The two-component marking car can be marked by spraying. At present, there are few marking machines using hot-melt spraying in China, only Tiantu marking machine in China can achieve hot spraying. Hot melt spraying marking machine is very popular in the world, because the spraying marking does directly contact with the road surface, so it is affected by the bulge of the road particles, the marking efficiency is higher than the scratch coating, the spraying marking is easy to produce cracks falling blocks. However, there are both advantages disadvantages. The hot-melt spraying marking machine can't draw the neat side line like the ordinary hot-melt scraping marking machine

The cold spray marking equipment includes two-component spraying machine, two-component scraping machine, two-component structure type rain line machine, hand push type cold spray marking machine vehicle type cold spray marking machine. A machine for drawing a zebra crossing lane line on a road. During the construction of the marking machine, put the coating into the heat preservation melting coating box of the marking machine, then introduce the melting liquid coating into the marking bucket, keep the material in the melting flowing state. At the beginning of scribing, the scribing bucket shall be placed on the road surface. Because there is a certain gap between the scribing bucket the ground, when the scribing car moves in a straight line at a constant speed, a neat marking line shall be scratched by automatic flow, the glass bead spreader can automatically evenly spread a layer of reflective glass beads on the marking line. The clearance of marking bucket controls the thickness of marking film, the model width of marking bucket determines the width of marking. Therefore, the scribing bucket needs to be selected according to the actual needs.
