为了分析墙体霉菌生长的条件,以长沙地区实测气候数据为边界条件,应用WUFI-BIO软件模拟房间室内和室外墙面霉菌孢子萌发的特性。结果表明,霉菌孢子的初始含水量对孢子自身萌发的影响小于环境相对湿度。不考虑太阳辐射和雨水侵蚀等不利因素,室外墙体表面除了冬季期间不容易发霉,其他季节都可能促使孢子萌发及菌丝体的生长。室内墙体表面发霉主要集中在5月中旬至6月中旬以及8月至9月中旬这两个时段。在这些霉菌可能生长的时间段,需采取有效措施降低霉菌生长的概率。
In order to analyze the conditions of mold growth on the wall, the climate data of Changsha are used as the boundary condition to simulate the mold spore germination on room's indoor and outdoor walls with WUFI-BIO software. The results show that the actual water content of fungal spores is related to its initial water content, the environmental temperature and the relative humidity. The initial water content of fungal spores has a less impact on spore germination than the relative humidity, whose influence would gradually decrease over time. Without consideration of solar radiation and rainwater erosion, or other unfavorable factors, except in winter, when it is not easy for mold to grow on outdoor walls, in other seasons, spore germination and mycelium growth would be promoted. Moldy indoor walls are mainly found in mid-May to mid-June and August to mid-September. The organic pollutants on indoor wall surface may help the mold spores germinate ahead of time, even enhance their growth. And the entire wall is at an increasing risk of mildew. The growth of mold is harmful to human health. In order to reduce the growth rate of mold during their growth period, it is necessary to take some measures to minimize the indoor relative humidity, and keep the indoor environment in a good condition.
