摘　　要：采用工业固体垃圾——煤矸石为生产原料制备白炭黑,通过改变制备过程中的通气速度、CO2质量分数及后处理工艺,研究工艺参数对白炭黑脱水性能的影响。结果表明,在制备白炭黑过程中,可以通过改变制备工艺条件来控制白炭黑的粒度,以致生成粒度较大、形态为絮状的白炭黑沉淀。同时,在洗涤中也应适当搅拌,从而提高其脱水性能。这样,既可以节约成本,也可以提高产品的纯度。Amorphous white carbon black is prepared with industrial solid waste-coal gangue as raw material.The effect of different preparation conditions,such as ventilation rate、CO2concentration and post-processing technique in the process of preparation on the dehydration property of white carbon black are investigated.Results show that the size of white carbon black can be controlled by varying preparation condition parameters,so that the larger and flocculent white carbon black precipitations are generated.Meanwhile,proper stirring should also be executed in the washing to improve the dehydration performance.It not only can save costs,but also improve the purity of the product.
