气力输送系统中炭黑破碎率的试验研究

Experimental Research on Carbon Black Breakage Rate in Pneumatic Conveying System

讨论炭黑破碎的机理及其对橡胶产品质量的影响,并针对炭黑N326的输送,设计了输送压力参数正交试验,确定出获得最小炭黑N326输送破碎率的输送压力参数,并验证其同样适用于其他品种炭黑的输送。另外,还发现了正交试验数据排列不能与实际输送情况相违背的问题,为今后的试验工作积累了宝贵的经验。

The mechanism of the breakage of carbon black and its effect on the quality of rubber product were discussed. The conveying pressure and other parameters were optimized for carbon black N326 by using orthogonal experiment,and the parameters were also suitable for the conveying of other different kinds of carbon black. Moreover,it was found that the testing order in the orthogonal experiment design had to be arranged by considering the actual operated situation,which was a valuable ex- perience for future trials.
