Really stone paint natural colored sand type and origin

Really stone paint domestic manufacturers to use the color sand materials are almost natural colored sand, far more than the consumption of colored sand and burn with sand. Natural color sand as really stone paint is the most important raw materials, its application and development status also affects the really stone paint the future application and development prospect. Natural colour sand are composed of granite or marble natural ore enrichment, crushing, crushing, grading, sand mixing, packing and so on all kinds of craft products made of granular or powder. Can be used for building decoration, terrazzo, aggregate, really stone paint, color sand paint, floor paint, etc. It is non-toxic, tasteless, corrosion resistance, high hardness, wear resistance, etc. In terms of material composition, natural color sand is usually granite or marble. However, these two kinds of rocks have obvious differences. Granite is technically known as acid crystallization plutonic rock, is the most widely distributed in igneous rocks. It is composed of feldspar, timely and mica. The main composition of silica, accounting for 65% ~ 75%. The appearance is given priority to with dot, dense rock hard. The content of silica and feldspar determines the nature of the stone. In general, it has good stability, strong weatherability, low prices, but relatively high in some radioactive minerals. Therefore, it is widely used. Marble is mainly composed of calcite, limestone, serpentine and dolomite. The appearance of it mainly stripe pattern. It is a hard material, usually contains about 50% of the calcium carbonate, and mixed with magnesium carbonate, calcium oxide, manganese oxide and silicon dioxide. This component makes the material in carbon dioxide in the atmosphere, carbide and under the action of water vapor easy weathering and dissolution, lead to lose its luster. Marble is usually not containing radioactive substances, and relatively expensive. When used in exterior wall decoration, should choose granite materials, as far as possible to consider the durability and cost, stone or colored sand. Compared with the special-shaped stone, the value of natural colored sand is much lower, can be processed into natural colored sand ore material is generally gravel stone processing scrap materials and mining process, so the cost is very low. Cost mainly comes from ore transportation and colored sand processing cost, which determine the place of natural colored sand production must be close to the color sand exploration area, a variety of colored sand has obvious regionality. Really stone paint used in the natural color sand is usually based on the color sand color into white, red, yellow, green, and blue, gray and black. Like white pigment application in coating, white natural color sand most used in really stone paint. Dali bai ( Also known as the white marble) And Snow White are two of the most common type, accounting for more than half of the total. These two kinds of sand is very rich in China. They in hebei, henan, shandong, anhui, guangxi and guangdong have a good supply of goods, low processing cost, price are relatively cheap, stable supply of goods. From the point of market reaction, hebei, guangxi is the production of white sand can be most really stone paint manufacturers, have high cost performance and stability. Gray and black sand is the best quality, the most stable in hebei taihang mountains of sand. Taihang black, black, China diamond varieties such as black, gray jade, black is commonly used. Red sand with the advantages of mineral resources close to henan, hebei, there are some special varieties, such as sand, chicken blood red sand, lotus red, Chinese red sand, sand, chrysanthemum golden sand sand, etc. It is widely used in production of really stone paint. Chrysanthemum yellow is a very bright yellow sand, has distinct characteristics. At the same time, because of low yield ( Only 30% ~ 35%) , low efficiency, Granite, hard, processing difficulties) , mineral resources nervous, It is understood that only produce hubei shiyan this ore) , the market price is much higher than ordinary sand texture. Guangdong yunfu has some recognized red and yellow varieties, but from the point of field investigation, the source of basic wasn't there. Yunfu is local, but yunfu is one of the world's leading international stone material distribution center. Some popular stable stone cutout ( Such as beige, wood grain yellow, tiger skin yellow, red, etc. ) 。 ) In recent years has become
