Plasma surface treatment technology automotive plastic medical electronics industry application guide

Plasma surface treatment technology automotive plastic medical electronics industry application guide:
Plasma treatment is one of the effective treatment processes for cleaning, activating and coating the surface. It can be used to treat various materials, including plastic, metal, or glass. The plasma treatment machine cleans the surface and can remove the release agent and additives on the surface. The activation process can ensure the quality of the subsequent bonding process and coating process. For coating treatment, it can be further Improve the surface characteristics of the composite. Using this plasma technology, the surface pretreatment of materials can be efficiently performed according to specific process requirements.

1. Plasma treatment of surface modification of plastic and rubber materials
Through low-temperature plasma surface treatment, the surface of the material undergoes various physical and chemical changes, or is etched and rough, or forms a dense cross-linked layer, or introduces oxygen-containing polar groups to make the surface hydrophilic and adhesive. , Dyeability, biocompatibility and electrical properties were improved. Plasma performs surface treatment on silicone rubber. As a result, N2, Ar, O2, CH4-O2 and Ar-CH4-O2 plasma can all improve the hydrophilicity of silicone rubber. Among them, CH4-O2 and Ar-CH4-O2 are more effective. Good, and does not degrade over time.
Treating materials such as PE, PP, PVF2, LDPE with low-temperature plasma under suitable process conditions, the surface morphology of the material has changed significantly, and a variety of oxygen-containing groups have been introduced, which makes the surface change from non-polar and difficult to stick to It has a certain polarity, easy adhesion and hydrophilicity, which is conducive to bonding, coating and printing.
2. Plasma technology surface grafting treatment
Plasma graft polymerization is used to modify the surface of the material, and the graft layer is covalently bonded to the surface molecules to obtain an excellent and durable modification effect. In the United States, the polyester fiber was treated by glow discharge plasma and grafted with acrylic acid. After the modification, the water absorption of the fiber was greatly improved, and the antistatic performance was also improved.
