In the maintenance of municipal transportation facilities, the clarity and accuracy of road markings are crucial. However, with the passage of time and frequent crushing by vehicles, road markings will gradually wear out or become blurred and need to be re-striped. In order to ensure that there is no confusion between the new markings and the old ones, the complete removal of the old markings becomes a top priority in marking maintenance. The following will introduce the classification of road marking removal machine, use and how to choose, in order to help users better solve the problem of old marking removal.
The classification of the road marking removal machine
Road marking removal machine is mainly divided into the following categories according to its working principle and different application scenarios:
- Thermal fusion old marking line removing machine: this kind of equipment utilizes the grinding head made of cemented carbide, which is driven by the engine and operates at high speed, and grinds with the convex line on the road surface through the rotating centrifugal action, so as to completely remove the old marking line. Hot melt old marking removal machine is the ideal equipment for removing old hot melt marking on highways and city roads, with the advantages of simple operation and maintenance, good grinding performance and fast speed. However, it should be noted that the use of this equipment may cause different degrees of road damage, and often lead to a certain number of marking residue.
- Sand blasting road marking line remover: by controlling the type and particle size of sand blasting, this equipment can achieve different removal effects. It is more effective in removing the marking lines at room temperature and in the grooves of rough pavement. However, sandblasting is prone to generate a large amount of dust, so the work should be connected to an external vacuum cleaner to realize dust-free construction. Sandblasting type pavement marking removal machine walking speed is slower, lower efficiency, commonly used in small workload, less traffic flow of the road.
- Brush rubbing marking line removing machine: this kind of equipment through the power and transmission device drives the steel wire brush disk, rejecting the adherents of the work surface. According to the different devices and working principle, brush and wipe removal machine can be divided into heating type, thixotropic and round-trip type three. Heating type brush to remove the original marking line before removing the marking line for heating treatment, to be softened by the marking line and then use the steel wire brush disk to remove it; thixotropic brush to remove the work before removing the surface of the marking line brushed with a layer of thixotropic paint remover, so that it and the marking of the paint to produce full contact, dissolution, skinning, softening, separating, peeling, and other physical and chemical changes, and then use the steel wire brush disk on the marking of the marking line to be removed; Round-trip brush removal is by adjusting the pressure of the spring acting on the steel wire brush disk, so that the steel wire brush disk driven by the power unit to do round-trip movement on the work surface, so as to achieve the removal effect.
- High-pressure water jet road marking removal machine: this equipment uses high-pressure water to remove the old marking, applicable to large areas or highway marking removal work. High-pressure water jet road marking removal machine has the advantages of high removal efficiency, small damage to the road surface, but the cost is relatively high.
- Special airport glue removal truck: this kind of equipment is specially designed for airport runway and other special places, used for removing glue marks and old markings on the runway. Specialized airport deglossing trucks are characterized by high efficiency, precision, low damage and so on.
The use of road marking line removing machine
Road marking line remover is mainly used in the following scenes:
- Urban road maintenance: in the city, road markings often need to be updated and adjusted. The use of road marking removal machine can be quickly and effectively cleaned to ensure that there is no confusion between the newly drawn markings and the old markings.
- Highway Maintenance: Markings on highways also need to be updated regularly. Equipment such as hot melt old marking removers can be used to efficiently remove old markings in preparation for re-striping.
- Parking Lot Management: Parking lots need to be cleaned of parking lines and other markings on a regular basis. Using a road marking removal machine can quickly complete the sweeping work and improve the efficiency of parking lot management.
- Airport Runway Maintenance: Gum marks and old markings on airport runways need to be removed on a regular basis. The use of special airport glue removal trucks and other equipment can ensure the safety and tidiness of the runway.
How to choose the road marking removal machine
When choosing a road marking removal machine, users need to consider the following factors:
- Removal effect: the removal effect is the primary consideration in the selection of road marking removal machine. Users need to ensure that the selected equipment can completely remove the old marking, to avoid confusion with the subsequent new marking.
- Applicable scenarios: users need to choose the right road marking removal machine according to the actual work scene. For example, when removing lines in a small area in the city, you can choose alloy knife/steel brush type road marking removal machine; when removing lines in a large area or highway, you can choose high-pressure water removal truck or thermal fusion old marking removal machine.
- Cost-effectiveness: Users need to consider the cost-effectiveness of the selected equipment. Including the purchase cost of the equipment, the use of costs (such as fuel consumption, maintenance costs, etc.) and the service life of the equipment. When choosing, the user needs to weigh these factors to ensure that the selected equipment has a reasonable cost-effective.
- Ease of operation: Users need to consider the ease of operation of the equipment. Choose easy to operate, easy to maintain the equipment can reduce the operator’s labor intensity, improve work efficiency.
- After-sales service: users also need to consider the after-sales service of the equipment. Choose a good after-sales service brands and manufacturers, can ensure that in the process of use to get timely technical support and maintenance services.
