Heat-preservation sintered brick prepared from municipal sludge and production process of heat-preservation sintered brick
The invention provides a heat-preservation sintered brick prepared from municipal sludge and a production process of the heat-preservation sintered brick, and relates to the technical field of building materials. The production process of the heat-preservation sintered brick by using the municipal sludge comprises the following steps: S1, sequentially carrying out phosphate treatment and ion exchange resin adsorption on the municipal sludge to remove heavy metal ions in the sludge, and then drying the sludge; s2, the sludge and the raw material components are put into stirring equipment to be mixed; s3, the mixed raw materials are compacted and formed in a mold; s4, performing high-temperature firing on the formed green brick; and S5, coating the surface of the sintered brick with a siloxane coating. By reducing the proportion of the expanded perlite micro powder in the raw materials, pores generated in the sintering process are reduced, and the mode of first compacting and then high-pressure pressing in the compaction forming process is adopted, so that the pores in the brick body are more effectively reduced, the density of the brick body is increased, and the bearing strength of the formed sintered brick is further improved.
本发明提供一种利用城市污泥的保温烧结砖及其生产工艺，涉及建筑材料技术领域。该利用城市污泥的保温烧结砖的生产工艺，包括以下步骤：S1对城市污泥依次进行磷酸盐处理和离子交换树脂吸附，以去除污泥中的重金属离子，随后将污泥烘干；S2将污泥与原料组分投入搅拌设备中混合；S3将混合后的原料在模具内压实成型；S4对成型后的砖坯进行高温烧制；S5将硅氧烷涂料涂抹在烧结砖表面。通过在原料中降低膨胀珍珠岩微粉的占比减少烧结过程中产生的孔隙，并且在压实成型时先振实再高压压制的方式，更有效地减少砖体内部的孔隙，增加砖体的密度，进一步的提高成型烧结砖的承载强度。
