Embodiment 1
[0021] A method for preparing foamed glass with a high foaming rate by using lead-free high-barium waste lamp tubes. The preparation method is to use lead-free high-barium waste lamp tubes to form raw material glass powder through ball milling, and mix foaming agents such as manganese dioxide, calcium carbonate, and auxiliary The flux sodium fluorosilicate and the stabilizer sodium phosphate are fed into the ball mill for ball milling, and the mixture after ball milling is fed into the high temperature resistant mold for preheating at 400~430°C for 15~20 minutes, and then the temperature is raised to 800~820°C for Foaming, foaming time 20~30min, then cooling to 500~550℃ for annealing, annealing time 35~40min, and finally cooling to room temperature with the furnace.
[0022] Among them, manganese dioxide, calcium carbonate, sodium fluorosilicate and sodium phosphate account for 3%~6%, 4%~8%, 4%~6%, 7%~9% of the total weight of the glass powder respectively; The particle size o...
Embodiment 2
[0029] 100 parts by weight of glass powder, 3 parts by weight of manganese dioxide, 6 parts by weight of calcium carbonate, 5 parts by weight of sodium fluorosilicate, and 9 parts by weight of sodium phosphate are sent into the ball mill for ball milling, and the particle size is 160 mesh; For the mold, the preheating temperature is 420°C for 17 minutes, the foaming temperature is 800°C for 20 minutes, and the annealing temperature is 530°C for 35 minutes. The prepared foam glass as figure 1 As shown, the pore diameter is relatively uniform, the average pore diameter is 2.8mm, the apparent density is 0.71g / cm3, and the compressive strength is 5.24MPa.
Embodiment 3
[0031] 100 parts by weight of glass powder, 4 parts by weight of manganese dioxide, 5 parts by weight of calcium carbonate, 4 parts by weight of sodium fluorosilicate, and 7 parts by weight of sodium phosphate are sent into the ball mill for ball milling, and the particle size is 175 mesh; For the mold, the preheating temperature is 420°C for 17 minutes, the foaming temperature is 810°C for 25 minutes, and the annealing temperature is 530°C for 35 minutes. The prepared foam glass as figure 2 As shown, the pore diameter is relatively uniform, the average pore diameter is 3.6mm, the apparent density is 0.64g / cm3, and the compressive strength is 4.53MPa.
