Surface damage issues that are prone to occur during the use of PET gold-plated reflective film

Brief introduction

PET gold-plated reflective film, as a high-performance material, is widely used in fields such as electronic products, building materials, optical instruments, solar cells, and furniture due to its excellent reflective properties and metallic luster. However, in actual use, PET gold-plated reflective films may be affected by various factors, leading to surface damage and subsequently affecting their performance and service life. This article will explorePET gold-plated reflective filmIntroduce the surface damage problems that are prone to occur during use, and present the research achievements and technical solutions of Advanced Institute (Shenzhen) Technology Co., Ltd. in this field.

2、 Structure and Properties of PET Gold Plated Reflective Film

PET gold-plated reflective film is a composite material composed of polyethylene terephthalate (PET) film and metal coating (mainly gold). PET film has excellent physical properties, chemical stability, and processability, while the metal coating endows it with metallic luster and excellent reflective properties. This material not only retains the lightweight, folding resistant, and transparent properties of PET film, but also possesses the conductivity and corrosion resistance of metals.

3、 Surface damage issues that are prone to occur during the use of PET gold-plated reflective film

Although PET gold-plated reflective film has excellent performance, there may still be some surface damage issues during actual use, mainly including the following types:

1. Scratches: During transportation, installation, and use,PET gold-plated reflective filmMay be scratched by hard objects, resulting in scratches on the surface. These scratches not only affect the appearance of the film, but may also reduce its reflective and conductive properties.

2. Oxidation: Although gold fittings have good corrosion resistance, in certain special environments such as high temperature, high humidity, or environments containing corrosive gases, the gold layer may undergo slight oxidation, resulting in surface color changes and decreased reflectivity.

3. Pollution: During use, the surface of PET gold-plated reflective film may be contaminated with dust, grease, fingerprints and other pollutants. These pollutants not only affect the transparency and reflection performance of the membrane, but may also cause secondary damage during the cleaning process.

4. Warping: Due to the different thermal expansion coefficients of PET film and metal coating, PET gold-plated reflective film may experience warping in environments with significant temperature changes. This kind of warping not only affects the flatness of the film, but may also lead to local stress concentration of the film, increasing the risk of surface damage.

5. Detachment: In some cases, such as uneven film thickness, insufficient coating adhesion, or improper use, the metal coating of PET gold-plated reflective film may experience detachment. This detachment not only affects the reflective and conductive properties of the film, but may also cause damage to the overall structure of the film.

4、 Advanced Institute (Shenzhen) Technology Co., Ltd.'s technical solutions

In order to address the potential surface damage issues that may occur during the use of PET gold-plated reflective films,Advanced Institute (Shenzhen) Technology Co., LtdWith a strong foundation in materials science and advanced production equipment, a series of technical solutions have been developed:

1. Optimize coating process: By optimizing vacuum coating or chemical coating technology, ensure that the metal layer adheres uniformly and firmly to the surface of PET film, improve the adhesion and wear resistance of the film, and reduce the occurrence of scratches and peeling.

2. Enhance corrosion resistance: By using special surface treatment techniques, the oxidation resistance of the gold layer is improved, allowing it to maintain good performance even in high temperature, high humidity, or environments containing corrosive gases.

3. Anti pollution coating: Apply a layer of anti pollution coating on the surface of PET gold-plated reflective film, effectively preventing the adhesion of pollutants such as dust, oil, fingerprints, etc., and maintaining the transparency and reflective performance of the film.

4. Thermal stability design: By adjusting the thickness ratio of PET film and metal coating, optimizing the matching of thermal expansion coefficient of the film, reducing the warping phenomenon caused by temperature changes, and improving the flatness and stability of the film.

5. Quality control and testing: Establish a strict quality control system, from raw material screening and film pretreatment to vacuum coating and quality inspection, striving for excellence in every aspect to ensure that every PET gold-plated reflective film can meet or even exceed industry standards.
