摘 要 以廢瓷粉、廣西白泥、碳化硅、硅微粉為主要原料,鋁酸鈣水泥為結(jié)合劑, 加適量水配置成耐堿澆注料。通過調(diào)整碳化硅的加入量,研究碳化硅對耐堿澆注料性能影響, 以及澆注料的耐堿侵蝕機(jī)理。結(jié)果表明:隨碳化硅加入量的增加,試樣體積密度呈現(xiàn)先增加后降低的趨勢,耐壓強(qiáng)度和抗折強(qiáng)度都有不同程度的降低,當(dāng)燒結(jié)完全后,強(qiáng)度又呈增加趨勢。在加熱過程中,碳化硅氧化成一層致密的氧化膜,其阻止了堿蒸汽的侵蝕。當(dāng)碳化硅添加6~8%時,試樣的耐堿等級達(dá)到一級,耐堿侵蝕能力明顯增加。 Abstract: Alkali resistant castable , which was configured by the waste porcelain powder,Guangxi white mud,silicon carbide and silicon powder as main raw materials,calcium aluminate cement as binder and appropriate amount of water.then by adjusting the amount of silicon carbide to study the impact of alkali resistant castable and the erosion mechanismon of alkali resistant castable by silicon carbide. The results showed that with the increasing of silicon carbide , volume of sample density increased first and then decreased, the compressive strength and bending strength were reduced in different degree, when sintering was completed,the Strength showed an increasing trend. The silicon carbide form a layer of compact smooth film gradually in the heating process of oxidation , which prevented alkali vapor erosion. when the silicon carbide added 6 ~8%, samplelevel reached the level of alkali, alkaline erosion ability increased significantly. |
