【摘要】：為開發(fā)建筑用泡沫陶瓷保溫材料,基于超輕質(zhì)泡沫地質(zhì)聚合物的制備工藝,探索了高溫?zé)Y(jié)制備地質(zhì)聚合物基泡沫陶瓷材料的工藝途徑,研究了泡沫地質(zhì)聚合物坯體的干燥和燒成制度對泡沫陶瓷性能的影響。結(jié)果表明,采用3 d室內(nèi)自然干燥,5℃/h的速度升溫到105℃并保溫24 h的干燥制度,可避免泡沫地質(zhì)聚合物坯體在干燥過程中的開裂;試樣燒結(jié)過程中,600℃后以60℃/h的升溫速度緩慢升溫到1000℃并保溫2 h,可避免制品開裂。所制泡沫陶瓷干密度262 kg/m3、抗壓強度2.34 MPa、導(dǎo)熱系數(shù)0.099W/(m·K),符合JG/T 042—2013要求。
[Abstract]:In order to develop the thermal insulation material of building foam ceramics, based on the preparation technology of super light foamed geopolymers, the process of preparing geopolymer-based foam ceramic materials by high temperature sintering was explored. The effects of drying and sintering systems of geopolymer foam billet on the properties of foam ceramics were studied. The results show that the cracking of foam geopolymers can be avoided by using the drying system of natural drying for 3 days, heating up to 105 鈩，
