- AR- A manufacturing method for AR-glass fibers using the coal Waste and manufacturing for AR-glass fibers

摘要

The present invention relates to a method for producing AR-glass fiber using coal waste seals and AR-glass fiber produced thereby, comprising the steps of: 1) mixing raw glass fiber materials having an AR glass composition with stirring; 2) melting the mixed raw material of the AR glass composition at a high temperature to form a molten glass; And 3) fiberizing the molten glass of the AR glass composition into AR-glass by using a fibrousizing apparatus. By using silica-alumina sandstone coal waste having a relatively small carbon content, It is possible to manufacture bulk glass and fiber glass of each of the produced AR (Alkali Resistant) glass compositions, thereby making it possible to use it as a concrete reinforcing material or the like.
