【摘要】：為了改善多孔陶瓷的隔熱性能,以工業(yè)硅藻土為原料,Isobam-104為分散劑和結(jié)合劑,羧甲基纖維素鈉為穩(wěn)泡劑,十二烷基硫酸三乙醇胺為發(fā)泡劑,通過發(fā)泡注漿成型工藝制備了硅藻土多孔陶瓷,并研究了燒成溫度(分別為1 100、1 150、1 200和1 250℃)對其性能的影響。結(jié)果表明:隨著燒成溫度的提高,所制備多孔陶瓷的顯氣孔率逐漸降低,耐壓強(qiáng)度逐漸增大;當(dāng)燒成溫度為1 100℃時(shí),多孔陶瓷的顯氣孔率和耐壓強(qiáng)度分別為84.5%和1.11 MPa;當(dāng)燒成溫度增至1 200℃時(shí),試樣的顯氣孔率和耐壓強(qiáng)度分別為83.4%和2.01 MPa,其在200℃下的熱導(dǎo)率為0.105 W·m~(-1)·K~(-1),具有較好的隔熱性能。綜合考慮硅藻土多孔陶瓷的各項(xiàng)性能認(rèn)為,其最佳燒成條件為1 200℃保溫2 h。
