电缆桥架喷塑工艺也就是我们常讲的静电粉末喷涂,它是利用静电发生器使塑料粉末带电,吸附在铁板表面,然后经过高温风机180~220℃的烘烤,使粉末熔化黏附在金属表面。下面来济南桥架厂家讲讲桥架静电喷涂工艺流程。
The cable tray spraying process is also known as electrostatic powder spraying. It uses an electrostatic generator to make the plastic powder charged, adsorbed on the surface of the iron plate, and then baked at 180-220 ℃ by a high-temperature fan to make the powder melt and adhere to the metal surface. Next, let's talk about the electrostatic spraying process of bridge from Jinan Bridge manufacturer.
1、前处理:
1. Pretreatment:
意图:去除工件表面的油污、灰尘和锈迹,在工件表面形成一层既防腐蚀又能增加喷涂层附着力的“磷化层”。
Intention: remove the oil, dust and rust on the surface of the workpiece, and form a "phosphating layer" on the surface of the workpiece, which can not only prevent corrosion, but also increase the adhesion of the spraying layer.
主要工艺流程:脱脂、除锈、磷化、钝化。预处理后的工件不仅表面无油污、锈迹和灰尘,而且在原有银白色光泽的表面上形成一层均匀粗糙的不易生锈的灰色磷化膜,可起到防锈作用。并添加一个喷涂层。
Main process flow: degreasing, derusting, phosphating and passivation. The pretreated workpiece is not only free of oil, rust and dust on the surface, but also forms a layer of uniform and rough gray phosphating film that is not easy to rust on the original silver gloss surface, which can play a role in rust prevention. And a spray coating is added.
2、静电喷涂
2. Electrostatic spraying
用途:将粉末涂料均匀喷涂在工件表面,尤其是工件(包括容易产生静电屏蔽的位置)或使用高性能静电喷涂机完成喷涂。
Usage: evenly spray powder coating on the surface of workpieces, especially workpieces (including positions prone to electrostatic shielding) or finish spraying with high-performance electrostatic spraying machine.
技术流程:
Technical process:
利用静电吸附原理,在工件表面均匀喷涂一层粉末涂料;落下的粉末通过回收系统回收,筛分后可重复使用。
Using the principle of electrostatic adsorption, evenly spray a layer of powder coating on the surface of the workpiece; The fallen powder is recycled through the recycling system and can be reused after screening.

3、高温固化
3. High temperature curing
目的:将工件表面的粉末涂料加热到一定温度,并保持相应的时间使其熔化、流平、固化,从而获得工件所需的表面效果。
Objective: to heat the powder coating on the surface of the workpiece to a certain temperature and keep it for a corresponding time to melt, level and solidify, so as to obtain the surface effect required by the workpiece.
工艺流程:将喷涂好的工件推入固化炉,加热至预定温度(一般为185度),并保持相应的时间(15分钟);打开炉子,取出冷却即可得到产品。
Process flow: push the sprayed workpiece into the curing furnace, heat it to a predetermined temperature (generally 185 degrees), and keep it for a corresponding time (15 minutes); Turn on the stove, take out the cooler and get the product.
提示:加热及控制系统(包括电加热、燃油、燃气、煤等加热方式)保温箱=固化炉。
Prompt: heating and control system (including electric heating, oil, gas, coal and other heating methods) incubator = curing furnace.
4、装修与处置:
4. Decoration and disposal:
意图:使静电喷涂后的工件达到一定的特殊外观,如:各种木纹、条纹、长面等。
Intention: make the workpiece after electrostatic spraying achieve a certain special appearance, such as various wood grains, stripes, long surfaces, etc.
以上是电缆桥架表面采取的防静电措施,希望以上介绍可以帮助到你。另外电缆桥架本身没有强弱电之分,但对安装有一定要求。更为详细的内容就来我们网站http://www.sddlqj.cn咨询了解吧。
The above are the anti-static measures taken on the surface of the cable tray. I hope the above introduction can help you. In addition, there is no strong or weak current in the cable tray itself, but there are certain requirements for installation.
