Zirconium silicate microsphere B120 B170 B205 Blasting media

 

The significant advantage of zirconia beads for shot blasting is their high durability and the ability to be cycled dozens of times. Zirconia bead ceramic sand has low magnetic content and high spheroidization rate, making it suitable for forming a matte and glossy sandblasting surface.

 

Characteristics of Zirconium silicate microsphere B120 B170 B205 Blasting media:

1. It has a significant weight, high wear resistance coefficient, high mechanical strength, and a Mohs hardness of 7.0, suitable for most metal alloy materials.

2. Spherical particles will not scratch the metal surface, and can also eliminate stress and improve the surface brightness of the sandblasted material.

3. The crystal size of zirconia is small, and its high strength and dense organizational structure can prevent particle breakage and prevent the generation of dust.

4. The main chemical components of ceramic sand are zirconia, silica, and alumina, with low magnetic content and iron content below 0.1%, which will not produce metal iron residues.

5. The number of cycles and shot peening smoothness are tens of times better than glass beads.

Application of Zirconium silicate microsphere B120 B170 B205 Blasting media:

1. The mechanical industry, such as precision molds, gears, and bearings, undergoes shot peening and brightening treatment. It can also clean the burrs and burrs of molds and mechanical parts.

2. Medical equipment in the industry, such as surgical knives, artificial joints, and human implanted alloy materials, are sandblasted and polished to achieve a bright and non reflective surface effect.

3. Surface shot peening treatment for high-speed rail and automotive parts. It can be used for sandblasting the surface of high-speed iron aluminum alloy components, car engine casings, car wheels, new energy vehicle accessories, and other parts to enhance the metal texture and form a smooth satin effect, preparing for subsequent surface painting. At the same time, shot peening with zirconia silicate beads can also improve fatigue strength and enhance the impact resistance of alloy components.

4. Electronic products such as mobile phones, tablets, and smartwatches have sandblasted metal casings. After shot peening, the metal shell has a uniform and soft matte brightening effect, while also possessing anti fingerprint touch characteristics.

5. In the field of daily use, such as alloy parts of kitchenware and sports equipment, after sandblasting with zirconia silicate beads, the surface metal effect is delicate, antibacterial, and prevents fingerprint residue. It can replace chemical methods for brightening treatment, prevent chemical pollution, and improve surface treatment efficiency.

6. The fatigue resistance and surface stress elimination of aerospace components such as aircraft wings, turbine blades, gears, landing gears, and other aerospace mechanical components.
