In this experiment, lignite was refined and processed through binderless briquette preparation process from low-rank coal and became briquette. Then, lignite and its briquette were pyrolysed as materials to compare the nature of their pyrolysis. In this study, the experiment was carried out through a lab tube furnace, at a heating rate of 10 ~C/min, and the gas was analyzed and compared, which was collected at different temperatures. The results show that: in the pyrolysis temperature of 550-850 ℃, the semi-coke yield of briquette is 2%-6% higher than lignite, the tar yield of briquette is 2%-3% higher than lignite and the gas yield of briquette is 4%-9% less than lignite. The time required for complete release of the briquette is about 20 min less than lignite. The components in the pyrolysis gas of lignite and its briquette are the same, and their variation with the pyrolysis temperature is similar. 展开更多

新漆艺教学理念

本文阐述的是新漆艺的教学理念,是笔者从近几年的教学讲义中整理的第一手资料,文章认为漆艺教学必须坚持在传统工艺上实验和创新,反对将工艺教学重新权威化和标准化,因为那会使工艺丧失它原本就有的变化和创新的活力。
关键词 新漆艺 实验的工艺 传统的延续 传统的突变 工艺的诗歌
