How Is The Surface Coating Of The Filing Cabinet Done?
Apr 13, 2022
The color of the surface of the filing cabinet is not paint, but electrostatic spraying.
1. Basic principles.
A high-voltage corona discharge electric field is formed between the filing cabinet and the workpiece. When the powder particles are ejected from the nozzle of the spray gun and pass through the discharge area, a large number of electrons are collected and turned into negatively charged particles, which are attracted to the workpiece under the action of electrostatic attraction. When the powder adheres to a certain thickness, the effect of "same-sex repulsion" will occur, and the powder can no longer be adsorbed, so that the thickness of the powder layer in each part is uniform. Then, after heating, baking and curing, the powder layer is flattened into a uniform film.
2. File cabinet powder electrostatic spraying process.
The typical process flow of powder electrostatic spraying is: upper part - degreasing - cleaning - rust removal - cleaning - phosphating - cleaning - passivation - powder electrostatic spraying - curing - cooling - lower part.
1. The practicality of the filing cabinet:
In order to ensure the practicability of the filing cabinet, the space in the filing cabinet must be reserved first. After all, the practicality of the file cabinet is mainly reflected in the storage function of the file cabinet. The more documents it can store, the more powerful it is. In addition, the file cabinet needs to have a certain degree of privacy to ensure that important documents will not be lost. Therefore, most companies will choose steel filing cabinets or iron filing cabinets, which has a great advantage, that is, high fire resistance, strong sealing effect, certain moisture absorption effect, and relatively large space.
2. File cabinet appreciation:
Ornamental is mainly reflected in color, style, size and so on. , and the material is actually an important part of viewing. But in order to ensure its practicality, the material has basically been determined to be steel or iron filing cabinets. Then it's down to color, style and size.
