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

湿热材料是一种具有湿度控制特性的内墙部件，在日本越来越多地被用于建筑施工。尽管有关于这些物品性能的报告，但关于微生物在湿热材料上生长造成的潜在污染的信息很少。在本研究中，我们利用湿热材料在环境中进行了现场测量，并研究了湿热材料表面霉菌在潮湿暴露条件下的生长特性。现场测试结果表明，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所提出的MGI来评估不同基质上特定条件下的霉菌生长的有效性。

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.
