| 摘 要： | 以型煤稳定性为考察指标,研究NaOH与玉米淀粉的反应时间、反应温度、反应物配比及无烟粉煤与黏结剂的比例等因素对型煤稳定性的影响。用改性淀粉黏结剂与无烟粉煤混合,采用单因素实验法优化型煤成型的制备条件。黏结剂的最佳制备条件：反应时间1h,反应温度75℃,淀粉与水的质量比1：14,NaOH与水的质量比1：100,黏结剂占煤球质量的13%。添加了多功能淀粉基黏结剂的型煤的热稳定性较好,采用最佳的制备条件,制得抗压强度为1032.4N的型煤。

| Abstract: | Taking briquette stability as research target,investigate the influence of NaOH and corn starch reaction time,reaction temperature,reaction ratio,ratio of anthracite and binder on briquette stability.Mixing modified starch binder with anthracite,optimize preparation conditions of briquette with single factor experiments.The best binder preparation conditions is that the time is 1 h,heat-treatment temperature is 75 ℃,corn starch and water ratio is 1：14,NaOH and water ratio is 1：100,the binder mass is 13 percent of egg-shaped briquette mass.Under the best preparation condition,the compression resistance can reach 1032.4 Newton. |
