Stone Material Purchase Standard
Stone to view: the naked eye observation of the surface structure of stone. In general, the fine texture of the fine material has a delicate texture, which is the best material for the stone. The stone material of the coarse grain and the unequal grain structure is of poor appearance, and the mechanical properties are not uniform, and the quality is slightly worse. In addition, natural stone due to the impact of geological processes often in which some of the thin veins, micro cracks, stone most prone to rupture along these sites, should pay attention to remove. As for the lack of edge angle is more beautiful, you should pay attention to the choice.
Two quantities: namely the size of the volume of stone, so as not to influence splicing, or caused by splicing patterns, patterns, lines, deformation, affecting the decorative effect.
: listen to listen to three stone percussion sound. Generally speaking, the quality is good, the internal compact and uniform and no micro cracks of stone, the percussion sound crisp and sweet; on the contrary, if there is no stone internal micro cracks or fine veins or due to weathering caused by contact between the particles loose, then knock on the sound.
: four test is a simple test method to test the quality of stone. Usually in the back of the stone on a small drop of ink droplets, such as the ink quickly spread around the leaching, it means that loose particles inside the stone or the existence of microscopic cracks, stone quality is bad; on the contrary, if the ink drops in the same place without moving, dense texture of the stone.
