改良型实木复合门的隔声与保温性能

Sound and Thermal Insulation Performance of Modified Solid Wood Composite Doors

为了提高实木复合门的隔声、保温性能,对普通意杨LVL实木复合门扇进行结构改良设计,用现场声压级测量法和热流计测量法,分别检测实木复合门的隔声量和传热系数值。结果表明,改良后实木复合门的隔声量比普通复合门提高1.2倍,传热系数K值远低于普通实木复合门,传热等级达到10级。

In order to improve sound and thermal characteristics of solid wood composite doors,the authors developed an optimization structural design for the door leaves.The modified wood composite door leaf was made of laminated veneer lumber(LVL)as the frame and with high density fiberboard(HDF)as the face layer of door sheets to replace MDF,and with glass fiber as the filler to replace honeycomb paper.Live sound pressure level measurement and heat flow metering methods were used to measure sound insulation and heat transfer coefficient values,respectively.The results showed that compared with control composite doors,the sound insulation of the modified door increased by 1.2 times with much lower heat transfer coefficient value,which reached the highest level.
