摘要
本文讨论了预热温度、含水量、膨胀温度、膨胀时间等因素对珍珠岩膨胀倍数测试结果的影响。试验结果表明,珍珠岩的最佳膨胀条件为:预热温度360～400℃、含水量2%～3%、膨胀温度1 150～1 170℃、膨胀时间10～18s。
This paper discussed influence fators of preheating temperature, water content, expansion temperature and time of perlite expansion test. The result of the best perlite expand condition show that preheat temperature is 360-400℃, the water content is 2%-3%, expansion temperature is 1 150-1 170℃ and expansion time is 10-18s.
