high pressure airless spraying roadway marking paint

high pressure airless spraying roadway marking paint. Have crossed spray pressure is generally not high, the largest 8MPa, film thickness of about 0.2mm. Proof of actual use, the use of road marking spray program period is generally 2 to 4 months, some even a month or so lines trace began to peel off, become blurred. Spray pressure is low, the film is thinner, and the ground of the differential adhesion properties, the film in the ground a long residence time, after a longer period of time required to gradually penetrate the formation, the surface can be dried, so that crossed the parking time increases, the impact on traffic ; can not guarantee completely blocked traffic will be traveling vehicle rolled stem new line, destroyed the lines clean. Therefore, we should use of a new high-pressure pump to start, to improve the spray pressure to ensure the quality of crossed. The new marking machine adopts high-pressure airless spray paint pump, the pump pressure up to 20MPa, increasing the system pressure. Under high pressure, so that the paint by high pressure, is injected into the ground, paint sprayed into the formation and seep into the ground material porosity, the paint line drying speed up, greatly improve the adhesion, film thickness up to 0.5mm . By the use of research, the use of this method using the same materials crossed the paint line use for a period of 4 to 6 months, life expectancy has increased more than doubled, and spray program lines burrs and paint flow phenomenon, clean and beautiful, to meet the requirements.
Scriber injection components should work according to the crossed requirements and marking machine for a reasonable choice. Top injection nozzle member, but various types of nozzles are optimal spray distance or the ejection angle range, Click the range of the nozzle is arranged in the corresponding position of the scribing machine. The distance is too high, and causes the nozzle angle increases, the line width increases, the lines are not clear, and the film thickness is reduced; distance is too low, the injection angle is reduced, the increase in film thickness, drying time, and easy to produce paint flow phenomenon . The nozzle selection should also be consistent with the performance of the paint, and arranged in the proper position of the marking machine, to comply with the requirements of the nozzle operating range. Injector atomization of paints, a uniform thickness, the line segment is clear, full of traces, to meet the requirements.
