Ceramic beads B20 Zircon sand for Aluminum finishing

Ceramic beads B20 Zircon sand for Aluminum finishing

The main component of ceramic shot is zirconia, which is mainly used for surface treatment such as sand blasting and shot peening. The production process of ceramic shot is to melt high-quality imported zircon sand into liquid at high temperature, and then spray it into balls. The zirconia ceramic spheres are sieved and removed by magnetic separation to obtain particles with high roundness, high strength and uniform particle size. The spherical particles of ceramic shot can achieve better surface brightness during sandblasting, while the workpiece itself does not change color. It is widely used for sandblasting and surface treatment of aviation parts, stainless steel plates, structural parts, stainless steel kitchenware, medical devices, mobile phone / laptop shell, automobile chassis / engine, sports equipment and other industries.

Characteristics of Ceramic beads B20 Zircon sand for Aluminum finishing :

1. High strength and wear resistance. The main component of ceramic shot is zirconia, which is characterized by small crystal size and high wear resistance.

2. Ceramic shot has high hardness, with Vickers hardness (microhardness) of 700HV and Rockwell hardness of 600HRC The density and specific gravity are also much higher than those of glass beads.

3. No dust, high abrasion resistance and strength make it difficult for ceramic shot to be broken during sand blasting, so it is not easy to generate dust.

4. Sandblasting effect: the surface finish is high. Using ceramic shot sandblasting can achieve smooth satin surface brightness. Using ceramic shot of the same specification is 60-70% lower than that of glass bead sandblasting.

5. It is applicable to various metals and nonmetals, such as titanium alloy, magnesium alloy, aluminum alloy, stainless steel, carbon steel, brass and alloy, acrylic, plastic and other materials. Ceramic shot will not react or oxidize with metal, and there is no metal residue, so it will not affect the color of the workpiece.

6. It is suitable for dry blasting and wet blasting. The surface of ceramic shot is very smooth, and the wear of sand blasting equipment is very small.

7. Ceramic shot has high sandblasting efficiency and long service life, and its recycling times can reach 25 times of glass beads.

8. The roundness is high, and the proportion of abnormal balls and snowman balls adhered between the spheres is low.
