How to choose stone materials for villa decoration?
, that is, observe the surface structure of stone materials with the naked eye. Generally speaking, the stone selection in Chinese decoration, the stone with uniform fine material structure has fine texture, which is the best stone; The appearance effect of coarse-grained and unequal grained stones is poor, the mechanical properties are uneven, and the quality is slightly poor. In addition, due to the influence of geological process, natural stone often produces some veinlets and microcracks, and the stone is easy to crack along these parts, so it should be removed. As for the lack of edges and corners, it will affect the beauty, so we should pay particular attention to it when choosing. Second, in the Chinese decoration of villas, pay attention to the size and specification of stones when using stones, so as not to affect the splicing, or cause the deformation of patterns, patterns and lines after splicing, which will affect the decorative effect. Listen for three times, that is, listen to the knocking sound of stones. Generally speaking, stones with good quality, dense and uniform interior and no micro cracks have a clear and pleasant knocking sound; On the contrary, if there are micro cracks or veinlets in the stone or the contact between particles becomes loose due to weathering, the knocking sound is rough and dumb. The fourth test is to use a simple test method to check the quality of stone. Usually drop a small drop of ink on the back of the stone. If the ink is dispersed and leached around quickly, it means that the particles in the stone are loose or there are micro cracks, and the stone quality is poor; On the contrary, if the ink drops in the original place, it means that the stone is dense and of good quality
