We will continue to explore various application scenarios of basalt fiber, accurately explore the potential demand, accurately find the application point of "1+N" comprehensive advantages of basalt fiber, effectively solve the application problems, and effectively promote the scale of application fields. Simply put, it is to discover and realize the application value of basalt fiber.
Basalt fiber has better overall performance compared to E-type glass fiber. It has higher breaking strength and Young's modulus compared with glass fiber in the test of short-cut raw wire and coarse sand. At the same time, basalt fiber has the material advantages of UV resistance and electromagnetic radiation, which is conducive to the expansion of products in downstream applications. However, as the most widely used glass fiber species at present, E-type common glass fiber has a gap with basalt fiber in terms of performance. In addition, glass fiber has disadvantages in acid and alkali resistance and production gas emission, which is not conducive to the development of glass fiber.
Pumice is also a good abrasive material, used to grind metal and stone; in industry, it can also be used as a filter, drier, catalyst, etc. Basaltic rock formations are related to their consolidation environment. Basalt formed on land is often in rope structure, block structure and columnar joints; basalt formed underwater is often with pillow structure. The pore structure and amygdaloidal structure may be found in various basalts. The degree of crystallization and grain size of basalt depends mainly on the cooling rate of the magma. If the cooling is slow, for example, a few degrees down a day, the crystals formed are a few millimeters in size and equal in size
Anhui Mingguang City, basalt mineral resources are abundant, a large number of distribution is located in the west of Mingguang City, west of the city street office, 307, 309 provincial highway, 104 national highway, Bengning Expressway, Jinghu Railway through the territory, West Xu Industrial Zone sand and gravel special dock can dock 500 tons of ships direct navigation Yangtze River, the location is superior, the traffic is very convenient. Now the proven prospective reserves of 168 million tons, the proven exploitable reserves of 34 million tons, the largest reserves in the eastern part of Anhui, the annual mining and processing volume in more than 1 million tons, by Southeast University, Tongji University science and technology testing for the national level basalt. Basalt is the main raw material for the production of cast stone. With high chemical and acid resistance, hardness and mechanical strength, basalt is widely used in chemical, metallurgical, electric power, coal, building materials, textile and light industrial sectors. Basalt is the raw material for the production of basalt paper, lime volcanic rock clinker-free cement, decorative plates, artificial fibers, and is also an energy-saving raw material in the ceramic industry.
Basalt fiber, is a continuous fiber made of basalt stone molten at 1450℃~1500℃ and drawn at high speed by platinum-rhodium alloy drawing funnel, the strength is comparable to high strength S glass fiber. The color of pure natural basalt fiber is generally brown, some look like gold. Basalt fiber is a new type of inorganic environmental protection green high-performance fiber material, it is composed of silica, alumina, calcium oxide, magnesium oxide, iron oxide and titanium dioxide and other oxides of basalt stone in the high temperature melt, through the funnel plate quickly drawn from. Basalt continuous fiber not only has high strength, but also has many excellent properties such as electrical insulation, corrosion resistance and high temperature resistance. In addition, the production process of basalt fiber decides to produce less waste, less pollution to the environment, and the product can be directly degraded in the environment after disposal, without any harm, so it is a veritable green, environmentally friendly materials. China has listed basalt fiber as one of the four major fibers (carbon fiber, aramid, ultra-high molecular weight polyethylene, basalt fiber) to be developed and industrialized. Basalt continuous fiber has been widely used in many fields such as fiber-reinforced composites, friction materials, shipbuilding materials, heat insulation materials, automotive industry, high-temperature filter fabrics and protective fields.
Basalt fiber as the filter material of dry filtration device, basalt high temperature resistant dust bag is mainly used for industrial dust removal and smoke and gas purification. Due to the excellent properties of basalt fiber itself such as high strength, high temperature resistance, corrosion resistance and low elongation, the filter bags made of basalt high temperature resistant dust bag have the following characteristics.
