造纸法再造烟叶涂布液流变行为的研究

Studies on rheological behavior of paper-making reconstituted tobacco' coating liquid

以造纸法再造烟叶产品A均为基础，考察时间、温度、波美度等因素对涂布液A黏度的影响．结果表明：随着流动时间的增长，体系波美度大于25。B6时涂布液A黏度逐渐升高，体系波美度低于25°Be时涂布液A黏度几乎无影响；涂布液A的波美度对体系黏度的影响较大．由此得到造纸法再造烟叶在生产过程中的适宜涂布条件为：涂布液A波美度24—25°Be，体系温度60-65℃．

The impact of time, temperature and Baume degree on the viscosity of sizing liquor A on the ba- sis of paper-making reconstituted tobacco product A was studied. The results showed that,with the increase of flowing time, the viscosity of coating liquid A increased gradually when Baume degree was over 25°Be, while it had no influence to the viscosity when Baume degree lower than 25°Be; and Baume degree had great influence on the viscosity of coating liquid. It could be concluded that the following favorable coating conditions should be satisfied for paper-making reconstituted tobacco manufacturing ： Baume degree of coat- ing liquid was about 24 ~ 25~B6 and temperature was 60 - 65 ℃.
