During the construction of reflective the Best reflective hot melt marking paint Manufacturers china for expressway, problems such as discoloration and poor reflective effect at night may occur, which seriously affect the construction quality of the Best reflective hot melt marking paint Manufacturers china. Based on years of understanding of the construction of the Best reflective hot melt marking paint Manufacturers china, this paper briefly summarizes and analyzes various problems often encountered, and gives suggestions to solve them.

Discoloration of the Best reflective hot melt marking paint Manufacturers china

High temperature, scorching at the bottom of the hot-melt kettle, unqualified product quality and coating deterioration during the melting process of hot-melt coating may cause discoloration. Therefore, during the construction process, the quality of the coating shall be strictly tested, the heating temperature shall be well controlled, and the hot melt kettle shall be cleaned before the coating is melted.

Poor reflective effect of the Best reflective hot melt marking paint Manufacturers china

If the reflective effect of the Best reflective hot melt marking paint Manufacturers china on expressway is poor, the reflective effect of marking at night is not obvious. It is mainly caused by the following reasons: uneven distribution of glass beads, more impurities in pre mixed and surface scattered glass beads, poor particle size distribution, low viscosity of paint, poor mobility, and uneven pavement. During the trolley construction, the spreading speed of glass beads shall be controlled, and the qualification inspection of construction materials shall be strengthened. If the road surface is not normal, the construction personnel shall have a high level of construction technology. Only in this way can the impact of road surface marking construction be minimized.

Cracks in the Best reflective hot melt marking paint Manufacturers china

Crack is also a common quality problem in the construction of the Best reflective hot melt marking paint Manufacturers china. During construction, the ambient temperature is relatively low, and the coating shrinks when cooled; Uneven settlement of subgrade, material expansion or contraction; The mismatch between the hardness and softness of the coating and the pavement, and the softening of the pavement under the impact load may lead to cracks in the markings. Therefore, in the actual construction process, the hot-melt coating and coating proportion shall be reasonably selected according to the specific construction time. If the cracks caused by the subgrade cannot be avoided, the quality control of subgrade construction can only be strengthened.

Peeling of the Best reflective hot melt marking paint Manufacturers china

If the road surface is not cleaned and no lines are drawn for a long time after the application of the primer, the surface of the primer will be contaminated with a lot of dust; During construction, the road surface is wet and not dry enough, the paint is not fully melted, the undercoat is not properly selected, and the ambient temperature is relatively low, which may lead to peeling and peeling of the Best reflective hot melt marking paint Manufacturers china. In addition, the pavement fracture is also prone to peeling. Therefore, in the specific construction process, the paint formula should be reasonably selected to ensure that its flexibility and adhesion meet the construction requirements, and the operation should be strictly in accordance with the construction process to ensure that the pavement is clean. After the application of the primer, it is necessary to draw lines immediately to avoid dust contamination. Construction cannot be carried out when the road is wet. If the construction period is tight, manual drying can be used. When the coating is heated, it must be fully stirred to ensure its complete dissolution. The primer can be reasonably selected according to the actual situation of the road to ensure good adhesion.
