摘　　要：气凝胶玻璃是新型建筑围护结构优质产品,能有效降低能耗损失,目前国内外以颗粒气凝胶玻璃为主。本试验选择6种不同粒径范围气凝胶颗粒(6~8目、8~10目、10~12目、12~14目、14~16目、16~18目)及4种不同填充厚度中空玻璃(5.5mm、6mm、8mm、10mm)进行复合,研究两种因素对透光效果及隔热效果的影响。结果表明,在相同填充厚度下,气凝胶玻璃填充颗粒粒径在8~16目时,随着颗粒粒径减小,透光率逐渐降低,而当粒径在16~18目时,可见光透射率反而提升。填充颗粒粒径相同时,填充厚度越小,可见光透射率越高。将气凝胶玻璃与传统中空玻璃对比,透光率有所降低的同时,传热系数大幅降低,在100℃光线照射下,气凝胶玻璃隔热效果随着颗粒粒径减小逐渐提升,随着填充厚度增加逐渐提升,且远高于普通中空玻璃,进一步确认了其优异的节能效果。Aerogel glass is a high quality product of new building envelope structure, and it can effectively reduce the loss of energy consumption. At present, granular aerogel glass is the main product at home and abroad. In this paper, six kinds of aerogel particles with different particle sizes(6~8 mesh, 8~10 mesh, 10~12 mesh, 12~14 mesh, 14~16 mesh,16~18 mesh) and four kinds of insulating glass with different filling thicknesses(5.5mm, 6mm, 8mm, 10mm) are selected for compound. The influence of two factors on light transmittance and thermal insulation is studied. The results show that when the particle size of aerogel glass is 8~16 mesh with the same filling thickness, the light transmittance decreases gradually with the particle size decreasing, and the visible light transmittance increases when the particle size is 16~18mesh. When the filling material is the same, the smaller the filling thickness, the higher the visible light transmittance. By comparing aerogel glass with traditional insulating glass, the light transmittance decreases somewhat and the heat transfer coefficient decreases significantly. Under the light irradiation at 100℃, the thermal insulation effect of aerogel glass gradually increases with the decrease of particle size, and gradually increases with the increase of filling thickness, which is much higher than that of ordinary insulating glass, further confirming its excellent energy-saving effect.
