Surface treatment sandblasting room plays a key role in creating a flawless surface protection barrier.1. Working principle of sandblasting roomSandblasting: Sandblasting room removes impurities such as scale, rust, stains, etc. on the surface of the workpiece by spraying abrasives (such as sand, glass beads, etc.) at high speed. It can also roughen the surface and improve the adhesion of the coating.Environmental protection: The sandblasting room is designed with a closed space and an efficient dust removal system to prevent abrasives and dust from spreading into the working environment, protecting the health of operators and the cleanliness of the working environment.2. Choose the right abrasiveAbrasive type: Choose the right abrasive according to the material of the workpiece and the processing requirements. For example, glass beads are suitable for light decontamination and surface finishing, while steel sand is suitable for heavy rust removal.Abrasive size: Abrasives of different sizes are suitable for different processing needs. Coarser abrasives have stronger removal ability, but may affect the surface finish; finer abrasives are more suitable for surface finishing.3. Controlling the spraying parametersPressure regulation: The spraying speed and force of the abrasive are controlled by adjusting the pressure of the compressed air to achieve the purpose of being both efficient and not damaging the surface of the workpiece.Distance control: The distance between the spray gun and the surface of the workpiece should be appropriate, usually kept between 10-30 cm. Too close may cause surface damage, and too far will result in poor treatment effect.4. Uniform treatmentMovement method: The operator should move the spray gun regularly to ensure that all parts of the workpiece surface are treated evenly to avoid omission or excessive spraying.Multi-angle spraying: For workpieces with complex shapes, spraying from multiple angles is required to cover all surfaces.5. Subsequent treatmentCleaning: After sandblasting, abrasives or dust may remain on the surface of the workpiece, which needs to be thoroughly cleaned to ensure the adhesion and protective effect of the coating.Painting preparation: The surface after sandblasting should be painted as soon as possible to prevent re-oxidation. If painting is not possible immediately, measures should be taken to protect the surface, such as using anti-rust oil.6. Quality controlSurface roughness detection: Use a roughness meter to check the surface roughness after sandblasting to ensure that it meets the painting requirements.Cleanliness inspection: Confirm that there is no residue on the surface through visual inspection and solvent wiping.7. Environmental protection and safetyDust removal system: The sandblasting room should be equipped with an efficient dust removal system to capture abrasives and dust and reduce environmental pollution.Personal protection: Operators should wear protective glasses, masks and hearing protection devices to ensure personal safety.Through the above steps, the sandblasting room can effectively create a flawless protective barrier for the workpiece surface, providing a good foundation for subsequent painting or other surface treatments.
