本研究探討溫熱環境因子下，對建材表面吸附揮發性有機物之影響。藉由相關文獻調查分析，了解台灣地區室內熱溼環境氣候特性，以小型環控箱改變溫度、溼度環境變因設定，供應標的污染物(甲醛)至環控箱中，進行乾、濕式建材之吸附、脫附試驗。透過實驗過程中甲醛濃度採樣分析，探討溫、濕度與建材吸附之相互影響程度。
本研究主要可歸納以下結論 :
(一)溫溼度變因下建材表面對甲醛吸附之影響
透過實驗分析，乳膠漆對甲醛之吸附隨環境溫度升高吸附率呈現下降趨勢，溫度越高吸附率降低程度越明顯; 環境相對濕度增加，乳膠漆吸附程度亦有下降趨勢。
(二)乾濕式建材對甲醛吸附之變化
於乳膠漆(濕式建材)吸附實驗結果顯示，乳膠漆隨吸附時間增長，吸附量呈現一較為穩定之下降趨勢。在竹碳板(乾式建材)吸附實驗結果顯示，竹碳板初期吸附量呈現上升趨勢，至吸附中期吸附量明顯下降，而後再趨於穩定狀態。由本研究實驗可知，本試驗所使用之兩種建材吸附行為並非呈單一吸附模式，建材吸附歷程吸附量隨建材組成、種類等而有不同吸附型態。
(三)建材對甲醛吸附及再脫附模式
乳膠漆吸附試驗環境溫度為25℃、28℃之實驗模組，於吸附試驗階段後進行升溫至35℃再脫附試驗，環控箱經採樣分析結果發現濃度有明顯上升情形，濃度上升顯示當溫度上升幅度大時建材表面吸附之甲醛受溫度激發而產生大量脫附現象。於環境溫度31℃之實驗模組，由於升溫至35℃之間的升溫幅度不大，受激發釋出甲醛的情形並不顯著。
(四)建材吸附行為對改善室內空氣品質可行性
透過溫度、濕度環境變異因子設定所進行之各組實驗，經由採樣分析後，藉由計算吸附通量則能看出每小時每單位面積下所能吸附之量，乳膠漆在溫度25℃、28℃下各組試驗吸附通量皆能達到85µg/(m²*h)以上。以25℃-50%RH表現最好吸附通量可達124.94 µg/(m²*h)，於每小時每單位面積下，乳膠漆可吸附124.94微克之甲醛物質。

This study investigated the impacts of thermal environmental factors on VOCs adsorption for the surface of building materials. According to literature reviews, a small scale chamber with fixed pollutant (HCHO) was set up to simulate the indoor environment for the testing of HCHO adsorption and desorption from dry and wet building materials. Through experiments and analysis, this study aimed to probe the effects of temperature and humidity on the adsorption of HCHO for building materials.
The following are the conclusions of this research:
(1)Effects of temperature and humidity on the adsorption of HCHO for the surface of building materials
The experimental results show that the adsorption rate of HCHO for latex paint decrease by the rise of temperature. The higher the temperature, the less the adsorption rate of HCHO. Furthermore, the adsorption rate of HCHO for latex paint also decrease by the rise of relative humidity.
(2)Changes of the adsorption of HCHO for dry and wet building materials
The results show that the adsorption quantities of latex paint (wet building material) decrease at a stable rate when the adsorptive time is increased. Moreover, the adsorption quantities of bamboo carbon plate (wet building material) increase in the beginning and then decayed steadily during a later stage. As a result, we find out that the adsorption behaviors of HCHO for the two building materials are not just present a single state. The adsorption quantities might have different adsorption states depending on compositions, types, and other factors of building materials.
(3)Models from HCHO adsorption to HCHO desorption for building materials
In the experiments of latex paint adsorption, the temperatures are set as 25 and 28℃. After the experiments of adsorption, both of the temperatures are changed to 35℃ to conduct the experiments of desorption. The results show that the HCHO concentrations of the small scale chamber increase obviously and then desorb greatly when the temperature is increased at a wide range, whereas the HCHO desorption varied indistinctively when the temperature is changed from 31 to 35℃.
(4)Proposed the adsorption behaviors of building materials to improve indoor air exchange rate
According to the adsorption quantities of building materials in the adsorption experiment, we calculate the sorption flux. The 4 cases(the temperatures are set as 25 and 28℃) of latex paint experiments of the sorption flux are higher than 85μg/ (m²*h) level. In parts of latex paint (25℃, RH=50%), the average rate of the sorption flux is 124.94μg/ (m²*h). It means that the latex paint(25℃, RH=50%) can adsorb HCHO 124.94μg per hour per square meter.
