不同施压条件下梗丝填充值与其膨胀效果的相关性

重点研究了不同膨胀效果的梗丝与出烟率的关系,并以出烟率作为判断梗丝膨胀效果的指标,分析得出不同施压条件下梗丝填充值与其膨胀效果之间的关系.试验结果表明膨胀梗丝出烟率与其膨胀效果呈正相关.不同膨胀效果的梗丝在零施压(自然堆积法)和9.8N,30s 2种条件下测定的填充值与其出烟率之间均呈现出较好的相关性,而在施压为9.8N,30s的测试条件下所得的填充值最能准确反映梗丝的实际膨胀效果,因此可将其确定为膨胀梗丝的测定标准;采用自然堆积法测定膨胀梗丝也是一种简便有效的方法.梗丝的自然堆积体积与其膨胀效果的相关性非常明显,自然堆积体积高,其膨胀效果就好.

Correlation between Expansion Effect and Filling Value of Cut Stem under Different Pressure

The relationship between expansion effect and cigarette yield of cut stem was studied in particular. With cigarette yield as the index of evaluating expansion effect, the correlation between expansion effect of cut stem and its filling value under different pressure was obtained. The experimental results showed that cigarette yield and expansion effect of cut stem was positively correlated and the cigarette yields of cut stem with different expansion effect demonstrated pretty good correlation with its filling value under zero pressure (natural bulk status) and 9.8N for 30s, the later condition could be used as a standard for evaluating expansion effect of cut stem, because the filling value determined under this condition most exactly reflected the actual expansion effect of cut stem. The natural bulk volume method was also simple and effective, bigger natural bulk volume meant better expansion effect.
