Investigating the Effect of Drawing Process Parameters on Borosilicate Glass Fiber Thickness

Abstract

Borosilicate glasses have many usage areas due to high thermal and chemical resistance with a very low thermal expansion coefficient. The number of waste borosilicate glasses is increasing in direct proportion to their usage areas. Creating new usage areas by recycling these glasses will provide cost savings. In this paper, the fiber drawing method is used to recycle borosilicate glass. The aim of this article is to investigate the effect of winding speed and temperature of drawing process on fiber thickness. The fiber drawing process was performed at specific temperatures (1100 °C, 1200 °C, and 1300 °C) and at specific winding speeds (50 rpm, 175 rpm, and 300 rpm). In this context, the thermal behavior of borosilicate glasses was determined by DSC and TGA analysis. The structural, elemental, and chemical corrosion resistance properties of borosilicate glass fibers were examined by SEM, XPS, and corrosion test, respectively. The results show that the fiber thickness increased with the increase in the amount of material fed in the crucible, while it decreased with the increase of fiber drawing speed and time.
