中文摘要:以秸秆纤维轻质墙体为研究对象,分析其结构和组成及其对材料高温性能的影响;通过TG-FTIR分析,研究了高温作用下的秸秆纤维墙体材料的物理化学变化过程。在上述基础上,针对该种新型建筑材料进行了烧失量实验,利用DRS2.6数据回归分析软件,建立了火灾温度-烧失量的一元回归模型。同时,以200mm厚的秸秆纤维外墙保温板为例,在ISO9705标准火灾实验间对温度-烧失量回归模型进行了校验。结果表明:回归方程准确可信,可用于火灾后各部位的温度变化情况、起火原因的认定和灾后强度评估。

Abstract:Straw fiber wall structure is a new structural system with properties of lightweight and energy-saving, heat preservation and sound isolation. Firstly, the impact of chemical component, structure on basic thermal performance such as activation energy, heat productivity, heat release rate was studied in details. Secondly, the chemicophysics reaction in high temperature were studied through TG-FTIR experiment. Finally, the linear stepwise regression model about fire temperature and loss on ignition was established based on loss on ignition experiment and DRS2.6 software analysis system. Furthermore, a 200mm thickness straw fiber external thermal insulation plate was chosen and burned in independent designed ISO9705 standard fire test room in order to verify the accuracy of the regression model. The results show that the model is correct and can be applied to the real engineering computation and assessment.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
