Corrosion resistance guarantee technology for PET gold plating film in humid environment

In modern electronics, optics and other fields, PET gold plating film has been widely used due to its excellent conductivity and chemical corrosion resistance. However, the corrosive effect of humid environments on metal coatings cannot be ignored. To ensure the corrosion resistance of PET gold plating film in humid environments, a series of effective techniques and measures need to be taken. This article will combine the practical experience of Advanced Institute (Shenzhen) Technology Co., Ltd. to explore how to ensurePET gold-plated filmThe corrosion resistance performance.

1、 Fundamentals of Chemical Corrosion Resistance of PET Gold Plated Film

The chemical corrosion resistance of PET gold-plated film is mainly due to the chemical stability of the gold layer itself and the excellent properties of the PET substrate. Gold, as a precious metal, has high chemical stability and is not easily reacted with other chemicals. It can resist the erosion of various acids, bases, and organic solvents. PET substrate is a type of polyester plastic with excellent mechanical properties, heat resistance, and chemical resistance, capable of withstanding corrosion from various chemical substances.

2、 The influence of humid environment on PET gold plating film

Humidity has a significant impact on metal materials, including corrosion, crystallization, and deformation. When the humidity reaches a certain level, water droplets are easily formed on the metal surface, accelerating the oxidation and corrosion processes.PET gold-plated filmAlthough it has high chemical stability, the metal layer may still undergo oxidation and corrosion in long-term humid environments, which can affect its conductivity and overall performance.

3、 Technical measures to ensure the corrosion resistance of PET gold-plated film

1. Choosing the appropriate reducing agent: In the chemical reduction process, it is crucial to choose a reducing agent that can stably reduce gold ions without introducing accelerated oxidation impurities.Advanced Institute (Shenzhen) Technology Co., LtdWhen preparing PET gold plating film, the reaction temperature, pH value, and reaction time are strictly controlled to ensure that gold ions are uniformly and stably reduced to metal particles and deposited on the PET base film.

2. Coating protective paint:
   Coating a layer of transparent protective paint on the surface of the metal particle coating can effectively isolate air and moisture, preventing oxidation of the metal layer. The selection of protective paint should be based on its antioxidant properties, compatibility with PET base film and metal coating, and its impact on subsequent processing.

3. Add antioxidants:
   Adding appropriate antioxidants during the preparation process or post-treatment stage of the coating can inhibit the occurrence of oxidation reactions. The selection of antioxidants should consider their protective effect on metal coatings, compatibility with PET base films, and their impact on product performance.

4. Control storage and transportation conditions:
   To avoid prolonged exposure of PET gold-plated film to humid environments, desiccants or sealed packaging can be used to keep the environment dry. At the same time, PET gold-plated film should be avoided from prolonged exposure to sunlight and stored and transported in a cool and dark environment.

5. Regular testing and adjustment of processes:
   Regularly conduct oxidation performance testing on PET gold-plated film to evaluate changes in its antioxidant properties. According to the test results, adjust the preparation process and antioxidant measures in a timely manner to ensure stable product quality.

4、 Practice of Advanced Institute (Shenzhen) Technology Co., Ltd

Advanced Institute (Shenzhen) Technology Co., Ltd. strictly controls the quality of each step in the preparation process of PET gold plating film to ensure that each step meets the process requirements. The company adopts advanced electroplating technology and equipment, and obtains a uniform, dense, and strongly adhesive gold layer by precisely controlling electroplating parameters and plating solution composition. In addition, the company also pays attention to the testing and screening of raw materials and semi-finished products to ensure product quality.

In practical applications, Advanced Institute (Shenzhen) Technology Co., LtdPET gold-plated filmHas demonstrated excellent corrosion resistance, maintaining stable conductivity and overall performance even in humid environments. This is due to the company's strict control and continuous innovation in the preparation process.

5、 Conclusion

The guarantee of corrosion resistance of PET gold-plated film in humid environments is a systematic project that requires multiple aspects to be addressed. By selecting appropriate reducing agents, applying protective paint, adding antioxidants, controlling storage and transportation conditions, and regularly testing and adjusting processes, the corrosion resistance of PET gold plating films can be effectively improved. The practice of Advanced Institute (Shenzhen) Technology Co., Ltd. has shown that these measures are feasible and can ensure the stable performance of PET gold plating film in humid environments.
