Road marking machine is a kind of pavement machinery for marking various traffic markings. It can draw different restrictions, guidelines and warnings on roads, high highways, parking lots, squares and runways on the flat ground. . Next, the editor of the 258 platform will introduce the introduction and classification of the underline machine.
During construction, the road markings are different and the marking machines used are also different. The marking machine can be roughly divided into three types: room temperature paint marking machine, heating solvent type marking machine and hot melt coating construction machinery.
Normal temperature paint scribing machine is the most used one at present. According to the operation mode, it can be divided into two types: push type and vehicle type. The former is mainly used for small-scale operations such as pedestrian crossing lines, parking azimuth lines, and parking lines; the latter is a self-propelled scribing machine modified with a special chassis, which has fast construction speed and flexibility, can be used for large-scale scribing construction, and is mostly used for high-speed Crossing of highway.
According to the spraying method, the room temperature paint scribing machine can be divided into low-pressure air scribing machine and high-pressure airless spray scribing machine. The low-pressure air marking machine uses low-pressure air to generate negative pressure in front of the nozzle to suck out the paint in the container, atomize the paint, and spray it onto the road to form a marking coating. The air spraying method can make the paint atomize finely However, there is air bounce and the paint scatters seriously. The marked line has burrs, and only low-viscosity paint can be sprayed.
Air spraying has been replaced by high-pressure airless spray marking machine due to its many defects. The high-pressure airless spray marking machine has a good spraying effect. Although the atomization is not as delicate as air spraying, there is no air rebound. The marking line is neat and full, and the spraying is strong and the adhesion is good. It can spray high-viscosity paint. The life of wire coating is significantly longer than airless spraying. High-pressure airless spray marking machine can be divided into diaphragm type and plunger pump type.
