日本一公司开发出一种可调节室内湿度的新型墙材。这种新型墙材能够自然地吸收室内的湿气或放出湿气。据称,这种新型墙材料用量占室内面积的10％左右,即可将室内湿度保持在60％的最佳状态(气温为25℃、湿度为60％)。以往作为墙材用得最多的是石膏板,但是它的缺点是当室内的湿度未达到90％时就不能吸收水分,当湿度达到90％时墙面已产生霉点。大多数 A company in Japan developed a new type of wall material that can regulate indoor humidity. This new type of wall material can naturally absorb moisture or release moisture in the room. It is said that this new type of wall material accounts for about 10% of the indoor area, so the indoor humidity can be kept at an optimal level of 60% (at an air temperature of 25°C and a humidity of 60%). In the past, gypsum board was used most as a wall material, but its disadvantage is that moisture cannot be absorbed when the indoor humidity is less than 90%, and mildew has occurred on the wall when the humidity reaches 90%. most
