| 摘 要： | 通过氯化天然橡胶(CNR)的穿透干燥试验,探讨风温、风速以及粒径对“胶乳法”CNR干燥速率的影响规律,结果表明,温度和风速对含水量的下降速率影响较大,而粒度对其影响较小。建立了穿透干燥方程,对实验数据进行了拟合,结果显示其吻合性较好。红外光谱分析以及物理性能测试结果表明,“胶乳法”CNR物料的干燥温度应控制在100℃以下。 |

| Abstract: | To study the penetrable drying experiment of tiny Chlorinated Natural Rubber (CNR) granules from latex and discuss the influence of air temperature, air velocity and granularity. The result shows that the drying air velocity and temperature have more obvious influence than granularity on the vaporizing rate of moisture in the granules. To establish the penetrable drying model of CNR and the coefficients of the model were educed from the experiment data. Fitting experimental data, its consistency is very good. The results based on infrared spectrum analysis and physical property test show that the drying temperature of CNR should be controlled less than 100 ℃. |
