The airbrush is an irreplaceable attribute in the workshop of any home craftsman. At the same time, we note that it is not at all necessary to use it only for painting a car, because this device can also be used during ordinary painting work in everyday life. The main thing is to know how to choose a spray gun so that it is convenient to use.
How it works
The airbrush is a device which needs to be used correctly. And for this you need to know his device, possible adjustments and settings. Today, many manufacturers offer to buy this device, which only complicates the choice. It is noteworthy that the atomizer was first coined by an American doctor to administer a medication to the nose.
Today the device has significantly transformed, and the question arises of how to choose the right spray gun. The design features of these devices are such that the flow of compressed air is controlled by the trigger. In this case, the tank itself, into which the paint is poured, can be located above or below. By adjusting the air flow and selecting the spray head with different diameters, you can control the process of spraying the composition. In order for the device to work stably, it is important to know how to choose a compressor for the spray gun.
Design features
Any spray gun is a simple device in composition, which even a novice user can handle. The device turns on via the network. A piston is launched through the armature, the reciprocating actions of which lead to the suction of the sprayed material through the filter into the chamber of the device. Here, the material is compressed, then pushed out using a spray gun and nozzle. That is, using a spray gun is simple: paint is poured, after which you can begin to work with an already cleaned and high-quality prepared surface.
How to choose paint for a spray gun?
In order to paint a car well, it is important to properly configure the device itself, with which we will apply the composition. Several factors affect spraying:
- Properly diluted paint.
- Properly selected air pressure.
- Precisely set torch size.
- Correctly organized supply of coloring material.
The most important thing is to prepare the paint of the desired degree of viscosity. It depends on this stage how well the composition will be sprayed. To do this, paint is taken and mixed with an activator - the proportions are indicated on the can. Due to the high viscosity, this mixture cannot be used yet - it is still necessary to add a solvent to it. We need to approach this point responsibly, since the quality of the final product depends on the quantity of the latter. This creates a mixture that will be applied in a single layer.
How to choose a spray gun for water-based paint, so that the coating pleases with high quality? It is necessary to properly configure the device taking into account the width of the torch, air pressure and adjustment of the paint supply.
Adjustment Features
Before choosing a spray gun for the home, you need to decide for what purpose it will be used. This device includes an air supply unit and a spray gun through which painting is performed. In the form of a block for air supply, a compressor, a manual pump or an air duct can act. And to control the level of paint ejection, you can choose models with a built-in electric motor or plunger pump.
How to choose a spray gun - pneumatic or electric? It all depends on the device spray gun.It consists of a housing, a paint tank, which holds up to one liter of composition. The lid of the tank is equipped with a special drainage hole, which should be cleaned periodically to avoid the formation of vacuum inside the tank.
Air and paint are supplied with a special trigger located on the body. When we easily press it, air is supplied. With a strong press, the needle is affected, which moves and opens the channel necessary for the receipt of paint. The main part of the sprayer is a head with a nozzle made of brass, bronze or ceramic, of different diameters. The smaller the size of the hole, the smaller the droplets of protruding paint. The enlarged opening allows you to spray liquids with a high level of viscosity. When deciding which spray gun to choose, pay attention to the models in which the head comes complete with interchangeable nozzles of different diameters.
Using special adjusting screws, the shape and size of the spray cone are controlled, as well as the amount of paint sprayed and the air pressure. Adjustment should be carried out taking into account the viscosity of the composition, as well as the size of the painted parts and the type of painting (it can be draft or finish).
Classification
How to choose a spray gun? First you need to decide on the type of spray. All models of devices are divided into several groups, depending on the volume and working air pressure:
- High pressure (HP).
- High volume, low pressure (HVLP).
- Low volume, low pressure (LVLP).
- Low volume, medium pressure (LVMP).
- Low Pressure (RP).
- Medium Pressure (MP).
- With high pressure efficiency (HTE).
The main differences are between the spray guns of the HP, HVLP and LVLP systems, and the rest of the devices are their modifications. The most popular models for buyers are with the spray system based on the HP system. The main advantage of this version is the wide torch, which provides uniform coating on the surface, increasing the speed of repairs.
Among these models can be noted the Expert HP device, which is equipped with a gravitational supply of paint. It is suitable when we choose a spray gun for painting a car as simple as possible in action. Its effectiveness is due to the fact that the device can be used for paintwork, tinting and priming surfaces of metal or wood. The base nozzle has a diameter of 1.4 mm and is made of stainless steel, anodized aluminum is used to create the air nozzle.
How to choose a spray gun that will allow you to rationally spend paint and varnish materials? You can pay attention to models with the HLVP system, which work without swirls of paint, ensuring the formation of a uniformly painted surface. LVLP systems are characterized by low air consumption, low sensitivity to differential pressure, as well as high-quality application of paints and varnishes on the parts.
Selection rules
Before deciding how to choose an electric spray gun, you need to decide how often the device will be used by you and for what purposes - domestic or professional. Such parameters as power and efficiency of the device will depend on this. By the way, for professional activities, the painter needs at least three apparatus for spraying paint of various types of action. The best option is a spray gun of the LVLP system, however, when choosing, you should still proceed from several parameters:
- Nozzle size. You should take into account the power of the spray gun, as well as the type of coating. For example, for a metallic base coat, the diameter of the nozzle should be 1.2-1.3 mm, and for varnish and acrylic, 1.4-1.5 mm.
- Spraying method, especially if a primer is to be applied.
- Type of spray. A modern buyer can purchase an electric, pneumatic or mechanical device.
- DimensionsAll models on the market are focused on either industrial production or domestic use. The former are distinguished by greater power and the ability to paint immediately a large surface in one approach, the latter are convenient in that they are compact, so they can be used to decorate hard-to-reach spots.
