avoid contact with chemical substances

To prevent oxidation of the silver layer, it should be avoided as much as possiblePET silver plated reflective filmIn contact with chemicals, such as cosmetics, perfume, detergent, etc., the composition of these chemicals will accelerate the oxidation process of silver.

7. Storage precautions

When PET silver plated reflective film is not used, it should be stored in a dry, dark place. A dedicated film box can be used or the film can be placed in a sealed bag to prevent moisture and light from oxidizing the silver layer in the air.

8. Coating protection

To further protect the silver layer, it can be coated for protection. Common coating materials include platinum, rhodium, nickel, etc. These coatings can effectively isolate the silver layer from contact with air and delay the oxidation process of the silver layer.

Through the above methods, it is possible to effectively avoid oxidation or discoloration of PET silver plated reflective films at high temperatures, ensuring their long-term stability and high performance. Advanced Institute (Shenzhen) Technology Co., Ltd. provides reliable solutions for the application of PET silver plated reflective films with its professional technology and products.
