Markings removal 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. Or by adding liquid medium to the abrasive, the dust pollution during sand blasting can also 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. Shot blasting cleaning method Shot blasting cleaning method is to remove the marking line through shot blasting equipment.

1. Its working principle is: the motor drives the impeller body to rotate, and the marking is removed by centrifugal force. The shot blasting machine shoots the shot (steel shot or sand grain) onto the working surface at a high speed and at a certain angle, so that the shot can impact the working surface. Then, the air flow of the supporting vacuum cleaner is used to clean the inside of the machine to separate the shot and the cleaned impurities and dust, and the recycled shot is repeatedly shot, So as to achieve the purpose of clearing the pavement markings.

2. 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 by the nozzle. During the operation of the shot blasting machine, different shot strengths can be obtained by controlling and selecting the particle size and shape of the shot, and adjusting and setting the walking speed of the machine to control the shot flow of the shot, Obtain different surface treatment effects.

3. The shot blasting machine can be divided into manual type, vehicle mounted type and white line type according to the traveling mode. Shot blasting method is mainly used for the cleaning of cement concrete pavement markings, especially for the cleaning of normal temperature markings. The marking removal can achieve different cleaning effects by selecting different sandblasting media, and sandblasting is applied in machinery manufacturing, industrial production, road maintenance and other fields.

4. On average, a passenger marking machine can construct 10 kilometers per hour, while a manual marking machine can work 8 hours a day to construct 5-6 kilometers. Take a 100km highway for example. It takes a day to work a little overtime with the driving marker. Of course, this is ideal. The actual construction of the marker may take more time, so we can extend it for three days; However, the traditional hand propelled marking machine wants to complete the 100km marking project in three days, even if five hand propelled marking machines are used together to work overtime at full power.
