At present, 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. Unlimited waste is a greedy request for nature, then whether the stone can be recycled. Today, environmental protection is advocated, and some stones can be used elsewhere to avoid waste of resources.
From the perspective of economic technology, because stone is superior to other building materials, not only the quality of the stone itself is good, but also because of its hard stone, the difficulty of mining is relatively high, and the repair processing and surface treatment requirements are high. The size of the volume is large, the cost of sawing and cutting is relatively high, and the processing cost per unit area is also relatively high. Therefore, the price is high, and some precious decorative stone is worth thousands of yuan per square meter.
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 firms, 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 between the domestic stone machinery industry and eventually led to a vicious circle. Then, what kind of strategy is needed to improve this phenomenon? In addition to clarifying its own responsibilities and pressures, stone machinery enterprises must also adopt "environmental protection", "quality", "high efficiency" and "energy saving" as the ultimate development. The goal is to improve the product yield through scientific innovation and the introduction of new technologies, and ultimately achieve an overall improvement of the entire industry level.
It can be seen that the reuse of stone can not only be environmentally friendly, but also reduce costs. It 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.
