One,Product Introduction
1Basalt Fiber Introduction
Basalt continuous fiber material is hailed as“21Century's new materials”Processed from basalt ore, the ore is crushed and then added to the furnace.1450℃～1500After melting at ℃, the uniform molten material is first drawn into coarse fibers through a drawing die, then the coarse fibers are drawn into various specifications of continuous fibers by the drawing machine, and different sizing agents are used for sizing treatment according to subsequent applications, to process and form the zui
Final 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 superior high-temperature resistance.-260～700Operates continuously within the °C range; exhibits strong resistance to acids and alkalis, excellent UV resistance, low moisture absorption, and superior environmental durability; good insulation properties, excellent high-temperature filtration, and radiation resistance, etc. Therefore,Basalt fiber is an affordable substitute for carbon fiber and ranks as the fourth largest high-tech fiber, following carbon fiber, aramid, and ultra-high molecular weight polyethylene fiber.
（1Excellent mechanical properties：
The tensile strength of basalt fiber is3000～4900Mpa, compared to large tow carbon fiber, aramidPBIFibers, steel fibers, boron fibers, and alumina fibers all require high quality.SGlass fiber is comparable. However, the elongation at break is greater than that of carbon fiber, and the finished product's impact resistance will be superior to that of carbon fiber.Comparison of Mechanical Properties of Various Fiber Materials
