Precautions for using hot melt marking coatings
1. When adding materials to the handcart, a filter should be used to filter to prevent impurities from entering and causing scratches on the markings
2. The construction temperature is around 180 ℃, and the applicable temperature is between 170 ℃ and 210 ℃
Prolonged heating above 3.200 ℃ can cause some components to evaporate and affect the quality of the coating
Above 4.230 ℃ can cause coating to burn, cause discoloration, and affect coating quality
When using the bottom coating agent, it is necessary to wait until the bottom coating agent is dry before applying, otherwise it may cause the marking to bubble and fall off
6. Construction on cement pavement should use a special undercoating agent for cement pavement
7. Before construction, the road surface should be cleaned and kept clean
During construction, the road surface must be kept dry. Avoid construction after exposure to dew, fog, and rain
9. Construction on cement pavement after rain must wait until the surface and base layers of the pavement are completely dry before proceeding
10. There should be no oil stains on the road surface. When oil stains appear, the road surface should be polished and treated
11. When the road surface is too smooth, it should be polished
12. When covering old wires, polishing treatment should be carried out
13. When covering the old line, it is necessary to use a special undercoating agent for cement pavement
14. Reflective glass beads should be embedded in 2/3 of the markings and exposed by 1/3 of the markings
