11.13 Glass Fiber Manufacturing
Glass Fiber General1-4 Glass Fiber Manufacturing is the high-temperature conversion of various raw materials(predominantly borosilicates) into a homogeneous melt, followed by the fabrication of this melt intoglass fibers. The 2 basic types of Glass Fiber products, textile and wool, are manufactured by similarprocesses. A typical diagram of these processes is shown in Figure Glass Fiber productioncan be segmented into 3 phases: raw materials handling, Glass melting and refining, and wool glassfiber forming and finishing, this last phase being slightly different for textile and wool Glass Materials Handling -The primary component of Glass Fiber is sand, but it also includes varying quantities offeldspar, sodium sulfate, anhydrous borax, boric acid, and many other materials.
given in Tables 11.13-1, 11.13-2, and 11.13-3. Raw Materials Handling - The major emissions from the raw materials handling phase are fugitive dust and raw material particles generated at each of the material transfer points. Such a point would be where sand pours from a …
