| 中文摘要: |
| 对瓦楞纸板压线进行PVA局部涂覆前后，在相对湿度为25%，35%，50%环境下测定了其耐折性能和耐破度，分析了PVA局部涂覆对“爆线”现象的影响。结果表明：在相对湿度为25%的条件下，PVA局部涂覆对“爆线”现象改善不明显，在相对湿度为35%和50%时，PVA局部涂覆可有效改善瓦楞纸板“爆线”现象。 |
| 英文摘要: |
| The pressed line of corrugated board was locally coated with PVA coating, and the folding endurance and bursting strength of PVA-coated and non-coated corrugated board was tested in environmental humidity of 25%, 35%, and 50% respectively. The influence of local coating on corrugated board cracking phenomenon was analyzed. The results showed that under the relative humidity of 25%, PVA-coated board does not show obvious improvement on the "Burst line" phenomenon; under relative humidity of 35% and 50%, PVA-coated can effectively change the corrugated cardboard "burst line" phenomenon. |
