With the development trend of industrial lightweight, the application field of plastics has been continuously expanded. With the demand for material properties, plastic modification technology has also been continuously improved. However, in terms of plastic surface treatment, due to the differences between various plastic structures and components, the differences in surface properties are also obvious, so plastic surface treatment agents have emerged at the historic moment.

Influence of structure and components: Most of the surface of plastic materials show high crystallinity and low surface energy, and some of them are non-polar materials. In addition, in order to modify the effects of additives, the surface condition becomes more complicated. Spraying Or the substrate and paint or glue come off during the gluing process, such as polypropylene PP material. Metal substrates are mostly smooth or have an oxide layer. For example, stainless steel has a smooth surface, which makes it difficult to oil.

Impact of surface treatment methods: In recent years, many technical methods have been developed for the problems of plastic surface treatment. In the actual surface treatment process, corona, flame, solvent cleaning, ultraviolet, plasma and other methods have appeared relatively. More common. Compared with the surface treatment method, the automatic surface spraying, hand spraying and brushing of plastic surface treatment agents are more suitable for plastic surface treatment processes.

Selection of plastic surface treatment agent: Of course, the selection of plastic surface treatment agent is to choose the excellent adhesion and can have a high degree of agreement with the material. In addition to the plastic surface treatment agent itself, we need to know more about the material and the properties of the substrate, whether it is pure or modified, and whether or not miscellaneous materials have been added to facilitate the more accurate selection of the phase. Corresponding treatment agents, in general, the plastic surface adhesion treatment agents developed by 炅 盛 treatment agents are not selective for paints and have a wide range of applicability.

With the improvement of material surface spraying and adhesive quality requirements, more and more attention has been paid to improving the efficiency and reliability of coating production. New technical surface treatment technologies have been continuously developed and applied. Plastic surface treatment agents are materials and coatings. The development and change of the packaging process are widely used to improve the adhesion between the substrate and the paint and glue, and effectively solve the production yield and quality problems.
