有关资料表明,我国年产特种耐火砖(镁碳砖和铝碳砖)8万多t,粘结剂用量按5％计算,则需要4000t左右,而目前产量还不足2500t。由于产不足需,用户不得不使用昂贵的酚醛树脂,这就大大增加了耐火砖的成本。因此,开发生产耐火砖粘结剂大有可为。 据有关部门预测,今后三五年内全国每年 Relevant information shows that China produces more than 80,000 t of special refractory bricks (magnesia carbon bricks and aluminum carbon bricks) per year, and the amount of binder used is calculated at 5%, which requires about 4000 tons, and the current output is less than 2500 tons. Due to insufficient production, users have to use expensive phenolic resins, which greatly increase the cost of firebricks. Therefore, it is very promising to develop and produce refractory bricks. According to the prediction of the relevant department, the national annual amount in the next three to five years
