防静电措施可能也是大多数人想问的问题,尤其是在安装电缆桥架的过程中,往往会出现一些小问题。如何采取措施避免工作的顺利完成?今天
济南电缆桥架厂家就来教教大家。
Anti static measures may also be the question most people want to ask, especially in the process of installing cable tray, some small problems often occur. How to take measures to avoid the smooth completion of the work? Today, Jinan cable bridge manufacturer will teach you.
1.预处理
1. Pretreatment
意图:去除工件表面的油污、灰尘、铁锈,在工件表面形成一层耐腐蚀的“磷化层”,可以增加喷涂层的附着力。
Intention: remove the oil stain, dust and rust on the surface of the workpiece, and form a corrosion resistant "phosphating layer" on the surface of the workpiece, which can increase the adhesion of the spraying layer.
主要工艺流程:脱脂、除锈、磷化、钝化。经过前处理后,工件表面无油、无锈、无灰尘,在原有银白色光泽的表面上形成均匀粗糙的灰色磷化膜,可防锈,增加喷涂层的附着力。
Main process flow: degreasing, rust removal, phosphating and passivation. After pretreatment, the workpiece surface is free of oil, rust and dust. A uniform and rough gray phosphating film is formed on the original silver white shiny surface, which can prevent rust and increase the adhesion of the spraying layer.
2.静电喷涂
2. Electrostatic spraying
意图:将粉末涂料均匀喷涂在工件表面,尤其是电缆桥架(包括单纯发生静电屏蔽的位置),大概使用高性能静电喷塑机完成喷涂。
Intention: Spray the powder coating evenly on the surface of the workpiece, especially on the cable tray (including the position where electrostatic shielding occurs only), and probably use a high-performance electrostatic spraying machine to complete the spraying.
工艺:应用静电吸附原理,在工件表面均匀喷涂一层粉末涂料;落下的粉末由回收系统回收,过筛后可重复使用。
Process: Apply electrostatic adsorption principle to evenly spray a layer of powder coating on the surface of the workpiece; The fallen powder is recovered by the recovery system and can be reused after sieving.
3.高温固化
3. High temperature curing
目的:将电缆桥架表面的粉末涂料加热到规定的温度并保温相应的时间,使其熔化、流平、固化,进而得到工件所需的表面。
Purpose: Heat the powder coating on the surface of the cable tray to the specified temperature and keep it warm for a corresponding time, so that it can be melted, leveled and solidified, and then obtain the required surface of the workpiece.
工艺:将喷涂后的工件推入固化炉,加热预定温度(一般为185度),保温相应时间(15分钟);开炉,取出,冷却,即得产品。
Process: push the sprayed workpiece into the curing furnace, heat the predetermined temperature (generally 185 ℃), and keep the temperature for a corresponding time (15 minutes); Open the furnace, take it out and cool it to get the product.
提示:加热及控制系统(包括电加热、燃油、燃气、燃煤等多种加热方式)+保温箱=固化炉。
Prompt: heating and control system (including electric heating, fuel oil, gas, coal and other heating methods)+incubator=curing furnace.
4.装饰和处理
4. Decoration and treatment
目的:使静电喷涂后的工件达到特殊的外观。
Purpose: To make the workpiece after electrostatic spraying reach a special appearance.
