Embodiment 1
[0022] In terms of parts by weight, select 42 parts of quartz sand, 26 parts of wax stone, 13 parts of limestone, 11 parts of dolomite, 9 parts of leucoporite, 4 parts of fluorite, 3.5 parts of Glauber's salt and 2.5 parts of colemanite, and mix well Then put it into the kiln for calcination, the temperature of the glass liquid is controlled at 1460°C, and the glass liquid with uniform composition is melted; then the glass liquid passes through the leak plate to form a glass filament stream; Secondary melting and pulling into ultrafine glass fibers, and then formulating 2% methyl silicone oil, 0.5% ammonium sulfate, 3% KH560 silane coupling agent, 1% SS-200 bonding aid relative to the weight ratio of ultrafine glass fibers Evenly atomize and spray on the surface of ultra-fine alkali-free glass fiber cotton, and evenly disperse on the forming net; finally dry in a drying room at 148°C for 8 minutes;
[0023] After testing, the average fiber diameter of ultra-fine alkali-free gl...
