| 中文摘要 | 近年由於文具、美容用品、裝潢物品之使用,而造成揮發性有機物(VOC)排放於 室內, 並造成室內空氣品質惡化,雖室內 VOC 可被裝潢用建材予以吸附,惟當通風良好時 ,被吸附 (移除 ) 之 VOC 將再予以脫附 (排放 )。由於裝潢用建材具有相當大的表面積 ( 即氣固界交面 ),可從空氣中吸附揮發有機物, 使空氣中 VOC 的濃度減少 (表面移除、或 吸著作用 ),為能精確地掌握邊界條件,進而獲得良好的室內空氣品質評估模式模擬結果, 需了解 VOC 在室內空氣中的宿命 (fate),因此 VOC 與室內界面間的交互作用, 是一值得 深入研究的課題。 經研究結果得知室內溫度越高,建材的 VOC 吸附能力越低,吸附與脫附 平衡時間越短。 空氣通風量越大,建材 VOC 吸附能力越低,吸附與脫附平衡時間越快。且 室內 VOC 吸附量越低,吸附與脫附平衡時間越長。 三種建材中以地毯之吸附能力最佳,單 位面積吸附量約為 1.92 ∼ 3.29mg/m �插A其次為天花板, 吸附能力則介於 0.35 ∼ 2.24 mgm �插A吸附能力最差的為木板,吸附能力介於 0.34 ∼ 1.55mg/m �插C |
| 英文摘要 | Indoor VOC pollution is due to using the glue, tape, spray, and plastic wood. The construction materials can adsorb VOC since they have a lot of pores. inside. However, the VOC can be easily reentrained becaused it exists airflow in indoor. It is necessary to establish boundary condition of sink effect by studying the materials adsorption characteristics. In the results, the temperature controls the VOC adsorption rate dominantly. The rate is decreased with an increase in temperature and air exchange rate. Whereas, it increase with an increase in concentration. Our results show that the carpet's ability of adsorption is higher than than the ceiling's and the wood slip's. The adsorption capacity of carpet, ceiling, and wood slips is 1.92 ∼ 3.29 mg/m ��, 0.35 ∼ 2.24mg/m ��,and 0.34 ∼ 1.55 mg/m �� respectively. |
