The quality of finished finished marble stone tile can be identified from the following four aspects:
One view, that is, the surface structure of the natural marble tile is observed by the naked eye. Generally speaking,the white grey marble with uniform fine structure has fine texture and is the best for stone; the coarse grain granite decoration and the stone with unequal grain structure have poor appearance effect, uneven mechanical properties and poor quality. In addition, due to the influence of geological effects in natural stone, some fine veins and micro-cracks are often produced in it, and the stone is most likely to rupture along these parts, and should be removed. As for the lack of edges and corners, it is more affecting the appearance, especially when choosing. Two quantities, that is, the size specifications of the stone. In order to avoid affecting the splicing or causing the pattern, pattern and line deformation after splicing, affecting the decorative effect.
Listen three times, that is, listen to the sound of the white grey marble. Generally speaking, the natural marble tile with good quality, uniform internal density and no micro-cracking is crisp and pleasant; if there is micro-crack or fine vein inside the marble stone tile, or the contact between the particles becomes loose due to weathering, tapping The voice is hoarse.
Four tests, that is, using a simple test method to check the quality of the guangxi white marble. Usually a small drop of ink is dropped on the back side of the stone. If the ink is quickly dispersed and leached everywhere, it means that the inner particles of the stone are loose or there are micro-cracks, and the quality of the stone is not good; otherwise, the china white marble is dense and the texture is good.
In the selection of finished plates,since the white grey marble raw materials are natural, it is impossible to have the same texture, and the level of the process in the natural marble tile process is also different. Most marble stone tile grades are graded. Granite stone has no colored stripes, most of which have only colored spots, and some are solid colors. The finer the mineral particles, the better.
