People often use the surface gloss and smoothness of the panel smooth stone two concepts. These two indicators can be measured. For flat plate, flatness can be done for the surface processing of a kind of quality standard, but if it is a processing standard for polishing stone, it is only one aspect. Gloss can be seen as a measure of the apparent characteristics of the stone panel, but there is no saying that there is a standard for the evaluation of the quality of surface processing. Different varieties of stone, the processing of the gloss is not the same, this time can not be considered that the relatively low gloss of stone, the surface quality is low. For the same variety of stone, gloss can be used as a stone panel surface processing quality evaluation criteria. And the same variety of the same origin of the same processing plant in the same variety of stone light panels are almost the same gloss of finished products, then gloss as the evaluation criteria for the quality of surface processing has lost significance. This shows that there is no standard for the evaluation of the quality of the surface of the light panel stone. The processor is mainly based on their experience and production experience, consumers mainly according to their own understanding.
This paper presents a simple method for evaluating the surface quality of a light panel stone, and discusses it. That is, in the 5 ~ 10 times the magnifying glass observation, if you can not see the hair surface, cracks, scratches, holes and depressions, the quality of the stone surface processing can be considered very high. This standard applies only to the polishing of the light panel stone, and the crack hole mainly refers to the formation of improper processing.
