Embodiment 1
[0029] Follow these steps:
[0030] Step 1: Carry out iron removal and other treatments on the silicon micropowder collected by the dust collection device to remove impurities, and the fly ash must be sieved with 200 mesh;
[0031] Step 2: The raw material formula is calculated by weight percentage, with 80% silicon micropowder, 2% foaming agent, 1% stabilizer, 1% cosolvent, and the rest is fly ash, and the above raw materials are fully mixed and stirred evenly to prepare Obtain mixture, foaming agent is calcium carbonate, silicon carbide and carbonates, stabilizer is boric acid, sodium carbonate and sodium sulfate, cosolvent is sodium carbonate, sodium fluorosilicate and borax;
[0032] Step 3: Put the mixture on the heat-resistant steel dense mesh belt that has been painted with release agent, put it into the furnace and preheat it: put the mixture on the heat-resistant steel dense mesh belt, and the mesh belt runs continuously into the Furnace, the mixture is preheated at ...

[0037] Step 2: The raw material formula is calculated by weight percentage, with 90% silicon micropowder, 4% foaming agent, 3% stabilizer, 2% cosolvent, and the rest is fly ash, and the above raw materials are fully mixed and stirred evenly to prepare Obtain mixture, foaming agent is calcium carbonate, silicon carbide and carbonates, stabilizer is boric acid, sodium carbonate and sodium sulfate, cosolvent is sodium carbonate, sodium fluorosilicate and borax;
[0038] Step 3: Put the mixture on the heat-resistant steel dense mesh belt that has been painted with release agent, put it into the furnace and preheat it: put the mixture on the heat-resistant steel dense mesh belt, and the mesh belt runs continuously into the Furnace, the mixture is preheated at ...
Embodiment 3
[0041] Follow these steps:
[0042] Step 1: Carry out iron removal and other treatments on the silicon micropowder collected by the dust collection device to remove impurities, and the fly ash must be sieved with 200 mesh;
[0043] Step 2: The raw material formula is calculated by weight percentage, with 85% silicon micropowder, 3% foaming agent, 2% stabilizer, 1.5% cosolvent, and the rest is fly ash, and the above raw materials are fully mixed and stirred evenly to prepare Obtain mixture, foaming agent is calcium carbonate, silicon carbide and carbonates, stabilizer is boric acid, sodium carbonate and sodium sulfate, cosolvent is sodium carbonate, sodium fluorosilicate and borax;
[0044] Step 3: Put the mixture on the heat-resistant steel dense mesh belt that has been painted with release agent, put it into the furnace and preheat it: put the mixture on the heat-resistant steel dense mesh belt, and the mesh belt runs continuously into the Furnace, the mixture is preheated a...
