A Study on the growth characteristic of the mould in hygrothermal materials

在日本，作为具有湿度控制性能的内墙组件的湿热材料越来越多地用于建筑施工。虽然有关于这些物品性能的报告，但关于湿热材料上微生物生长造成的潜在污染的信息很少。本研究采用湿热材料进行环境现场测量，考察了湿热材料表面在潮湿暴露条件下霉菌的生长特征。根据现场实测结果可知，湿热材料对霉菌繁殖有促进作用。此外，实验研究证实了使用建议的MGI来评估在不同基质上的限定条件下的霉菌生长的效用。

Hygrothermal materials, interior wall components with humidity controlling properties, are increasingly being used for building construction in Japan. Although there are reports on the performance of these items, little information is available on potential contamination caused by microbial growth on hygrothermal materials. In this study, we conducted field measurements in environment by using hygrothermal materials, and examined the growth characteristics of mould present on the surface of hygrothermal material under conditions of moisture exposure. Due to the field measurement results, it is clear that hygrothermal materials made multiplication of mould promote. Furthermore, experimental studies confirm the utility of using the proposed MGI to evaluate mould growth under defined conditions on different substrates.
