摘要
本试验介绍了一种液体荧光消除剂的应用特性,研究了反应温度、混合时间和消除剂用量对荧光消除效果的影响。试验得出该荧光消除剂的最佳应用条件为反应温度80℃,混合时间10min,荧光消除剂用量3.0%。此条件下,该荧光消除剂可将纸页的荧光白度F降低到2.0%以下,R457白度的损失为6.3%。
This paper focus on the application of a liquid fluorescence quenching agent on paper pulp. Several influence factors such as reaction temperature, mixing time and dosage of fluorescence quenching agent were stuied. The best applicable conditions were： reaction at 80℃, mixing for 10 min, dosage of the fluorescence quenching agent 3.0%. At these conditions, the fluorescence value of paper was lower than 2.0% , the decrease of R457 brightness was 6.3 %.
