静电喷塑工艺原理：

The principle of electrostatic spray technology:

用静电喷粉设备（静电喷塑机）把粉末涂料喷涂到工件的表面，在静电作用下，粉末会均匀的吸附于工件表面，形成粉状的涂层；粉状涂层经过高温烘烤流平固化，变成效果各异（粉末涂料的不同种类效果）的最终涂层；喷涂效果在机械强度、附着力、耐腐蚀、耐老化等方面优于喷漆工艺，塑料颗粒就会融化成一层致密的保护层牢牢附着在工件表面。成本也在同效果的喷漆之下。

The powder coating is sprayed onto the surface of the workpiece by electrostatic spraying machine (electrostatic spray machine). In electrostatic action, the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; the powder coating is solidified through a high temperature baking flow and becomes the final coating of different effects (different kinds of powder coatings). The effect is better than the spray painting process in mechanical strength, adhesion, corrosion resistance, aging resistance and so on. The plastic particles will melt into a dense layer of protection firmly attached to the surface of the workpiece. The cost is also under the effect of spray paint.

静电喷塑其工艺流程是前处理（除油、除锈、磷化）；静电喷涂；高温固化（参照塑粉要求温度，一般为160~210度）； 出炉冷却。

The process of electrostatic spray is pretreated (removing oil, removing rust and phosphating); electrostatic spraying; high temperature curing (referring to the temperature of plastic powder for 160~210); cooling.

静电喷塑传统的喷漆工艺的优点：

The advantages of traditional spray painting by electrostatic spray:

静电喷塑工艺与传统的喷漆工艺相比较，具有的显著优势，不需稀料，施工对环境无污染，对人体无毒害；涂层外观质量优异，附着力及机械强度强；喷涂施工固化时间短；涂层耐腐耐磨能力高出很多；不需底漆；施工简便，对工人技术要求低；成本低于喷漆工艺；有些施工场合已经明确提出必须使用静电喷塑工艺处理；静电喷粉喷涂过程中不会出现喷漆工艺中常见的流淌现象。 静电喷塑工艺流程：

Compared with the traditional spray painting technology, the electrostatic spray technology has remarkable advantages, without the need of thin material, no pollution to the environment, no poison to the human body, excellent appearance quality of the coating, strong adhesion and mechanical strength, short curing time of the coating and high resistance to corrosion and wear resistance of the coating; no primer is needed; the construction is simple and easy. The technical requirements of the workers are low; the cost is lower than the spray painting process; some construction occasions have clearly proposed that the electrostatic spraying process must be used; the common phenomenon in the spray painting process will not occur during the electrostatic spraying process. Electrostatic spray process flow:

1、前处理：除掉工件表面的油污、灰尘、锈迹，并在工件表面生成一层抗腐蚀且能够增加喷涂涂层附着力的“磷化层”。

1. Pretreatment: remove the oil, dust and rust on the surface of the workpiece, and create a layer of "phosphating layer" on the surface of the workpiece to resist corrosion and increase the adhesion of the coating.

工艺步骤：除油、除锈、磷化、钝化。工件经前处理后不但表面没有油、锈、尘，而且原来银白色有光泽的表面上生成一层均匀而粗糙的不容易生锈的灰色磷化膜，既能防锈又能增加喷塑层的附着力

Process steps: degreasing, rust removing, phosphating and passivation. The workpiece is not only surface without oil, rust, dust, but also on the original silvery white surface to produce a uniform and coarse, rough, rusty gray phosphating film, which can not only prevent rust but also increase the adhesion of the plastic layer.

2、静电喷涂：将粉末涂料均匀地喷涂到工件的表面上，特殊工件（包含容易产生静电屏蔽的位置）应该采用高性能的静电喷塑机来完成喷涂。

2, electrostatic spraying: powder coating is evenly sprayed to the surface of the workpiece, special work pieces (including easy to produce electrostatic shielding position) should be high performance electrostatic spray machine to complete the spray.

工艺步骤： 利用静电吸附原理，在工件的表面均匀的喷上一层粉末涂料； 落下的粉末通过回收系统回收，过筛后可以再用。

Process steps: using the principle of electrostatic adsorption, a layer of powder coating is evenly sprayed on the surface of the workpiece; the falling powder is recycled through the recovery system and can be reused after screening.

3、高温固化：将工件表面的粉末涂料加热到规定的温度并保温相应的时间，使之熔化、流平、固化，从而得到我们想要的工件表面效果。

3, high temperature curing: heating the powder coating on the surface of the workpiece to the specified temperature and holding the corresponding time, so that it is melted, leveled and solidified so as to get the surface effect of the workpiece we want.

工艺步骤： 将喷涂好的工件推入固化炉，加热到预定的温度（一般185度），并保温相应的时间（15分钟）；开炉取出冷却即得到成品。 提示：加热及控制系统（包括电加热、燃油、燃气、燃煤等各种加热方式） + 保温箱体=固化炉。

Process steps: push the sprayed workpiece into the curing furnace, heat it to the predetermined temperature (generally 185 degrees), and heat the corresponding time (15 minutes); take out the oven and get the finished product. Tip: heating and control system (including electric heating, fuel, gas, coal and other heating methods) + insulation box = curing oven.

4、装饰处理：使经过静电喷涂 后的工件达到某一种特殊的外观效果如：各种木纹、花纹、增光等。

4, decorative treatment: make the workpiece after electrostatic spraying to achieve a special appearance effect, such as: all kinds of wood grain, pattern, light and so on.
