Glass Beads

Glass Bead/Glass Sphere is a glass type round abrasives for sand blasting and shot blasting made of glass sand. It's a transparent, but appears white. Our glass bead is pure and with low silica content. Standard for Glass Beads are EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.

Glass Beads has certain level of hardness,strength and elascity, can be reused and not easy to break. Our Glass Beads has fine particle distribution and high roundness rate which make sure that surfaces of working pieces are evenly cut or polished. Also high chemical stability and clean surfaces do no harm to metal surfaces.

Glass Bead (Glass Bead) is a unique abrasive material that widely used in cleaning or metal surface strengthening treatment. It is mainly used for sand blasting equipment. Glass beads are made from the high quality glass crushed sorting. In the process of producing, the broken glass was firstly fused to spherality and then annealing again in order to eliminate internal stress and prevent damage. The transparent and clear sphere products won't have any particles that embedded in the use of the workpiece and pollute artifacts or other damages. Using the grinding of different size and different operation parameters, glass beads will achieve different effect of gloss in the surface of workpiece. And choosing the glass beads which can control sand blasting selectively. It will make special decorative effects.

The good performance of glass beads will not damage the surface of workpiece that have strict request for deviation of workpiece to clean or deburring. Glass beads are very suitable for use. What’s more, the strength of the glass bead inherent can be used for the circulation of abrasive equipment.
Glass beads are widely used in the process of workpiece surface with residual tension or periodic pressure. It will produce compressive stress layer and achieve the purpose of surface strengthening. Using glass bead reinforced surface which can reduce surface erosion or surface fatigue and other potential hazards.
The use of glass beads is very cost-effective and precise control for surface treatment.
Chemical properties of glass bead is abortion non-toxic. It will not remain iron substances or other pests in the surface of workpiece and also not bring negative influence to the environment during use.

Classification:
1. Accessories with glass beads
2. Glass bead for used in road
3. Mechanical sand blasting, polishing glass beads
Mechanical sand blasting, polishing glass bead is clean, transparent and no bubble and impurities. Its round rate is greater than 90%, mainly used in metal cleaning and polishing. It make objects restore clean degree while keeping the accuracy. It is used for mechanical sandblasting and increase the surface hardness.

The range of industrial application:
Aviation industry; the automotive industry; sandblasting/painting business; Manufacturing of Consumer products; the casting industry; the subcontractor; the semiconductor industry.

The range of process application:
The cleaning of integrated circuit blocks support; Strengthen the aircraft engine turbine blade and other parts; Decoration; electroplate or electrolytic coating surface treatment before plating; the clean of iron components or deburring; clean up the waste residue of molten material in high temperature mold.

Applications:
1. Sand blasting glass beads:
Glass beads can press forging, pressure, glass, rubber, plastic, metal casting, extrusion and other tools cleaning.
Glass beads can eliminate tensile stress, increase fatigue lifetime and improve the ability of resistance to corrosion. Such as aircraft engine turbine, blades, gear shaft, gear, all kinds of springs, hydraulic parts, etc.
Glass beads can be applied to the circuit board, encapsulation of tin on the tube before cleaning and removing waste edge burr.
Glass beads can remove the piston and cylinder blockages. Provide light and matt surface for medical machine tools and auto parts.
Glass beads can be applied to the cleaning of motor, overhaul of the coil, brush rotor parts, etc.
Glass beads can be applied to all kinds of metal, non-ferrous metal precision casting cleaning and deburring, the shot peening and optical processing of textile machinery parts and components.

2. Glass beads used in road:
Glass beads can be mainly applied to normal temperature and hot melt traffic coatings. It can be divide into premixed and surface glass beads, and premixed type glass beads can be mixed in the coating during the production of hot melt road coating. It can ensure long-term reflective of in the life period of road marking. Another type can be spreaded on the surface of road marking during road construction so that achieve instant reflection effect.
After surface treatment of coated glass beads, it can greatly increase the adhesion force of glass beads and hot melt marking, enhance the refractive index of road marking. What’s more, this kind of glass bead possess the ability of self-cleaning, dirt and moisture resistance, etc. This kind of glass beads applied to coating resistance to improve pavement performance and the security of the driver at night.

3. Glass bead applied to industrial shot peening and additive:
Glass beads can be used in the metal surface and the mould surface, neither damage to the workpiece surface, and improve the precision of the workpiece. It can be used for cleaning and polishing of metal, plastic, metal jewelry, precision casting and so on. This kind of glass bead is widely used in the high-grade finishing materials at home and abroad.

4. The glass beads are still widely used in the field of medical equipment, nylon, rubber, engineering plastics, aviation and so on as a new kind of material. Such as additive, enhancer, etc.

5. The high refractive index glass beads is the necessary material for reflective fabric, reflective coatings, chemical coatings, advertising materials, clothing materials, reflective film, reflective fabric, reflective sign identification, airport runway, shoes and hats, bags, the sea life preserver, nocturnal staff wearing required materials and other products.

Use guide:
The large size glass beads cleaning up slowly, producing strong efforts in strengthening, removing pollutants and then producing high quality surface finish.
The small size glass beads cleaning up fast, producing strong efforts in strengthening, cleaning up smaller pollutants and then producing poor quality surface finish.
