噴粉是指用電暈放電使粉末類涂料黏附于工件上的一種涂裝工藝，是現(xiàn)代高速多色膠印工藝中必不可少的工序。下面為大家介紹一下噴粉的相關(guān)知識(shí)。

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.

噴漆目的是什么？ 

What is the purpose of painting?

　　首先是防護(hù)性，以延長(zhǎng)工件壽命，其次是裝飾性，達(dá)到美觀宜人。再次是特殊用途，以達(dá)到特殊性能。如：隔音、絕熱、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.

　　根據(jù)涂裝的目的和要求的不同，涂裝的涂層有好幾層組成，其中包括底漆、膩?zhàn)印⒚嫫嵴止獾取?/p>

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

　　底層漆：是與被涂工件機(jī)體直接接觸的最下層涂層，底漆層的作用是強(qiáng)化涂層與機(jī)體之間的附著力，強(qiáng)化涂層的防護(hù)性能。黑色金屬在除裝之前應(yīng)磷化，有色金屬涂裝之前應(yīng)氧化處理。

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.

　　膩?zhàn)訉樱簩?duì)于粗糙不平的機(jī)體，使用膩?zhàn)訉佑泻芏嗳秉c(diǎn)，諸如施工麻煩、降低涂層與機(jī)體的結(jié)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.

　　面漆層的主要目的是增加產(chǎn)品的光澤，用于涂層的最外層。

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.
