How to choose a paint panel
When selecting a tool, pay attention to the material from which the paint is made. It is desirable that this should be a nickel-coated aluminium case for corrosion protection. They are made of durable plastic and their main advantage is that they are lighter in weight.
Before you buy the paint panel, check how well the holes are made in the nozzle cover. They are made of brass, aluminum stainless steel. To assess the accuracy of the needle in the nozzle, press the trigger several times.
Another important part of the pulverizer device for paint is sealing pads. In instruments operating at low pressure, good sealing of compounds is particularly necessary. Teflon pads are the most reliable, but they are usually used in expensive professional paint sprayers.
After work, rinse the paint with solvent. To do this, pour it into a tank and use the tool as when working with paint. The atomizer will be clean when the transparent solvent starts to come out of the duse.
The location of the paint tank can be top or bottom. This difference does not play a special role, as does the material from which the tank is made. The metal container is easier to wash, but unlike nylon, it does not allow you to monitor the consumption of paint.
To clean the air head and duse (from varnish or paint), you need to use a brush made of natural bristles.
Types of paints
Total there are three types of paint panels: pneumatic, electric and hand driven.
Pneumatic sprayers have found widespread use for painting. Pneumatic tools spray paint with compressed air. When working with paints, such sprayers can process up to 400 square meters per hour, with varnishes this figure is reduced to 50 squares. Paint and air in the pneumatic atomizer are fed through separate entrances and connected in the air compartment. Thus, a paint torch is obtained.
A compressor is required for the operation of the pneumatic paint console. When choosing the compressor for the paint panel, pay attention to the power of its engine. For the normal operation of most pneumatic sprayers, the average power must be 1.2-1 kW.
At what intensity the air will be spent depends on the volume of the receiver. A compressor with a receiver from 100 to 500 liters will be required for intensive finishing work. For work on average a receiver with a volume of up to 50 liters will be suitable.
According to the method of supply of paint they are divided into:
– tools with suction feed, – sprays with self-flow,
– tools with pressure feed.
In the former, the compressed forms a sparse medium and the paint is initially retracted into the paint console and then sprayed with an air jet. Tank volume in such dispensers is up to a liter and are used for low and medium viscosity solutions.
In the second paint from the top tank gradually flows into the sprayer. The volume of the tank is up to 900 grams. This tool is used during a small repair, for painting works with a small area;
In the third solution is fed from the tank by artificially created pressure. They are used for viscous solutions to perform large amounts of work. The
electric paint gun works from a conventional outlet. No auxiliary equipment — compressor, additional fittings and hoses are needed to work with the electropaint console. It is used to apply solutions, protective mixtures and water-based paints on different types of surfaces. For home construction work, the electropaint console is the most acceptable and economical option.
The supply of paint in electrical sprayers is due to the pressure generated by the oscillating diaphragm. It in turn is influenced by a connecting rod mechanism. With this tool you can paint up to 260 square meters per hour.
Hand driven paints are used for painting with water paints and applying lacquer to small areas. It is a tank with pump and hose. During the operation of the pump, the solution is sucked into the tank, forming the necessary pressure in it, then the paint is fed to the nozzle. The performance of the hand-operated paint panel reaches up to 200 square meters per hour. The
paint spray, which has the solution in the container located at the bottom of the tool, should be kept vertically. This is how varnish will be sucked in, not air.
Preparation for work with paints
To clog the spray nozzle less often, the paint must be strained through a frequent sieve or folded in multiple layers of gauze. The spray tank is filled with paint on 3/4 volume and closed well with the lid.
