Basalt fiber is a fibrous material made from basalt rock with special treatment. It has high strength, fire resistance and corrosion resistance and is widely used in construction, aerospace and automobile manufacturing. In order to ensure the quality and safety of basalt fibers, a series of standards for basalt fibers have been developed.
1. Criteria for physical properties of basalt fibers
The physical property standard of basalt fiber is one of the important indexes to measure its quality. It mainly includes fiber diameter, fiber length, fiber density, tensile strength, elongation at break and so on. Fiber diameter affects the flexibility and strength of the fiber, fiber length directly affects its application range and processing performance. Fiber density affects the thermal conductivity and fire resistance of the material. Tensile strength and elongation at break reflect the tensile and ductile properties of the fiber.
2. Chemical property criteria for basalt fibers
The chemical property standard of basalt fiber is an important basis to ensure its corrosion resistance and environmental friendliness. Mainly includes fiber chemical composition, fiber impurity content, fiber solubility, fiber toughness. Fiber chemical composition directly determines its acid and alkali corrosion resistance and thermal stability Impurity content in the fiber has an important impact on the mechanical properties and processing performance of the fiber. Fiber solubility is an important indicator to assess the stability and solubility of the fiber. Fiber toughness reflects the fracture characteristics and durability of the fiber.
3. Criteria for thermal properties of basalt fibers
The thermal property criteria of basalt fibers are an important basis for assessing their refractory and thermal conductivity properties.
It mainly includes fiber high temperature resistance performance, fiber thermal conductivity, fiber thermal expansion coefficient and so on. The fiber high temperature resistance performance determines its stability and safety in high temperature environment. Fiber thermal conductivity directly affects the material’s thermal insulation performance and heat preservation performance. The fiber thermal expansion coefficient, on the other hand, has an important impact on the thermal and dimensional stability of the fiber.
4. Environmental performance criteria for basalt fibers
The environmental performance criteria of basalt fibers are an important reference for assessing their impact on human health and the environment. Mainly includes the content of harmful substances in the fiber, fiber release degree, fiber bio-persistence and so on. The content of hazardous substances in fibers has an important impact on the harmlessness and environmental friendliness of fibers. Fiber release degree is an important indicator to assess the degree of release and diffusion of fibers. Fiber bio-persistence reflects the decomposition and degradation speed of fibers in the natural environment.
The formulation and implementation of basalt fiber standards are of great significance to ensure the quality and safety of basalt fiber products. Only in strict accordance with the standard requirements for production and testing, in order to ensure the application of basalt fiber in various fields of effect and reliability. At the same time, strengthen the basalt fiber standard research and update, will help to continuously improve the performance and application of basalt fiber, promote the development and progress of related industries.
