China's stone resources are very large, but the consumption of stone raw materials is also very large. Stone is a kind of non-renewable resources. Unrestricted waste is a greedy request for nature. Can stones be recycled? Nowadays, environmental protection is advocated, and some stones can be used elsewhere to avoid waste of resources.
According to the in-depth research report on the supply and demand prospects of China's stone furniture industry in recent years, it is shown from the perspective of economic technology that stone is not only superior in quality to other building materials, but also difficult to mine due to its hard stone quality. The cost is relatively high, and the repair processing and surface treatment requirements are high, the area per unit volume is large, the sawing and cutting cost is relatively high, and the processing cost per unit area is also relatively high, so the price is high, some valuable decorative stone Each square meter is worth thousands of dollars.
In addition, due to the decoration of the stone, especially the natural granite structure is dense, hard, acid, corrosion, wear, water absorption (less than 1%), high compressive strength (120 ~ 250MPa), frost resistance Strong, not easy to weather, good durability, long service life (100-200 years for coarse-grained granite, 500-1000 years for fine-grained granite), it is difficult to reach its ultimate service life in one use or even multiple cycles. .
At present, although plastics, ceramics and other building materials have been widely used, and seized part of the market of building materials decoration business, but because of its unique natural advantages, stone is still the material of choice for architectural decoration engineering. Especially with the vigorous development of the construction and decoration industry in China, stone has undoubtedly become the choice of outdoor landscape design and interior decoration. At the same time, the demand for various stone varieties and specifications is increasing. At the same time, the stone industry should implement scientific management, give full play to the advantages of its own industrial clusters, and improve the positioning of the industry and the market. The development of the domestic stone industry has a long way to go, and its core is closely related to its processing technology and manufacturing machinery.
Nowadays, the scale of domestic stone enterprises is uneven, which has caused disorderly competition among the domestic stone machinery industry and eventually led to a vicious circle. So, what kind of strategy is needed to improve this phenomenon? In addition to clarifying their own responsibilities and pressures, stone machinery enterprises must take “environmental protectionâ€, “qualityâ€, “efficient†and “energy saving†as their ultimate development goals, and improve products through scientific innovation and introduction of new technologies. The rate of materials will eventually achieve an overall improvement in the entire industry.
It can be seen that the reuse of stone can not only be environmentally friendly, but also reduce costs. This is in line with the core of the development of energy conservation and environmental protection that we are now advocating. The road to energy conservation and environmental protection that we are going to take now is still long. The ecological balance of the future requires us to work together to maintain the stone industry. The stone industry is a necessary means of development.
New trends in stone development: the stone industry will take the road of recycling

As a high-grade building decoration material, stone is widely used in interior and exterior decoration design, curtain wall decoration and public facilities construction. The stones commonly found on the market are mainly divided into natural stone and artificial stone and marble. Natural stone is divided into slate and granite according to its physical and chemical properties. Artificial stone is divided into terrazzo and synthetic stone according to the process. The terrazzo is forged from cement, concrete and other raw materials; the synthetic stone is made of natural stone gravel as raw material, and is pressed and polished with a binder. The latter two are made by hand, so the strength is not as high as natural stone. Stone is a high-grade product of architectural decoration materials. Natural stone is roughly divided into granite, slate, sandstone, limestone, volcanic rock, etc. With the continuous development and advancement of technology, the products of artificial stone are constantly changing, and the quality and beauty are not inferior to natural. Stone. With the development of architectural design, stone has already become one of the important raw materials for construction, decoration, roads and bridge construction.
