Stone Garden Statues generally have an outdoor lifespan of 8-10 years, but of course there are requirements for production. The required quantity of stone sculpture and the thickness and symmetry of the entire stone sculpture must be achieved. The paint on the surface protective layer also has a lot to do with it. If general nitrocellulose paint is used outdoors, it is estimated that the surface color will need to be repaired in less than two years.
The material of the Shiyuan statue is stone sculpture reinforced plastic. It uses stone sculpture and their products (
stone carving cloth, belts, felt, yarn, etc.) as reinforcing materials. It is a composite material with synthetic resin as the matrix material. The concept of composite materials means that one material cannot meet the requirements of use, and two or more materials need to be combined together to form another material that can meet people's requirements, that is, composite materials.
For example, although a single type of stone sculpture has high strength, the fibers are loose and can only bear tensile force, but cannot bear bending, shearing and compressive stress. It is not easy to make a fixed geometric shape and is a soft body. If they are bonded together with synthetic resin, they can be made into various hard products with fixed shapes, which can withstand not only tensile stress, but also bending, compression and shear stress. This makes up the stone sculpture-reinforced plastic matrix composite.
Because its strength is equivalent to steel, it also contains stone carving components, and it also has the color, shape, corrosion resistance, electrical insulation, heat insulation and other properties of stone carving. Like stone carving, it formed the easy-to-understand name "Shiyuan Statue" ', this term was proposed by Comrade Lai Jifa, the former Minister of the Ministry of Building Materials Industry, in 1958. Expanding from the building materials system to the whole country, the meaning of Stone Garden Statues refers to reinforced plastics in which stone sculpture are used as reinforcing materials and synthetic resins are used as binders. Foreign countries call them stone sculpture reinforced plastics.
With the development of my country's stone garden sculpture industry, the plastic-based reinforcing materials have expanded from stone sculpture to carbon fiber, boron fiber, aramid fiber, alumina fiber and silicon carbide fiber. Undoubtedly, reinforced materials made of these new fibers Plastics are some high-performance fiber-reinforced composite materials, which cannot be summarized by the common name of Stone Garden Statues. Taking into account the historical origin and development, Stone Garden Statues composite materials are usually named as such.
