| Summary: | 碩士 === 國立臺北科技大學 === 建築與都市設計研究所 === 101 === The objective of this study was used emission from multi-layered building materials(multi-layered BMs) to predict adhesive emission coefficients. We used the Multi-Layered of adhesive(Sandwich Materials) between the dry building material(Substrate Materials) and dry building material(Surface Materials).The Small Scale Chamber System was ventilated with conditioned air, temperature :25℃、35℃ and humidity 50%, air change rate 0.5 h-1.To assay to formaldehyde(HCHO) and Total Volatile Organic Compounds (TVOC).
The result showed that had three Characteristics of TVOC and HCHO .The high temperature had stronger effect for chemical emission. The formaldehyde emission on 35℃ is higher than 25℃(1.97 folds), TVOC emission on 35℃ is higher than 25℃(1.34 folds). There had similar concentration with Multi-Layered BMs and surface material (1.2 folds), HCHO emission in Multi-Layered was major from Surface material (Engineered Wood), and TVOC are Sandwich Material(superglue). The study establish Predicted Coefficients for Multi-Layered BMs of Substrate, Sandwich, Surface materials, and understand Predicted Coefficients for Multi-Layered BMs on 25℃ and 35℃. The temperature from 25℃ rise to 35℃,the Sandwich material of formaldehyde emission increased 6%, the Substrate material decreased 1%, the surface material decreased 3%, the temperature in 25℃ to 35℃,the Substrate material of TVOC emission increased 1%, the Substrate material and surface material decreased 1%. This study through compare the emitted predicted value with experimental data, most of the values are 「Excellent Predictive Accuracy」in MAPE.
