Paint sprayer dispersion technologies.
As we know, there are several kinds of paint sprayers models, which differing in the working pressure and volume of air. Each of them has a certain dispersion system. It is possible to distinguish 3 main (most popular) systems of paint sprayers: HP, HVLP, LVLP. Here you will find more about them. To find more about paint sprayers itself visit www.paintsmoothly.com
HP (high pressure) system. Initially, there was a device with the technology of HP, having the high level of working pressure (to 5-6 bars). Soon it was succeeded by the RP system with similar characteristics. It should be noted that under such indicator as pressure not entering pressure but the one proceeding from a dispersion head. It means that if an input parameter is equal to the 2-3rd bars, then at the exit pressure will make 1,2-1,5 bars.
What do such sprays differ in? They consume the air necessary for work slightly (on average 200-270 l/min.) in comparison with HVLP, LVLP devices. The device with this technology will be perfectly suitable for use both in life and during large volumes of works. It is recommended to use the RP system for putting materials with the small content of solvents.
Using of this coloring system makes painting quicker at the expense of a wide torch, but, unfortunately, it has a very small transfer of material on a surface. The device does not differ in profitability. Paint and varnish production is sprayed under the high pressure, therefore, adhesion makes only about 45-50%. .The recommended distance for coloring is about 35-40 cm from a surface.
HVLP system. HVLP system provides big transfer of paint with a low pressure. Air consumption by such airbrush is in limits of 360 l/min, sometimes and to 500 l/min. Therefore if there is no compressor of big power, then it would be difficult to work with it. But, nevertheless, this technology allows regulating pressure level enough in the big range of 2-5 bar.
From its advantages, it is possible to note low loss of paint (no more than 25-30%) in spite of the fact that at an entrance the recommended pressure in 2-2,5 bars but on the spraying head this parameter equals 0,7-0,9 bars. The only shortcoming, strangely enough, is his advantage, namely: high coefficient of transfer of material on the painted surface. Here the explanation is necessary. If in the course of works you will be staying too long in one point on fractions of a second, then the big risk of formation of smudges appears. Therefore it will be difficult for the beginning painters to adapt. The painting is made in 15-20 cm from a surface.
LVLP system. The equipment, which working on LVLP technology carries out transfer of a small volume of material on a surface with a low pressure. The device gives an opportunity to use the compressor of low power and preserve the painting structure (here loss does not exceed 25%).
Air this system requires 200-300 l/min. It is considered that such paint sprayers possess the most optimum characteristics – they much more economic than RP technology (air consumption) and HVLP paint consumption). The distance to the painted surface makes 20-30 cm. In principle, the most of the similar equipment works on above-mentioned technologies.
