Common surface treatments of plastic tableware include electroplating, fuel injection, printing, water transfer and other surface treatment processes. In life, we should paint plastic surface.
The purpose of spraying plastic tableware is to form a solid continuous coating on the surface to give full play to its decoration, protection and other special functions.
Whether the plastic has crystallinity has a great influence on the adhesion of the paint film, and the adhesion of the paint film with high crystallinity is poor, and the surface coating is relatively good when the crystallinity is low. In addition, the surface energy of plastics is usually low (such as nylon and PP), which is not conducive to the adhesion of the coating, and the adhesion between the substrate and the coating is poor.
The direct influence of adhesion difference is to paint the surface, but it can not achieve the ideal surface treatment effect.
The effective way to improve adhesion is to improve adhesion through pretreatment of substrate. Compared with electric fish and polishing, the common methods are corona, flame, sanding, adhesion promoter, etc.
In the treatment mode, a layer of enamel treatment agent adhesion promoter is sprayed between the base material and the coating. The process operation is simpler and the effect is more stable and controllable, so it is widely used in the coating industry.
The force test can also pass smoothly.
