Detailed analysis of the wood at home and abroad for the raw material preparation Woodceramics and non-timber plant for the preparation of plant-based ceramic status quo, the feasibility of new plant material - crop waste cotton stalks as raw material bioceramics and Experimental study of the system. Using cotton stalk powder mixed with phenolic resin the thermoforming and nitrogen protection vacuum sintering technology roadmap, analyzed the nature of raw materials, the molding process, the sintering temperature, the ratio of raw materials of cotton stalk ceramic carbon yield, volume shrinkage, mechanical properties, The degree of graphitization and parallel comparison with poplar ceramics to explore the characteristics of the cotton stalk ceramic preparation process, product performance and possible uses. By thermal gravimetric analysis of the raw materials as the basic raw material for manufacturing plant based ceramic material, cotton stalks and poplar have similar performance and production conditions, phenolic resin weight loss rate is much lower than the cotton stalk, resin plant based ceramics plays an important role in the manufacture of materials. By molding and sintering tests confirmed the cotton stalk powder preparation of bio-ceramic is feasible, in the process, the basic performance of the products and their impact factors with ordinary wood similar. The test confirmed that the sintering temperature are important factors to affect cotton stalk ceramic carbon yield, the higher the temperature, lower carbon yield. However, after reaching a certain temperature, charcoal yields change decreases. Raw material ratio under the same conditions, with increasing temperature, the volume shrinkage of the cotton stalk ceramic decreases, and its true density is increased; under the same temperature conditions, with the increased amount of phenolic resin, will reduce its volume shrinkage, true density increases. Cotton stalk ceramic bending strength increases with the increase of the amount of glue and the sintering temperature and improve. Analysis by X-ray diffraction patterns of carbonization temperature rise, cotton stalk ceramic graphite of microcrystalline average layer spacing d002 reduce the degree of graphitization enhancement, its structure tends structured; phenolic resin glue, cotton stalk ceramic an average layer spacing d002 of graphite crystallites decreases, also enhanced the degree of graphitization, but without carbonization temperature is less obvious. This study, not only for the natural plant materials, especially crop straw functional eco-friendly materials to explore new ways and new process routes used, process parameters, and the basis of analysis, but also for the entire biomass research and development of ceramic and references.
