1. Good corrosion resistance
stone mountain carving is a good corrosion-resistant material, and it has good resistance to air, water, and general concentrations of acids, alkalis, salts, and various oils and solvents. It has been applied to all aspects of chemical anticorrosion, and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.
2. Good electrical performance
is an excellent insulating material
3. Light weight and high strength
The relative density is between 1.5~2.0, only 1/4~1/5 of carbon steel, but the tensile strength is close to or even exceeds that of carbon steel, and the specific strength can be compared with high-grade alloy steel. Therefore, it has good results in aviation, rockets, spacecraft, high-pressure vessels and other products that need to reduce their own weight. The tensile, bending and compressive strength of some epoxy stone carvings can reach more than 400Mpa. The density, strength and specific strength of some materials are shown in Table 1-1.
Used to make insulators. It can still protect good dielectric properties at high frequencies. It has good microwave permeability and has been widely used in radar radomes.
4. Good thermal performance
The thermal conductivity of Shishan sculpture is low, 1.25~1.67kJ/(m·h·K) at room temperature, only 1/100~1/1000 of that of metal, and it is an excellent thermal insulation material. In the case of instantaneous high temperature, it is an ideal thermal protection and ablation-resistant material, which can protect the spacecraft from being scoured by high-speed airflow above 2000 °C.
① According to the needs, various structural products can be flexibly designed to meet the requirements of use, which can make the product have a good integrity.
②Materials can be fully selected to meet the performance of the product, such as: corrosion-resistant, instantaneous high-temperature resistant, particularly high-strength in a certain direction of the product, good dielectric properties, etc. can be designed.
③The molding process can be flexibly selected according to the shape, technical requirements, usage and quantity of the product.
④The process is simple, it can be formed at one time, and the economic effect is outstanding, especially for products with complex shapes and small quantities that are not easy to form, its process superiority is more prominent.
