为了考察环境湿度、瓦楞纸板水分与纸板力学性能之间的关系,选择对瓦楞纸板进行不同环境条件的温湿度处理,即试验环境选择温度为23 ℃,相对湿度分别为40%,50%,70%,80%及90%等5 种环境处理条件,样品处理完后按照相关标准测试水分、耐破强度、边压强度。测试结果表明,随着环境相对湿度的提高,纸板水分的增加,纸板的耐破强度及边压强度随之下降,且边压强度的下降程度更为明显。

Corrugated paperboard was treated under different environmental conditions of temperature and humidity,which were temperature of 23 ℃, relative humidity of 40%, 50%, 70%, 80%, and 90%. Water content, bursting strength, and edgewise crush resistance of the sample were determined in accordance with the relevant standards immediately after the treatment. Test results showed that with the humidity increase, the water content increases, the bursting strength and edgewise crush resistance of corrugated paperboard become poor, and the downtrend of edgewise crush resistance is more obvious.
