Nowadays, manufacturing in Vietnam are also using various methods to enhance surface adhesion, such as:
- Mechanical: Frictional rubbing
- Chemical: Etching and phosphating
- Physical: Heat, static electricity, magnetic fields, laser beams, …
However, these methods exhibit clear drawbacks. Chemical methods are costly, have low efficiency, and contribute to environmental pollution.
The benefits of plasma activation lie in its effectiveness in altering the surface tension of materials like plastics, metals, fabrics, glass, recyclable materials, and especially composites. Surface energy is the target that plasma systems aim to impact, and it is also the main cause of poor adhesion on various materials.
Benefits of Plasma Activation
1. Improved Adhesion and Bonding Performance
Surface activation by plasma increases the surface energy of materials, allowing adhesives to spread evenly and enhancing the bonding capabilities of various materials such as plastics, metals, fabrics, glass, and composites. Plasma activation also improves the efficiency of adhesive dispensing, ensuring secure component adhesion and enhancing the overall performance and durability of the final product.
2. Cost Savings and Environmental Friendliness
Plasma activation eliminates the need for solvents with high volatile organic compound (VOC) content, thereby safeguarding worker health, maintaining a safe working environment, and minimizing environmental pollution. Additionally, it helps reduce material waste and production costs.
3. Non-Destructive Treatment
Plasma activation efficiently treats surfaces without causing material corrosion or affecting the structure and properties of the materials. Instead of using corrosive chemicals, plasma activation generates energy waves from air combustion and applies them to the material surface. This ensures the integrity and quality of the final product.
4. Integration into Automated Production Systems
Plasma activation can be seamlessly integrated into automated production processes. It can be utilized within machinery systems and robots to automate surface treatment, minimizing human intervention, increasing productivity, and ensuring consistent product quality.
Thanks to these benefits of plasma activation is becoming a popular method to enhance surface properties and improve the performance of materials in various industries.
