| Message: | Glass beads is a new type special material of wide uses and low cost,the appearance of smooth, round, glass transparent and free of impurities.
Sand blasting
ZW Glass beads abrasive is widely used to clean metal surface hardening treatment or other processes, mainly for sandblasting equipment. Manufacture of broken glass to melt into a ball and then annealing to eliminate internal stress and prevent breakage. The transparent and clear spherical structure will not have particles embedded in the workpiece during using. Using different sizes and different operating parameters abrasives, glass bead peening can achieve different gloss on the surface.
Road Marking
ZW Glass Beads for Road Marking can improve visibility of the traffic markings and road signs and supply safer night driving conditions.
Grinding & Dispersion Media
Pigment, ink, calcium carbonate, magnetic material, painting industry, color mixing in so-called bead mills,functional particle such as fluorescent substance.
Reflective Material
High refractive index glass beads are necessary materials for reflective fabric, reflective coatings, chemical coatings, advertising materials, clothing materials, reflective film, reflective fabric, reflective signs marking, airport runways, hats, bags, land and air rescue supplies, personnel wearing at night-time activities.
