Three Key Points Of Stone Selection And Identification

1、 In addition to color selection, the function of the building should also be considered. In the home, the decoration of the living room and bedroom should use warm colors to show warm and comfortable mood; The decoration used for toilets and kitchens should be light, elegant and cool to show cleanliness.
2、 The intention of decoration and environmental impact Due to the different parts of natural facing stone decoration, the selected stone types are also different. When it is used for outdoor building decoration, it needs to withstand the wind, rain and sun during the water period. Granite has no carbonate, low water absorption and strong weathering resistance. It is better to select various types of granite stones; The facing stone used for the floor decoration of the hall requires stable physical and chemical properties and high mechanical strength, and granite stone should be preferred; For the decoration of the dado and the floor of the bedroom, the mechanical strength is slightly poor, and marble with beautiful patterns should be selected.
3、 To identify the quality of finished decorative stone, the quality of finished decorative stone can not be identified from the following four aspects;
(1) Observation. Namely, observe the surface structure of the stone with the naked eye. Generally speaking, the stone with uniform fine material structure has fine texture and is a good stone product; The appearance effect of stone with coarse grain and unequal grain structure is poor, the mechanical and mechanical properties are also uneven, and the maintenance quality of stone is slightly poor. In addition, due to the influence of geological process, natural stone often produces some fine veins and micro-cracks in it, and the stone is most likely to break along these parts, which should be removed. As for the lack of edges and corners, it is more important to pay attention when selecting.
(2) Quantity. That is, measure the size of the stone so as not to affect the splicing, or cause the pattern, pattern and line deformation after splicing, and affect the decoration effect.
⑶ Listen. That is, listen to the knocking sound of stone. Generally speaking, the stone with good quality, dense and uniform inside and without micro-cracks has 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 will be hoarse.
(4) Test. That is to use a simple test method to check the quality of stone. Generally, a small drop of ink is dropped on the back of the stone. If the ink is dispersed and leached quickly, it means that the internal particles of the stone are loose or there are micro-cracks, and the quality of the stone is poor; On the contrary, if the ink drops in place, it means that the stone is dense and has good texture.
