How to make a spray booth with your own hands: for powder coating and furniture

If we consider the painting of large equipment, for example, cars, then at the moment the most relevant method of painting is dry powder coating. The point is this: the required amount of dry powder is deposited on the surface to be painted. Next, the working surface is heated so that the powder melts and the particles are firmly connected to the surface. To achieve the result, it is necessary to create ideal conditions for air purity, temperature and pressure; accordingly, a separate painting chamber is built at the production site.

What is a paint booth

The spray-drying booth is often used for painting work on cars and trucks. A special feature of the chamber is the presence of a special ventilation system and temperature control.

So that when painting, no small particles can get onto the paint layer. And also during drying, the necessary temperature conditions are created for the process to proceed correctly.

The powder paint polymerization chamber is distinguished by a special system for influencing the layer so that the adhesion strength of the composition is high.

Thus, the painting chamber is the place where the required conditions are created for applying and drying the paint and varnish material. Depending on the type, the arrangement of the room will differ.

Recommendations for selection

When choosing the right paint, it is important to pay attention to the speed of color change. Cleaning, or rather the process itself, is also important. Therefore, the number of filters is directly related to shades.

The cameras are equipped with various equipment for operation. For example, a manual or automatic spray system. The machines are fixed both motionless and on a manipulator. For the latter, it is possible to choose several degrees of freedom.

It turns out that it is better to choose according to the following characteristics:

• Shape and size of processed parts (products for powder coating).
• Performance calculations.
• Color change rates and their total number.
• Energy carrier.

This is the only way to achieve benefits by controlling costs and quality of coatings. Yes, and one more thing: the price of a finished powder paint chamber directly depends on the configuration and workload during production.

There are companies that assemble such spray booths according to individual requirements or preferences.

Any design has specific areas for the painting process, as well as differences in size and price. If we consider the dimensions, then it is not the dimensions that are important, but the working volumes of the chambers. Therefore, for specific needs, you can select the required volume in advance. That is, when choosing, they must focus on working and production issues, on the parts that will be processed.

Advantages and functional features of the paint box

A car painting booth has a number of advantages over working in a regular garage. Due to the special arrangement, the possibility of dust and other contaminants getting onto the base after applying paint is eliminated, which is very important when covering the surface of a car.

There is also the possibility of creating a homemade camera. The process is not so complicated, if you do not violate the technology and take into account fire safety requirements, the result will be of a high level.

Due to the special arrangement, the possibility of dust and other contaminants getting onto the base after applying paint is eliminated.

What is powder coating?

This term refers to the creation of high-quality decorative and protective polymer coatings by using a high-voltage electrostatic field. Powder paint is a tinted fine powder with impurities with a grain size of 10-100 microns.

The essence of painting work is to apply a powder material charged during the spraying process by electrification through friction or from an external source onto an oppositely charged metal surface.

This ensures uniform application of paint to the object being processed. Powder painting involves the use of a polymerization chamber for drying and final fixing of the paint.

Varieties

The equipped room can be done in different ways; the requirements for the arrangement depend on what they intend to paint. This could be a car, furniture, or other parts. For example, there is a chamber for powder painting. Therefore, you need to understand the types of cameras in order to choose the appropriate option.

Subspecies and their features

Nowadays many subtypes of such cameras are produced, and the range is only expanding. The structural components are:

• Dead end.
• Checkpoint.
• Two-post.
• Single post.
• With cartridge filter.

Let's look at the characteristics of some of them.

Single post:

• It has a recuperator equipped with a single filter.
• Can handle up to 99% of airborne paint spray.
• The filter is cleaned as follows: blown manually or using automatic mode.
• Power not less than 3 kW.
• Working space (standard): 1700 x 1100 x 2000 mm.
• Weight – 390 kg.

Two-post (marking KO2):

• Pass-through type.
• It has two recuperators and two replaceable filters.
• The technology for re-cleaning the paint has been developed (up to 99% of the sprayed composition is returned to work).
• Filters can only be cleaned with pressurized air.
• Power from 5 kW.
• Working space 1700 x 1100 x 4000 mm.
• Weight – 640 kg.

This type is most convenient when processing parts from several sides. The products pass through openings for spraying on both sides. This is convenient when two system operators are working at once.

With a cartridge filter, the powder coating booth is equipped with:

• Paint booth.
• Replaceable filter system.
• Filter cartridges.
• Sieve with vibrating mechanism.
• A container for selecting paint with filters.
• Powder injector.
• With a scraper.
• Compressed air filter blowing system.
• An absolute filter.
• System for supplying clean air.
• Lattice.

There are also special working moments specifically for this type. They are as follows: due to draft, air with powder paint is supplied. All this goes through the cartridges. The paint is sifted and poured into the receiver. Then this composition is fed into a powder coating gun. All excess that remains on the filter is removed with compressed air. And if there is a lack of paint in the system, the sensor lights up.

Most often they buy and use walk-through models of powder chambers, because they are part of a painting line integrated into a common transport system.

The chamber helps to start the required air flow in the room, clean it of contaminants, and eliminate harmful substances present in the paint.

Sequence of work

The powder coating process includes several stages. The first of these is surface preparation, which involves removing any contaminants from it. In case of repainting, it is necessary to clean the surface of the original paint and primer. These works are carried out after drying is completed using sandblasting, using various abrasives. Coarse ones are designed to quickly remove paint and varnish material, while inorganic materials are used to level the surface.

Next, powder primer is applied to the prepared work surface. This process is carried out in a spray chamber using an electrostatic sprayer. The workpiece must first be grounded. Powder primer, like regular primer, serves as anti-corrosion protection. After the soil has melted in the spraying chamber, powder paint is applied. This work is also carried out with an electrostatic sprayer. To create a smooth, uniform coating, the paint should be applied in several layers (usually 2-3).

After each layer, the product to be painted is placed in a polymerization chamber for 15-30 minutes, where, under the influence of a high temperature of 180-200 ° C, powder paint particles are fixed on the surface of the part due to melting. Upon completion of drying and polymerization, the part to be painted is removed from the chamber and left for some time - this is necessary for it to cool to room temperature.

Upon completion of paint application, the part is coated with powder varnish, which performs protective and decorative functions. It gives the coating additional stability and protects it from fading under the influence of ultraviolet rays. In some cases, varnish is applied to metal that is not covered with paint and primer in order to preserve its texture. In addition, in this case it plays the role of an anti-corrosion agent.

Mode of application of cleaning and ventilation systems

Air masses are purified through three filters: coarse cleaning, where dust and heavy particles are removed; cleaning, the filter is located behind the heating element; fine cleaning, which is located behind the air duct.

It is necessary to install the filtration system so that filter replacement is easy.

Important Safety Precautions

When interacting with oxygen, powder dyes become explosive. Therefore, one of the most important requirements for a painting device is explosion protection.

In production spraying units for painters, a recovery device is installed. It is designed to collect powder. Otherwise, paint particles will spread throughout the workshop.

The recovery system is an important auxiliary equipment of the spray booth. It is equipped with replaceable filters, exhaust fans, a receiver and a mechanism for supplying air flow under pressure.

Heating system

Working temperature standards must be observed in order to obtain a high-quality result without putting the painter at risk of health problems. The following points can be noted regarding the heating system:

• Conventional heating and electric heating elements will be sufficient for the winter period;
• A heat gun will help warm up the room and ceiling areas;
• A heat generator is only needed for large jobs, otherwise the expense is not justified.

Working temperature standards must be observed in order to obtain a high-quality result and not expose the painter to the risk of health problems.

Interior decoration and arrangement

For interior decoration, it is advisable to use non-combustible materials in order to comply with safety standards. This is how a metal profile is often chosen. Also, non-combustible materials are selected for thermal insulation work.

For ease of work, an area is allocated for storing the necessary equipment and materials.
