摘　　要：利用混酸消解法测试玻璃原料的COD,利用红外光谱测定玻璃熔体的含水量,利用拉筒法测定玻璃熔体表面张力,研究了原料对玻璃熔制工艺的影响。研究表明:原料的波动直接影响玻璃配合料的Redox和玻璃熔体的澄清效果。稳定矿物原料质量,特别是控制硅砂和白云石的COD值,对稳定玻璃配合料的Redox至关重要。在矿物原料质量稳定的情况下,芒硝含率3.5%时,碳粉含率5%玻璃熔体澄清效果较碳粉含率3%的要好。To investigate the effects of raw materials for the melting process of glass, mixed acid digestion method was used to determination COD of the glass materials, infrared spectroscopy was used to test water content of glass melt and Czochralski method was used to test surface tension of glass melt. Results show that the volatility of raw ma- terials directly affect glass batch redox and fining effect of glass melt. Keeping the quality of mineral raw materials sta- ble, especially controlling the COD of silica sand and dolomite attaches great importance to redox of glass batch. With a consistent qtiality of mineral raw materials, when the rate of salt cake remains 3. 5 %, the glass melt with 5 % carbon implies a better fining effect than that of glass melt with 3% carbon contenting.
