Ceramic Blasting Abrasive Low Dust Production Low Equipment Wear

Ceramic beads also called ceramic media, ceramic bead blasting media, or ceramic blasting beads.It is of high hardness, good elasticity, high gloss and high impact strength. Ceramic blasting beadsmainly used for blast cleaning, debluring, removing oxice layers of castings and forging parts, alsofor metal surface finishing, and pretreatment before coating and plating.

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.

1. The size distribution of ceramic sand is uniform, and it has no porosity , high toughness, hardness, and impact resistance. High particle density can achieve the sandblasting strength of glass beads at a faster grinding speed. The elastic modulus of ceramic projectile is 330GPa, much higher than that of glass bead 60GPa, and the impact energy is large. To achieve the same shot peening effect in use can reduce the shot peening pressure, high shot peening efficiency, reduce energy consumption, thus reducing production costs.

2. Good stability, corrosion resistance to all kinds of chemical liquids, high temperature resistance, small coefficient of thermal expansion, high insulation.

3. The density of ceramic sand is between glass sand and steel sand, and the hardness is larger. In the sandblasting strength range, the ceramic sand can properly make up for the upper and lower limit blind area of the hitting strength of glass sand and steel shot iron sand. Comparing the effect of steel sand blasting, there is no iron element pollution to the workpiece, no metal powder residue on the workpiece surface, no color bias phenomenon to reduce the metal natural color, which can be used for the use of steel pellets and steel chip pollution.

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.
