The advantages of stone shot blasting machines
Shot blasting treatment of stone with shot blasting machines is an efficient and environmentally friendly surface treatment process, which has the following significant advantages:
1. Efficient and uniform surface treatment
High-efficiency cleaning: The stone shot blasting machine can quickly remove the oxide layer, stains, old coatings or burrs on the surface of the stone by high-speed ejection of metal shot (such as steel shot, stainless steel shot), significantly improving the processing efficiency.
Uniformity: Shot blasting treatment can cover the complex surfaces and crevices of stone, achieving uniform treatment and avoiding local omissions that may occur due to manual or traditional grinding.
2. Enhance the physical properties of stone materials
Enhance adhesion: The surface of the stone after shot blasting forms a uniform roughness (" anchor pattern effect "), which is conducive to the adhesion of subsequent coatings, adhesives or protective agents, and extends the service life.
Stress relief: It can alleviate the microscopic stress on the surface of stone, reduce the risk of cracking, and is especially suitable for brittle stone.
Strengthen surface hardness: Slightly compress the surface layer of the stone to enhance wear resistance and fatigue strength.
3. Environmental protection and energy conservation
No dust pollution: Stone shot blasting machines are usually equipped with dust removal systems that can collect the debris and dust generated by shot blasting, avoiding air pollution caused by traditional dry grinding.
Recycling pellets: Pellets can be recycled and reused, reducing material waste and costs.
No chemical reagents required: It is a physical treatment method, avoiding the pollution to the environment caused by chemical methods such as acid washing.
4. Strong adaptability and multi-functionality
Processing irregular-shaped stones: Suitable for various forms such as flat plates, reliefs, and irregular-shaped stones, and can even handle the complex textures of stone sculptures.
Diversified effects: By adjusting the material, size and injection parameters of the shot, different roughness or texture effects (such as antique, matte, anti-slip, etc.) can be achieved.
Compatible with various stones: It can be used for marble, granite, artificial stone and many other materials.
5. Reduce labor costs and ensure operational safety
The stone shot blasting machine has a high degree of automation: it reduces the reliance on skilled workers and lowers the labor intensity of manual labor.
Safety improvement: The closed operation of the stone shot blasting machine reduces direct contact of personnel with dust and debris, lowering the risk of occupational diseases (such as silicosis).
6. Improve the aesthetic appeal and functionality of stone materials
Uniform appearance: Eliminate color differences and surface defects to make the color of the stone more uniform and natural.
Anti-slip treatment: The stone shot blasting machine enhances the anti-slip performance of stone floors through controllable roughening treatment, making it suitable for outdoor squares, staircases and other scenarios.
Retro effect: It can simulate the natural weathering effect and meet the design requirements of ancient-style buildings.
7. Economic advantage
Low long-term cost: Although the initial investment in equipment is relatively high, efficient processing and low consumption of consumables can reduce long-term operating costs.
Reduce rework: Uniform processing effect reduces the probability of subsequent repairs or repeated processing.
Application scenario example
Building exterior wall and floor stone: Enhance anti-slip performance and anti-aging ability.
Monuments and carvings: Clean the surface and enhance texture details.
Stone restoration project: Remove old coatings or stains to restore the original appearance of the stone.
Precautions
Stone type selection: For softer stones (such as limestone), the shot blasting intensity should be controlled to avoid excessive damage.
Parameter optimization: The shot speed, density and processing time need to be adjusted according to the hardness of the stone and the target effect.
Subsequent protection: It is recommended to apply a protective agent promptly after shot blasting by the stone shot blasting machine to prevent stains from seeping into the rough surface.
Shot blasting for stone treatment is an advanced process that integrates high efficiency, environmental protection and multi-functionality. It is especially suitable for stone projects with high requirements for surface quality and functionality, and can significantly enhance the practical value and aesthetic appeal of the stone.
