摘要
目的为了解决辽宁省硼工业废弃硼泥污染环境、浪费资源问题,研制新型建材使硼泥得到有效利用.方法以硼泥、粉煤灰、铁尾矿为原料,利用工业马弗炉采用正交实验的方法研究硼泥基烧结砖的烧结工艺参数.结果得到原料的最佳质量配比为4:2:4;最佳工艺为塑性成型压力20 MPa、最高烧成温度1 100℃.对烧结砖试样的测试结果表明本工艺烧结砖的强度高于MU15的普通黏土砖;保温性能优于普通黏土砖.结论烧结工艺使硼泥掺入量提高到了40%,为硼泥的大量利用、解决环境问题开辟了一条新的途径.
A lot of boron sediments have been generated Province. For preventing pollution and resource waste, a kind in the boron producing process in Liaoning of fired brick was developed by utilizing boron sediment, fly ash and iron gangue. The best compound ratio of the above raw materials is 4：2：4, when pressure resistance was regarded as a target. And the best making craft is： 20MPa for moulding, 1 100℃ for highest firing. The test results show that the physical properties of the brick are better than those of daily clay brick MU15. Its heat exchange coefficient is about half of the common clay brick, and the heat preservation property is superior to the common clay brick.
