摘　　要：以粉煤为原料,改性木屑为粘结剂,采用碱液、酵母菌、复合菌为木屑改性剂,冷压成型制备型煤。分别讨论了改性剂、改性粘结剂添加质量分数和腐植酸钠作为复合剂添加质量分数对型煤强度的影响。结果表明:NaOH改性木屑与腐植酸钠作为复合粘结剂制备的型煤抗压强度和跌落强度最好。By using pulverized coal as raw material,modified sawdust as binder,lye,yeast and composite bacteria as sawdust modifier,briquette is prepared through cold forming.The effects of modifier,the adding mass fraction of modified binder and the adding mass fraction of sodium humate as the compounding agent on briquette strength are discussed.The results show that the compressive strength and drop strength of the briquette prepared by NaOH modified sawdust and sodium humate as composite binder is the best.
