Advanced Academy of Technology PET silver -plated reflective membrane is a common optical material, which has the characteristics of high reflection and high transmission. It is widely used in the fields of optical devices, solar cells, and LED display.

1. Preparation of PET silver-plated reflective membrane: PET silver-plated reflective membrane is made of silver film to 50-100um polyester film (PET). The silver -plated process mainly includes methods such as vacuum evaporation and silver -plated, magnetic sputtering silver plating and electrolytic silver. Among them, vacuum evaporation silver plating is a commonly used process. By putting the silver source into the vacuum coating machine, heating the silver source to sublute it and deposit it on the PET surface.

2. The characteristics of PET silver -plated reflection membrane: PET silver -plated reflex membrane has the characteristics of high reflection rate and high radiation rate. Within visible light range, the reflectivity of PET silver-plated reflectives can reach more than 80-97%, and the transmission rate is about 70%. In addition, the PET material itself has good flexibility and weather resistance, which can effectively protect the silver film from environmental.

3. Application of PET silver -plated reflective membrane: PET silver -plated reflective membranes are widely used in optical devices, solar cells, LED display and other fields. In an optical device, PET silver -plated reflective membrane can be used in optical lenses, reflectors, reflectors and other components to improve the reflectance and transmission of optical systems. In the field of solar cells, PET silver -plated reflectives can be used as a reflex mirror of the solar absorption layer to improve the photoelectric conversion efficiency of solar cells. In the LED display, PET silver -plated reflective membrane can be used to improve the light output efficiency of the LED chip and improve the brightness and contrast of the display.

4. The advantages and precautions of PET silver -plated reflective membrane: PET silver -plated reflex membranes have the advantages of simplicity, low cost, easy processing and good optical properties. However, silver -plated film is easily affected by factors such as oxidation, humidity, and mechanical damage. Therefore, it is necessary to pay attention to preventing the membrane layer from being damaged during use. In addition, parameters such as PET silver -plated reflective membrane coating, silver film uniformity, and adhesion are also an important indicator that affects its quality. It is necessary to strictly control the process conditions in the preparation process.

In short, PET silver -plated reflexes are a high -performance material in the fields of optical devices, solar cells, and LED display screens. By controlling the preparation process and optimizing the performance of the membrane layer, the PET silver -plated reflex membrane can be used in optical science More applications in the field of electronics.
