Autor: Xin Shi, Hao Shen, Shenglei Qin, Yangguang Liu, Xiaoshuang Shen, Demiao Chu, Shengquan Liu

Publikováno v: BioResources, Vol 19, Iss 2, Pp 3436-3460 (2024)

Ammonium dihydrogen phosphate (ADP) is a nitrogen-phosphorus-based inorganic flame retardant that is environmentally friendly and non-toxic. Wood treated with ADP has enhanced thermal stability and flame retardancy. Compounding ADP with Acid Red 3R d

Thermal Modification Intensity of Heat-treated Poplar Wood. Part 2: Characterization and Predication from Outside to Core Layers

Autor: Yang Li, Tao Yao, Yong Zhu, Shengquan Liu, Zuju Shu, Redžo Hasanagić, Fathi Leila, Demiao Chu

Publikováno v: Drvna Industrija, Vol 75, Iss 1, Pp 31-42 (2024)

Based on the previous study of the heat-treated wood at 0-3 mm surface layer, this study focuses on the transition of thermal modification intensity on 160-220 °C heat-treated poplar from surface to core layers. The color change was evaluated by CIE
