In the process of producing cable tray, what is the electrostatic spraying process? Have you known about it? Now let's take a look at the relevant content of the simple description of the electrostatic spray molding process of the cable tray.
Cable tray spray technology is also known as electrostatic powder spraying. It uses electrostatic generator to make the plastic powder charged, adsorb on the surface of iron plate, and then after baking at 180 ~ 220 ℃ by high temperature fan, the powder melts and adheres to the metal surface. Spray products are mostly used for indoor boxes, and the paint film shows flat or matte effect. Spray powder mainly includes acrylic powder, polyester powder, etc.
Using the principle of electrostatic adsorption, spray a layer of powder coating evenly on the surface of the workpiece; The fallen powder is recovered by the recovery system and can be reused after screening. The powder coating on the surface of the workpiece is heated to the specified temperature and kept for the corresponding time to melt, level and solidify, so as to obtain the desired surface effect of the workpiece. Make the workpiece after electrostatic spraying achieve a special appearance effect, such as: all kinds of wood grain, pattern, gloss, etc.
