The manual tribostatic spray gun is designed for autonomous spraying of powder paint from a tank mounted on a spray gun. Only dry compressed air is required for operation. Indispensable for painting small batches of parts where frequent color changes are required. Easy to disassemble, clean.
When painting complex parts, it is easier to use a powder spray gun with tribo-charge.
As a rule, the productivity of the process of applying spray guns with tribo-charge is reduced, and the percentage of sedimentation of powder paint on the product is lower than when using spray guns with a corona electrode. Inevitably, a gradual decrease in the effect of tribo-charge with a decrease in the total charging voltage of powder paint, an increase in the fraction of uncharged powder and, accordingly, not deposited on the part as additives are developed in polyester and epoxy-polyester paints, are also inevitable. By the electrostatic method, it is possible to paint products of different sizes and complexity groups and apply virtually any kind of powder paints. A necessary product requirement is volumetric or surface electrical conductivity. It is easily realized when painting metals. In the case of non-conductive materials (wood with a moisture content of less than 12%, glass, plastics), measures are taken to increase conductivity: for example, the surface is treated with antistatic agents – surfactant solutions or conductive primers.
The advantage of this pistol is its ease of use and, at the same time, its reliability and performance for a long time. Simple set-up and ink exchange combined with the low cost of the gun are widely used in the field of polymer powder coatings.
The gun is supplied ready for use, just connect the dry compressed air hose.
Epoxy-based powders are best suited for painting, as well as epoxy-polyester with a predominantly epoxy component.
Adjustment of the torch at the outlet of the nozzle barrel is carried out by the amount of compressed air supplied to the injector, by displacement of the bell at the exit from the barrel, by replacing a reflector with other dimensions, by installing additional devices (for example, a slotted nozzle);
The supply of the coloring material to the painting area is carried out by pressing the trigger on the spray handle.
Since the gun charges the powder electrokinetically, it does not need a high voltage source.
The electrokinetic charge maintains high coating efficiency, including even deep voids and fins.
Lightweight flexible air hose provides good mobility of the gun.
The presence of an air pressure regulator simplifies the introduction of the gun into operation and its further use.
