回收废纸对于欧洲造纸工业来说是最重要的原料。废纸浆在各种高档纸中的应用受到其杂质含量的限制,这些杂质由废纸原料带入到生产系统中。这些杂质的一个重要组分是印刷油墨,主要来自废旧印刷品。这些油墨必须从纸料中去除,以便保证所生产纸张的光学性能与原生浆(如木浆)为原料所生产纸产品的光学性能相近。目前,在柔版印刷和数码印刷中通常使用的水性油墨的去除成为一个很
Recycled waste paper is the most important raw material for the European paper industry. Waste paper pulp in a variety of high-grade paper applications by the content of impurities, these impurities from the waste paper raw materials into the production system. An important component of these impurities is printing inks, mainly from used print. These inks must be removed from the paper stock in order to ensure that the optical properties of the paper produced are comparable to the optical properties of paper products produced from virgin pulp, such as wood pulp. Currently, the removal of aqueous inks, commonly used in flexographic and digital printing, becomes a
