Shot blasting cleaning method Shot blasting cleaning method is to remove the marking line through shot blasting equipment. Its working principle is: the motor drives the impeller body to rotate. With the centrifugal force, the shot blasting machine shoots the shot (steel shot or sand) at a high speed and at a certain angle onto the working surface, allowing the shot to impact the working surface. Then, the machine interior is cleaned by the air flow of the supporting vacuum cleaner to separate the shot and the cleaned impurities and dust, and the recovered shot is repeatedly shot, So as to achieve the purpose of clearing the pavement markings.

1. During the operation of the shot blasting machine, the shot blasting flow is controlled by controlling and selecting the particle size and shape of the shot, adjusting and setting the walking speed of the machine, so as to obtain different shot blasting intensity and different surface treatment effects. The shot blasting machine can be divided into manual type, vehicle mounted type and white line type according to the walking mode.

2. Shot blasting method is mainly used for the cleaning of cement concrete pavement markings, especially for the cleaning of normal temperature markings. Sand blasting cleaning is a method of cleaning the surface with abrasive (shot glass bead, steel shot, steel sand, quartz sand, carborundum, iron sand, sea sand) propelled at a high speed through the nozzle. Different cleaning effects can be achieved by selecting different sand blasting media. Sand blasting is applied in machinery manufacturing, industrial production, road maintenance and other fields.

3. Sand blasting pavement marking remover can achieve different removal effects by controlling the type and particle size of sand blasting, which is more effective for the removal of markings in normal temperature markings and rough pavement grooves. Since a large amount of dust is easily generated during sand blasting, the external vacuum cleaner shall be connected to realize dust-free construction.

4. Or by adding liquid medium to the abrasive, the dust pollution during sand blasting can be reduced. In order to achieve a better cleaning effect, the sand blasting pavement marking remover is slow in walking speed and low in working efficiency, so it is often used for marking removal in sections with small workload and small traffic flow.
