How to activate the surface of silicone products, in many industrial and daily supplies, silicone products are widely used because of their superior temperature resistance, anti-aging and good elasticity. However, the inertia of the silica gel surface makes it necessary to improve its performance by activation treatment in some application scenarios.
1. Understand the surface activation of silicone products
The surface activation of silica gel products is mainly to change the chemical properties of the silica gel surface by chemical or physical methods, so as to enhance its binding force with other substances and increase the functionality of its surface. The activated silica gel surface can be better coated, bonded, printing and other subsequent processing.
2. Common surface activation treatment methods of silicone products
Chemical activation treatment: The use of specific chemical agents to treat the surface of silicone, such as the use of silane coupling agents, surfactants, etc. This method can effectively change the chemical structure of silica gel surface and improve its surface energy.
Plasma treatment: The surface of silica gel is activated by plasma technology, and functional groups such as nitrogen and oxygen are introduced to improve the surface activity of silica gel.
Irradiation treatment: The use of ultraviolet light, electron beam and other irradiation sources to treat the surface of silica gel, trigger chemical reactions, and change the surface properties.
Coating treatment: The surface of the silica gel is coated with a layer of coating with a specific function, such as conductive coating, anti-stick coating, etc.
3. The effect of activation treatment
Improve bonding performance: The activated silicone surface can enhance the bonding force with adhesives, coatings, etc., and improve bonding strength.
Enhanced functionality: The activated silica gel surface can show different functions according to needs, such as electrical conductivity, thermal conductivity, wear resistance and so on.
Improve printing quality: After activation of the silicone surface, the adhesion of the ink and the printing effect will be improved.
4. Precautions for activation processing
Choose the appropriate activation method: according to the application scenario and performance requirements of silicone products, choose the most appropriate activation treatment method.
Control the degree of activation: the degree of activation should be moderate, and excessive activation may lead to a decline in the surface performance of the silica gel.
Protection after treatment: the activated silica gel surface should avoid contamination and damage, and carry out subsequent processing as soon as possible.
