Evaluation Method Of Granite

Finished finish finishing stone, its quality can be identified from the following four aspects:

One view, that is to observe the surface structure of stone. Generally homogeneous fine material structure of stone with exquisite texture, for the jiapin stone, coarse-grained and unequal-grained structure of the stone its appearance effect is poor, mechanical properties are uneven, the quality is slightly worse. In addition, due to geological effects of natural stone, often in which some fine veins and micro-fissures, stone most easily along these sites rupture, should pay attention to remove. As for the lack of angular angle is the impact of aesthetics, especially when choosing. Two volumes, that is, the size of the stone specifications. In order to avoid the effect of splicing or splicing after the pattern, pattern, line deformation, affect the decorative effect.

Listen to the percussion sound of the stone. Generally good quality, internal dense uniform and no micro-cracks of the stone, its percussion sound crisp and pleasing; conversely, if there is microscopic fissure or fine veins inside the stone, or because of weathering, the contact between the particles becomes loose, then the percussion sound is gruff.

Four-Test, that is, using simple test methods to test the quality of stone. Usually in the back of the stone on a small drop of ink, such as ink quickly scattered around the leaching, that is, the stone inside the particles are loose or there is a micro-fissure, stone quality is not good;

In the selection of finished plates, because the stone material is natural, it is impossible to have the same texture, in the mining process of the level of the difference. Most stone materials are graded. Granite stone No color stripes, most only color spots, there are some solid color. The finer the mineral particles the better.
