When the cable tray wiring adopts steel pipe wiring, the steel pipe shall be left on the floor, and fireproof blocking material shall be added after wiring.

一、济南电缆桥架静电喷塑工艺

1、 Electrostatic plastic spraying process of Jinan cable bridge

1.目的：去除工件表面的油污、灰尘、锈迹，并在工件表面形成一层抗腐蚀的“磷化层”，使喷涂涂层具有附着力。

1. Purpose: remove oil, dust and rust on the surface of the workpiece, and form a corrosion-resistant "phosphating layer" on the surface of the workpiece to make the sprayed coating have adhesion.

2.过程：除油、除锈、磷化、钝化。经前处理后不仅表面无油、锈迹、尘埃，而且表面原本银白而有光泽的表面也会产生均匀而粗糙的不简单锈斑灰磷化膜，既防锈又能增加喷塑层的附着力

2. Process: degreasing, derusting, phosphating and passivation. After pretreatment, not only the surface is free of oil, rust and dust, but also the original silver white and shiny surface will produce uniform and rough non simple rust spot gray phosphating film, which can not only prevent rust, but also increase the adhesion of plastic spraying layer

二、静电喷雾法

Two. Electrostatic spray method

1.目的：将粉末涂料均匀地喷涂在工件表面，特殊工件(包括简单静电屏蔽的方位角)，大概选用高性能静电喷塑机来完成喷涂。

1. Purpose: evenly spray the powder coating on the surface of the workpiece. For special workpieces (including the azimuth of simple electrostatic shielding), high-performance electrostatic spraying machine is probably selected to complete the spraying.

2.工艺：应用静电吸附原理，在工件表面均匀地喷上一层粉末涂料，落粉回收系统，过筛后再使用。

2. Process: apply the principle of electrostatic adsorption, evenly spray a layer of powder coating on the surface of the workpiece, drop the powder recovery system, and then use it after screening.

三、高温进行养护

3、 Curing at high temperature

1.目的：加热工件表面的粉末涂料规定温度，并相应进行保温一段时间，使之熔化、流平、固化，达到所需的工件表面功能。

1. Purpose: heat the powder coating on the workpiece surface to the specified temperature, and keep it warm for a period of time to melt, level and solidify it, so as to achieve the required function of the workpiece surface.

2.处理过程：将喷涂件置于固化炉内加热预定温度(通常为185度)，并在相应的时间(15分钟)进行保温;打开炉门，使产品冷却。

2. Treatment process: place the sprayed parts in the curing furnace, heat them to the predetermined temperature (usually 185 degrees), and keep them warm at the corresponding time (15 minutes); Open the furnace door to cool the product.

四、装修处置：

4、 Decoration disposal:

通过静电喷涂，使工件达到特定的外观效果，如：各种木纹、斑纹、长脸等。

Through electrostatic spraying, the workpiece can achieve specific appearance effects, such as various wood grain, speckle, long face, etc.
