Abstract

The invention discloses a method for producing glass fiber by using spodumene slag as a fluxing clarifier. The method comprises the steps of weighing, blending, melting, penetrating, wire drawing, drying and the like. The glass fiber is prepared from the following components in parts by weight: 100-120 parts of kaolin, 150-410 parts of pyrophyllite, 150-200 parts of quicklime, 50-70 parts of dolomite, 50-70 parts of colemanite, 130-310 parts of white afrodite, 20-30 parts of fluorite and 10-30 parts of spodumene slag, and the sum of the parts by weight of the components is 1000. The spodumeneslag is used as the fluxing clarifier, so that the prepared glass fiber can be prevented from deliquescing and caking; and furthermore, the spodumene slag can reduce the fire resistance of the kaolin,and the melting temperature is not needed for keeping stability, so that the difficulty of industrial production is reduced. By adopting the method provided by the invention for producing the glass fiber, the cost is lowered, the pollution of the slag to the environment can also be reduced, and the method has better 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...
