Rust stone belongs to a kind of granite. The national cultural stone number is G682, the hardness is high, the compression resistance is 123.3Mpa, the bending resistance is 16.9Mpa, the water absorption rate is 0.16%, and the density is about 2.7~2.8 tons/m3. The rust stone is mainly of odorless, black spots, rust spots, and rust points. The high quality smooth yellow rust stone is considered to be the preferred stone type for the outer wall dry hanging, burnt noodles and lychee noodles. The paved stone and landscape stone that are processed are the favorite choices of landscape architects.
The polished surface of the rust stone is particularly beautiful, which shows the luxury and high wear resistance, which is favored by the majority of European and American customers. However, the shortcomings of rust stone are also obvious. The color difference is large. The large-scale production may have different chromatic aberrations, which affects the overall effect of the decoration. It is especially important to pay attention to the dry wall of rust stone. The rust stone is unstable due to its color difference. Sex, quotes are subject to the actual sample provided.
The varieties of rust stone are: "yellow rust stone, white rust stone, red embroidered stone, golden sand yellow, natural surface, mushroom stone, roadside stone, shaped stone, rust stone burning board, natural mushroom stone, rust stone board, rust stone Litchi surface, engineering board, large-size sheet, etc. It can be used for surface processing such as polishing, matt, fire, machine planing, lychee, mushroom, etc. The ore color is pure, the color difference is small, it is pure natural surface, no radiation. The material is absolutely harmless to the human body. It is the best for indoor and outdoor decoration and landscaping.
Rust stone processing method points:
1. Three-dimensional shaped cultural stone products: including three-dimensional portraits, animals, abstracts, and other stone sculptures with themes or shapes, plane reliefs, carved pillars, stigmas, column seats, carved furniture, railings, stone fireplaces, flower pots Vases, tombstones, fountains, engraved window covers, crafts, etc. It can be a regular symmetric product or an irregular asymmetric product.
2, plane shaped cultural stone products: such as kitchen and bathroom countertops, conventional cultural stone lines, waterjet parquet, workbench panels and tabletops, conventional roadside stones, corners, etc., the shape can be symmetrical It can also be asymmetrical.
3, curved sheet products: such as curved plates, cylinders, curved lines of regular curvature, etc., the shape is basically symmetrical. The processing of curved shaped shaped cultural stone is relatively simple (it will be more difficult than flat shaped cultural stone), mainly through simple processing such as cutting, grinding and throwing, but its equipment is advanced and is specially used to process curved sections. (For example, a diamond wire saw), which is mainly machined.
Since the current regulations have no relevant regulations for the use of such cultural stone in building curtain walls, the above-mentioned projects in China have carried out expert argumentation and proposed corresponding technical measures.
The strength of the yellow rust stone culture stone is an important indicator of the strength of the cultural stone. The average value of the bending strength test of the igneous rock (including granite) is not less than 10N/mm2, and the bending strength of the rust stone in Shandong is less than 8 When N/mm2, the batch of cultural stone should not be used in the curtain wall; other cultural stone fm should not be lower than 4 N/mm2. When the bending strength of the specimen is less than 3 N/mm2, the batch of cultural stone should not be in the curtain wall. application.
Sedimentary rocks sometimes have inconsistent strengths in all directions. At this time, the strength along the main direction of the cultural stone panels should meet the above requirements. After the culture stone has undergone freeze-thaw cycles, the strength is reduced. The freeze-thaw cycle test of rust stone is carried out according to the national standard GB9966.2. The ratio of the strength to the original strength after the freeze-thaw cycle is called the freeze-thaw coefficient. The cultural stone used for the curtain wall should have a freeze-thaw coefficient of less than 0.8.
