Deep Applications of Shot Blasting Machines in the Construction Industry
I. Core Application Scenarios
Concrete Waterproofing Pretreatment
Building Roofs: Areas exposed to rainwater, such as garage roofs and terraces, require shot blasting to remove surface laitance and oil stains, enhancing the adhesion of the waterproofing layer.
Underground Structures: Basement floors, side walls, and other areas prone to water seepage; shot blasting improves concrete density, reducing the risk of future leaks.
Construction Surface Cleaning
Newly Poured Concrete: Removes formwork residue and release agents, ensuring the bonding strength of subsequent coatings or paving materials.
Old Concrete Renovation: When repairing damaged road surfaces, shot blasting removes the aging layer, restoring the structural load-bearing capacity.
II. Technical Advantages
High-Efficiency Cleaning: Utilizes high-speed shot impact to remove surface impurities in one pass, achieving 5-8 times the efficiency of manual grinding.
Deep Treatment: Adjustable shot blasting intensity achieves a uniform roughness of 0.1-3mm, meeting the construction requirements of different waterproofing materials.
Environmentally Friendly and Energy-Saving: No chemical pollution, dust recovery rate exceeding 95%, meeting green construction standards.
III. Pathways to Enhance Industry Recognition
Case Study: A commercial complex project extended the lifespan of its roof waterproofing from 5 years to 15 years through shot blasting.
Process Optimization: Combining automated navigation technology, it achieves full coverage of large building rooftops, reducing labor costs by 30%.
Standardization: Participated in the drafting of the "Technical Specification for Waterproofing Base Treatment of Buildings," promoting industry technological upgrades.
Further Considerations: With the popularization of prefabricated buildings, the demand for surface treatment of precast concrete components is surging; shot blasting technology may become a standardized process.
