摘要: 发泡陶瓷作为一种新型建筑墙体材料,具有轻质保温的优良特性,有利于实现建筑节能。以黄姜废渣为主要坯料,掺加适量麻城石粉优化坯料组分,并以SiC为发泡剂,通过混料、压片、烧结等工艺实现了一种新型闭孔发泡陶瓷的制备。主要研究了烧成制度、成型压力、发泡剂掺量、石粉掺量对黄姜废渣发泡陶瓷宏观性能及其微观特征的影响。试验结果表明,在烧成温度1 130 ℃、升温速率5 ℃/min、成型压力1 MPa、SiC掺量0.5%、麻城石粉掺量40%(均为质量分数)的工艺条件下,黄姜废渣发泡陶瓷制备效果最佳,综合性能最优。

Abstract: As a new type of building wall material, foamed ceramics have the excellent characteristics of lightweight and heat preservation, which is conducive to building energy saving. A new type of closed-cell foamed ceramics was prepared by mixing, tableting, sintering and other processes with turmeric slag as the main billet, adding proper amount of Macheng stone powder to optimize the billet composition, and SiC as the foaming agent. The effects of firing system, molding pressure, foaming agent content, and stone powder content on the macroscopic properties and microscopic characterization of turmeric residue foamed ceramics were studied. The test results show that when the firing temperature is 1 130 ℃, the heating rate is 5 ℃/min, the molding pressure is 1 MPa, the SiC content is 0.5%, and the Macheng stone powder content is 40% (both are mass fraction), the turmeric waste slag foamed ceramics has the best preparation effect and the best overall performance.

Key words: turmeric residue, Macheng stone powder, foamed ceramics, SiC, pore structure, thermal insulation material
