How to clean the traffic road markings and what can be cleaned?

Time: April 10, 2020 09:33 source: unknown author: admin

  When the road, airport and expressway markings are re planned or repaired, the original markings need to be removed because the road markings are usually painted with paint or hot-melt resin materials. If the old and new pavements are not cleaned, the slippage of the new and old pavements is easy to cause instability of the structural layer and affect the engineering quality, or the appearance of the old markings in the dark and humid environment will mislead the drivers and affect the traffic.
There are three traditional cleaning methods. The first method is painting. Black paint is applied on the old marking line. This method is applicable for a short time. The second method is grinding and milling machine. This method is suitable for thin hot-melt marking. After cleaning, the pavement will leave obvious marks, which is easy to damage the original pavement and increase the maintenance cost. The third is chemical cleaning, this method is not thorough cleaning, easy to cause pollution to the environment, not safe enough. The cost of the tools used in these traditional methods is low, but the labor cost is high and the efficiency is low. It is easy to cause damage to the road surface, increase the maintenance cost of the road, and even cause certain interference to the traffic.
  High pressure water jet cleaning The method is a new method widely used

 
This kind of high-pressure water pump imported from Germany can work continuously for 24 hours. Using the impact force of pure high-pressure water, it is not only environmental protection, high efficiency, but also simple and safe operation. It can accurately control the cleaning direction and has high flexibility. It can quickly and thoroughly clear the sign lines on highways, roads and aircraft runways, without damaging the original road surface and producing garbage. It is also suitable for high pressure cleaning, engineering cleaning vehicles and road surface cleaning in Chinese market, and can also be used with cleaning system.
Due to the influence of working environment, the high pressure water line marking cleaning machine is suitable for diesel engine driven or gasoline driven. Although using the principle of high-pressure water jet to clear road markings has many advantages, but the selection of equipment is also very important. The moving speed of high-pressure water road marking cleaning machine is not easy to be too fast. Generally, when the mark line is about 1 mm, the moving speed is 330 M / s when the equipment pressure is 900 bar, and the cleaning distance is suitable to be about 27 mm. When the equipment pressure is 1100 bar, the distance is suitable to be about 26 mm. Therefore, the parameter selection of high-pressure water marking cleaning machine should be determined according to the requirements of efficiency. If the efficiency requirements are high, the equipment with relatively large parameters should be selected. If there is no special requirement for efficiency, the equipment with small parameters can be selected, and the procurement cost will be lower.
