Advantages of Road Surface Abrasive Blasting Machine
I. Construction Effect of Road Surface Abrasive Blasting Machine
The treatment depth is controllable, and the base surface quality standards are unified.
By adjusting the walking speed and abrasive flow of the road surface abrasive blasting machine, the grinding depth can be precisely controlled, and uniform and rough texture structures can be produced, improving the friction coefficient of the road surface; rust removal, removal of floating mortar, removal of markings, and sanding can be completed in one step. The roughness stability reaches the engineering specification requirements, providing strong adhesion for epoxy flooring, asphalt overlay, waterproof coating, and anti-corrosion layer, and eliminating peeling and detachment.
There is no unevenness or missed sanding, and the treatment is complete.
The road surface abrasive blasting machine moves straight, and the steel balls impact the ground vertically. The gaps, expansion joints, edges of the bridge deck, and other areas can be uniformly treated. There are no wave patterns or blind spots left by the grinding machine, and it will not damage the original structural strength of the base layer.
It does not damage the base layer itself.
Pure physical impact operation, only removing the surface rust, floating mortar, old markings, and aged asphalt of the road surface, without excessive cutting of the concrete / steel plate base layer. Compared with milling machines and angle grinders, it causes minimal damage to the road structure and is suitable for thin-layer treatment.
II. Environmental Protection and Dust-Free, Green Construction
It is equipped with a synchronous wind power recovery system.
Abrasive blasting and dust collection are carried out simultaneously, and steel balls and dust are immediately recovered. The construction road has almost no dust, and there is no need for barriers and water spraying to reduce dust. It does not pollute the surrounding air, green belts, and buildings.
There is no chemical pollution.
Different from acid washing and paint removers, the entire process is dry physical operation, without generating wastewater or chemical waste, no corrosion residue, and can be constructed in municipal roads, indoor garages, bridges, tunnels, and enclosed spaces.
Waste is automatically separated, and the steel balls are recycled and reused automatically. Dust, old paint chips, and concrete powder are collected centrally, and the waste is centrally removed. The site is clean and tidy.
III. Advantages of Construction Efficiency and Cost of Road Surface Abrasive Blasting Machine
Fast construction speed, significantly shortening the construction period
Small hand-pushed or electric road surface abrasive blasting machines operate continuously, with a handling efficiency far higher than handheld sanding machines and steel wire brushes. For large-scale construction on bridge decks, floors, and expressways, multiple machines can be connected and operated simultaneously.
The overall cost of consumables is low.
Steel ball loss is low, and it can be recycled thousands of times without frequent replacement of grinding wheels or sandpapers. One person can operate it, with less labor input, simple maintenance, and long lifespan of wear parts.
No need for secondary cleaning
Dust and waste are collected on the spot. After the construction is completed, there are no dust residues on the road surface, and the next process such as waterproofing, asphalt paving, and floor paint application can be carried out immediately, eliminating the need for cleaning and rinsing steps.
IV. Wide Application Scenarios and Strong Generalization of Road Surface Mobile Abrasive Blasting Machine
Multi-material road surfaces are applicable
Concrete road surfaces, asphalt road surfaces, steel bridge decks, steel structure box girders, tunnel floors, epoxy base surfaces of garages, airport runways, steel plates of bridges and docks, and stone floors can all be used.
Multi-functionality in one machine
It can complete various engineering operations: road surface sanding for anti-slip, removal of old hot-melt markings, steel plate rust removal for bridges, removal of surface oil and floating mortar, removal of carbon deposits in tunnels, texture repair for airport runways, and pre-treatment of floor bases.
V. Safety and Operation Advantages
Road surface mobile abrasive blasting machine is easy to operate and has a high safety factor.
It can automatically move without the need for large professional operation certificates. The sealed abrasive blasting bin does not cause steel balls to fly and will not injure pedestrians or damage surrounding facilities. It is safer for construction in indoor, underground, and enclosed spaces.
Flexible adaptation to narrow spaces
The small hand-pushed model is flexible in turning, and it can be used for construction on residential roads, garage parking spaces, bridge guardrails, narrow passages in tunnels, and small workshop floors. The large vehicle model is suitable for large-scale projects on highways and national roads.
VI. Compliance with Engineering Requirements
Meets all national construction requirements
The abrasive blasting treatment process is recognized by various construction specifications for roads, bridges, tunnels, airports, and waterproofing projects. The roughness and cleanliness after abrasive blasting are detected once and meet the standards, with a high acceptance rate.
Construction in low-temperature environments is possible. Waterless construction operations can be carried out normally even in low-temperature and sub-zero environments, without being affected by ice formation or drainage conditions of the site.
VII. Comparison of Road Abrasive Blasting Machine with Traditional Milling and Grinding Equipment
Milling machine: Cutting too deeply, damaging the base layer, generating huge dust; Abrasive blasting only treats the surface layer, protecting the pavement.
Angle grinder grinding: Low efficiency, uneven texture, severe dust emission; Abrasive blasting is carried out on a large area uniformly, without dust.
Chemical paint and line removal: High pollution, residual corrosion; Abrasive blasting is purely physical and environmentally friendly with no residue.
