Principles, advantages and disadvantages of electrostatic spray painting

Spraying is just a general term, and there are many specific spraying methods. In the past, most of my friends may have only had a certain understanding of manual spraying. However, with the continuous advancement of science, the shortcomings of this method have gradually been exposed. , now many construction workers have begun to change this method of operation. Currently, electrostatic spraying is mostly used for large-scale projects. So what is electrostatic spraying? What is the principle of electrostatic spraying? What are the advantages and disadvantages of electrostatic spraying? Let us continue reading with these questions.

1. Principle of electrostatic spraying

In electrostatic spraying, the object to be coated is the positive electrode and the paint atomization device is the negative electrode. The former is grounded and the latter is energized, thus forming two electrodes. Using the principle of same-sex repulsion and opposite-sex attraction, the paint is sprayed from the atomization device, and finally an even and strong film is formed. This is The principle of electrostatic spraying.

2. Advantages of electrostatic spraying

Advantage one

Compared with the original manual spraying, the biggest advantage of electrostatic spraying is its high construction efficiency. The original manual spraying is generally not suitable for large-area operations, but electrostatic spraying has no scruples about large-area operations, and construction personnel can completely install it. Multiple electrostatic spray guns can spray at the same time, which can effectively shorten the spraying time and improve the spraying efficiency.

Advantage 2

If it only saves spraying time, electrostatic spraying will not be widely praised. It also has a very significant advantage, that is, the adhesion of the paint film of electrostatic spraying is higher than that of manual spraying, and it can also improve the quality of the paint. Utilization rate ensures that the paint film is even and plump, and plays a good decorative role in the interior.

3. Disadvantages of electrostatic spraying

Disadvantage one

Of course, electrostatic spraying also has certain shortcomings. Although electrostatic spraying is very suitable for large-area construction, electrostatic spraying is often stumped by some workpieces with relatively complex shapes, which can cause uneven paint films and require manual repair. , causing more troublesome consequences.

Disadvantage 2

In addition to the imperfections above, electrostatic spraying requires a lot of investment and requires the purchase of a large amount of equipment. Construction workers should be particularly careful during operation and must strictly follow the operation requirements, otherwise it will cause electric shock and fire alarm accidents. .

4. I summarize

I think everyone should already understand the principle of electrostatic spray painting. I have just introduced the advantages and disadvantages of electrostatic spray painting to you. I believe that through the above introduction, you can already discover the key points and advantages, so we are choosing this operation. You must be extra careful when doing so.
