【摘要】：以氧化鋁纖維和玻璃粉為主體材料,活性炭粉為造孔劑,通過半干壓成型工藝制備了高溫煙氣過濾陶瓷。詳細研究了玻璃粉含量、造孔劑含量以及燒成溫度對材料過濾阻力、抗折強度、顯氣孔率等性能的影響,并對原料配方和燒成制度進行了優(yōu)化,最優(yōu)配方為:氧化鋁70wt%、玻璃粉30wt%、外加造孔劑25wt%、羧甲基纖維素鈉8wt%,最佳的燒成溫度為1100℃,制得的高溫煙氣過濾陶瓷抗折強度8.9 MPa,過濾阻力95 Pa,顯氣孔率達59%。
[Abstract]:High temperature flue gas filter ceramics were prepared by semi-dry pressing process with alumina fiber and glass powder as main material and activated carbon powder as pore making agent. The effects of glass powder content, pore-making agent content and sintering temperature on material filtration resistance, flexural strength and apparent porosity were studied in detail, and the raw material formulation and sintering system were optimized. The optimum formula is as follows: alumina 70wt, glass powder 30wtt, external pore-making agent 25wt, carboxymethyl cellulose sodium 8wt, the best sintering temperature is 1100 鈩，
