Gasoline Cleaning: Efficiently Removes Oil Stains, Ensuring Road Safety
On highways, fuel leaks, oil seepage, or oil pollution caused by accidents are common problems. These oil stains form a smooth film, significantly reducing the road surface friction coefficient and increasing the risk of vehicle skidding, especially in rainy weather or on curved areas. Mobile shot blasting machines play a key role in this process:
Technical Principle: The equipment uses a high-speed rotating impeller to propel steel shot at 60-80 meters per second onto the oil stain surface. The impact force of the steel shot breaks and peels off the oil film, while friction removes deeply penetrated contaminants. The entire process is a dry operation, and with a built-in dust collection system, 99% of the steel shot and oil dust can be recovered, avoiding secondary pollution.
Practical Application: In highway maintenance, operators drive mobile shot blasting machines along accident-prone sections (such as toll stations and service area exits). For example, when dealing with diesel spills, a single shot blasting operation (parameters: shot size 0.8-1.2mm, treatment depth 1-3mm) can clean a 100-square-meter area within 10 minutes. Compared to traditional high-pressure water guns or chemical cleaning, mobile shot blasting machines are more environmentally friendly, efficient, and do not damage the asphalt base layer.
Core Benefits: Improves road surface skid resistance by 30%-50%, reduces traffic accidents caused by oil spills; extends road surface life, and avoids premature aging caused by oil corrosion. Statistics show that in a section of the Shanghai-Kunming Expressway, this technology reduced maintenance costs by 20%.
Marking Cleaning: Precisely removes old markings, optimizing traffic guidance. Old traffic markings on highways (such as lane lines and turn arrows) need to be removed due to long-term wear or construction changes. Traditional methods such as grinding or using chemical solvents are inefficient and leave many residues, while mobile shot blasting machines offer a revolutionary solution:
Technical Principle: A beam of steel shot is directed and precisely strikes the marking material (hot melt paint or cold paint), shattering it into powder through a micro-explosion effect. The equipment allows for adjustable shot blasting angle and intensity (e.g., 30-60 degree incident angle) to ensure that only road markings are removed without damaging the road surface structure. An integrated dust collection system collects debris in real time, keeping the work area clean.
Practical Applications: In highway reconstruction and expansion projects or road marking renewal projects, mobile shot blasting machines operate in a "go-and-clean" mode. For example, in the Beijing-Hong Kong-Macau Expressway maintenance project, one machine cleaned an average of 5 kilometers of old road markings per day, taking only one-third the time of manual labor. During operation, a GPS positioning system achieves millimeter-level precision, avoiding accidental damage to adjacent road surfaces.
Core Benefits: A removal rate of over 95%, providing a "blank slate" for repainting road markings; improved construction safety and reduced road closure time; significant environmental advantages, with no chemical solvent evaporation. Actual case studies show that after application on the Guangzhou-Shenzhen Expressway, road marking renewal efficiency increased by 40%, and driver feedback indicated improved clarity.
Anti-skid treatment: Enhancing the coefficient of friction and preventing accident risks. Slippery sections of highways (such as bridges, ramps, or areas affected by rain or fog) are high-risk areas for accidents, and anti-skid treatment is directly related to driving safety. Mobile shot blasting machines use surface roughening technology to create a durable texture, effectively improving anti-skid properties.
