| 摘要:通过对实验纸机（纸机A）与生产纸机（纸机B）不同湿部设备配置与生产比较,分析了影响镂空开天窗安全线防伪纸质量的各种因素及控制要点。实践表明,要想生产出一张合格的镂空开天窗安全线防伪纸,压在安全线上的凸起埋线浆块能顺利地成形、定形、压榨是生产的关键；在这三个工序中的设备配置上“处处都要有真空”是一个保证生产高质量镂空开天窗防伪纸的重要条件。 |
| Abstract:Based on the various wet end equipment configurations and production test of paper machine A and paper machine B, various factors affecting the hollow blank safety line anti-counterfeiting paper quality and control key points were analyzed. The production practice showed that in order to produce a qualified hollow blank safety line anti-counterfeit paper, smoothly forming, settling and pressing of the raised clumps of pulp on the surface of the safety line was critical for production. All of the equipments for those three steps were working under vacuum, it was a important condition to ensure quality open skylight anti-counterfeit paper production. |
