塑料餐具表面處理的方法!
來源:jwwylp.com 發(fā)布時(shí)間:2021-07-02 瀏覽次數(shù):122
塑料餐具表面的常見處理包括電鍍,燃油噴射,印刷,水轉(zhuǎn)印和其他表面處理工藝。在生活中,我們應(yīng)該涂塑料表面。
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.
噴涂塑料餐具的目的是在表面形成堅(jiān)固的連續(xù)涂層,以發(fā)揮其裝飾,保護(hù)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.
塑料是否具有結(jié)晶性對漆膜的粘附性有很大影響,并且高結(jié)晶度的漆膜的粘合性能差,并且當(dāng)結(jié)晶度低時(shí)表面層涂層相對較好。另外,塑料的表面能通常較低(如尼龍和PP),這不利于涂層的粘附,并且基材和涂層之間的粘合性差。
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.
粘合力差異的能直接影響是在表面涂上油漆,但不能達(dá)到理想的表面處理效果。
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實(shí)際生產(chǎn)是通過預(yù)處理基材來改善粘合性。與電魚和拋光相比,常用的方法是電暈,火焰,砂光,粘合促進(jìn)劑等。
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.
在處理方式下,在基材與涂料之間噴涂一層搪瓷處理劑粘合促進(jìn)劑,工藝操作更簡單,效果更穩(wěn)定可控,因此廣泛應(yīng)用于涂料工業(yè)。
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.
力等測試也可順利通過。
The force test can also pass smoothly.
