Once you have mastered the basics of your guns, you must become proficient in adjusting the spray pattern of fluid. Many of the guns have a built in air micrometer, allowing variations in pressure settings. If your particular gun does not have this then you can use a separate air micrometer. Width controls the fan spray pattern. Most painters would like to use a wide fan, but we must not forget to spread the fan less materials are distributed.
Many novice painters will complain about the large droplets. It was removed or adjusting fluid needle to allow fluid through the use of less or more pressure.
You will not find this relationship with HVLP guns. They contain only 10ps to atomize. Most of them use the integrated inverter air. manufacturer will provide appropriate inlet pressure to set the cap pressure. This is done after you set the fluid control and select the appropriate nozzles.
to get the best performance from your HVLP gun to slowly increase the intake air pressure, a different fan control. You can do it easily supplies the air cap. It is a double standard, which allows you to check the center, as well as the horn air cap pressures.
the reason that the high performance of the gun is so critical because a lot of new colors on the market contain low VOC and high solids materials. Atomization becomes increasingly difficult as the volume increases color.
Technology Priorities
Now that you have your gun ready to do it perfectly, the job is all up to you. If you're not precise with your painting, you're going to get run, pitting and mottling.
must be in control of his gun at any time in the following areas ...
) judging the exact distance from the gun to the object
b) The correct driver
c) Control the speed at which you work
d) the angle at which hold the gun. This requires techniques such as tilting and toeing Fanning.
e) constantly watch what they're doing, so that they apply evenly. Do you go vertically in a constant even speed. If you go slowly, you will apply more color and if you go you will quickly reduce the amount.
f) Make sure the surface wetting
g) Each passage must overlap the previous application for about 50%
h) Make sure not to double pass in the same area
If we consider the problem of a color flash, and solve the problem of the second pass. There will be some flow after application, but it would depend on the amount of reducer and hardener you use. After the paint is catalyzed although what is shown is what will stay until it corrected.
Do not forget to take your time, follow all the steps and you will master all the weaknesses you have with your spray painting in no time with practice.
