Example Embodiment
[0042] Example 1
[0043] In terms of mass percentage, 60wt% of SiO 2 , 10.8wt% Al 2 O 3 , 22.4wt% CaO, 0.3wt% MgO, 0.3wt% TiO 2 , 4.0wt% Y 2 O 3 , 0.7wt% La 2 O 3 , 0.3wt% CeO 2 , 0.4wt% Li 2 O, 0.7wt% Na 2 O+K 2 O, 0.1wt% Fe 2 O 3 Calculate the required raw material addition ratio according to its formula. According to this ratio, the various raw materials are quantitatively transported to the mixing silo, fully mixed uniformly, and qualified batch materials are obtained; the batch materials are transported to the kiln head silo of the tank kiln. The feeder is delivered to the kiln at a uniform speed; the batch materials are heated, melted, clarified and homogenized in the kiln at a high temperature of 1300-1500 ℃ to form a qualified high-transparency glass 1; the high-transparency glass 1 is cooled to Molding temperature, then flow out through the platinum plate to form high-transparency glass fiber 1; the glass fiber 1 is quickly drawn into a high-transparency glass fiber 1 wi...
