Rust stone granite can do what processing
Apr 14, 2021
Rust stone stone is a relatively common granite stone products in China, which is very widely used, so there are many types of processing. Let the following Xiaobian share with you several processing methods of rust stone:
1, Three-dimensional abnormal culture stone products: including three-dimensional people, animals, abstract, and other themes or modeling of stone products, flat relief, with carved columns, columns, columns, carved furniture, handrails, stone fireplace, flower pot vase, tombstone, fountain, with carved window cover door, handicrafts and so on.It can be a regular symmetrical product, or it can be an irregular asymmetric product.
2, Plane shaped cultural stone products: such as kitchen and bathroom table panel, conventional cultural stone lines, water knife parquet plate, table panel and desktop, conventional roadside stone, corner and so on, its shape can be symmetrical, can also be asymmetric.
3, Curved plate products: such as arc plate, cylinder, regular radian curve lines, etc., the shape is basically symmetric.Surface special-shaped cultural stone processing is relatively simple (will be more difficult than the plane special-shaped cultural stone), mainly through cutting, grinding, throwing and other simple processing is completed, but its advanced equipment is specially used to process the curve section (such as diamond rope saw), which is mainly completed by machine processing.
Because the current code for such cultural stone for building curtain wall has no relevant provisions, so the domestic above projects are respectively carried out expert demonstration, put forward the corresponding technical measures.
The strength of yellow rust stone fossils, as an important indicator of the strength of cultural stone is dry, and the average bending strength test Fm of igneous rock (including granite) should not be less than 10N/mm2. When the bending strength of Shandong rust stone is lower than 8 N/mm2, the approval of the fossil should not be used in the curtain wall;Fm of other cultural stones should not be lower than 4 N/mm2. When the bending strength of the specimen is lower than 3 N/mm2, the fossil of this approval should not be applied in the curtain wall.
Sometimes the strength of sedimentary rocks is not consistent in each direction, then the strength along the main force direction of the cultural stone panels should meet the above requirements.Culture stone after the freeze - thaw cycle, the strength is reduced.Rust stone freeze-thaw cycle test according to the national standard GB9966.2.The ratio of the strength after the freeze-thaw cycle to the original strength is called the freeze-thaw coefficient.The freeze-thaw coefficient of the cultural stone used for curtain wall should not be less than 0.8.
