摘要

为了准确地检测地采暖环境下木质地板的甲醛释放量，研制一种模拟地采暖环境的模拟舱。主要介绍该地采暖环境模拟舱的结构组成和工作原理，以及运行测试结果。结果表明，该模拟舱的温度及相对湿度波动范围都在1 m,3,气候箱法允许范围内，地板上下表面存在温度梯度，可模拟真实的地面辐射供暖情况。应用模拟舱对浸渍纸层压木质地板和多层实木复合地板的甲醛释放检测值，高于常规1 m,3,气候箱法检测值，且低于气候箱整体加热方式下的检测值，能更真实地反映地采暖用木质地板的甲醛释放情况。

Abstract

In order to accurately evaluate formaldehyde emission from wood-based flooring in ground heating system, a radiant heating simulation chamber was developed. This paper mainly introduced the structure and working concept of the device. Tests were performed in the radiant heating simulation chamber. The test results showed that the fluctuation range of temperature and relative humidity was within the allowable scale of the 1 m,3, climate chamber method. There was a temperature gradient on the upper and lower surfaces of floor heating, which was consistent with the actual radiant heating system. The application test results showed that the formaldehyde emission measured by the simulated chamber was higher than that measured by the conventional 1 m,3, climate chamber method, and lower than that measured by the climate chamber integral heating method, which presented truly formaldehyde emission of wood flooring used in ground heating system.
