Natural marble is the first choice for many people for its high-end atmosphere and beautiful appearance. However, many people do not understand stone. There are so many types of stone on the market. Many stone sellers will tell you that their stone is natural. Is that so? Foshan White Marble Stone is a naturally formed curtain wall material, and the same stone of the same color system will also have color differences. This article introduces the control methods of stone color difference, from design, mining, processing technology to stone curtain wall installation and protection, and makes a more detailed introduction. 1. Stone curtain wall Stone curtain wall is usually composed of stone slab supporting structure, and it is a building envelope structure that does not bear the load and function of the main structure.

Stone curtain walls generally adopt the installation method of dry hanging, because the cost of dry hanging is slightly higher than that of wet paste, but there are some advantages. Dry hanging has high safety and reliability, and it is not easy to fall, so dry hanging is used for higher walls. But the most nerve-wracking thing about the stone curtain wall is its color.

In severe cases, it will even seem to be full of patches, lowering the grade of the building. Aiming at this feature, many improvement schemes have been proposed in the industry. Natural marble table 2. Conventional color difference control In procurement, it is generally avoided by purchasing stones from the same mine and the same batch.

Technically, pre-assembly and typesetting are used to ensure the uniformity of the stone color of the main facade. However, the above scheme not only increases the workload, but also treats the symptoms rather than the root cause. Only by controlling the source can the curtain wall achieve the effect of zero color difference! Touch-ups and color changes. Method 1: Color enhancement is to enhance the original color of the stone to make it more beautiful and dense.

Method 2: Polishing is to make the stone more delicate, moist, bright and beautiful without changing the original color of the stone. Method 3: Color change is to add a change to the unpopular stone with poor material color, so that it becomes a color that is popular in the market. Some manufacturers have this technology, but many parties want to pursue stone. The natural texture is often very repulsive in this way. The color of the stone is mainly determined by the color of the minerals it contains.

There are three main colors of minerals in general stone: other colors, self-colors and false colors. Other colors are the colors formed after the colored impurities contained in the mineral materials are mixed. Self-color is the color of the mineral itself, that is, the color of the ions that make up the mineral itself.

False color is the color shown by the interference of light waves caused by the oxidation or decomposition of the surface of the ore. 4. Stone coloring method The processing of stone color is to change the stone by using three color processing methods according to the mechanism of forming stone color. At present, there are mainly three processing methods, namely physical coloring method, chemical coloring method and physical and chemical coloring method.

Physical coloring method: mainly by adding different minerals to change its color. Chemical coloring method: In order to introduce pigments into the interior of the stone and make it chemically react with the internal substances to achieve the purpose. Physical and chemical method: through the physical substance participation and the chemical pigment introduction reaction, the stone material can be changed in color.

The marble material is mainly composed of calcium carbonate, and it also contains magnesium carbonate, calcium oxide, magnesium oxide, etc. When the air is humid and contains sulfur dioxide gas, the surface of some marble varieties will undergo a chemical reaction to form gypsum, showing a strong weathering phenomenon. Marble is mainly composed of carbonate minerals, especially calcareous carbonate, which has the most content and is easily corroded by acidic substances, which can preserve the beauty of color and pattern for a long time.

Marble generally has low hardness, poor wear resistance, generally small grains, uneven color, large changes, texture, stains, impurities, etc. It is suitable for interior wall decoration of buildings, and when used for laying floors Protective measures against abrasion should be taken. Therefore, the biggest difference between natural marble and artificial marble is that natural marble has more or less crack-like stripes, and the lines are unnatural.
