What sand is used for sand blasting and rust removal?
As for pomegranate sand, because it is a non-metallic mineral, there is no free silicon and harmful heavy metals, which can avoid respiratory diseases such as silicosis and cancer. In addition, due to its large specific gravity and fast natural sedimentation rate, dust and dust are very few after six times of water washing in the production process, which can avoid pneumoconiosis and meet the environmental protection and health requirements of sand blasting. Therefore, pomegranate sand has been used to replace traditional abrasive in the world for many years.
Why pomegranate sand will remove rust is because the hardness of RZG garnet itself is 7.5-8. After four times of crushing, the edges and corners are very sharp, and they are rhombic 12 polyhedron or quadrilateral 38-sided crystal with very strong grinding force. It is sprayed on the surface of the workpiece to be treated at high speed under the action of compressed air. Due to the impact and cutting effect of pomegranate sand on the workpiece surface, the rust layer, oxide and oil stain on the workpiece surface can be quickly removed. Make the surface of the workpiece obtain certain cleanliness and different roughness, improve the mechanical properties of the surface of the workpiece, improve the fatigue resistance of the workpiece, increase its adhesion to the coating and prolong the durability of the coating.
