1. Chopped basalt fiber Basalt fiber is a kind of inorganic fiber material. Chopped basalt fiber is an inorganic mineral fiber with a length of less than 50mm and can be evenly dispersed in cement concrete. 2. Characteristics of chopped basalt fibers (1) The naturalness of raw materials. Because the raw material for producing continuous basalt fiber depends on the natural volcanic extrusive rock, there are no ingredients harmful to human health except that it is inherently high in chemical stability and thermal stability. (2) Comprehensive performance. Basalt fiber is acid resistant and alkali resistant. It is both low temperature and high temperature resistant. It is insulated and insulated by heat and electricity. Its tensile strength is higher than that of large tow carbon fiber. Its elongation at break is even better than that of small tow carbon fibers. It has high compressive strength, shear strength and adaptability to aging, and has good comprehensive properties in harsh environment. (3) Low cost. The price of basalt fiber used in cement concrete is significantly lower than that of steel fiber and polyester fiber. (4) Natural compatibility. Basalt fiber is a typical silicate fiber, which is easy to disperse when mixed with asphalt concrete, cement concrete and mortar. The newly mixed basalt fiber concrete has stable volume, good workability and durability, and has superior high temperature resistance, anti-seepage, crack resistance and impact resistance.
1. Basalt short fiber - a new material to replace steel fiber. Basalt short fiber is an inorganic mineral fiber with a length of less than 50mm, which can be evenly dispersed in cement concrete. 2. Characteristics of basalt short fiber (1) the specific gravity of steel fiber is 7.8 and that of cement concrete is 2.5. After mixing, the specific gravity of steel fiber is higher than that of cement, and the cement will sink and have poor dispersion. The specific gravity of basalt short fiber is 2.6, which is basically equivalent to that of cement concrete. After mixing, it does not sink, has good dispersion, is degradable, and is green. The road surface will not be as hard as steel fiber, resulting in car driving noise.. (2) Basalt staple fiber is a real "multifunctional" fiber. Acid and alkali resistance (especially alkali resistance, fully applicable to cement concrete), low and high temperature resistance, insulation and sound insulation. The tensile strength is three times that of steel fiber. The corrosion resistance of basalt fiber is better than that of steel fiber. The compressive strength is 20% higher than that of steel fiber, which is suitable for harsh environment. It has excellent comprehensive performance. (3) Low cost. The price of basalt fiber used in cement concrete is significantly lower than that of 50% steel fiber. (4) Natural compatibility. Basalt fiber is a typical silicate fiber, which is easy to disperse when mixed with cement concrete and mortar. Fresh basalt fiber concrete has stable volume, good workability and durability, and has excellent high temperature resistance, impermeability, crack resistance and impact resistance.
Produced by Chongqing Hesheng Longgang Technology Co., Ltd. (manufacturer) Basalt fiber reinforcement (new material to replace reinforcement) Product Description: basalt fiber reinforced bar (BFRP) is a new composite material formed by pultrusion process. It is made of basalt fiber as reinforcement, resin, filler and curing agent. Now it has been widely used in construction, highway and bridge constructionã?? Basalt fiber reinforcement can completely replace ordinary steel reinforcement and deformed steel; Compared with ordinary reinforcement, it has strong advantages: (see Annex for technical parameters) 1. The cost is the same as that of ordinary reinforcement; 2. The strength is 200% of the ordinary reinforcement with the same specification and diameter; The tensile strength reaches 1100mpap; The reinforcement is only 450MPa, 3. Basalt fiber reinforcement, especially with high acid, alkali and corrosion resistance, is a kind of electrical insulator that will never rust. 4. Basalt fiber reinforced bar, which is non-magnetic. It has high tolerance to the moisture concentration in cement mortar and the penetration and diffusion of carbon dioxide, and can prevent the corrosion of concrete structure in harsh environment, so as to improve the durability of buildings and bridges. 5. The specific gravity of basalt fiber reinforcement is 2.1g/cm3; The specific gravity of steel and reinforcement is 7.85/cm3; The diameter weight of the same specification is 370% lighter than that of steel reinforcement, and the strength is 200% of that of steel reinforcement. 6. The physical properties of basalt fiber reinforcement are higher than that of steel reinforcement, and the cost is the same as that of steel reinforcement, which is of epoch-making significance to replace steel reinforcementã??
The graphite electrode comprises: (1) Regular power graphite electrode( RP grade Graphite Electrode) . Graphite electrode with current density less than 17a / cm2 is allowed to be used in common power electric furnaces for steelmaking, silicon smelting and yellow phosphorus smelting. (2) Oxidation resistant coating graphite electrode. A graphite electrode coated with an anti-oxidation protective layer (graphite electrode anti oxidant). The formation of both conductive and high temperature oxidation resistant protective layer can reduce the electrode consumption (19% ~ 50%), prolong the service life of the electrode (22% ~ 60%), and reduce the electric energy consumption of the electrode. The popularization and application of this technology can bring such economic and social effects as follows: 1. The unit consumption of graphite electrode is less, and the production cost is reduced to a certain extent. For example, according to the consumption of 35 graphite electrodes per week and 165 refining heats of LF refining furnace in a steel-making plant without shutdown in the whole year, 373 (153 tons) electrodes can be saved every year by using graphite electrode oxidation resistance technology, and RMB 2585700 can be saved by RMB 16900 per ton of ultra-high power electrode per year. 2 The graphite electrode consumes less electricity, saves the unit electricity consumption of steelmaking, saves the production cost, saves energy! 3. Because the graphite electrode is replaced less times, the labor amount and risk coefficient of operators are reduced, and the production efficiency is improved. 4 Graphite electrode is a high consumption and high pollution product, which has a very important social significance in the days of promoting energy conservation, emission reduction and environmental protection. This technology is still in the stage of research and development in China, and some domestic manufacturers have begun to produce it. It is widely used in Japan and other developed countries. At present, there are also companies that import the anti-oxidation protective coating in China. (3) High power graphite electrode (HP grade Graphite Electrode). Graphite electrode with current density of 18-25a / cm2 is allowed to be used in high power electric arc furnace for steelmaking. (4) Ultra high power graphite electrode( UHP grade Graphite Electrode). Graphite electrode with current density greater than 25A / cm2 is allowed. It is mainly used in ultra high power EAF.
