ZW Steel Grit has Moderate hardness, strong toughness, shock resistance, with the characteristics of repeated use.
And has long service life, good elasticity, strong adhesion, fast cleaning speed, low sand consumption, no breakage, cleaning workpiece brightness,effective on the surface of the workpiece, quickly clean the surface of the effect, processing of the workpiece surface quality is good, can be used for a long time.
The cleanliness of metal surface treated by ZW steel grit is up to international standard.
Steel grit 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 .
Surface preparation for painting and coating ,derusting of metal surface ,removal of old coatings from steel structural, cleaning of castings
and forgings,cleaning of welded areas, cleaning the squeezing roller,cleaning the scales, rust, burr, painting or plating before treatment,etching
Large grits used for sand removal of large and medium sized castings,scale removal of forging and heat treatment pieces,steel plate surface
blast cleaning,cutting granite,etc; Small grits used for sand removal of medium and small sized casting ,forging and heat treatment pieces,
aluminum ,steel pieces,steel plates ,steel structure and cleaning of non ferrous castings.
The larger the diameter of the steel shot is, the higher the surface roughness after cleaning is, but the cleaning efficiency is also high; the cleaning efficiency of irregularly shaped steel sand is higher than that of the spherical shot, but the surface roughness is also high.
