本文分别以欧美杨AS-AQ浆为研究对象,探讨添加过氧化氢、二甲基亚砜、氨基磺酸、葡萄糖等四种助剂,对减少二氧化氯漂白用氯量起到的作用。研究结果表明:当用氯量为1.0%时,各种助剂的最佳用量为,过氧化氢0.4%～0.6%、二甲基亚砜1.0%、氨基磺酸1.0%、葡萄糖1.0%;当四种助剂用量相同时,添加过氧化氢的纸浆性质最好,二甲基亚砜的最差;对后续DEPP漂白,未添加助剂的用氯量为1.4%时,添加助剂过氧化氢、二甲基亚砜、氨基磺酸、葡萄糖可节约用氯量分别为:0.2%、0.6%、0.6%、0.1%,其中添加过氧化氢和葡萄糖比对照浆的白度略高,添加二甲基亚砜和氨基磺酸比对照浆白度低1%ISO左右。
In this paper, the European and American Yang AS-AQ pulp as the research object, to explore the addition of hydrogen peroxide, dimethyl sulfoxide, sulfamic acid, glucose and other four additives, to reduce the amount of chlorine dioxide bleaching played a role. The results show that when the amount of chlorine is 1.0%, the optimum dosage of various additives is 0.4% ~ 0.6% of hydrogen peroxide, 1.0% of dimethyl sulfoxide, 1.0% of sulfamic acid and 1.0% of glucose. When the amount of the four auxiliaries were the same, the pulp with hydrogen peroxide added had the best quality and the dimethylsulfoxide with the worst value. For the subsequent DEPP bleaching, when the amount of chlorine with no added additives was 1.4% Hydrogen peroxide, dimethyl sulfoxide, sulfamic acid, glucose can save chlorine were: 0.2%, 0.6%, 0.6%, 0.1%, which added hydrogen peroxide and glucose whiteness slightly higher than the control, Add dimethyl sulfoxide and sulfamic acid than the control whiteness of about 1% lower ISO.
