Method for preparing sintering material from secondary aluminum ash
The invention relates to a method for preparing a sintering material from secondary aluminum ash, and belongs to the field of aluminum industry and building materials. The sintering material is mainly prepared from the following raw materials in parts by weight: 10-80 parts of secondary aluminum ash and 20-90 parts of a raw material A. The preparation method comprises the following steps: grinding the raw materials into specific particle sizes, mixing the raw materials, carrying out semi-dry pressing to obtain a green body, drying the green body, heating the green body to 850-1050 DEG C, carrying out heat preservation for a certain time, and carrying out in-furnace cooling to obtain the sintered material. According to the invention, the harmful components in the secondary aluminum ash are effectively cured, a new treatment direction is provided for the secondary aluminum ash, the obtained sintered material is excellent in performance and wide in application range, and all the performance can meet the corresponding national standard.
本发明涉及一种利用二次铝灰制备烧结材料的方法，属于铝工业和建筑材料领域。本发明的烧结材料，主要由以下重量份数的原料制成：二次铝灰10~80份，A原料20~90份。本发明将各原料磨细至特定粒度后混料，经半干压成型制成坯体，坯体经干燥后加热至850~1050oC并予以一定时间的保温，随炉冷却后即得烧结材料。本发明有效固化二次铝灰中的有害成分，给其提供一种新的处理方向，所得烧结材料性能优异、应用范围广泛，各项性能均能满足相应国家标准。
