| 目的 评价环境相对湿度对瓦楞纸箱质量的影响。方法 在23 ℃和相对湿度为50%，70%，98%的环境中，比较3层、5层和7层瓦楞纸箱的抗压强度、耐破强度以及吸湿率等性能指标。结果 瓦楞纸箱的吸湿率和含水率随环境湿度的升高而增大；当环境相对湿度在50%~70%时，瓦楞纸箱的耐破强度、边压强度及抗压强度等性能保持稳定；当环境相对湿度达到98%时，3层、5层和7层瓦楞纸箱的耐破强度比相对湿度50%条件下分别降低了53.8%，74.1%和76.3%，边压强度分别降低了71.4%，70.3%和77.5%，抗压强度和堆码层数显著下降；7层瓦楞纸箱的防潮耐压能力优于3层和5层。结论 高湿度会引起瓦楞纸箱的性能指标显著降低，功能受损。 |

| The work aims to evaluate the effect of ambient relative humidity on qualities of corrugated carton. The performance indicators such as compressive strength, bursting strength and moisture absorption rate of the 3-layer, 5-layer and 7-layer corrugated cartons were compared at 23 ℃ and the relative humidity of 50%, 70% and 98%, respectively. The moisture absorption rate and moisture content of the corrugated cartons were enhanced with the increase in the ambient humidity. The bursting strength, edge compressive strength, compressive strength and other performances of the corrugated carton remained stable when the ambient relative humidity was 50%~70%. When the relative humidity reached to 98%, the bursting strengths of the 3-layer, 5-layer and 7-layer corrugated cartons at the relative humidity of 50% were respectively reduced by 53.8%, 74.1% and 76.3%; and the edge compressive strengths were reduced by 71.4%, 70.3% and 77.5%, respectively. The compressive strength and stacking layers were significantly reduced. The moisture resistance and pressure resistance of the 7-layer corrugated carton were better than those of the 3-layer and 5-layer corrugated cartons. High humidity can cause significantly reduced performance indicators and damaged functions of the corrugated carton. |
