Embodiment 1
[0045] Prepare the required raw materials and prepare the ingredients according to the following parts by weight: 23 parts of basalt, 6.5 parts of boronite, 36 parts of pyrophyllite, 14 parts of quicklime, 14 parts of quartz powder, 4 parts of ferric oxide, and 2.5 parts of titanium dioxide. The raw materials are mixed into a batch, and mixed 18 times in a mixing tank with a pressure of 300kPa to obtain a uniform batch. The uniform batch is sent to a 1320°C pool kiln through a kiln head silo and a screw feeder for melting, clarification and homogenization to obtain a black The molten glass, and then the molten glass flows out and enters the main passage at 1270°C, the distribution passage at 1210°C, the working passage at 1150°C, and then enters the platinum-rhodium alloy leakage plate with a leak nozzle at the bottom through the flow tank. The diameter of the molten glass is 1.5- The 2mm nozzle flows out to obtain liquid black glass filaments. The length of the liquid glass fi...
