The advantages of the hand scraping scraping two-component marking machine are that the service life of the equipment is long, it can be used for 3 to 5 years, the reflective effect is good at night, the pollution resistance is strong, the brightness can be maintained for a long time, the adhesion is good, the wear resistance durability are good. The construction of hot-melt coating shall be prepared in advance, the necessary tools for on-site placement of safety facilities to repair the marking mark, the ash bag for marking the standard line, the necessary drawing board type shall be prepared. Features of hot melt marking machine

Marking equipment is complex, construction efficiency is low safety is poor. Most of the hot-melt coating construction is to use the hot-melt kettle to melt the coating at high temperature, then turn to start the manual scraping marking in the pusher marking car, which has high labor intensity, low construction efficiency, high temperature operation risk, fuel consumption environmental pollution. In addition, there should also be supporting construction equipment, such as car loading hot melt primer sprayer, old line cleaner, etc. the complete set of marking equipment has a wide range of types is expensive. Hot melt coatings have the following disadvantages

The two-component marking system is a two-component system, the two components must be mixed. The pipeline of the marking machine supplying the two components cannot be mixed all the time. The dry end time curing time are related to the ambient temperature of the curing agent consumption construction, have nothing to do with the film thickness; the construction ground temperature should be higher than 5 ℃; the construction road surface must be dry clean, especially in rainy days, the road surface must be dry before construction;

When it is painted on the road section, it is used to separate the traffic flow in opposite direction; when it is painted on the roadside curb, it is used to prohibit the vehicles parking on the roadside for a long time temporarily. When the solid line is drawn in the road section, it is used to separate the opposite traffic flow; when it is drawn on the roadside curb, it is used to prohibit the vehicles parking on the roadside for a long time, dotted line.
