Bearing steel grit
ZW Bearing steel grit is made of high chromium bearing steel grit,it goes through material classify?heat treatment?crushing?different size screening?heat treatment production procedures.It can get good microstructure and optimum mechanical characteristics by special heat-treatment,which has features of high wear resistance,high fatigue resistance,low consumption,long lifetime,etc.Bearing steel grit working-life is longer 30% than traditional cast steel grits, the savings from this can be huge.

Steel grit
ZW Steel grits has been divided into three groups of different hardness according to their intended purpose.The hardest material GH, is designed for use exclusively in air blasting equipment. The two softer materials, GL and GP, may also be used in centrifugal wheel blast equipment.
Steel Grit Hardness Selection:
GP steel grit :
The GP steel grit external form is round and shape, even GP steel grits are softer than GL and GH,but owns fine elasticity and the strength of fatigue resistance as a result of fine heat treatment, so GP steel grit applied in all aspects .
GL steel grit :
The GL steel grit is harder than GP steel grit, but during blasting ,GL steel grit also loses its sharp edges, GL steel grit is particularly suited to descaling, operations before coating and surface preparation applications.
GH steel grit :
The GH steel grit has maximum hardness, it will not lost their angular during operating. These abrasives are particularly effective in surface treatment processes and produce a uniform surface, GH steel grit used for surface cleaning of high hardness products and surface roughening operations effectively .
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.
