Pneumatic spray pen use related

The spray pen can be divided into single action and double action. Single action is that there is only one button on the spray pen, and the paint can be produced when pressed, and the paint quantity cannot be controlled. On the basis of a button, a knob is added at the tail of the spray pen that can move the spray needle back and forth, so that the gas and paint can be divided into two steps and the amount of paint can be controlled. Spray pen capacity in 3cc-24cc range, caliber 0.2mm-0.3mm (advanced goods can be smaller or larger), divided into the pot, side pot, pot of three forms.

The transmission mode of the spray pen is dependent on gravity, so the nozzle of the spray pen needs to be downward at all times. Another advantage of this is that the paint in the pot will not pour back to the back of the spray pen, cleaning the spray pen becomes very easy, otherwise the paint will dry and stick to the thimble of the spray pen, not only inconvenient cleaning, but also affect the use of the spray pen.

The correct way to use the spray pen is to press the button down with your index finger, and the spray pen will spray the air, and then gently pull back, and the paint will spray out. Just spray it to the place you want to spray it, and remember that the nozzle is slightly downward.

Before using the spray pen, it is necessary to check whether the spray needle and the fixing screw are fixed tightly. Can line with some diluent to whiteboard, napkin test spray, feel the degree of fog and distance. When it first touched, the gas output was relatively large and the paint of the pen nozzle was not uniform, or the pen was not cleaned. Spraying directly into the model will be a little undesirable phenomenon, so it is necessary to start the operation after a few seconds after painting.

Some people say that alcohol can be used to wash the pen, not not acceptable, is not ideal. Because alcohol doesn't dilute model paint particularly well. Brand name thinners such as Tamiya Water thinners and Gunshi-2 thinners are ideal. (blue label type) Residual model paint in the model spray pen after spraying, if it is the primary color of unblended paint can be directly returned to the bottle. Wipe off the remaining paint in the pot with a paper towel. At this time, drop some thinner into the pot, shake it, wipe the bottom of the pot with a cotton swab, pour it out, and then drop some thinner with a paper towel to stop the spray, shut up, operate the spray pen. At this point, the air flow is reversed, which is a simple wash pen. Remove the spray needle after washing, wipe it clean with diluent, install it well, spray the diluent out of the residual pen, wipe it with paper towel. You can also put a few drops of thinner into the spray pen at the end so that the spray needle and the inner cavity will not stick because of the remaining paint when you use it for a long time. Do not wash the pen after each use. First, it is necessary to maintain the pen. Second, the next spray paint will not be flat or atomized, which will destroy the model.
