Can the road shot blasting machine clean the road markings?
Due to changes in traffic management plans and other reasons, it is often necessary to remove the original road markings. If the original markings are not completely removed, it is easy for the driver to think that the old markings still exist under night lights or in a humid environment, which will mislead the driver's driving and is very detrimental to driving safety and traffic control; on the other hand, although some marking removal methods can remove the markings cleanly, they will damage the road surface, affect the road landscape, and increase the road maintenance cost. At the same time, considering that different road marking removal methods have different impacts on traffic, the required operation time, and the degree of environmental impact; therefore, it is very important to choose a suitable road marking removal method.
The working principle of the shugong series of road shot blasting machines is: the motor drives the impeller body to rotate, and the shot blasting machine, relying on the centrifugal force, throws the shot (steel shot or sand) onto the working surface at a very high speed and a certain angle, allowing the shot to impact the working surface, and then the airflow of the matching vacuum cleaner is cleaned inside the machine, and the shot and the impurities and dust removed are separated and recovered. The recovered shot is repeatedly circulated to achieve the purpose of cleaning the road markings. When the shot blasting machine is operated, the shot blasting flow rate is controlled by controlling and selecting the particle size and shape of the shot, adjusting and setting the walking speed of the machine, and obtaining different shooting intensities and different surface treatment effects.
Shot blasting machines can be divided into hand-push type, vehicle-mounted type and white-travel type according to the walking mode. Shot blasting cleaning method is mainly used for cleaning the markings of cement concrete pavement, especially suitable for cleaning the markings at room temperature.
Its characteristics are that the friction coefficient of the marking road surface after shot blasting cleaning will increase, which is beneficial to driving safety, and no large amount of dust will be generated during the cleaning operation, which is especially suitable for the removal of old lines near the sidewalks on urban roads.
