What are the composition materials of stone mountain carving?

stone mountain carving material is a new type of material developed abroad in the early 20th century. It has the characteristics of light weight, high strength, anti-corrosion, heat preservation, easy molding, easy coloring, and long life. Its density is 1.5-2.0g/cm3, 3-4 times lighter than steel, and its specific strength is 1.7 times higher than steel, with good mechanical and physical properties.

First of all, stone carving is mainly made of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin as the matrix.
Its corrosion resistance mainly depends on the performance of the resin, so it is usually because the corrosion resistance of Stone Carving itself is very good, so many common products and equipment in life are made of stone carving. For example, stone carving septic tanks, stone carving cooling towers, stone carving water tanks, stone carving pipes, etc., are usually used for waste heat wastewater in production and life, and are used to treat waste heat wastewater in life. The equipment was tested for corrosion resistance due to year-round exposure to certain pollutants. From the beginning of research and development, stone mountain carving has been widely used in various equipment.
Flat-knife block surface method: It is mainly to cut out the outline and structure of the work with a large flat-knife surface when chiseling the blank, so that it can produce a rough and powerful cutting feeling with an ax and a knife. Therefore, the knife must be stable, accurate, and ruthless. It must be powerful, consistent with the knife and knife, cool and not greasy, and make each knife explain the problem and achieve the final effect of the work. The application process of the flat knife block surface method is actually to use simple abstract geometric shapes to summarize the shapes of various complex shapes. Process, this process can reduce every shape, every piece of bone, and muscle into large and small squares, rectangles, trapezoids, and rhombuses. Therefore, the author is required to have solid modeling skills and the ability to generalize natural shapes. The surface method can be combined with some round knives throughout the whole process of carving to form the final artistic effect, or it can only be used in the primary stage of carving for large-scale processing, and then use other knife methods to make richer and more delicate shapes from square to round portray.
Of course, the corrosion resistance of stone mountain carving is mainly due to its reasonable selection and crosslinking density of resin. So, in the whole process, what are the three main factors of temperature, concentration and resin, in fact, usually, it is determined according to different situations. The characteristics are also different for different resins. In terms of corrosion resistance: phenolic acid has better solvent resistance, amine curing has better alkali resistance, polyester has better comprehensiveness, and different resins have different corrosion resistance.
stone mountain carving materials are composed of high-chroma surface layer, strength layer, support layer, strength layer and other multi-layer composites, including advanced high-strength materials, high-performance polymers, metal frame materials and other materials. Among them, the high-chroma surface layer is added with ultraviolet absorbers, and the QUV artificial aging test can reach 1000 hours, which is equivalent to 10 years of aging in the natural environment. Using high weather resistance coating, the coating life can reach 20 years, the color retention rate within 10 years is not less than 90%, and the color difference △E is not more than 4%.
