1, the market opportunity
Humanity in the 21st century, the industrial structure will be adjusted to as information, biology, aerospace, marine development, as well as new materials and new energy-based high-tech and new materials industries will gradually grow. These high-tech and new materials industries and non-metallic mineral raw materials or mineral materials, closely related. Therefore, the high-tech and new materials industry in the 21st century, non-metallic mineral processing technologies and industrial development is one important opportunity.
Into the 21st century, the chemical industry, machinery, energy, automobile, light industry, metallurgy, building materials and other traditional industries will bring in new technology and the use of new materials, technical innovation and industrial upgrading. These technological progress and industrial upgrading and non-metallic mineral products closely related to deep processing. Therefore, the traditional industries of technological progress and industrial upgrading is the beginning of the century of China's non-metallic mineral processing technology and industrial development, one of the major opportunities.
Environmental protection is humanity in the 21st century, one of the major challenges facing, it is directly related to human survival and economic and social sustainable development. As human awareness of environmental protection and global environmental standards and requirements to improve environmental protection industry will become the 21st century's most important emerging industries. Many non-metallic minerals, such as diatomite row of stone, bentonite, attapulgite, sepiolite, etc. After processing (purification, surface treatment and composite) with a selective absorption of harmful and a variety of organic and inorganic pollutants function but also has material easy to get units to deal with low cost, own wood secondary pollution and so on. Therefore, the environmental protection industry in the 21st century, China's non-metallic mineral processing technologies and industrial development is another important opportunity.
2. Technical challenges
Non-metallic Minerals Industry in China in the 21st century on the threshold of good opportunities as well as facing severe technical challenges. These challenges are mainly the market for non-metallic mineral products purity, particle size and distribution characteristics, particle shape, surface and interfacial properties, functional requirements, etc., as well as the state's resources to improve the comprehensive utilization and environmental protection requirements increase.
The first is the market demand purity non-metallic mineral products will be increased. In many cases this means the purity of mineral composition, rather than the sense of the purity of the chemical composition of minerals or chemical elements in the sense of purity. Because the vast majority of non-metallic mineral value lies in its physical and chemical properties rather than its chemical elements, but the non-metallic minerals only after purification of its physical and chemical properties in order to fully reflect and play.
Therefore, the century of both the new high-tech and new materials industries, the environmental protection industry, or paper, paint and other traditional industries are non-metallic mineral products will be put forward higher requirements on the purity. With the purity requirements of non-metallic mineral products increased the difficulty of dressing purification techniques will also increase, while the depleted resources, and resource comprehensive utilization rate of increase in demand will also increase the difficulty of mineral purification techniques.
Secondly, the market size and distribution of non-metallic mineral products characteristic requirements increase. As the ultra-fine powder with a large surface area and high surface activity, chemical reaction speed, low sintering temperature and sintered high strength, filling reinforcement of good performance, covering high rate of excellent physical and chemical properties. Many application areas, such as microelectronics, paper, paint, engineering plastics, degradable plastics, rubber cables, adhesives, advanced ceramics and refractory materials, ceramic glazes, fine abrasive such as the fineness of the non-metallic mineral requirements increase; in some areas also non-metallic mineral products particle size distribution to be more stringent requirement that not only requires ultra-fine grain size and requires a narrow particle size range.
More challenging is the beginning of the 21st century domestic and foreign markets ultra-fine powder of various types of non-metallic mineral products, demand will significantly increase the domestic demand is expected in 2005 will reach around 1.4 million t, export volume will reach 400,000 t so; in 2010 the domestic demand and export volume will reach 2 million t and 700,000 t around. The increasing demand for ultra-fine powder and particle size distribution requirements of the improvements require development of efficient, large-scale ultra-fine grinding equipment and a good classification accuracy, classification and efficient large-scale fine grading equipment, and the corresponding ultra-fine powder processing technology .
The third is a body of non-metallic mineral powder particle shape product demand increase. Natural crystal body of non-metallic mineral powder products have a unique application performance, such as a sheet of paper coating kaolin with excellent cover rate and smoothness, with mica flakes as raw material, manufactured mica pearlescent mica and colored with excellent optical performance, needle-like wollastonite, and tremolite particles, mica flakes, talc and other sheet reinforced with excellent filling properties, polymer matrix composites can enhance the mechanical strength. So the market for non-metallic mineral powder body products, in particular, mica and wollastonite particle shape will make higher demands. China is still not stable and high-volume production overseas have been able to a large number of stable production of high aspect ratio (15-20: l) needle-like wollastonite products and large radius to thickness ratio (70-80: l) and high surface finish white mica.
The fourth is the nature of non-metallic mineral surfaces and interfaces required further improvement. Non-metallic mineral products specific to the surface and interface properties, such as high specific surface area and surface activity, porosity and strong adsorption, ion exchange, etc. are widely used in its one of the main. Many application areas there are special requirements on their surface properties, such as polymer matrix composite materials (plastics, rubber, adhesive, etc.) require non-metallic mineral filler surface and polymer molecules have a good compatibility, multi-phase ceramic material requirements various inorganic components have good dispersion and compatibility, the petrochemical industry with the zeolite and kaolin catalyst or carrier must have a specific pore size distribution and high surface area, 4A molecular sieves have a certain amount of calcium ion adsorption capacity, oil refining decoloration using activated clay (bentonite), and the beer filtration using diatomaceous earth to have a strong adsorption capacity. Therefore, the early 21st century will be non-metallic mineral surface modification and composite technology, equipment and higher requirements.
The fifth is a functional non-metallic mineral products more specific and higher requirements. Unique features of the modern non-metallic mineral materials, one of the important features, but also in modern high-tech and new materials industries, widely used one of the reasons. With high-tech and new materials industries, further development of non-metallic mineral products related applications will be made more specific functionality and higher requirements.
