Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece can be obtained with a certain degree of purity and various roughness, and the mechanical properties of the surface of the workpiece can be improved, which increases the fatigue strength of the workpiece, increases the adhesion between it and the coating, prolongs coating film service life, promote coating leveling and decoration, remove impurities, color variegation and oxide deposits on the surface, and at the same time roughen the surface of the medium, so as to eliminate the residual stress of the workpiece and improve the surface hardness of the substrate.

What types of sand materials are used for sandblasting machines?

Many products need to be sandblasted before they can be used, and different and same abrasives can be selected according to different process requirements. As a rule, 18–24 mesh is sufficient. Generally, the larger the mesh number, the finer the particle size. Which sand to use, you can refer to the following to choose.

Currently, there are several types of sand used in Zoji sandblasting machines on the market. Commonly used sands: brown corundum, white corundum, glass sand, quartz sand, zirconium corundum, black corundum, green silicon carbide, polymer sand. , ceramic sand, polymer sand, steel sand, steel shot, alumina sand, silicon carbide, etc.

What types of sand materials are used for sandblasting machines?

The key to the type of sand used is what is the purpose of sandblasting? What is a sandblasting product? What are the requirements for the sandblasting process? More brown corundum is said to be used. If the product material is stainless steel, and the purpose of sandblasting is to clean the surface, relatively speaking, more glass sand is used.

Among them, alumina sand is mainly used as an abrasive material because it is not easy to grind, which can improve the working conditions of workers. However, quartz sand is still used more in manufacturing, mainly due to its low cost and recyclability. When sandblasting, abrasives with different particle sizes and the pressure of compressed air used in sandblasting should be selected according to the workpiece material, surface condition and processing requirements.
