可用于热固卷筒胶版印刷和轮转凹版印刷的、其定量范围为39~110g/m2的涂布纸(即低定量涂布纸和中等定量涂布纸)的单面涂布(C2S)或者双面涂布(2C2S)含机木浆纸种的方法众多。对这些纸种的市场预测表明:由于当前技术的局限,平均定量和分销模式将不会有任何重大变化。然而,出版商希望降低销售成本,要求降低定量,同时维持纸张质量。本文分析了这些市场需求,发现紧凑型造纸全过程解决方案(Full-Scope Papermaking Solution)适合这种需求。该解决方案的要点为组合应用薄膜涂布技术和较重的预压光,从而推动了机内概念在纸张表面处理中的应用。该解决方案的“印刷产品原料”方法(即配料概念、一体化湿部和用水管理概念以及机内造纸概念)是一种既可以降低定量又保持工艺效率和纸张质量的新方法;该法还可以显著降低生产成本,缩短投资回收期。这种方法最有前途的组合为:配料以热磨机械浆(TMP)为主,生产低定量涂布轮转凹版印刷纸。该文选此组合为例,对其进行了详尽的描述。
One-side coating (C2S) for heatset web offset printing and rotogravure printing on coated paper with a basis weight ranging from 39 to 110 g / m2 (ie low basis weight coated paper and medium basis weight coated paper) or Two-sided coating (2C2S) contains many kinds of organic wood pulp paper. Market forecasts for these paper grades indicate that due to the limitations of the current technology, there will not be any significant changes in the average quantity and distribution model. However, publishers want to reduce the cost of sales and demand a reduction in quantification while maintaining the quality of the paper. This article analyzes these market needs and found that Full-Scope Papermaking Solution fits this need. The key points of this solution are the application of thin film coating technology and heavy pre-calendering in combination, thus promoting the concept of in-machine use in the paper surface treatment. The “raw materials for printing products” approach to the solution (ie concept of ingredients, concept of integrated wet end and water management and concept of in-plant papermaking) is a new way to reduce both the quantity and process efficiency and the quality of the paper; Can significantly reduce production costs and shorten the payback period. The most promising combination of this approach is: The ingredients are based on thermomechanical pulp (TMP) and produce low-volume coated rotogravure paper. The article selected this combination as an example, described in detail.
