1. Pretreatment:

目的：除掉工件表面的油污、灰塵、銹跡，并在工件表面生成一層抗腐蝕且能夠增加噴涂涂層附著力的“磷化層”。

Objective: to remove the oil, dust and rust on the surface of the workpiece, and form a "phosphating layer" on the surface of the workpiece, which is anti-corrosion and can increase the adhesion of the spray coating.

主要工藝步驟：除油、除銹、磷化、鈍化。工件經(jīng)前處理后不但表面沒有油、銹、塵，而且原來銀白色有光澤的表面上生成一層均勻而粗糙的不容易生銹的灰色磷化膜，既能防銹又能增加噴塑層的附著力

Main process steps: degreasing, derusting, phosphating and passivation. After pretreatment, there is no oil, rust and dust on the surface of the workpiece, and a uniform and rough gray phosphating film which is not easy to rust is formed on the original silver white glossy surface, which can not only prevent rust, but also increase the adhesion of the plastic spraying layer

2、靜電噴涂

2. Electrostatic spraying

目的：將粉末涂料均勻地噴涂到工件的表面上，特殊工件（包含容易產(chǎn)生靜電屏蔽的位置）應該采用高性能的靜電噴塑機來完成噴涂。

Objective: the powder coating is evenly sprayed on the surface of the workpiece, and the special workpiece (including the position easy to produce electrostatic shielding) should be sprayed by high-performance electrostatic spraying machine.

工藝步驟：

Process steps:

利用靜電吸附原理，在工件的表面均勻的噴上一層粉末涂料；

Using the principle of electrostatic adsorption, spray a layer of powder coating evenly on the surface of the workpiece;

落下的粉末通過回收系統(tǒng)回收，過篩后可以再用

The fallen powder is recycled by the recycling system and can be reused after screening

3、高溫固化

3. High temperature curing

目的：將工件表面的粉末涂料加熱到規(guī)定的溫度并保溫相應的時間，使之熔化、流平、固化，從而得到我們想要的工件表面效果。

Objective: to heat the powder coating on the surface of the workpiece to the specified temperature and keep it warm for the corresponding time to make it melt, level and solidify, so as to obtain the desired surface effect of the workpiece.

工藝步驟：將噴涂好的工件推入固化爐，加熱到預定的溫度（一般185度），并保溫相應的時間（15分鐘）；開爐取出冷卻即得到成品。

Process steps: push the sprayed workpiece into the curing furnace, heat it to the predetermined temperature (generally 185 ℃), and keep it for 15 minutes; The finished product can be obtained by heating and cooling.

提示：加熱及控制系統(tǒng)（包括電加熱、燃油、燃氣、燃煤等各種加熱方式）+保溫箱體=固化爐。

Tips: heating and control system (including electric heating, fuel oil, gas, coal and other heating methods) + insulation box = curing furnace.

4、裝飾處理：

4. Decoration treatment:

目的：使經(jīng)過靜電噴涂后的工件達到某一種特殊的外觀效果如：各種木紋、花紋、增光等。

Objective: to make the workpiece after electrostatic spraying achieve a special appearance effect, such as various wood grain, pattern, gloss, etc.

工藝步驟：罩光；轉印等處理工藝
