High-strength high-purity basalt continuous fiber production technique

Abstract

The invention discloses a high-strength high-purity basalt continuous fiber production technique which comprises the main procedures of selection, quarrying, crushing, screening, cleaning, picking, charging, founding by heating up, filament cooling, bushing, drawing, conserving by atomizing, infiltration, clustering, winding, yarn driving, detwisting and finished product inspection. During selection, natural basalt is used as a single component raw material, and natural basalt with uniform crystalline structure and high purity is selected. The basic oxide acidity modulus: MK= (SiO2+Al2O3) / (CaO+MgO), the basic oxide acidity modulus is maintained within the range of 4.3-5.8, and meanwhile, Fe2O3+FeO is controlled between 8-15%. The average fracture strength of the produced continuous fiber base yarn can be stabilized within 0.6-0.7 N / tex and is 50-75% higher than 0.4 N / tex specified by national standards, and the filamentation rate is increased by 10%. The technique has easiness and convenience for operation, stable production and low cost, the technical process is friendly to environment and free of pollution, and the product quality is obvious improved.

Description

technical field [0001] The invention relates to a production process of inorganic non-metallic fiber, in particular to a production process of high-performance new high-strength pure basalt continuous fiber. Background technique [0002] Continuous basalt fibers are lightweight and high-strength, and have excellent properties such as high temperature resistance, oxidation resistance, radiation protection, heat insulation, insulation, and sound insulation. It can be widely used in fire protection, environmental protection, aviation, aerospace, military industry, automobile, shipbuilding, transportation, electrical and electronic, equipment protection, public facilities, chemical construction and other fields. At the same time, it has no harmful gas and waste water discharge in the production process , does not produce waste residue, is a non-polluting and non-carcinogenic green material. Basalt continuous fiber is a fiber material made of natural basalt. However, due to the ...
