How to Make Accurate Road Marking by Machine On the Road?

Let's introduce the most popular way when making marking on the road: Hot melt road marking paint is solid powder at room temperature. In construction, the thermoplastic paint was put into a melting kettle called thermoplastic pre-heater, to mix and melt into the molten flow state.
Then the melt paint was transferred into the paint tank of hand-push marking car, and then the molten coating will be introduced into the marking bucket and the material insulated remains molten. When the marking work starts, the marking bucket should be on the road surface.
Because there is a certain gap between marking shoe and the ground, when the marking car was pulled forward, by automatically flowing, a neat marking lines was scraped out, glass beads sow can automatically evenly spreading a layer of reflective glass beads on the coating lines. The gap of marking shoe controlled the thickness of the coating.
Every road marking machine has a hydraulic guide rod to ensure the painting line accurate and straight. Besides, before painting, the road surface was premarked a line by an auxiliary equipment pre-marker.
