Marking cleaning may protect against mechanical runout. The heavier the better, the micro surfacing construction, the progressive way of self staggered cement asphalt pavement, expressway bridge deck and bridge, the pavement milling machine in the cleaning of the marking, the milling width of 250-300mm, the more the number of old aerial innovation machines, the higher the milling depth and the higher the adherence. Self weight of the machine. bend. The better the cleaning and milling of marking line. The starting threshold electric starting has obtained a rough appearance with high argument coefficient from scratch. To clear the airport route marking, the primary martial arts objectives of the milling machine are as follows: 230Kg deep and shallow recuperation calm recuperation jet, whose medium is no longer limited to water, should be strictly defined as liquid jet. If you cut foods containing sugar, water will easily dissolve sugar and destroy these foods. To avoid this defect, vegetable oil or other edible oil should be used as the medium for foods such as cut cakes and chocolates. Some jet applications also require emulsion as a medium. However, we generally say that water jet does not affect the existence of other liquid jets. The actual water jet can be divided into three types: continuous jet, pulse jet and cavitation jet. The use of garnet sand blasting abrasive can be more rapid and effective because of its high hardness, abrasion resistance and sharp corners. After adding garnet sandblasting abrasives to the water jet, not only the water pressure can be reduced, but also the friction force can be greatly increased. The effect will be better. Second, green and environment-friendly construction is convenient. With the use of high-pressure water jet cleaning technology and the addition of garnet sandblasting abrasives, it can not only be constructed at any time without the influence of time, but now with the development of technology, there are also good equipment that can be moved easily. Green environmental protection changes at any time to achieve a variety of cleaning purposes.

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.
