Municipal Road Marking and Construction Requirements of Road Dashing
July 15, 2023
The main role of road traffic markings is to pass rules, warnings and guidance on traffic in relevant roads. The road traffic markings are mainly set on the road surface, are exposed to the sun, rain, and snow, and are subject to the impact abrasion of vehicles. Therefore, their performance is strictly required. The following municipal roads in Foshan are underlined for the construction of road-scoring.
The application of room-temperature acrylic acid marking paint is poor, and it cannot be constructed below 5°C. Due to the high flux content, it poses a fire hazard to construction. The adaptability of hot-melt marking construction is also poor, and it requires construction above 15°C. If the construction is under high temperature, the cooling time will be long, and the glass beads will easily sink, which will affect the traffic and reflective effects. If the construction is conducted at low temperature, the cooling will be too fast, the coating cannot effectively penetrate the ground, the adhesion force will decrease, and the glass beads will be reduced. Unusable sinks can easily fall. Liquefied gas is also required to be heated to a high temperature of 200°C, posing a blasting and fire hazard to the construction. The two-component road marking paint is a cold-formed commodity and has excellent construction applicability. It is suitable for construction under the ambient temperature of -5 to 35°C. After artificially adjusting the amount of chemical catalyst added, it can be artificially different at different temperatures. Control the curing time; the construction process is semi-mechanized and highly efficient; the coating is virtually free of flux, non-flammable, and does not require heating, ensuring construction safety.
The hot-melt line in the construction of the floor paint is often used as a traffic route or a garage project. It has features such as high wear resistance, low quotation, and short construction time, so it is well received by many consumers. However, attention must be paid to the selected materials and temperature during the marking process. Due to the fact that errors often occur in these processes, the quality problems will be caused.
