Section 1:Product Introduction
1Basalt Fiber Introduction
Basalt continuous fiber materials are renowned as“21Century新材料”Using basalt ore as raw material, the ore is crushed and then added to the furnace.1450℃～1500After melting at °C, the uniform molten material is first drawn through a drawing die to form coarse fibers, which are then drawn by a drawing machine into various specifications of continuous fibers. Subsequently, different sizing agents are applied for sizing treatment based on the subsequent use, and the fibers are processed into the final product.
Finished Product.
Compared to other high-performance fibers such as glass fiber, carbon fiber, and aramid, basalt fiber not only boasts excellent mechanical properties but also features numerous superior functionalities, such as excellent high-temperature resistance.-260～700Operates continuously within the °C range; resistant to acids and alkalis, with strong UV resistance, low moisture absorption, and superior environmental endurance; excellent insulation properties, high-temperature filtration, and radiation resistance, etc. Therefore,Basalt fiber is a low-cost substitute for carbon fiber, ranking as the fourth-largest high-tech fiber after carbon fiber, aramid, and ultra-high molecular weight polyethylene fiber.
（1Excellent mechanical properties：
The tensile strength of basalt fiber is3000～4900Mpa, larger tow carbon fiber, aramidPBIFibers, steel fibers, boron fibers, and alumina fibers all require high quality.SGlass fiber is comparable. However, its tensile elongation at break is greater than that of carbon fiber, and the finished product's impact resistance is superior to carbon fiber.Comparison of Mechanical Properties of Various Fiber Materials
