摘要： 采用HJC-1型环境测试舱模拟室内环境，测量细木工板中甲醛的释放浓度，考察了细木工板结构对甲醛释放的影响，用活性炭、甲醛封闭剂、光触媒和空气触媒控制细木工板中甲醛的释放. 结果表明，细木工板中甲醛释放通道主要为端面，且板材内部结构疏松时甲醛释放剧烈；甲醛封闭剂和活性炭吸附控制细木工板中甲醛浓度的效果理想，平均效率分别为56.05%和52.83%，甲醛浓度在短时间内降到低于Ⅱ类和Ⅰ类民用建筑工程标准.

Abstract: HJC-1 type environment testing chamber was used to simulate indoor environment with block board widely used in building adopted as the testing material. Formaldehyde concentrations in the chamber with different board structures in a certain period were measured. Activated carbon, formaldehyde sealing agent, photocatalyst and air catalyst were used to control its emission. The results indicate that the formaldehyde emission channels of block board are from the side surface, and if the inner structure of block board is loose, formaldehyde will release severely. Formaldehyde sealing agent and activated carbon adsorption control its emission in an ideal effect, their average efficiencies are 56.05% and 52.83% respectively. The concentration of formaldehyde in a short period of time is reduced to the levels below the class II (0.12 mg/m3) and class I (0.08 mg/m3) of civil engineering construction standard.

Key words: formaldehyde, block board, structure, control technology, indoor environment
