China's stone reserves are great, but the exploitation of raw material consumption is a big stone, stone belongs to a class of non-renewable resources, unlimited greed of mining waste is our demand on nature, whether it can be recycled stone ?
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 valuable 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 some 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, people are demanding more and more specifications for various stone varieties. 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.
China is a large stone producing country in the world. The output of stone covers almost half of the total output of the earth. However, under such a fascinating and proud appearance, the development of the stone machinery industry is not optimistic. 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 continue to develop with “environmental protectionâ€, “qualityâ€, “efficiency†and “energy savingâ€. 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 needs us to work together to maintain the stone industry. The stone industry is a necessary means of development.
Application
Cement Basket is an isolation device, used for preventing cement slurry from sedimentation due to being displaced with drilling fluid, during the cementing process of suspended cementing interval.
Installed at the bottom of suspended cementing interval, it supports cement in annulus to avoid or reduce the loss of cement slurry and protect the weak formation structure so as to prevent excessive static pressure generated by the weight of cement string.
It is usually installed on the casing string above the weak formation structure, but also used during stratified cementing and surface cementing. Each metal fin on the cement basket provides maximum flexibility and fluid flow passage at the same time of maintaining the optimized supporting characteristics.
