Where can the road shot blasting machine be used?
Anti-corrosion coating of steel bridge deck: In our country, the application of shot blasting technology in anti-corrosion coating of steel bridge cannot be denied. Most of the bridges under construction and already built will choose to use shot blasting to clean and roughen the surface before applying anti-corrosion primer or other spraying. The shot blasting machine used in Qingdao Cross-Bay Bridge, shot blasting process to treat steel bridges The surface can meet the steel plate cleanliness requirements of SA2.5/SA3, and the roughness can be controlled to meet the user's coating requirements. The entire process is dust-free and easy to move. It is environmentally friendly and convenient.
Tunnel maintenance: In my country, cement concrete is generally used for the pavement in the tunnel due to considerations of waterproofing and material resistance to fire and oil. But this also puts forward higher requirements on the anti-skid performance of the long tunnel pavement. For the above two problems that are still difficult to solve in our country, the shot blasting process is an environmentally friendly treatment method that is simple in construction, small in equipment investment, and effective. In the waterproof pavement of concrete bridge decks, the shot blasting process is already a requirement of the European and American technical specifications, and is gradually being accepted in China. The shot blasting process is used to maintain the concrete pavement.
Preventive maintenance of airport runways: The use of pavement shot blasting machines makes it easy to remove tire tracks and markings on concrete and asphalt runways. Tire removal (in addition to rubber), removal of markings, restoration and increase of the surface roughness of the airport runway, and improvement of the friction coefficient of the runway are all within the processing range of the road shot blasting machine. And in the processing process, the road shot blasting work is carried out in an orderly manner.
Municipal roads and paved roads: all kinds of road paving in the city can be cleaned by shot blasting machines to remove road signs and markings. At intersections with heavy traffic, the road can be roughened to improve the roughness and friction of the road. coefficient. Reduce problems in road construction. Therefore, the auxiliary role of the road shot blasting machine for urban construction is gradually standardizing and facilitating our lives.
