Marble, as a kind of commonly used adornment material, due to factors such as mineral composition or processing technology, the influence of the surface will present a different luster. In order to meet the requirements of different usage scenarios on the marble gloss, you need for the accurate determination of the gloss of marble. This paper introduces the gloss of marble requirements and measuring method, interested friends can look at!
Marble plate surface gloss of high and low white marble slabs will greatly affect adornment effect. Generally high quality marble plate polished surface should have mirror luster, as can be clearly reflected.
Due to different hardness, structure, mineral content, mineral particle size, the influence of stone glossiness is different, generally we will stone glossiness is divided into three levels of "good (gloss or gu, 80)," general "(gloss between gu, 70-80)," bad "(gloss under 70 gu)
Want to notice at the same time the requirements of white marble mosaic the different surface effect on the gloss is not the same. Commonly used polishing processing granite, marble, marble polishing glossiness but in about 80 gu, glossiness and granite can reach more than 90 gu, should maintain its gloss for a long time also need professional maintenance, marble surface glossiness after crystallization maintenance generally between 85 gu gu - 100 is a normal state. Dumb smooth surface is low gloss in 10 to 40 gu polishing, produce diffuse reflection, lacklustre, do not produce mirror effect, and won't produce light pollution. Smooth and dumb can difference is like a mirror reflecting the figure below, smooth surface is on the dummy based on precise polishing burnish.
In the usual decorative stone, gloss over pietra gray marble 75 gu can satisfy the requirement of general decoration, and some more advanced place need gloss and according to the requirements of testing.
The gloss of marble is refers to the ability of specular grey marble slab reflection of marble surface light, reflective ability is stronger, the higher the gloss, reflection ability weaker, the lower the gloss. Typically, evaluation method of stainless steel tube surface glossiness have visual method and instrument measuring method in two ways.
Visual observation, it is in a stable light source environment, the human eye directly through specific Angle to observe the surface gloss of plastics, this approach can accurately contrast samples and prototype luster difference, but for specific gloss level do not have method to assess, and the result of the determination of susceptible to the influence of light source, the viewing Angle, the viewer condition.
