摘要
选取自制的3种褐煤型煤防水添加剂,通过成型及防水等实验研究,对比型煤产品发热量、冷压强度、浸水强度等指标后,优选出最佳褐煤型煤防水添加剂。通过改变添加剂配入量,确定最合理配入比例,并进行规模化生产实验。结果表明:添加褐煤型煤高效防水添加剂后,褐煤型煤产品浸水强度可达558 N/个,浸水复干强度可达540 N/个;同时,该防水添加剂还可提高成型褐煤的冷压强度及热强度,且可以降低灰分及硫分等不利组分的含量。
Taking three kind of selfdeveloped waterproof additive of lignite briquette as research objects, carried out briquetting and waterproof experiments. Investigated the calorific value, cold compressive strength and compressive strength after immersion of beriquette products, then selected the most efficient waterproof additive. Determined the best blending ratio by changing the additive amount. The results show that, with the help of additive, the compressive strength after immersion and redrying strength of briquette can reach up to 558 N and 540 N respectively, the cold compressive strength and hot strength are higher, ash and sulfur content are lower than lignite briquette without additive.
