Texture of the paint sprayer:
The first spray paint gun was invented in 1888, by Dr. Allen DeVilbiss, in the United States. The paint sprayer plays a very important and fused role in the mechanical system. Mostly paint sprayers are made up of light steel or aluminum. The basic parts of the spray gun are as following:
- Air head, (it has a direct effect on the quality of the result and also has a great effect on the amount of the paint).
- Valve, (which regulates the size of the pattern of the paint present in the sprayer).
- Dip tube (also known as nozzle or peak through which paint comes out through a small hole).
- Pea (a small ball of metal, glass, marble or plastic that is used to mix the paint when the sprayer can is shaken).
- Flow regulator, (it regulates the shape of the paint that comes out through nozzle. It is usually located in the trigger or handle).
How the paint sprayer works?
The work of the paint sprayer is very simple, through which even a normal person can paint in a very effective way. When we press the trigger of the paint sprayer the air is pushed downwards, suppresses the mixture inside it and when it is released the paint comes out with the air hay. You can use it again and again, but when you want to use it a second or third time, you must first shake it, because the paint in it is a suspension solution. By shaking it, the pea in it mix the paint again that is accumulated in the bottom of the can.
Types of the paint sprayer:
There are many types of the sprayers depending upon their qualities like pressure, and paint transfer mode etc.
- On the basis of the pressure there are many sprayers are available having:
- low pressure manuals
- high pressure manuals
- high pressure automatic
- low pressure automatic.
- On the basis of the paint transfer mode, the types of the sprayers are as following:
- Airless paint sprayer
- Airless assisted
- Conventional
- HVLP
- Electrostatic
What is airless paint sprayer?
It is a specific system in which spraying ad coating of paint takes place at very high pressure. The speciality of this spraying system is that the air is not mixed with the paint during the whole process, even air is involved in this process. In this airless system, there is the key role of the pressure of the piston pump, which compresses the paint when passing through the nozzle or peak of the sprayer can. This in turn passes through another hole of longitudinal or angular shape that provides the flash and smooth pattern. The coating should not be sprayed repeatedly as it causes the paint to bulge and spoil the smoothness. . This system is ideal for applying high viscosity paints, (the viscosity of a liquid is a measure of its internal resistance to flow or, simply put, its thickness), such as plastic paints. These type of things need more energy and power to apply paints.
Advantages of spray guns:
There are many advantages of the airless paint sprayers. Some of the most popular advantages are as following:
- Paint can be applied to different types of surfaces in a very effective and smooth way.
- This system is also very effective for coating or painting uniformly and smoothly, even on irregular or rough surfaces.
- It is a very quick process, hence it can save your precious time and also saves your money which may be wasted on the production costs.
- It is an automatic spray gun. You just have to trigger it.
- Airless paint sprayer has many specific applications.
