road line paint highway traffic coating powder Hot Melt road marking paint

Hot melt reflective marking paint is mainly used for more than 2 level of the highway and highway, the marking coating thickness of this paint is (1.0 ~ 2.5) mm, the paint is mixed with reflective glass beads, and in the marking construction, the surface of the reflective glass beads. This marking has good night reflective performance, long service life, according to the traffic flow of large highway construction of all kinds of road marking paint demand estimates, small and the quality of the paint itself, generally up to (2 ~ 3) years. The construction of hot melt coating requires special heating equipment. For the second recoating of the old marking line, the thicker old coating should be removed before coating.

Hot melt marking paint is solid powder at room temperature. During construction, the paint is put into the melting kettle, and the temperature in the kettle is controlled between 180 ° C and 210 ° C. While melting, it is stirred, and after melting, it is put into the insulation melting hopper of the marking car. Melt coating then back into the marking bucket, and heat preservation to keep the material molten state. Before the line is marked by the pre-marking machine position, according to the design drawing indicated on the coating position with the lower coating machine primer. The marking coating can be applied only after the coating agent dries thoroughly. When the scribing begins, the scribing bucket should be placed on the road, because there is a certain gap between the scribing bucket and the ground, when the scribing car ahead, by automatic flow and scrape out a neat line. The glass bead spreader can automatically and evenly spread a layer of reflective glass beads on the marking line.

Hot-melt road marking coating uses the thermoplasticity of synthetic resin to make the hot-melt coating have quick-drying
