Introduction to electrostatic powder paint

Furnace or electrostatic paint is an industrial paint that is produced in both powder paints and furnace liquid paints in the paint and coating industries and has wide applications in the field of painting a variety of metal surfaces. In other words, electrostatic powder paints are the best type of industrial paint that has the least environmental damaging effects and does not threaten the health of workers. Currently a wide range of furnace paints are used to paint different surfaces. The choice of using powder or liquid electrostatic paints depends on the factories of consumers, but furnace powder paints seem to be the best choice for the metal industry. In the following, you will learn more about the furnace color, how it is painted, and its application principles. Please join us.
Advantages and Disadvantages of Furnace or Electrostatic Paint

The furnace dyeing process (electrostatic paint) involves operations in which the powdered pigments or, in fact, the same solid pigments are applied to the surfaces by chemical bonds and electrical processes. Furnace paint particles are sprayed onto the surface through special equipment. In this case, the metal surfaces absorb the negative charge pigments; the negative particles are rapidly absorbed onto the metal surface by positive charges. Oven painting is the most effective technique for painting metal surfaces and covers a variety of applications. In this section we will learn about the most important advantages and disadvantages of powder colors.
Superior performance, high efficiency

One of the most important advantages of using a variety of furnace paints for painting metal surfaces is the high efficiency of these materials. Electrostatic paints have a higher efficiency than other types of paints and industrial coatings. The reason is quite clear. The powdered pigment particles are electrochemically applied to the metal surfaces; the result is a staining, high fineness, short drying time and a flawless surface. This method is especially important for painting metal furniture, car body and home appliances as the final coating.
High startup costs

The high cost of a variety of electrostatic paints and coatings is one of the disadvantages of using this method for painting metal surfaces; the equipment required for painting with a furnace color is very expensive compared to a simple air compressor system and devices must be expensive. Work at high pressure. For example, to buy an air spray paint system, it costs about 1 million tomans and about one million tomans to buy smoothing and polishing equipment; the price of buying a whole electrostatic powder paint unit is something. It will be 3 million tomans.
Very limited target market

Furnace paint methods have a very limited target market. This approach is often applied to manufacturers of metal office furniture, automotive and industrial metal appliances; however, access to wider target markets requires stronger marketing methods and more rigorous pricing systems. It seems that if a business or contractor working in the field of electrostatic paint cannot handle marketing well, it will not be able to grow and expand its business, which of course This is a disadvantage.
Application Principles of Furnace Painting

Now that you are familiar with the advantages and disadvantages of different types of furnace paints, their use in painting metal surfaces, it is time to learn more about the furnace paint process. The general principle of a stained-glass staining method involves an electrostatic spray system operating under an electric field and the effects of charged particles. Let us illustrate this concept with an example.

You must have ever seen woolen clothing or plastic surfaces able to absorb hair or hair, precisely because there are charged particles on the plastic or wool surface that can absorb other particles. This phenomenon is exactly what happens in the staining method. Thus, the basis of the electrostatic staining method can be considered as applying a suitable coating on the metal surfaces resulting from the adsorption law between positive and negative charged particles.

The principles of stained-glass paints are as follows: aerosol powder particles (aerosol solid particles) are removed from the bottom of the spray gun nozzle; this process is performed using compressor pressure . In this case, if a large surface painting is desired, the painter can direct the nozzle particles to other parts by moving the spray gun, but if the point coloring is desired, the nozzle head is adjusted to the designated area. Is coming.

When the particles of a furnace paint come out of the gun nozzle, they charge positively. These charged particles are capable of describing the forces under the electric field. Liquid particles of positively charged electrostatic dyes are attracted to the negatively charged metal surfaces, as is the case for magnets. The Columbus law applies to electric charges in this way.

The Corona Discharge Act applies to powder paint staining. According to this law, solid pigment particles are ionized by electric field and are discharged as positive charged particles to the metal surfaces. Electric field
