塑像表面降尘对塑像地仗吸湿脱湿速率影响研究

A study on the impact of surface dustfall on the rate of moisture absorption and dehumidification of the ground layer of sculpture

为研究塑像表面降尘对塑像地仗吸湿脱湿速率的影响,本研究采集辽宁义县奉国寺周边土样,制作塑像地仗模拟试样,进行塑像地仗层吸湿脱湿实验,分析塑像地仗层吸湿脱湿过程曲线。结果表明,降尘增加了地仗试样的吸湿量和脱湿量,其作用效果随地仗层含盐量增大而增强;对地仗试样吸湿时间和脱湿时间没有影响。

In order to study the impact of surface dustfall on the rate of moisture absorption and dehumidification of the ground layer of sculpture,this research collected sediments surrounding the Fengguo Monastery in Yixian County,Liaoning Province and prepared samples simulating the condition of the ground layer of sculpture.This article analyzes the curves that illustrate the process of moisture absorption and dehumidification of the ground layer of sculpture.The results show that dustfall increased moisture absorption and dehumidification of the ground layer samples and such an effect was enhanced when the salt contents of the ground layer increased.Dustfall did not have an impact on the time of moisture absorption and dehumidification of the ground layer samples.
