In many industrial fields, PET nickel plated film has been widely used due to its unique performance combination, such as good flexibility, high conductivity, and excellent chemical resistance. However, during use, PET nickel plated film is prone to mechanical damage, which not only affects its appearance but may also lead to a decrease in functionality. Advanced Institute (Shenzhen) Technology Co., Ltd. is researching how to avoid
PET nickel plated filmA series of achievements have been made in terms of mechanical damage.
1、 Understand the structure and characteristics of PET nickel plating film
PET nickel plated film is a layer of nickel metal deposited on the surface of polyester (PET) film through a specific nickel plating process. PET film itself has high tensile strength and flexibility, but the nickel plating layer is relatively thin and has high hardness, which makes it more prone to damage when subjected to external forces. For example, when scratched by sharp objects, the nickel plating layer may be scratched, and in severe cases, it may even penetrate the nickel plating layer, damaging the PET substrate and affecting the performance of the entire film material.
Advanced Institute (Shenzhen) Technology Co., LtdResearchers have conducted in-depth studies on the microstructure of PET nickel plated films using electron microscopy and other methods, identifying their weak links under different stress conditions.
2、 Common types and causes of mechanical damage analysis
- Scratch damage
During the transportation and processing, if the PET nickel plating film slides relative to the surface of other objects and there are sharp protrusions on the contact surface, it is highly susceptible to scratching and damage. For example, during the process of unwinding and unwinding the roll material, if there are foreign objects adhering to the surface of the equipment guide roller, they will leave marks on the surface of the film material. Research by the Advanced Institute has shown that scratch damage not only damages the appearance of nickel plating films, but also reduces their corrosion resistance, as scratches are more prone to electrochemical corrosion.
- tensile damage
When the PET nickel plating film is subjected to excessive stretching, the nickel plating layer may experience cracking, peeling, and other phenomena. This usually occurs when the film material is stretched or the tension control is improper during high-speed winding. Through simulating different tensile conditions, the Advanced Institute found that when the nickel plating film exceeds its ultimate tensile stress, the bonding force between the nickel plating layer and the PET substrate will be damaged, resulting in damage to the nickel plating layer.
- impact damage
On the production line, if any foreign objects accidentally fall and hit
PET nickel plated filmDuring transportation, collisions with the membrane material or other materials may cause impact damage. The impact will generate high stress locally, causing defects such as pits and cracks in the nickel plating film. The experimental data from the Advanced Institute shows that even small impact energies may have a significant impact on the performance of nickel plating films, especially on their electrical properties.
3、 Measures to avoid mechanical damage
- Optimize the handling and storage methods
- When handling PET nickel plated film, suitable handling tools should be used, such as soft rubber gloves or specialized vacuum suction cups, to avoid direct contact with the film surface with sharp tools. The advanced institute suggests placing the membrane material on customized trays or scrolls to ensure that it remains flat during transportation and reduce damage caused by shaking and friction.
- The storage environment is also crucial. Membrane materials should be stored in a dry and clean environment, avoiding contact with corrosive substances. At the same time, the stacking height of the rolls should not be too high to prevent the bottom membrane material from being deformed due to excessive pressure. Research by the Advanced Institute has found that reasonable storage conditions can effectively reduce the probability of mechanical damage to membrane materials during storage.
- Improve processing equipment and technology
- Regular maintenance and cleaning of processing equipment are key to avoiding scratching and damage. The Advanced Institute suggests using materials with high hardness and low roughness at the parts of the equipment such as guide rollers and pressure rollers that come into contact with the film material, and regularly checking their surfaces for wear or foreign object adhesion. For example, installing an automatic cleaning device on the winding equipment to promptly remove dust and impurities from the surface of the guide rollers.
- Accurate control of tension is the core to prevent tensile damage during the stretching process. The advanced institute has developed an intelligent tension control system based on sensors, which can monitor the tension changes of the film material in real time and automatically adjust the winding speed and stretching force, ensuring that the film material is always within a safe stress range during the stretching process.
- To prevent potential impact damage, protective devices such as buffer pads and guardrails should be installed around the equipment to prevent foreign objects from falling and hitting the membrane material. At the same time, in the transportation link, the membrane materials shall be properly packaged and protected with buffer materials such as foam and sponge.
- Personnel training and quality monitoring
- Provide professional training to operators to fully understandPET nickel plated filmMastering the correct operating methods based on the characteristics and easily damaged factors. Advanced Institute regularly organizes relevant training courses to teach operators skills and precautions to avoid mechanical damage.
- Establish a comprehensive quality monitoring system and set up multiple testing points on the production line to monitor the appearance, thickness, electrical properties, and other aspects of the film material in real-time. Once signs of mechanical damage are detected, adjust production processes or equipment parameters in a timely manner to avoid further expansion of the damage.
Through the comprehensive application of the above measures, combined with the in-depth research of Advanced Institute (Shenzhen) Technology Co., Ltd. in the field of materials science and engineering, it is possible to effectively avoid mechanical damage to PET nickel plating film during use, ensure the stability and reliability of its performance, and provide strong support for the high-quality development of related industries.
