日本大建工业公司最近成功地开发了一种具有能调节室内湿度功能的新型墙体材料。该材料能够自然地调节室内湿度。据称这种墙体材料只需使用室内面积的10％左右,即可将室内湿度保持在60％的最佳状态。据认为居室内的最佳状态一般为气温25℃、湿度60％。 目前,作为墙体材料用得最多的是石膏板,但是它的缺点是当室内的湿度未到90％,它就 Japan’s Dajian Industrial recently successfully developed a new type of wall material that can regulate indoor humidity. The material can naturally adjust the indoor humidity. It is said that this kind of wall material only needs to use about 10% of the indoor area, so the indoor humidity can be maintained at the best level of 60%. It is considered that the best condition for living indoors is generally 25°C and 60% humidity. At present, gypsum board is the most used wall material, but its disadvantage is that when the indoor humidity is less than 90%, it
