What is the PTFE sticky problem
PTFE is a polymer material with excellent heat resistance, corrosion resistance and anti-stick properties, and is widely used in the manufacture of various corrosion-resistant, high-temperature and anti-stick coatings. The anti-stick performance of PTFE materials will also become a difficulty in its application, especially when the PTFE surface needs to be bonded to other materials.
The traditional way to solve the problem of difficult sticking
The traditional way to solve the problem of difficult adhesion of PTFE is to improve its adhesion through surface treatment. Common surface treatment methods include chemical treatment and physical oxidation. Although these methods can improve the surface adhesion of PTFE, they will also cause some damage to its excellent performance, and the treatment effect is not ideal.
The principle of PTFE plasma treatment
PTFE plasma treatment is a novel surface treatment method that improves the surface adhesion of PTFE materials by placing them in low-temperature plasma to chemically change their surface. The principle of this method is to use high-energy particles in plasma to activate the surface of PTFE, so that the surface of the surface undergoes a chemical reaction to form hydrophilic groups, so as to improve its surface adhesion.
Advantages of PTFE plasma treatment
1.It will not damage the excellent performance of PTFE material;
2.The treatment effect is stable, and will not fluctuate due to changes in processing time, temperature and other factors;
3.After treatment, the adhesion performance of PTFE surface is significantly improved, and a good bonding effect can be achieved.
Application of PTFE plasma treatment
PTFE plasma treatment can be widely used in the surface treatment of PTFE materials, including:
1.surface treatment of PTFE coatings;
2.Surface treatment of PTFE refractory mucous membranes;
3.Surface treatment of PTFE pipes, etc.
The procedure for the PTFE plasma treatment method
1.The PTFE material is placed in a plasma treatment chamber;
2.The plasma treatment chamber was opened, and the PTFE material was placed in the plasma for treatment;
3.After the treatment, the PTFE material is removed for bonding and other subsequent treatments.
Precautions for PTFE plasma treatment
1.The plasma in the treatment chamber needs to be replaced regularly to ensure the stability of the treatment effect;
2.The temperature, air pressure and other parameters in the treatment room need to be strictly controlled to ensure the consistency of the treatment effect;
3.The treated PTFE material needs to be processed in time to avoid the loss of treatment effect.
PTFE plasma treatment is a new type of surface treatment method, which can effectively solve the problem of PTFE difficult to stick without damaging its excellent performance. This method has the advantages of stable treatment effect and simple operation, and can be widely used in the surface treatment of PTFE materials.
