The market for stone crafts requires a wide range of companies, and it is not easy to make a cast copper stone sculpture. If you want to make good cast copper and stone carving products, you must control every step of the stone crafts production process in a timely manner. stone crafts are divided into round sculptures and relief sculptures. Making stone sculpture is difficult. Flexible use of stone carving production methods can naturally design relief patterns.
The density of stone crafts is between 1.5 and 2.0, which is only 1/4 to 1/5 of carbon steel, but the tensile strength is close to it, exceeding that of carbon steel, and the strength can be compared with carbon steel. Therefore, it has very good results in aerospace vehicles, pressure vessels, and other products that need to reduce their own weight. The stretching, bending and bonding strengths of some epoxy resin FRP can reach over 400Mpa.
Stone crafts FRP is a good corrosion-resistant raw material, with good resistance to air, water, general concentrations of acids, alkalis, salts, and a variety of raw oils and solutions. It has been used in various fields of chemical anti-corrosion and has replaced carbon steel, stainless steel plates, wood, rare metals, etc.
Stone crafts are good insulating materials and are used to produce insulation. Excellent dielectric properties can still be maintained at high frequencies. Microwave heating has excellent permeability and has been widely used in radar radomes.
The thermal conductivity of stone crafts FRP is low, 1.25~1.67kJ/(m·h·K) at normal temperature, only 1/100~1/1000 of metal, and it is a good thermal insulation material. Under the premise of instantaneous high temperature, it is an ideal thermal protection and ablation-resistant material, which can protect spacecraft from being washed by high-pressure gas above 2000°C.
1. stone crafts can be designed with strong creativity
①Stone crafts can flexibly design many structural products according to needs to meet the needs of use, making the products very comprehensive.
② stone crafts can fully select materials to meet the performance of the product, such as being able to produce corrosion-resistant, instantaneous high-temperature resistant, particularly high-strength and better dielectric properties in a certain position of the equipment, etc.
2. The technical performance of stone crafts is of high quality
① stone crafts can flexibly select the molding method according to the product's form, technical standards, main uses and total volume.
② stone crafts are simple in process and can be formed at one time, with outstanding economic benefits. Especially for products with complex shapes and small quantities that are not easy to form, the advantages of its processing technology are highlighted.
