项目摘要
Wastes from demolished buildings and concrete-form work consist of various components. Charcoal of wood material is available from the process of burning of these mixed wastes. This study aimed to attach new functional property to the mixed wastes and investigate the wood charcoal carbonized by ultrahigh-temperature processing by two-step carbonization.Though the carbonization depends on the condition of atmosphere and temperatures, anatomical structure of wood is considerably maintained even at high temperature. Change of the crystal structure and adsorption property of formaldehyde are dependent on the carbonization temperature.Conical carbon material was formed by heating Japanese cedar charcoal at more than 2500℃ under Ar gas atmosphere. This newly found material has very different feature and thermal stability from known wood charcoals because of difference of the formation. The exothermal peak of 2500℃ treated charcoal, which includes conical carbon material, with DTA measurement … More under air is broader than those of known wood charcoals. This fact indicates that the region for oxidizing temperature is wide. Isolation of the conical carbon material from charred wood cell wall might be achieved by controlling oxidization temperature and time.Waste gypsum board of various hydrates was prepared by treating at various temperatures. The powdered gypsum board and wood charcoal was mixed with various ratios and reformed as boards and absorption and mechanical property were investigated. Powdered gypsum board treated at 500℃ was anhydrite. The hydration state was not changed by moisture condition and drying temperature. The moisture content of the mixed material increased with the increase of the ratio of wood charcoal. In the case of mixed wastes monitoring the process of combustion and charcoalization is at least necessary for application. For the modification into new materials two-step carbonization is useful because various volatile gases are generated during charcoalization process. Less
拆除建筑物和混凝土形式的废物由各种组件组成。从燃烧这些混合废物的过程中可以获得木材材料的木炭。这项研究旨在将新的功能特性附加到混合废物上,并通过两步碳化来调查通过超温度加工碳化的木木炭。尽管碳化取决于大气和温度的状况,木材的解剖结构也被视为即使在高温下也被视为维持。甲醛的晶体结构的变化和添加特性取决于碳化温度。碳材料是通过在AR气体气氛下加热日本雪松木炭以2500℃的2500℃加热而形成的。由于形成的差异,这种新发现的材料与已知木炭的特征和热稳定性非常不同。 2500 c木炭的水温峰(包括临床碳材料)进行了DTA测量……在空气下,木炭比已知的木炭的空气更宽。这一事实表明,用于氧化温度的区域宽。通过控制氧化温度和时间,可以从烧焦的木细胞壁上分离临床碳材料。通过在各种温度下处理各种水合物的废物石膏板。将石膏板和木炭粉与各种比率混合,并改革了板,滥用和机械性能。处于500℃处理的石膏板是硬脂石。水分状况和干燥温度不会改变水合状态。混合材料的水分含量随木木炭比的增加而增加。在混合废物的情况下,监测混合物的过程,至少对于应用是必需的。对于新材料的修改,两步碳化是有用的,因为在炭化过程中产生了各种挥发性气体。较少的
