Abstract

The present work focuses on the effects of sodium percarbonate and hydrogen peroxide as reinforcing agents for the oxygen delignification of old corrugated container paper (OCC). The chemical and crystalline structure, physical and mechanical properties and the optical properties were investigated in OCC papers delignified using reinforced oxygen delignification methods. The relative degradation rates were determined at 4.02% for oxygen delignification reinforced with sodium percarbonate and 0.62% for oxygen delignification reinforced with hydrogen peroxide at a 2% alkali charge. The results showed that paper sheet properties following oxygen delignification reinforced with hydrogen peroxide were better than for those following oxygen delignification reinforced with sodium percarbonate and pure sodium percarbonate. It was determined that the whiteness value was higher following oxygen delignification reinforced with sodium percarbonate rather than any of the other reinforcing agents, while the highest ISO brightness value was found following oxygen delignification reinforced with hydrogen peroxide.

旧瓦楞纸板(OCC)纤维增强氧脱木质素方法的比较

本文主要研究过碳酸钠和过氧化氢作为补强剂对旧瓦楞纸箱纸氧脱木质素的影响。采用增强氧脱木质素法对OCC进行脱木质素处理，研究了OCC的化学结晶结构、物理力学性能和光学性能。过碳酸钠增强氧脱木质素的相对降解率为4.02%，过氧化氢增强氧脱木质素的相对降解率为0.62%。结果表明，过氧化氢增强氧脱木质素的纸张性能优于过碳酸钠和纯过碳酸钠增强氧脱木质素的纸张。结果表明，用过碳酸钠增强氧脱木质素后的白度值高于其他增强剂，而用过氧化氢增强氧脱木质素后的ISO亮度值最高。
