Study on the Dependence of Glossiness on the Micro-Uneven of Natural Granite Surface

Abstract:

In this paper, three kinds of granite were lapped and polished by loose abrasives. Glossiness and surface roughness of the lapped and polished granites were measured and the surface morphologies were observed. The experimental results revealed that the readings of roughness were very discrete. High glossiness can be achieved only when the surface roughness is decreased to a certain level. The average surface roughness of the three kinds of granite after being finely polished can reach 0.02～0.04um. Further reducing of roughness has little effect on the glossiness because the existence of the defects, which prohibits the further increase of the glossiness.
