喷粉是指用电晕放电使粉末类涂料黏附于工件上的一种涂装工艺，是现代高速多色胶印工艺中必不可少的工序。下面为大家介绍一下喷粉的相关知识。

Powder spraying refers to a coating process that uses corona discharge to make powder coatings adhere to workpieces. It is an essential process in modern high-speed multi-color offset printing technology. Below, we will introduce the relevant knowledge of powder spraying.

喷漆目的是什么？ 

What is the purpose of painting?

　　首先是防护性，以延长工件寿命，其次是装饰性，达到美观宜人。再次是特殊用途，以达到特殊性能。如：隔音、绝热、防火等。

Firstly, it is protective to extend the lifespan of the workpiece, and secondly, it is decorative to achieve aesthetic appeal. Once again, it is for special purposes to achieve special performance. For example: sound insulation, thermal insulation, fire prevention, etc.

　　根据涂装的目的和要求的不同，涂装的涂层有好几层组成，其中包括底漆、腻子、面漆罩光等。

According to the different purposes and requirements of painting, the coating consists of several layers, including primer, putty, topcoat finish, etc.

　　底层漆：是与被涂工件机体直接接触的最下层涂层，底漆层的作用是强化涂层与机体之间的附着力，强化涂层的防护性能。黑色金属在除装之前应磷化，有色金属涂装之前应氧化处理。

Undercoat: It is the lowest layer of coating that directly contacts the body of the workpiece to be coated. The function of the primer layer is to strengthen the adhesion between the coating and the body, and to enhance the protective performance of the coating. Black metals should be phosphated before removal, and non-ferrous metals should be oxidized before painting.

　　腻子层：对于粗糙不平的机体，使用腻子层有很多缺点，诸如施工麻烦、降低涂层与机体的结合力等。

Putty layer: For rough and uneven bodies, using a putty layer has many drawbacks, such as inconvenient construction and reduced adhesion between the coating and the body.

　　面漆层的主要目的是增加产品的光泽，用于涂层的最外层。

The main purpose of the topcoat layer is to increase the gloss of the product, which is used for the outermost layer of the coating.
