For the finished finished marble stone, the quality can be identified from the following four aspects:
One view, that is, the surface structure of the stone is observed by the naked eye. In general, the uniform fine material structure of the stone has a delicate texture, which is a good stone; the coarse grain and the unequal grain structure of the stone have a poor appearance. In addition, due to the influence of geological effects, the stone often produces some fine cracks in it. 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 important to affect the appearance, especially when choosing.
The second quantity, that is, the size specification of the stone, so as not to affect the splicing, or cause the pattern, pattern and line deformation after splicing, affecting the decorative effect.
Three listen, that is, listen to the sound of the stone. In general, the sound of a good quality stone is crisp and pleasing; on the contrary, if there is a slight crack inside the stone or the contact between the particles becomes loose due to weathering, the knocking sound is rough.
Four tests, that is, using a simple test method to check the quality of the stone. Usually a small amount of ink is dropped on the back side of the stone. If the ink is quickly dispersed and leached everywhere, it means that the inside of the stone is loose or there is a gap, and the quality of the stone is not good. Conversely, if the ink is not moved in place, the stone material is good.
1. Stone has a radioactive certificate, please ask the dealer when you purchase. Do not buy without a certificate, and at the same time, be aware that the home improvement should be a Class A product.
2. In the choice of marble and granite, marble should be considered first. Under normal circumstances, the radioactivity of granite is greater than that of marble.
3. Under normal circumstances, the consideration of stone should be black, grayish white, flesh red, green, red. From the radioactivity, from high to low, in order: red > green > flesh red > gray white > white > black, basically this Sorting.
