The reason why stone is used for the decoration of high-end buildings is to make full use of its excellent physical properties, especially its rich colors, which are unmatched by other materials. However, since the color of the stone is naturally formed, the quality of the color is determined by the pigment ions contained in the stone and the internal structure. The different order of formation of the different minerals that make up the stone will also affect the color change. This is what we call the color difference. In the process of decoration, the same place, the color of the stone is too large, will affect the overall aesthetics of the stone to a large extent, then the color difference of the stone may be caused by those factors? How should we prevent it? 365 Stone network analysis, the main factors are three aspects, the following is the analysis of its specific reasons and preventive measures:
1. After the manufacturer cuts the stone, it does not pre-type according to the drawing number. When the material enters the field, the acceptance is not strict. There is no plate with the grain reversed and the plate with larger color difference is selected.
Precautionary measures: When processing the stone under the factory, it is best to number each stone one by one, and the direction of the grain should be marked in the direction of the grain. To the manufacturers to do pre-typesetting to ensure the stone texture, uniform color requirements. After the materials arrive at the site, the materials are first unpacked and pre-packaged, and arranged according to the typesetting number, and the plates with uneven vertical and vertical patterns and uneven color shade are selected.
3. On-site workers did not follow the layout number according to the number construction.
Precautionary measures: If the material is pre-fabricated at the time of acceptance and no problems are found, the worker must construct according to the pre-package number during construction. If there is stone damage or graininess in the process, the color difference should be solved first by using the yellow sand pre-laying to ensure that the subsequent stone can continue to be laid, but do not stick firmly, and then replace it after the board is added. When paying the workers to the bottom, it is necessary to make it clear that the same specifications of stone are not constructed according to the number, and the plates with the color difference are resolutely not used. The quality inspector, the foreman should be diligent in the inspection to find the plate with large difference in texture.
4. Insufficient protection of the finished product on the site, resulting in the surface being soaked by water, contaminated, and caused by chromatic aberration.
Precautionary measures: For stone with softer stone material or holes with more ground material, after construction protection, pay attention to anti-foaming water. Do not use protective fabrics such as carpets, cardboards and straw curtains that are easy to fade. In order to avoid running water after work, soak the protective materials, pollute the stone, and cause color difference.
