Abstract

The invention discloses a method for producing glass fiber by using spodumene slag as a fluxing and clarifying agent, which comprises the steps of weighing, batching, melting, passing through, wire drawing, drying and the like; the components are weighed according to the following parts by weight: Kaolin: 100-120, pyrophyllite: 150-410, quicklime: 150-200, dolomite: 50-70, colemanite: 50-70, leucolite: 130-310, fluorite: 20-30, lithium 10-30 parts of pyroxene slag, the sum of parts by weight of each component is 1000. The present invention uses spodumene slag as a melting flux clarifying agent, which can prevent deliquescent agglomeration of the prepared glass fiber, and the spodumene slag can reduce the refractoriness of kaolin, and does not need to keep the melting temperature stable, thus reducing industrial production. difficulty. Adopting the method provided by the invention to produce glass fiber not only reduces the cost, but also reduces the environmental pollution caused by slag, and has good economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of glass fiber manufacture, and in particular relates to a method for producing glass fiber by using spodumene slag as a melting flux clarifying agent. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance, which has the advantages of good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. The glass fiber is usually used as reinforcing material, electrical insulation and heat insulation materials in composite materials, and it is widely used in various fields of national economy. [0003] At present, my country's glass fiber industry mainly adopts the pool kiln wire drawing production process. When glass fiber is produced by this process, the main raw material for fluxing and clarifying agent is Glauber's salt. When Glauber's salt is used as a fluxing and clarifying agent, because of its raw material characteristic...
