Spray gun nozzle

No spray gun will work unless it is equipped with a special nozzle. For high-quality application of paint to the surface, it is necessary that the nozzle is not only correctly configured, but also correctly selected. It is also important to know the rules for operating the device.

The spray gun nozzle is a special nozzle through which paint is sprayed from the container. The principle of operation of the device is quite simple. From the container, paint is captured and passed through the hose. This is done through increased pressure. So, the paint goes to the spray gun. There is a small hole through which the paint comes out at a certain speed and at a given angle.

It is noteworthy that the parameters of the supply of the dye can be adjusted. So, a well-chosen nozzle allows you to distribute the paint with the required feed width... The spray gun can be sold as a complete set with the rest of the elements, or separately.

The spray gun nozzle is designed to distribute paint or other substance from the container. Depending on the settings made, the paint will be dispensed at a certain speed, pressure and width of application.

By purpose, the nozzles can be divided into several categories, depending on the device itself. So, the nozzle for electric and mechanical spray guns will be different from each other. There are also special nozzles for airless paint sprayers..

With the help of a nozzle (with the general operation of the entire device), the paint is distributed to various surfaces in the room.

To a large extent, the quality of paint application depends on the correctly selected nozzle for the spray gun. When choosing a device, first of all, you should focus on the type of proposed work.

So, the electric option is suitable for processing surfaces such as:

• facade;

• fences;

• tanks;

• doors;

• gazebos.

The pneumatic version is ideal for painting cars, refrigerators, trailers and other similar surfaces.

It is equally important to choose the right nozzle diameter for the spray gun.

So, depending on the substance used, the hole diameter should be different.

1. For base enamels, a diameter of from 1.3 to 1.4 mm.

2. Acrylic enamels and clear varnishes - not less than 1.5 mm... The same diameter can be used when applying liquid primary primers to the surface.

3. Filler primers apply well through a nozzle diameter from 1.7 to 1.8 mm.

4. Nozzle suitable for liquid putties from 2 to 3 mm.

5. For anti-gravel coatings, the diameter should be not less than 6 mm.

In the case of an incorrectly selected nozzle, the substance will be applied poorly.

It is necessary to use the device in accordance with the rules prescribed in the attached instructions. The main thing to consider is choosing the correct nozzle diameter. Otherwise, it may become clogged. In this case, you can clean it yourself. To do this, you need to prepare the following:

• paint thinner (ordinary water is suitable for water-soluble formulations);

• convenient medium-sized container;

• toothpicks, cotton swabs or special brushes;

• a small piece of lint-free cloth;

• the key of the required size.

It is necessary to unscrew the tank and put it in a container with solvent. Next, an air head must be placed in the same solution. Then you need to remove the nozzle and press the start key all the way. The hole must be cleaned with a needle and cotton swabs previously soaked in solvent. Dry all parts and reassemble in reverse order.

Everything must be done carefully so as not to get damaged and not break the device itself. This procedure should be carried out immediately after clogging.
