Terrazzo stone tiles are products made by mixing gravel, glass, quartz stone and other aggregates into cement binders or epoxy binders to make concrete products, which are then ground and polished on the surface. How to identify the four basic identification methods of terrazzo stone tiles? Let's take a look at it together.
1. Quantity, that is, measure the size and specifications of the stone, so as not to affect the splicing, or cause the pattern, pattern, and line deformation after splicing, and affect the decorative effect.
2. Test, that is, use a simple test method to check the quality of the stone. Usually drop a small drop of ink on the back of the stone. If the ink quickly disperses and leaches, it means that the internal particles of the stone are loose or there are microscopic cracks, and the quality of the stone is not good. On the contrary, if the ink drops stay in place, it means The stone is dense and has good texture.
3. View, that is, to observe the surface structure of the stone with the naked eye. Generally speaking, stone with uniform fine material structure has a fine texture, which is a good product of stone; stone with coarse grain and unequal grain structure has poor appearance effect, uneven mechanical properties, and slightly poorer quality. In addition, the stone often produces some fine veins and micro-cracks in it due to the influence of geological action. The stone is easy to crack along these parts and should be removed. As for the lack of edges and corners, it affects the appearance, so you should pay special attention to it when choosing.
4. Listen, that is, listen to the percussion sound of the stone. Generally speaking, a stone with good quality, dense and uniform inside and no micro-cracks will have a crisp and pleasant knocking sound; on the contrary, if there are micro-cracks or fine veins in the stone or the contact between the particles becomes loose due to weathering, the knock The sound of hitting is rough.
