Sandblasting deburring is a common surface treatment technology, which uses high-speed jetting of quartz sand or garnet sand to remove burrs, oxide layers, rust and other defects on the surface of metals, plastics and other materials, so as to achieve the purpose of surface purification. Among them, garnet sand is widely used in the field of sandblasting and deburring because of its moderate hardness, low cost and environmental protection.
First, the principle of sandblasting and deburring.
The principle of sandblasting and deburring is mainly to use high-speed jetting quartz sand or garnet sand to impact the surface of the material, and remove the burrs, oxide layer, rust and other defects through the impact, friction and pressure of the sand particles, and at the same time make the surface form a certain roughness and improve the adhesion of the surface.
Second, the characteristics of garnet sand.
Garnet sand is a natural mineral material with moderate hardness, low cost, and environmental protection, making it an ideal choice in the field of sandblasting and deburring. Compared with quartz sand, garnet sand has a higher hardness, which can better remove burrs and deep scratches, and at the same time, its density is larger, and the sand particles are easier to adhere to the surface, improving the efficiency and quality of deburring.
3. The application range of sandblasting and deburring.
Sandblasting deburring is widely used in the surface treatment of metals, plastics and other materials. In the field of metal processing, sandblasting and deburring can remove burrs, oxide layers and rust on the surface of steel plates, castings, steel pipes and other materials, improve the roughness and adhesion of the surface, and lay a good foundation for subsequent painting, welding, assembly and other processes. In the field of plastic processing, sandblasting and deburring can remove burrs and release agent residues on the surface of injection molded parts, extruded parts and other materials, improve the roughness and adhesion of the surface, and provide good surface conditions for subsequent painting, bonding and other processes.
Fourth, the process of sandblasting and deburring.
The process of sandblasting and deburring generally includes the following steps:
1.Pretreatment: Cleaning, degreasing, rust removal and other treatments on the surface of the material to improve surface adhesion and remove surface defects.
2.Sandblasting and deburring: The use of high-speed jetting of quartz sand or garnet sand to impact the surface of the material to remove defects such as burrs, oxide layers and rust.
3.Post-treatment: Clean, dry and other treatments on the treated surface to improve surface quality and adhesion.
4.Inspection and evaluation: The treated surface is inspected and evaluated to ensure that the desired treatment effect is achieved.
5. Quality control of sandblasting and deburring.
In order to ensure the quality and effect of sandblasting deburring, it needs to be controlled from the following aspects:
1.Selection of sand grains: According to the requirements of the treated surface and the characteristics of the material, select the appropriate sand type and particle size.
2.Control of spraying parameters: Reasonable control of spraying pressure, spraying distance, spraying angle and other parameters to ensure that the sand particles can evenly impact on the surface of the material.
3.Control of processing time: According to the condition of the material surface and the treatment requirements, the processing time is reasonably controlled to ensure the effect of removing burrs and oxide layers.
4.Environmental control: Keep the treatment environment clean and dry, and avoid the influence of dust and other impurities on the treatment effect.
5.Equipment maintenance: Regularly maintain and maintain the sandblasting equipment to ensure the normal operation and use of the equipment.
