Detailed Product Description

 

Name: Hetian zirconia beads

Category: yttria zirconia beads
Technology: Sintering
Size :0.2-60mm
Density: 6.0g/cm3
Accumulation of proportion: 3.6g/ml -3.7g/ml
Hardness: 1250HV1
 
  Intensity of high hardness, excellent wear resistance, in particular, applicable to all types of high shear energy sanding machine, sanding machine in the conventional bedroom also has a better application.

The use of yttria as stabilizing agent, with a special forming process, high temperature burn-baking phase of the process are made. Zirconia grain size ≤ 0.5um to ensure that the beads of fine, dense microstructure. With low wear, high fracture toughness and good corrosion resistance. At the same time, pearl-like luster and smooth spherical work deserves the best in the grinding media.
       This product is particularly suitable for vertical stirred mill, horizontal rolling mill, vibration mill, and various high-wire-speed sanding stick pins, etc.; the requirements of the refusal to cross-contamination of the slurry and powder for wet, dry dispersion and the ultra-fine grinding.

Features:
1, wearing a very low (ppm) the amount of materials to prevent pollution
2, High grinding efficiency
3, Extremely long life, low cost integrated
4, for high viscosity, wet grinding and dispersion of occasions

Applications:
1, wear-resistant, corrosion-resistant products: paints, textiles, paints, printing and dyeing
2, high strength, high toughness products: magnetic materials, piezoelectric ceramics, dielectric ceramics
3, to prevent pollution: medicine, food, cosmetics
4, Ceramics: Electronic ceramics, refractory ceramics, structural ceramics
