In modern transportation system, convex line, as an efficient and safe traffic facility, has been widely used in international developed countries. This unique traffic sign has become an important tool to enhance road safety with its remarkable shape design and excellent performance.
Features and Functions of Convex Line Marking
Convex lines are designed with a concave-convex structure, and the height between the base and the protruding part is usually controlled between 5-7 millimeters. This design not only gives the marking line excellent resistance to pollution, flexibility and alkali resistance, but also ensures its high whiteness, abrasion resistance and weather resistance. Even under adverse weather conditions, such as rain or night, the convex lines maintain a strong reflective effect, providing clear and unambiguous instructions to motorists. Their service life is usually up to 5-6 years or more, which greatly reduces maintenance costs.
Key Features of Convex Line Marking Include:
- Anti-skid performance: On curves or slippery roads, convex lines can effectively increase friction and prevent vehicles from skidding, ensuring driving safety.
- Vibration reminder: when the driver’s attention is not focused due to fatigue, the vehicle pressure over the convex line will produce obvious vibration and noise, waking up the driver in time to avoid potential accidents.
- Deceleration reminder: In toll plazas, turning points and dangerous roads, convex lines can effectively remind drivers to slow down and reduce the risk of accidents.
- Rainy Night Reflective: Even in the rainy night under the dim light conditions, the convex line can still maintain the reflective effect, ensuring that drivers can clearly recognize the road signs.
Convex Line Thermoplastic Road Marking Machine
The application of convex lines relies on specialized machinery – the convex line thermoplastic road marking machine. This machine creates raised structures on the road surface by spraying paint and utilizing the natural reflux of the paint or a specific process. Depending on the construction needs, convex line marking machines can be divided into various types such as hand-held convex line marking machines and self-propelled convex line marking machines, which are suitable for highways, urban expressways and other road sections that require mandatory deceleration.
The application of convex line marking machine is relatively specialized, but the overall investment cost is not high, and it can be flexibly selected according to different geographical environment and traffic flow. Its precise marking capability ensures the quality and effect of convex line marking, which further enhances road safety.
Problems and Solutions for Thermoplastic Convex Line Markings
Although convex lines have many advantages, in the actual construction, thermoplastic convex lines sometimes appear convex not shaped, convex height is not enough and other problems. These problems are mainly caused by the following reasons:
- Material temperature is too high: too high a coating temperature will lead to bulge molding is not ideal. The solution is to lower the heat, add raw materials and mix evenly, and wait until the temperature of the paint is lowered before construction.
- Mixing of other flat materials in the paint: In order to reduce the cost or improper construction, mixing of other flat materials in the paint will lead to reduced molding effect. The solution is to make sure that there is no residual coating in the hot melt kettle after each use, and clean the kettle before use.
- Equipment: Improper commissioning or malfunctioning of equipment may also lead to insufficient height of projection. The solution is to debug the road marking machine before construction to ensure that the equipment meets the predetermined standards before marking.
