During the production of highway painting, put glass bead into paint based on the ratio of 18-25% (weight percentage), so that the highway paint can still keep reflectivity during wear and friction. The ratio is refer to the specification of Communication Industry Standard of the People's Republic of China No. JT/T280-2004, the standards which is different in different countries and areas.
According to the specification of Communication Industry Standard of the People's Republic of China No.GB/T24722-2009, the granulometry is shown in the table below:
Ratio:2.4-2.6g/cm3 |
Reflectivity:≥1.50 |
Roundness:≥80% |
Contained ratio of magnetic particlea:≤0.1% |
The appearance of glass bead should be colorless, loosen and spherical particle, should be clean without impurity, and without agglomeration that can't be loosen by slight impact.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
PRODUCT DESCRIPTION
Glass Beads will clean metal parts without etching the surface. Glass Beads are commonly used for automotive restoration, polishing of castings, stainless steel fabrication, and light deburring of precision parts. Glass Beads are most commonly used in abrasive blast cabinets. Its round shape gently cleans metal parts, leaving a smooth, polished or matte finish.
ADVANTAGES
LOW DUSTING
Glass Beads are typically blasted at 60–90 PSI to achieve the most productive results. This lower PSI, along with glass bead's durability, produces lower dust levels than most mineral or slag abrasives. Low dust levels improve the operator's visibility of the work surface, increasing production rates. Lower dust levels also reduce cleanup costs on the work site.
RECYCLABILITY
Glass Beads are an environmentally-friendly and clean abrasive that is aggressive enough to clean and deburr parts, yet will not damage them. Glass beads can be recycled up to eight times or more. Abrasive blast cabinets provide the best recyclability rate.
APPLICATION FLEXIBILITY
Glass Beads can easily perform a wide variety of abrasive blasting jobs. Larger sizes can be used for the cleaning of automotive parts, castings, and deburring rough edges from castings and gears. Medium sizes are suited for blending surface defects and working with aluminum and stainless steel parts, providing a satin to matte finish. Fine sizes work best for light duty work and allow for fine detail work.
