铜版纸的灰份测定及灰份对各项主要指标的影响

Testing Ash of Art Paper and Effect of Ash on Art Paper Physical Properties

测定以CaCO_3为填料的中性施胶生产的同一克重有光铜版纸的总灰份,并检测铜版纸的厚度、内结合强度、耐折度、拉毛、不透明度、花斑、平滑度、油墨吸收性及印刷光泽。通过数据检测分析认为随着总灰份的提高,厚度、内结合强度、耐折度和拉毛降低;不透明度、花斑、平滑度、油墨吸收性及印刷光泽提高。

Testing ash of the same basis weight neutral sizing Art Paper.Testing thickness, in-ternal bond strenghth,endurance, dry pick,opacity, mottling,smoothness,K＆N and print gloss of Art Paper.With analyzing these datas,it was found that ash had important effect on thes-e physical properties.The higher ash caused lower thickness, lower internal bond strenghth,lower endurance and lower dry pick.The higher ash caused higher opacity,higher mottling,higher smoothness,higher K＆N and higher print gloss.
