Abstract

Indoor air quality is a very important environmental factor in modern society. However, air pollutants generated from various interior construction materials significantly affect the human body, including formaldehyde (HCHO) and volatile organic compounds that threaten public health by deteriorating indoor air quality. Effective in removing these harmful substances are porous materials, such as woodceramics. In this study, charcoal, a porous material, was added to rice husk, an agricultural by-product, and sawdust generated during the sawing process to prepare boards and ceramics at different mixing ratios, and the HCHO deodorization performance and far-infrared emission characteristics were measured. As the mixing ratio of charcoal increased, the deodorization rate of the boards and ceramics tended to increase. Overall, the deodorization rate was measured to be 80% to 90%, indicating that the boards and ceramics prepared with charcoal are suitable to be used for the purpose of deodorization. The effect of the material mixing ratio on far-infrared emissivity and emission power was insignificant.

木屑、木屑和木炭制备陶瓷的甲醛除臭效果和远红外发射特性：材料配比的影响

室内空气质量是现代社会一个非常重要的环境因素。然而，各种室内建筑材料产生的空气污染物对人体产生了重大影响，包括甲醛和挥发性有机化合物，它们通过恶化室内空气质量威胁公众健康。有效去除这些有害物质的是多孔材料，如木陶瓷。本研究将木炭这种多孔材料添加到农业副产品稻壳和锯切过程中产生的锯末中，以不同的混合比例制备板材和陶瓷，并测量了六氯环己烷的除臭性能和远红外发射特性。随着木炭混合比例的增加，板材和陶瓷的除臭率有增加的趋势。总的来说，除臭率测量为80%至90%，表明用木炭制备的板和陶瓷适合用于除臭目的。材料配比对远红外发射率和发射功率的影响不大。

期刊介绍： The Journal of the Korean Wood Science and Technology (JKWST) launched in 1973 as an official publication of the Korean Society of Wood Science and Technology has been served as a core of knowledges on wood science and technology. The Journal acts as a medium for the exchange of research in the area of science and technology related to wood, and publishes results on the biology, chemistry, physics and technology of wood and wood-based products. Research results about applied sciences of wood-based materials are also welcome. The Journal is published bimonthly, and printing six issues per year. Supplemental or special issues are published occasionally. The abbreviated and official title of the journal is ''J. Korean Wood Sci. Technol.''. All submitted manuscripts written in Korean or English are peer-reviewed by more than two reviewers. The title, abstract, acknowledgement, references, and captions of figures and tables should be provided in English for all submitted manuscripts.
