PVC what chemicals do you need for plastic surface treatment?
At present, the use of petroleum as raw materials of plastics, fibers, synthetic rubber and other synthetic organic polymer materials is increasing, and is still growing rapidly. But in actual use, people gradually found that this kind of material has many problems such as surface, low surface hardness and poor barrier property, difficult printing, difficult bonding, electrostatic, biocompatibility and poor surface, these problems not only seriously influence the performance of these products, but also greatly limits its application to further expand the market the.
The choice of surface treatment methods, because most of the plastic surface can be low, many processing methods, such as decoration, printing, spraying and so on, can not be directly applied, and the need for surface treatment first
Different processing methods are often required for different materials.
The commonly used techniques: solvent cleaning (skim), corona treatment, short wavelength ultraviolet radiation treatment, sandpaper treatment, sandblasting processing, plasma etching, chemical etching, heat treatment etc..
