竹炭的烧制工艺与理化性能关系初探

Preliminary Research on the Relationship between Burning Technology and Physical Property of Bamboo Charcoal

在实验室中 ,采用 SX2 - 5 - 12型箱式电炉 ,以 3种不同的工艺和 4种不同的炭化终点温度进行了竹炭烧制工艺与理化性能关系的初步研究。结果表明 :1竹炭的烧制工艺 ,尤其是炭化的终点温度对竹炭性能的影响是明显的。实际生产中 ,根据窑型进行工艺优化是完全必要的 ;2炭化的终点温度越高 ,挥发分含量与精炼度等级值越小 ,灰分与固定炭含量增加 ,电导率增大 ,竹炭密度相应提高 。

In the lab, research on the relationship between burning technology and physical property of bamboo charcoal, using SX2 5 12 electrical stove, with three different technology and four different carbonized final temperature. The result shows (1) Bamboo charcoal's burning technology; especially the final temperature influences its property obviously. So in the real production,it is necessary to adjust the shape of kiln. (2)The higher the final temperature is, the smaller the volatility volume and refining degree are. If the content of the ash and fixed charcoal is increased, the conductivity rate rises too. At the same time,the density of bamboo charcoal will be raised. And the calorific value tends to be stable. Key words Bamboo charcoal; Burning technology; Physical property
