Powder coating equipment
Powder paint forms a tough coating that is harder to damage by mechanical or chemical attack. Even after prolonged use, traces of use are very faintly visible on it. And also powder paint makes it possible to use different colors and textures of the coating: antique, moire, shagreen, metallic and others.
Thanks to this, powder paint has replaced liquid paint in many areas. And the scope of its application is constantly expanding.
The only drawback of powder paint is that for its application you need special equipment, which is installed in production.
Therefore, we decided to devote this article to what equipment is needed for powder painting.
Spray guns
Powder is sprayed onto the product with a gun. There are electrostatic and tribostatic models. The difference lies in the way the particles are charged. For the former, an external power source is needed. The latter do this by friction: paint particles rub against a special surface of the gun barrel and are charged. Tribostatic models are better for painting parts of complex shapes, because the lack of electric current in the work allows you to avoid reverse ionization and crater formation. But electrostatic is better if you need to paint a lot and quickly paint parts with a flat surface.
Камера напыления
Камера напыления необходима для того, чтобы оградить покрасочный участок от остального помещения и собирать не осевший на поверхности порошок. Она имеет вентилятор и рекуперационную систему. Камера обеспечивает безопасность работы. Вентилятор убирает лишний порошок, чтобы он не мешал работе. А благодаря рекуперационной системе собираются частицы краски, которые не осели на поверхности, просеивает их и возвращает в работу.
Камеры бывают тупиковыми и проходными. У первых есть лишь один проем через которое деталь, загружается, окрашивается и выгружается. А вторые имеют несколько проемов: для загрузки, окрашивания и выгрузки детали. Они устанавливаются на автоматических линиях покраски.
Polymerization oven
The polymerization oven is a closed chamber for heating the painted product. The coating is directly formed in it.
Depending on the type of oven, it can heat the product up to 180-200 degrees. It is equipped with a special control panel on which you can fully regulate the operation of the device.
Polymerization ovens can also be dead-end and through-pass. And the latter work on an automatic painting line.
Powder coating technology
Polymer powder painting, the equipment for which we described above, is divided into several important stages.
Before powder painting, the product must be cleaned of all possible contamination, degreased and rinsed.
Then it should be dried.
After that, the product is suspended in the spraying chamber and the powder particles are sprayed with a gun. The dyed article is placed in a polymerization oven where the coating is formed. After painting, it can already be used.
Safety engineering
In order for powder painting to take place without harm to health, several rules must be followed:
- When working with the equipment, you must take care of the grounding of all parts and the painter. Dyeing should be done without gloves.
- There must be a working ventilation system in the room.
- There should always be fire extinguishing equipment nearby.
- It is impossible to paint in the same room with powder and liquid paint.
- It should be painted in specials. clothes.
If you decide to switch to powder painting, our specialist can calculate the cost of the equipment for you. It will depend on the specifics of production, the workshop in which the painting will take place, and the amount of work.
