建材揮發性有機物質逸散行為預測模式之研究

A Study on the Prediction Model for the VOC Emission from BPs

本研究藉由IAQ Model等相關逸散理論解析及實驗量測（小尺寸建材逸散模擬實驗系統）比對的方式，探討位於亞熱帶地區的台灣氣候條件及不同換氣率對建材逸散行為之影響，透過實驗模組變化（30℃、80%RH 及25℃、50%RH）作差異比對，結果發現，在本土氣候下，清漆測試之TVOC總逸散濃度較標準條件下增加123%，在合板測試方面，本土氣候條件之TVOC總逸散濃度較標準條件增加152 %。據此，本文進一步解析單片建材試體（清漆及合板）在試驗艙內之歷時逸散濃度，建立符合本土環境條件之建材「逸散經驗模式」(α-model)，用以推估建材之安全逸散時間，並藉由各組實驗結果的重複擬合(Fitting)後，確認其對於建材揮發性有機物質逸散行為敘述之適用性，以作為後續研訂「綠建材標章制度」、「室內空氣品質管制」、「建築技術規則－－綠建築專章」及推動「住宅性能標章」等相關法令之參考依據。

By fitting the test results of the small scale BPs (Building Products) VOC test with the IAQ MODEL, the influence to the emission behaviors of the BPs from Taiwan environmental factors and changing ACH were tested under two condition set-up: 30℃-80%RH and 25℃-50%RH. As the test results, the TVOC emission from varnish under the Taiwan condition was 123% higher than that under standard condition, while the TVOC emission from plywood under the Taiwan condition was 152% higher than that under standard condition. Furthermore, by amending the 1st-Order Chamber Decay Model with the test results of the emission from single-pieced specimens, stainless steel plate applied with varnish or plywood, the α-model was established. Aiming to predict the VOC concentration from the BPs, the α-model could be a reference to related architectural legislation in Taiwan.
