Three steps of spray painting of dust skeleton
As the skeleton of bag filter, the quality of dust removal skeleton is self-evident. So how can we enhance the performance of the dust removal framework? Electrostatic spraying for dust removal frame is a good protection measure, which is much better than the ordinary zinc plating dust removal framework.
1. the dedusting skeleton of zinc plating is easily affected by environmental factors and corroded, thus directly reducing the life of bag filter and dusting cloth bag.
2. after spraying, the adhesion and mechanical strength will increase.
3. after spraying, the dust removal skeleton can endure higher temperatures.
4. because of spraying, the surface is more smooth, which is conducive to installation.
The principle of spraying dust removal framework: using corona discharge to adsorb powder coating on the workpiece. The process is that the powder coating is sent into the spray gun by the compressed air gas by the powder supply system and the high pressure produced by the high voltage electrostatic generator at the front of the spray gun. The dense charge is produced near it by the corona discharge. When the powder is ejected from the nozzle, it forms the charged coating particles. It is absorbed by the electrostatic force and is sucked to its polarity. On the contrary, as the powder increases and the charge accumulates, the more the charge accumulates. When a certain thickness is reached, the adsorption is not continued because of the electrostatic repulsion, so that the whole workpiece is coated with a certain thickness, then the powder is fused, leveled and solidified through high temperature, that is to form the hard surface of the workpiece. A hard coating.
In fact, it is necessary to pay attention to the removal of oil, rust and phosphating. Polyester powder is best used for spraying, and the temperature is controlled between 180-260 degrees Celsius. It should be cooled after curing at high temperature.
