the way to distinguish
First view: visual observation Stone Surface texture. Generally speaking, the stone with uniform fine material structure has a delicate texture, which is a good product of 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, some veinlets and microcracks are often produced in natural stone, and the stone is most likely to crack along these parts, which should be removed. As for the lack of edges and corners, it will affect the appearance, so attention should be paid to the selection.
Second measurement: measure the size of the stone. So as not to affect the splicing or cause the patterns, patterns line Deformation affects the decorative effect.
Three listening: listen to the knocking sound of stones. Generally speaking, the stone with good quality, dense and uniform inside and no micro cracks has a clear and pleasant knocking sound; On the contrary, if there are micro cracks or fine veins in the stone, or the contact between particles becomes loose due to weathering, the knocking sound will be rough and dumb.
Four tests: use simple test methods to check the quality of stone. Usually, a small drop of ink is dropped on the back of the stone. If the ink is quickly dispersed and leached everywhere, 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, it means that the stone is dense and of good quality.
Finished products in process board In terms of selection, since the raw materials of stone are natural, it is impossible to have the same texture, and the level of technology in mining and processing is also different. Most stones are graded. Granite Stone has no color stripe, most of them have only color spots, and some are solid colors. The finer the mineral particles, the better.
