“Turning Stone into Gold"-Excellent Properties and Applications of Basalt Fiber

Basalt fiber, this seemingly ordinary material, but hidden “stone into gold” like magic power. As a new type of inorganic environmentally friendly high-performance fiber materials, it is unique and excellent performance in many fields to show a broad application prospects. This paper will be from the preparation of basalt fiber, performance characteristics and application areas of the three aspects, in-depth discussion of its “stone into gold” mystery.

Preparation of basalt fiber
Basalt fiber preparation process mainly includes raw material selection, melting and drawing, fiber molding, post-treatment and quality testing steps. Raw material basalt is a kind of volcanic rock rich in silicon, aluminum, iron, magnesium, calcium, sodium, potassium, titanium and other elements, these elements give the basalt fiber excellent chemical stability and physical properties. In the melting and drawing process, the basalt is melted by high temperature, and then through a special drawing process, the molten basalt is drawn into a continuous fiber. After the post-treatment process, the strength and stability of basalt fibers are further improved, and finally become high-performance fiber materials that can be used in various fields.

Basalt fiber performance characteristics
1. high strength: basalt fiber strength is much higher than ordinary glass fibers and organic fibers, and even comparable to high-performance carbon fiber. This makes the basalt fiber under high load, high pressure and other extreme conditions can still maintain good stability.
2. High temperature resistance: the melting point of basalt fiber is as high as 1500 ℃ or more, and at high temperatures can still maintain high strength and stability. This makes basalt fiber has a wide range of applications in high temperature environment, such as aerospace, automotive engines and other fields.
3. Corrosion resistance: the chemical stability of basalt fiber is excellent, able to resist the erosion of acid, alkali, salt and other chemicals. This makes basalt fiber in the chemical industry, marine engineering and other fields have unique advantages.
4. Environmental protection: basalt fiber raw material basalt is a natural mineral widely available in nature, its mining and use of the process of environmental pollution. At the same time, basalt fiber itself can be recycled, has a high environmental value.

Basalt fiber application fields
1. Construction field: basalt fiber can be used to make high-performance building materials, such as basalt fiber reinforced concrete, basalt fiber reinforced gypsum board and so on. These materials have high strength, high durability, corrosion resistance and other advantages, in bridges, tunnels, high-rise buildings and other projects have a wide range of applications.
2. Aerospace field: the high temperature stability and high strength of basalt fiber make it an important material in aerospace field. It can be used to make aircraft engine parts, heat insulation materials, rocket launchers and other key components.
3. Automotive industry: basalt fiber can be used for automotive lightweight design, such as body structure, engine heat shield, exhaust pipe and other components. Its high strength and high temperature resistance help to improve the safety and durability of automobiles.
4. Environmental protection field: the environmental protection of basalt fiber makes it has a wide range of application prospects in the field of environmental protection. It can be used to make key parts of environmental protection equipment such as sewage treatment equipment, flue gas desulfurization equipment and garbage incinerator.
5. Other fields: basalt fiber can also be used in the production of sporting goods, shipbuilding, cable sheathing and other fields. Its excellent performance makes basalt fiber in these fields also has a wide range of application prospects.
In short, basalt fiber as a new type of inorganic environmentally friendly high-performance fiber materials, its excellent performance characteristics and a wide range of application prospects make it become a hot spot for research in the field of materials science. In the future, with the continuous progress of science and technology and people's awareness of environmental protection continues to improve, basalt fiber will be in more areas to show its “stone into gold” magic power.
