First, the selection of raw materials
Basalt is a common volcanic rock that is a potential fibrous raw material due to its high mineral content and fiber morphology. During the production process, basalt of good quality, rich in silicon and magnesium, is selected as the main raw material.
2. Melt spinning
The basalt raw material is treated at high temperatures, melted, and then the melt is ejected through a high-speed nozzle. In the ejection process, the melt is stretched by air flow or mechanical force to form filamentous fibers, which are then cooled and solidified to form basalt fibers.
3. Stretching and processing
Basalt fibers also need to be stretched and processed after melt spinning to guarantee their stability and overall quality. The process of stretching can further improve the structure of the fiber, increasing its strength and toughness. In the process of processing, it needs to be processed by weaving and weaving to improve its efficiency and suitability.
Fourth, the application field and advantages
Basalt fibers have high strength and heat resistance, making them tougher and more durable than other fibers. It is often used in high-temperature, flame retardant and anti-corrosion fields, such as aerospace, chemical industry, new energy, environmental protection, engineering materials, etc. At the same time, basalt fiber also has good environmental protection properties and is a sustainable material.
