What are the functions of silicon carbide as a sandblasting material?
Silicon carbide includes black silicon carbide and green silicon carbide.
Silicon carbide is a kind of important blasting material,mainly embodies as follows:
1.Removing surface dirt and coating
Silicon carbide has a high hardness and can quickly remove dirt, oxide layer or old coating on the surface of the workpiece during sandblasting. Its excellent cutting ability can achieve the ideal cleaning effect without damaging the workpiece substrate.
2.Improving surface quality
The particle size distribution of silicon carbide sandblasting is concentrated and uniform, the impact force of particles during sandblasting is more consistent, and the cutting efficiency is higher. Silicon carbide particles with uniform particle size can ensure that the surface after sandblasting is smoother, reducing the difficulty and cost of subsequent processing. In addition, the surface after sandblasting is delicate and smooth, which can meet high surface quality requirements, such as surface treatment of automotive parts, aerospace devices, etc.
3.Enhancing coating adhesion
Sandblasting can make the cleaned surface obtain the required cleanliness and a certain degree of roughness at the same time, thereby improving the adhesion of the coating on the basic surface. Silicon carbide sandblasting performs well in this regard, ensuring a strong bond between the coating and the workpiece surface, and improving the service life and performance of the coating.
4.Excellent high temperature resistance
Silicon carbide has good thermal stability and can withstand sandblasting operations in high temperature environments. This gives it a significant advantage in handling high-temperature workpieces or situations where high-temperature sandblasting is required, ensuring the sandblasting effect while protecting the operator’s safety.
5.Wide range of application scenarios
Silicon carbide sandblasting is suitable for a variety of scenarios, including surface matte treatment of steel, steel pipes, steel structures and stainless steel products, cleaning of various molds, removal of tensile stress of various parts to increase fatigue life, cleaning and removing burrs before tinning of semiconductor devices and plastic-sealed tubes, shot peening and finishing of medical equipment, textile machinery and various hardware products, as well as cleaning and removal of burrs and residues of various metal pipes and non-ferrous metal precision castings.
