The process of cleaning and roughening the surface of the substrate by using the impact of high-speed sand flow. Compressed air is used as power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, emery, iron sand, Hainan sand) at high speed onto the surface of the workpiece that needs to be processed, so that the appearance or shape of the outer surface of the workpiece surface changes. , due to the impact and cutting effect of abrasives on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, which improves the mechanical properties of the surface of the workpiece, thus improving the fatigue resistance of the workpiece and increasing its interaction with the coating. The adhesion between layers extends the durability of the paint film and also facilitates paint leveling and decoration.

Sandblasting (referring to metal surface rust removal or plating on metal surfaces) uses quartz sand, ordinary quartz sand, refined quartz sand: high hardness, good rust removal effect,

Quartz sand It is quartz particles produced by crushing and processing of quartz stone. Quartz stone is a non-metallic mineral. It is a hard, wear-resistant and chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white, or colorless and translucent, with Mohs hardness. Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries.

Ordinary quartz sand is generally made of natural quartz ore, which is crushed, washed, dried and screened twice. SiO2≥90-99%Fe2O3≤0.06-0.02%, refractoriness 1750℃, appearance : Some large particles have yellow skin cysts on the surface.

Lingshou Yapeng-Refined quartz sand is an important industrial mineral raw material, widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. Common specifications: 0.1-0.5mm, 0.5-1.0mm, 0.6-1.2mm, 1-2mm, 2-4mm, 4-8mm, 8-16mm, 16-32mm (mm is millimeter unit); 2-4 mesh, 4 -6 mesh, 6-10 mesh, 10-20 mesh, 20-40 mesh, 40-70 mesh, 70-120 mesh, 120-200 mesh, 200 mesh, 325 mesh, 600 mesh, 1250 mesh, 2500 mesh.
