1. Core performance parameters and material advantages
Definition of 95 zirconia beads : 95 "refers to ZrO ₂ content ≥ 95% (with the rest being Y ₂ O stabilizer), sintered at 1650 ℃ to form t-ZrO ₂, including:
High hardness: can spray metal hardness below 8.5-9, wet hardness of 1500-1600HV, HRC 60;
Low wear rate: The self wear during sandblasting operation is less than 0.01%/100h, which is 1/50 of traditional glass beads (wear rate of 0.5%/100h);
Internal corrosion: Soak in a 30% hydrochloric acid and 40% sodium hydroxide solution for 1000 hours, zero gravity<0.05%, suitable for preventive spraying in the chemical industry.
structural advantage
Density ≥ 99.5%, crystal humidity<1, using static forming process, etc. During sandblasting, the impact energy is evenly distributed and will not produce fine cracks on the material surface.

3. Application scene and craftsmanship of sandblasting beyond the industry
Metal Surface Treatment Area
Car Wheel High Strength Sandblasting:
Choosing an inlet beam of 0.8-1.2mm and spraying sand at 0.6-0.8MPa atmospheric pressure, it can quickly remove oxide skin from the surface of the wheelbase (aluminum alloy ADC6), and the roughness Ra is 12.5-25 μ Up to m can provide ideal anchoring surface for subsequent plating/spraying and beam wear is 80% less than steel sand.
Aviation Titanium Alloy Parts Paint Removal:
Using 0.3-0.5mm zirconium beads to spray sand at 0.4MPa low pressure, it can accurately polish the old coating of titanium alloy (Ti-6Al-4V) surface, and the photoconductivity of the gas surface (Ra ≤ 0.8) μ m) can satisfy the loss-free inspection requirements of aircraft maintenance (MRO) without damaging it.
Precision Ceramics and Electronics
Cell Phone Screen Glass Precision Sandblasting:
Surface roughness Ra is 0.5-1 by using 0.1-0.2mm ultraviolet in combination with automatic rotating plate equipment (rotation speed 500rpm) to realize glass (Corning® Gorilla® Glass) at 0.2MPa atmospheric pressure μ It is controlled by m, and the loss of transmittance is <1%, superior to the loss rate of 2-3% of aluminum oxide sand.
Semiconductor Wafer Corner Grinder:
Using 0.05-0.1mm nanoscale beads to spray sand at ultra-low pressure of 0.1MPa, the edge roughness of the silicone wafer (12 inches) is Ra<0.2 μ It can be lowered to m to avoid collapse defects and meet the harsh demands of SEMI standard intermediate crystalline edge treatment.
Food Medicine and Cosmetics Industry
Medicinal Glass Bottle Scrub Display:
Choosing food grade zirconium beads (FDA 21 CFR 174.5 compliant) and spraying sand at 0.3MPa atmospheric pressure can form a clear scrub font on the glass bottle surface, resulting in ZrO₂ particles due to bead wear <1 μ m, 0.22 μ m The impurity content of the solution <1ppm after roughing the filter membrane.
Cosmetic Compact Metal Case Settings:
Using 0.2-0.4mm beam spray to form a uniform gloss-free texture and control the surface reflectivity to 15-20%, while avoiding the Fe ion residue caused by traditional steel sand spray (ICP inspection <0.1ppm), it meets the safety requirements for contact materials of the EU Cosmetics Regulation (EC 1223/2009).
