疏水性型煤粘结剂的制备及应用

Preparation and Application of a Hydrophobic Cohesive Agent for Briquette

以食醋酿造厂的废渣醋糟和石墨生产中的碱性废液为原料，制备疏水性型煤粘结剂。通过正交试验确定了粘结剂的最佳制备条件。制得的粘结剂有强的粘结性，与煤粉混合经辊压制成的型煤耐水性好，跌落强度和抗压强度均达到国家工业型煤攻关指标。

A hydrophobic cohesive agent with strong cohesiveness for briquette has been prepared from vinegar lees discharged in the production of edible vinegar and alkaline waste liquor discharged in the production of graphite.The optimum conditions for the preparation of the cohesive agent were determined through orthogonal tests.The briquette made by rolling coal powder mixed with the cohesive agent has good resistance to water and,its resistances to pressure and falling can meet national standerds for industrial briquette.
