the principle of spray pen

the spray pen is a precision instrument, which can produce very fine lines and soft and gradual effects. At that time, the role of inkjet pen was to help photographers and painters use it to modify the picture. However, the potential function of inkjet pen was soon recognized by people and was widely used and developed. The artistic expression of the pen is vivid, and the depiction of objects is perfect and unique, with delicate and natural light and shade levels and soft colors. The spray pen must be used with the air pump, because the spray pen must have a gas eruption to spray the paint.

With a coordinated valve stem combination, the air flow and pigment flow can be controlled, and the plate switch can be started up and down and can slide horizontally. When sliding horizontally, the rear connecting rod of the stopper rod pushes the throttle needle to control the amount of color entering the airflow. By pulling back the throttle needle, the cross-sectional area of the gap of the nozzle is gradually increased, and the spray angle of the mixed gas is also increased. The spray sample is a coverage composed of countless fine particles. Every particle is atomized and sprayed on the screen in a saturated state. At the moment of atomization, the water in the color evaporates rapidly, and the color sprayed on the screen is almost dry. The wet and dry change of color is very small, and the color change is easy to grasp.
