Refractory fiber classification and the main purpose
As can be seen from the growth rate of development, refractory materials industry development model is transition to industrial restructuring and upgrading of the past, the simple pursuit of productivity growth is no longer fit the market trend. National policy to promote industry consolidation, clearly put forward to eliminate backward production capacity, enhance industrial concentration, the formation of 2-3 leading enterprises. China's refractory enterprises, small and scattered state will be eased, as of **, China's strategic development of new industries and advanced high-temperature industry to promote advanced technology for China's refractory industry optimization and upgrading, structural adjustment and sustainable development provides an opportunity. Due to different industries, different enterprises, different production lines for refractory materials vary widely, and as of ** steel, cement, glass and other industries in the procurement and construction of refractory materials, the overall contracting has gradually become the mainstream model, supporting the products of refractory suppliers Diversification of varieties, on-site construction level and application of technical support and other aspects of higher requirements, forming a higher technical barriers. At the same time, the development of high-temperature industry promotes the technical progress and industrial upgrading of the refractory industry, and puts forward higher requirements on the continuous R & D capability of refractory enterprises. High-temperature industries such as steel, cement and glass are developing towards large-scale and centralized production. Production capacity is gradually concentrated in a few leading enterprises. The use of refractory materials has a great impact on the quality of high-temperature industrial products. Therefore, the selection of relevant refractory products by large enterprises Very cautious, usually takes a long time to verify, only companies with sufficient size and technology to become its long-term supplier.
Net reported @ ** years, the global refractory fiber market reached 3.87 billion US dollars (about 24 billion yuan), with the continuous improvement of the requirements of industrial specifications and different terminal industries to the protective fire protection products increased demand is expected to ** Year, refractory fiber market will increase to 5.036 billion US dollars (about 31.24 billion yuan), during the compound annual growth rate of about 5.4%. Regionally, Europe will become the largest regional market for refractory fibers in the world, followed by the North American market. However, due to the accelerated industrialization process, especially the development of oil and gas, infrastructure promoted the growth of demand, the demand for refractory fiber in South America will grow at a much faster rate than that of Europe and North America in the period of ** - **. At the same time, the demand for refractory fiber in the Asia Pacific region will also grow steadily in recent years. In addition, the R & D investment in novelty products will also further promote the demand for refractory fiber. From the suppliers, by the year of 1982, DuPont, Milliken, Royal TengKate, Japan Zhong Yuan, Solvay Group and Japan Teijin will become the world's leading refractory fiber suppliers.
In the increasingly scarce national resources today, the new green and energy saving has become the purpose of refractory development. During the "12th Five-Year Plan" period, the development of refractory materials presents new characteristics based on the improvement of product quality and application level. The emphasis is on adding or strengthening new connotations, that is, energy conservation, environmental protection and low carbon. Refractory materials science and technology development is the basic direction of independent innovation as the basic starting point, take the refractory design and application of scientific, production, application of refined and green, consumption reduction and resource saving integrated road to promote research and development and then To a new level. Among them, the innovation direction of refractory in cement industry is chromium-free and energy-saving. China's refractory industry's overall level of development from the advanced "green" there is a certain distance. "Green" refractories have attracted the attention of refractories and related industries. Relevant government departments and industry associations have also formulated corresponding policies and measures to encourage and promote the greening of refractory materials.
"2017 edition of China refractory market research and development prospects forecast report on the refractory market analysis from big to small, from macro to micro, based on the data, in-depth analysis of the refractory industry in the market positioning, refractory materials Industry development status, refractory market dynamics, refractory key enterprises operating conditions, refractories related policies and refractory industry chain impact.
The 2017 China Refractory Market Research and Development Forecast Report also presents to investors comprehensively the current status of major refractories and refractories related projects, the potential for future development of refractories, access to investment in refractories, and the risk of refractories Control, and respond to risk measures.
Refractory fiber can also be called ceramic fiber, which belongs to fibrous insulation refractory material. Refractory fiber with general characteristics of the fiber, such as soft, flexible, have a certain tensile strength, you can further process it into a variety of paper, wire, rope, belt, blanket and felt and other products. Has been widely used in metallurgy, chemical industry, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.
First, refractory fiber classification
Refractory fiber is divided into amorphous (glassy) and polycrystalline (crystalline) two categories. Amorphous refractory fibers, including aluminum silicate, high purity aluminum silicate, chromic aluminosilicate and high alumina refractory fibers. Polycrystalline refractory fibers, including mullite, alumina and zirconia fibers. (Table 1) are also classified according to the maximum allowable temperature of fire-resistant fibers.
Second, the main purpose of refractory fiber
1, refractory fiber for a variety of industrial furnace kiln insulation door seal, furnace curtain.
2, high temperature flue, duct bushing, expansion joints.
3, refractory fiber for petrochemical equipment, containers, pipes, high temperature insulation, insulation.
4, protective clothing under high temperature environment, gloves, hoods, helmets, boots and so on.
5, refractory fiber Suitable for automobile engine heat shield, heavy oil engine exhaust pipe package, high-speed racing composite brake friction pad.
6, conveying high temperature liquid, gas pumps, compressors and valves used for packing, gasket.
7, refractory fiber suitable for high temperature electrical insulation.
8, fire doors, fire curtains, fire blanket, then sparks with mat and insulation cover fire seams.
9, refractory fiber for aerospace, aviation industry with insulation, insulation materials, brake friction pad.
