Embodiment Construction
[0012] The invention adopts powder melting method to prepare foam glass, and provides a novel electrodeless structure material with good acid corrosion resistance through formula design. In order to obtain higher acid corrosion resistance and thermal shock resistance, borosilicate glass is selected as the basic glass, and a foaming agent is added to the basic ingredients for preparing borosilicate glass. When the batch is heated to melt and soften, the viscosity When it is lowered, the blowing agent just starts to react and generate gas, and the gas is enclosed in the glass liquid in an elastic state. As the temperature rises, the viscosity of the glass gradually decreases, and the gas expands and the bubbles increase. When the bubbles increase to a certain extent, the temperature drops rapidly, the viscosity of the glass increases sharply, and the bubbles are finally settled.
[0013] The foaming agent is 0.5% to 0.8% of the total mass of the basic batch. The foaming agent ca...
