家具中有害物质释放机理的研究探讨

The Release Mechanism Study of Harmful Substances in Furniture

家具是引起室内空气污染的主要来源,在加工和使用过程中会持续释放甲醛等各种醛类、烷烃、菇烯、芳香烃类等挥发物,对人体造成一定的危害。本文以甲醛的释放机理为研究对象,重点研究了负压条件对甲醛释放的规律及影响因素,评价了压力差条件、释放通道条件对甲醛释放过程的影响,为有效合理控制家具中有害物质释放提供了基础理论数据。

Furniture is a major source of indoor air pollution, and will continue to release formaldehyde and various kinds of VOC in the processing and use process. It＇s certain harm to human body. The research object is based on the mechanism of formaldehyde release, and focus on the negative pressure conditions on the law of formaldehyde and the influencing factors. The differential pressure condition, release channel conditions on the release of formaldehyde was evaluated. To provide the basic theory of data for effective and reasonable control harmful material release in furniture.
