Hot melt marking

Advantages: marble and other raw materials sampling is very easy, simple processing technology, simple engineering construction, non-stick tire time is short, can quickly open to the outside traffic travel; Wide range of application; Thickness 0.5-2.5mm, slightly thick; The inverse transmission coefficient is general; Low project cost; High cost performance; Service life is generally about 24 months.

Defects: by temperature difference harm, service life more cracks; The working ability of road marking glass beads is weak, the glass beads are very easy to fall down, and the early return light attenuation coefficient is faster; The project construction needs compressed natural gas heating, environmental pollution, consumption of resources; Maintenance project construction must be closed traffic travel, project construction efficiency, safety risk, great harm to traffic flow; It is difficult to clear the marking lines of old roads and the cost is high. During the application period, the glass beads and the ground abandoned road markings will move into the soil layer on both sides of the road with the precipitation, causing environmental pollution. In particular, the glass beads can hardly be dissolved, so the problem is serious in the long run.

Construction machinery and equipment: based on small and medium-sized hand push marking machine.

Solution type road markings

Advantages: low cost, simple and convenient construction, early conspicuous, good visual recognition, general mechanical automatic painting, high efficiency;

Defects: thin thickness, poor adhesion force, poor wear resistance; The cycle is short, generally 3 months; Does not return light; Heavy smell is not environmental protection, VOC pollution. Generally only in the municipal road application, not high speed national and provincial roads and other heavy traffic conditions.

Construction machinery and equipment: mechanical automation paint leading.

Two component road markings

Advantages: high inverse transmission coefficient; VOC consumption is small, environmental protection; Thin thickness 0.4-1.6 mm thinner; Good adhesion force between coating and ground, good wear resistance; The coating has strong adhesion to the glass beads, so it has good reflective performance. Can be shaped into a variety of structural forms; Maintenance project construction does not clean up the old line immediately cover, road marking solid layer bonding effect is very good; Can choose mechanical automation method, high efficiency, the effect is very good, less harm to traffic flow; Less fine particles in the air during the application period.

Defects: AB two components are prepared on the spot, the chemical change of soil, the construction team professional and technical personnel quality requirements are high; The dry and solid time is longer than that of the hot melt type, which is more harmful to the temperature. Special equipment is required, and the price of machinery and equipment is high; The price of road marking is higher;

Water-soluble road marking

Advantages: Relative to the two-component road marking can be understood as a single component, painting engineering construction is simple; Raw materials and the ground adhesion force is strong, high inverse transmission coefficient; Maintenance project construction does not need to clean the old line, can be coated immediately, road marking solid layer strong adhesion; Good environmental protection, the key alternative solution type road marking; Maintenance engineering construction can complete the car stop mechanical automation rapid engineering construction; Moderate price; Less exhaust emissions during the service life.

Defects: the construction of the natural environment is relatively high, dry and solid time is relatively long, adverse maintenance work; Wear resistance is weak; It can be used as a substitute for solution road marking or to restore the reflective performance of road marking.
