High-pressure roughing machines are essential surface treatment equipment in construction, primarily used to roughen surfaces like concrete and brick walls to enhance the adhesion of subsequent coatings (such as tile adhesives and waterproofing materials). The following is an analysis of their specific applications and advantages:
I. Application Scenarios
Wall Roughing
Applicable for roughening concrete and masonry walls, providing a better bonding surface for tile laying, plastering, or waterproofing.
It replaces traditional manual roughening with higher efficiency and improved surface uniformity.
Floor Anti-Slip Treatment
Roughening concrete floors increases the roughness and improves their anti-slip properties. It is commonly used in areas such as garages, ramps, and industrial workshops.
Renovation of Existing Surfaces
In renovation or restoration of existing walls, it removes existing coatings or smooth surfaces to ensure a secure bond for new materials.
Special Structural Treatment
Surface treatment of concrete structures such as bridges and tunnels, preparing for the application of waterproofing or anti-corrosion coatings.
II. Core Advantages
High Efficiency and Energy Saving
Mechanized operation speed far exceeds manual labor, with a single unit capable of processing hundreds of square meters per day.
Compared to sandblasting or milling equipment, it consumes less energy and produces no dust.
Precise and Controllable
By adjusting parameters such as pressure and speed, the roughening depth and texture can be controlled to suit different construction requirements.
Safety and Environmental Protection
No chemical pollution, low noise and vibration, meeting modern green construction standards.
Cost Savings
Reduces labor costs and material waste (e.g., eliminating the need for additional primer).
III. Construction Precautions
Substrate Assessment
Before construction, check the substrate strength to avoid roughening loose or cracked areas.
Parameter Adjustment
Select the appropriate pressure (typically 50-200 MPa) and tool type based on the hardness of the substrate.
Safety Protection
Operators must wear protective equipment (such as goggles and dust masks), and the equipment must be maintained regularly.
Post-processing
After roughening, debris needs to be cleaned and, if necessary, a primer should be applied to further enhance adhesion.
IV. Comparison with Other Equipment
Compared to traditional manual roughening: Efficiency is 5-10 times higher, and the texture is more uniform.
Compared to high-pressure water jets: More suitable for dry environments, no wastewater treatment is required.
