Definitions
- delta T is a common measure of the crystallization potential of a given melt composition.
- ⁇ T is typically maintained at a temperature of at least 90°F (50°C) in order to prevent devitrification of the molten glass in the bushing area of a glass fiber forming operation.
- Boron and fluorine containing glass were developed to meet these operating conditions. More specifically, the boron and fluorine were included in the glass batch materials to act as fluxes during the glass melting operation. However, these materials are volatilized during melting and boron and fluorine emissions are released to the atmosphere.
- U.S. Patent No. 4,542,106 discloses a boron-free and fluorine-free glass composition that contains 1 to 5 percent by weight TiO 2 .
- the fibers also have a seed count of 5 seeds or less per cubic centimeter of glass and an electrical leakage value of 2.8 nanoamperes or less.
- the base composition for the glass fibers of the present invention suitable for textiles and glass fiber reinforcements includes the following main constituents in weight percent (wt%) based on the total weight of the final glass composition. broad range preferred range most preferred range
- glass fibers of the present invention can be prepared in the conventional manner well known in the art, by blending the raw materials used to supply the specific oxides that form the composition of the fibers. For example, typically sand is used for SiO 2 , clay for AI 2 O 3 , lime or limestone for CaO, and dolomite for MgO and some of the CaO. As discussed earlier, the glass can include other additives that are added to modify the glass properties as well as small amounts of melting and refining aids, tramp materials or impurities.
- Table 9 includes several glass fiber melt compositions made in a commercial glass melting operation. The amount of each constituent in the table is the weight percent in the actual melt. The weight percent for the Li 2 0 was determined using wet chemical analysis techniques, the weight percent for the B 2 O 3 was determined using Neutron Transmission analysis techniques, and the weight percent for the remaining constituents was determined using X-ray fluorescence analysis (also referred to as "XRF analysis”), all of which are well know to those skilled in the art.
- XRF analysis also referred to as "XRF analysis”
