As a new type of surface treatment equipment, blasting equipment has been continuously developed, improved and perfected. It has a unique processing principle and a wide range of processing and application fields. It has been widely used in instruments and meters, machinery manufacturing, printing and dyeing machinery, electronic appliances, Medical equipment, crafts, textile machinery, ceramics, machinery repair and many other fields. Sand blasting equipment is becoming more and more popular in the modern surface treatment industry.
The main functions of the blasting equipment are fourfold:
1.Sandblasting equipment is used for pretreatment before coating of workpiece surface
Sand blasting equipment can be used as a pre-treatment process for various electroplating processes, brush plating processes, spraying processes and bonding processes to obtain active surfaces and improve the adhesion between plating, coatings and bonding parts.
2.Sandblasting equipment is used for finishing the workpiece surface
Sand blasting equipment can change the surface roughness Ra value of the workpiece, and produce a matt or diffusely reflected workpiece surface to achieve the purpose of finishing.
3.Sandblasting equipment for cleaning the surface of the workpiece
Sand blasting equipment can be used for the rust layer of metal, the residual salt and oxide layer on the surface of heat treated parts, the oxide layer on the surface of rolled parts, the oxide layer on the surface of forged parts, the oxide layer on the surface of welded parts, the molding sand and oxide layer on the surface of castings The residual dirt and tiny burrs on the surface of the machined parts are treated to remove the surface adhesion layer and expose the original color of the substrate.
4. Sand blasting equipment can change the physical and mechanical properties of the workpiece
Sand blasting equipment can change the surface stress state of the workpiece, improve the lubrication conditions of the mating parts, reduce the noise during the movement of the mating parts, harden the surface of the workpiece, and increase the wear resistance and fatigue resistance of the parts.
