塑料餐具表面处理的方法!
来源:www.sdynbz.com 发布时间:2021-07-02 浏览次数:122
塑料餐具表面的常见处理包括电镀,燃油喷射,印刷,水转印和其他表面处理工艺。在生活中,我们应该涂塑料表面。
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.
喷涂塑料餐具的目的是在表面形成坚固的连续涂层,以发挥其装饰,保护和其他特殊功能。
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.
塑料是否具有结晶性对漆膜的粘附性有很大影响,并且高结晶度的漆膜的粘合性能差,并且当结晶度低时表面层涂层相对较好。另外,塑料的表面能通常较低(如尼龙和PP),这不利于涂层的粘附,并且基材和涂层之间的粘合性差。
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.
粘合力差异的能直接影响是在表面涂上油漆,但不能达到理想的表面处理效果。
The direct influence of adhesion difference is to paint the surface, but it can not achieve the ideal surface treatment effect.

有效提高粘合力的方法涂料的实际生产是通过预处理基材来改善粘合性。与电鱼和抛光相比,常用的方法是电晕,火焰,砂光,粘合促进剂等。
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.
在处理方式下,在基材与涂料之间喷涂一层搪瓷处理剂粘合促进剂,工艺操作更简单,效果更稳定可控,因此广泛应用于涂料工业。
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.
力等测试也可顺利通过。
The force test can also pass smoothly.
