| 目的 探究不同烘箱温度和风速对水性油墨干燥过程的影响。方法 对水性油墨热风干燥过程进行数值模拟，分析不同温度和风速下的油墨干燥状态，设置烘箱在5个不同水平风速和温度下，使用同一种油墨和纸张进行烘干实验。然后从样本的耐摩擦度、动摩擦因数和静摩擦因数来检测油墨的干燥质量。结果 数值模拟结果表明了水性油墨干燥符合两阶段干燥原理，温度和风速会影响油墨内部水分流失和温度传递。对数值模拟结果进行了实验验证，在温度为60 ℃和风速为7 m/s时具有良好的干燥质量，过高或过低的风速和温度都会降低质量。结论 温度与风速会影响水性油墨的印刷质量，提升或降低温度和风速并不会提升干燥效果，为实际生产中干燥参数的设置提供了依据。 |

| The work aims to investigate the effects of different oven temperatures and wind speeds on the drying process of water-based inks. Numerical simulation of hot wind drying process of water-based inks was carried out to analyze the drying state of the ink at different temperatures and wind speeds. The oven was set up at five different levels of wind speeds and temperatures, and the same ink and paper were used for drying experiments. And finally the ink drying quality was detected from the abrasion resistance, dynamic friction coefficient and static friction coefficient of the samples. The numerical simulation results showed that the drying of water-based inks conformed to the two-stage drying principle, and temperatures and wind speeds affected the internal moisture loss and temperature transfer of the ink. The experiments verified the numerical simulation results that the temperature of 60 ℃ and wind speed of 7 m/s had good drying quality, and too high or too low wind speed and temperature would reduce the quality. It is concluded that temperature and wind speed affect the printing quality of water-based inks, and raised or lowed temperature and wind speed do not improve the drying effect, providing a basis for setting the drying parameters in actual production. |
