In the construction of municipal road markings, the flowability of hot-melt coatings directly affects the flatness and construction efficiency of the markings. Insufficient liquidity can lead to rough edges, uneven thickness, and even problems such as broken lines and pockmarks on the marking lines. TOP ROAD Transportation Technology Co., Ltd. has been deeply involved in the field of road marking for many years. With rich research and development experience and technological accumulation, it provides high-performance hot-melt coatings and professional solutions for municipal engineering. The following are the mobility improvement techniques summarized in the practice of municipal marking teams to help you efficiently complete construction tasks.
First move: precise temperature control to avoid overheating or undercooking
The fluidity of hot melt coatings is extremely sensitive to temperature. When the temperature is too low, the coating is not completely melted and has poor fluidity; Excessive temperature can easily lead to resin aging and viscosity increase. During construction, the temperature of the hot melt kettle needs to be dynamically adjusted according to the type of coating and ambient temperature
Preheating stage: Heat slowly with low heat first, gradually increase the temperature after the coating has initially melted, to avoid local overheating.
Construction process: Keep the material temperature stable, regularly use a temperature gun to detect the actual temperature at the discharge port, and ensure that the coating is in the best flow state.
TOP ROAD’s hot melt coating adopts a heat-resistant resin formula, which has a wide temperature adaptability range and can maintain excellent leveling performance in complex environments.
Second move: Equipment maintenance and process optimization
The cleanliness and operation process of construction equipment directly affect fluidity:
Clean the hopper and pipeline: Thoroughly clean the residual paint on the equipment after daily construction to avoid clumping and blocking the discharge outlet. The paint adhered to the edge of the rear scraper should be removed in a timely manner to ensure uniform discharge.
Adjust construction speed: For coatings with poor fluidity, reduce the trolley speed and give the coating sufficient leveling time; If high-speed construction is required, TOP ROAD high flow grade products (such as vibration specific materials) can be selected to balance efficiency and molding effect.
Avoid repeated heating: Prolonged insulation of the remaining coating will cause coking and thickening. It is recommended to add materials as needed to reduce the number of times it needs to be reheated.
Third move: Scientific selection of materials and formula adaptation
Different road surfaces and climate conditions require coatings with different characteristics:
Newly constructed asphalt pavement: Choose high resin content coatings to improve adhesion and leveling, and avoid coating shrinkage caused by high road surface oiliness.
Low temperature environment: Choose a winter specific formula and add low-temperature flow additives to prevent premature solidification.
Customization requirements: TOP ROAD supports customizing formulas according to customer construction scenarios, such as adjusting the particle size distribution of fillers or adding leveling agents to significantly improve fluidity.
