sand blasting glass beads

  • Description
  • Inquiry

Glass beads  is widely used on metal surface cleaning or abrasive enhanced treatment process, mainly for sandblasting work. Glass beads are from high-quality crushed culled sorting made. Manufacturing, broken glass to melt into a ball and then annealed to eliminate the stress and prevent breakage. This transparent, clear product when using a spherical structure having a particle is not embedded in the work-piece, the work-piece, or have other pollution damage. Abrasives of different sizes and different operating parameters, the type of glass beads reach the surface gloss. The choice of glass beads in the work-piece surface selectively controlling local coverage blast may have a particularly decorative effect.

 Chemical Composition:

1.chemical composition:SiO2 >67%,CaO>8.0% MgO>2.5% Na2O<14%, Al2O3 0.5-2.0 Fe2O3 >0.15其他2.0%

2.ProPortion:2.4-2.6g/CM3

3.Bulk density:1.5g/cm3

4.Mohs hardness:6-7mohs

5.Rockwell hardness:48-52 HRC

Features: 
1, the chemical composition of inert silica chemical activity without interference concerns; 
2, the circular elastic particles, impact resistance, can be recycled many times, less wear and tear; 
3, spray a small abrasion and prolong the service life of the nozzle; 
4, the surface of a sphere, will not damage the machined surface and precision size; 
5, after treatment, the surface is smooth, with a special beauty, improve product value; 
6, suitable for dry, wet blasting operations; 
7, the metal fine cracks with a fine glass beads in the wet blasting easily displayed; 
8, after the workpiece has a matte effect, highlighting the qualities of metal, rust, etc., without the need for pickling rust treatment 
 
Uses: 
1, the beads hit aviation parts, eliminate stress, to increase the fatigue strength and reduce friction and wear; 
2, sand-blasting, paint, in addition to carbon, with the exception of machining marks; 
3, before anodizing and plating, in addition to cleaning outside can help increase adhesion; 
4, weld steel workpiece cleaning and removal of surface scratches and other beauty processing; 
5, line cutting clean rust mold; 
6, in addition to dirt rubber molds; 
7, with reflective road marking; 
8, the appearance of decorative art;
