Abstract

The invention relates to a formulation for producing low-boron glass fiber, in particular to a formulation for producing glass fiber by utilizing quicklime to replace limestone. In the prior glass fiber formulation, the limestone is generally used to introduce CaO, but in the process of melting and decomposing the limestone, a large amount of CO2 is generated for not only increasing the emission of waste gas, but also increasing the energy consumption of a kiln furnace. The invention provides the formulation for producing the low-boron glass fiber, which is characterized in that compositions of main raw materials include quartz sand, quicklime, pyrophyllite, burned dolomite, borocalcite and the like. The low-boron glass fiber produced by the formulation has the advantages of not only improving melting ratio of the kiln furnace, quickening reaction of glass materials, saving energy consumption, achieving the aim of lowering production cost, but also effectively reducing emission amount of waste gas and lowering environmental pollution.

Description

Technical field

[0001] The invention relates to a production formula of low-boron glass fiber, in particular to a production formula of using quicklime instead of limestone to produce glass fiber. Background technique

[0002] E glass is the most commonly used glass component for the production of continuous glass fibers. The components of traditional E glass fiber generally have a relatively high content of CaO, which is mainly derived from boronite and limestone. Due to the high price of boronite, a large amount of boride will be discharged into the atmosphere with waste gas during the production process to pollute the environment. Therefore, the development of low boron E glass fiber is of great significance in terms of raw material cost and environmental protection. In the raw materials of low-boron E glass fiber, the amount of boronite is very small or even zero, which leads to the need to use a large amount of limestone to introduce CaO. During the melting and decomposition...
