通过模拟试验及其与参比试样红外光谱图的对比 ,研究了反复使用的铸镁无毒型砂的高温反应。发现长期使用的无毒型砂在高温反应生成高沸点烃和硼砂 (四硼酸钠 )。
Through the simulation test and comparison with the infrared spectrum of the reference sample, the high temperature reaction of the non-toxic cast sand used repeatedly was studied. Long-term use of nontoxic sand was found to react at high temperatures to produce high-boiling hydrocarbons and borax (sodium tetraborate).
