| 目的 分析真空镀铝纸不同因子对印刷品爆裂的影响程度， 为更好地管控印刷品外观质量提供一定的参考。 方法 采用铁质爆墨检测仪对 36 种真空镀铝纸印刷品进行爆裂检测。 结果 不同原纸类型其印刷品爆裂程度不同 ； 原纸水分质量分数控制在 5%～ 6%、转移胶水（聚氨酯）玻璃化温度与上胶量分别为 -5～ 5 ℃和 7.5～ 8.5 g/m2及转移涂料（丙烯酸）涂布干量为 1.2～ 1.3 g/m2时， 其印刷品为最佳状态，无爆裂现象。 结论 真空镀铝转移纸中每个环节均会对印刷品爆裂有一定影响。 |

| Abstract: |
| Objective In order to better manage and control the print surface, the different factors of vacuum aluminum transfer paper were analyzed for their influences on print burst. Methods Iron blast ink instrument was applied to determine the 36 prints of vacuum aluminum transfer paper. Results The degree of print burst was different for different paper types. When the paper moisture was controlled in the range of 5%～ 6%, the glass transition temperature of polyurethane transfer adhesive was -5～ 5℃ , the glue dose of polyurethane transfer adhesive was 7.5～ 8.5 g/m2, and the coating weight of acrylic acid transfer coating was 1.2～ 1.3 g/m2, the prints were in the best state and there was no burst. Conclusion Each part of vacuum aluminum transfer paper had certain influence on print burst. |
