Investigation of Certain Flaws Appearing in Glass Melt During the Production of Continuous Glass Fiber

It was established by means of morphological and electron-probe analysis that one of the flaws appearing in glass melt during the production of glass fiber that increases breakage are inclusions of molybdenum disulfide, which forms as a result of corrosion of the electrodes. The source of the flaws could also be salt deposits, condensing on the sub-draw-plate coolers and consisting predominately of sodium chloride, sodium sulfofluoride, and the products of corrosion of the coolers, viz. nickel and copper compounds.
