The application of sandblasting room

The sandblasting room is a kind of machine that can spray various abrasives (silica sand, iron sand, steel shot, etc.) on the surface of the workpiece with air pressure. The abrasive sprayed on the surface of the workpiece is impacted on the metal surface to remove surface impurities, rust, paint, oxide scale, etc. According to the spraying method, it is divided into self-priming type and press-in type. Because the press-in type is to mix and spray compressed air and abrasive in the same container, the compressed air is fully utilized, and the air flow and sand volume are easy to adjust. It is suitable for large-area cleaning with high efficiency and is also widely used in pipes. Clean the inner wall.

What is sandblasting: a method of cleaning the surface with high-speed moving gravel. Can remove the surface oxide scale, grease, paint, etc., to obtain a more uniform surface quality. The subsequent process can be welding, oxidation, coating, surface chemical heat treatment, phosphating, etc. Sandblasting can generate residual compressive stress on the surface of the workpiece and make the surface quality of the workpiece uniform, which can improve the fatigue strength of the workpiece. The strengthening effect is worse than that of shot blasting, and the deformation of the workpiece is smaller than that of shot blasting.

Application range of sandblasting room:

  1. Pretreatment: Electroplating, painting, spraying, etc. are all covered by sandblasting before processing, the surface is cleaned, and the adhesion and corrosion resistance of the covering layer are greatly improved.
  2. Cleaning: Casting parts, stamping parts, welding parts, heat treatment parts and other metal workpieces to remove oxide scale, residue, dirt; surface cleaning of non-metallic products, removing black spots on the surface of ceramic blanks and reducing paint patterns, etc.
  3. Refurbishment of old parts: refurbishment and cleaning of all moving parts such as automobiles, motorcycles, and electromechanical equipment. At the same time, fatigue stress is eliminated and service life is prolonged.
  4. Light decoration: all metal products and non-metal products (plastic, crystal, glass, etc.) surface traces are eliminated, and the argon light matte surface treatment improves the quality of the product surface.
  5. Mold processing: argon matte surface treatment of the mold surface, graphic production, and mold cleaning, so as not to damage the mold surface and ensure the accuracy of the mold.
  6. Burr treatment: Removal of tiny burrs on machined parts, and burrs on injection molded parts.
  7. Rework of defective products: Removal of defective covering layer of products, removal of defective surface coloration and printing.
  8. Strengthening: Increase the surface hardness of metal parts and eliminate stress, such as surface treatment of aircraft blades, springs, machining tools and weapons.
  9. Etching anti-skid processing: metal products, non-metal products surface etching patterns, text and anti-skid treatment, such as: marble, anti-skid handles, seals, stone inscriptions, etc.
