Natural decorative stone is made of natural stone, so its quality depends on the quality of the block on the one hand, and on the other hand. Inferior marble and granite slabs are mainly represented in the following aspects:
1) The surface of the pattern is not beautiful
The surface texture of the high-quality stone is beautiful and elegant, making the decorative surface have a strong decorative effect. However, the quality of the stone after processing is not beautiful, and it can not give people a beautiful enjoyment. Therefore, the surface tone of the stone is the main indicator for evaluating the quality of the stone.
2) The quality of the processed sheet is poor.
Stone will leave some defects on the surface appearance during the processing. If these appearance defects are beyond the scope of national standards, stone is a non-conforming product. With these poor quality stone with poor appearance, the overall effect will be very poor. Therefore, in judging the quality of the stone, in addition to considering the color of the pattern, the appearance quality must also be checked.
3) The deviation of the size of the specification is large
The decorative stone is processed into a sheet, and is constructed by using a tile or a collage method. If the plate with a large deviation of the specification size is laid, the surface will be uneven and the seams will be uneven. Especially for the decoration of the facade, the line shape of the decorative surface will be irregular, which will affect the overall decorative effect. Therefore, the deviation of the size of the specification will directly affect the decorative effect of the stone.
4) poor physical and chemical performance indicators
The inferior stone has poor compressive strength, flexural strength, wear resistance, durability, hardness, etc., and cannot guarantee the durability of the stone.
