摘要
文章介绍了集保温、隔声与装饰功能于一体的新型模块化保温墙板,该模块化墙板由竹木纤维集成墙板、真空绝热板与气凝胶毡组成,并对其开展了热工与隔声性能试验研究,结果表明:该墙板的传热系数K为0.36 W/(m2·K),计权隔声量RW为35 dB。在研究的基础上,将保温材料进行适当替换,用于既有公共建筑围护结构节能改造中,应用结果表明:改造后的墙体保温隔热性能提升较为明显。
A new type of modular thermal insulation wallpanel with thermal insulation,sound insulation and decoration functions has been developed.The modular wallpanel is made up of bamboo wood fiber integrated wall panels,vacuum insulation panels and aerogel felt.Thermal and sound insulation performance were tested.The results showed that the heat transfer coefficient of the wallboard Kis 0.36 W/(m2·K)and the weighted sound insulation RWis35dB,Based on this study,appropriate replacement of insulation materials was used to improve the comprehensive performance of the existing public building.The application results indicated that thermal insulation performance of the retrofitted wall is significantly improved.
