Problems solved by technology

[0003] However, because basalt is formed from lava on the earth, its inherent deficiency is the fluctuation of its composition. Not only the composition of different deposits fluctuates greatly, but also the chemical composition of the same deposit has a certain fluctuation range; therefore, although the basalt on the earth is distributed Especially extensive, but there are no

Abstract

The invention discloses a basalt fiber preparation method, a mineral mixture and a production technology. The preparation method comprises the step of grinding the mineral mixture into 200 to 300-meshpowder to obtain basalt fibers. The mineral mixture is prepared from the ingredients in weight percentage: 47% to 59% of SiO2, 11% to 16% of Al2O3, 5% to 9% of CaO, 2% to 7% of MgO, 2% to 5% of Na2O,0.5 to 3% of K2O, 0 to 2.6% of Li2O, 7% to 16% of Fe2O3, 1% to 3.4% of TiO2, 0 to 3% of ZrO2, 0 to 2% of CeO2 and 0 to 2% of MnO. The used mineral mixture is prepared from varieties of ores, so thatthe whole ingredient fluctuation range is reduced to the lowest, wiredrawing performance is improved, mineral mixture ingredient contents and mutual proportional relation are controlled, strength is improved, stability is improved, elasticity modulus is improved, a melting temperature is reduced, energy is saved, glass material characteristics are changed, and improving wiredrawing performance isachieved.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a batching method of basalt fiber, a mineral mixture and a production process. Background technique [0002] Basalt fiber is made of natural basalt as raw material. After melting at a high temperature of about 1500 ℃, it is formed by a platinum-rhodium alloy bushing plate, and is continuously drawn by a wire drawing machine for tens of thousands of meters at high speed. Continuous basalt fiber is a new type of environmentally friendly inorganic fiber material, which has excellent properties such as light weight, high strength, high temperature resistance, corrosion resistance, oxidation resistance, radiation protection, heat insulation and sound insulation. It is another high-tech fiber after carbon fiber, aramid fiber and ultra-high molecular weight polyethylene fiber. It has a wide range of uses in aerospace, automobile and ship, civil engineering transportation, energy and e...
