Zirconia Electric Melting Shot Peening Media Pellet 0.8mm
DESCRIPTION
Zirconia itself is a metal oxide that can be made by reacting zirconium silicate or prepared from other compounds containing zirconium, the main component of which is zirconium. The raw material for zirconium is zircon sand, which is mainly produced in Australia, Indonesia, South Africa, Vietnam and the coastal areas of the South China Sea. Among them, Australia and Indonesia's zirconium sand is the best, not only the chemical composition meets the requirements, the production of zirconium silicate whiteness is also very good, of course, its price is relatively high.
ATTRIBUTE
The particle size of high-performance zirconia microbeads is between 0.8mm-2.2mm, with 94.6% zirconia content, white luster, Mohs hardness of more than 9 (HRA can reach more than 90), density of more than 6.0g/cm3. Due to high toughness and wear resistance, thermal expansion coefficient of 4-7×10-6/℃, compressive strength of 1000-1300MPa, with low wear (0.02kg/h).
APPLICATION
Zirconia Electric Melting Shot Peening Media Pellet 0.8mm can be used for blast pretreatment beforecoating or plating.
Among all surface cleaning methods, the ceramic beads sandblasting method is a thorough, universal, and extensive method, because:
1. Sandblasting is more efficient, thorough and cheaper than other pretreatment processes.
2. The sandblasting process allows you to freely choose the cleanliness and roughness of your workpiece.
ADVANTAGES
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.
