摘要:随着阔叶木在制浆造纸工业中的广泛应用，阔叶木中的导管组分会在纸张印刷过程中产生导管黏出现象。本文介绍了阔叶木导管的结构和特点，探讨了含阔叶木浆纸张印刷过程中导管黏出的机理，并分析了导管黏出的原因，从原料、打浆、酶处理、湿部化学、施胶、印刷等方面给出了减少导管黏出的方案。

Abstract:The increasing use of fast growing tropical hardwoods has led to a significant tendency of vessel picking in offset printing. The properties of the hardwood vessel elements were introduced. The mechanism and fundamentals of the vessel picking were discussed. The solutions to vessel picking were presented, including raw material selection, refining, fractionation by hydrocyclone, surface sizing and enzyme treatment methods.
