摘要
对马尾松浆粕DED漂白进行了研究,结果表明:DED漂白浆粕白度可达90.7%(SBD),浆粕性能良好。对DED漂白中的E段进行强化处理,可以改善漂白浆粕白度。对Ep段进行预处理可以提高DEPD漂白浆粕白度,其中螯合处理(Q)效果最佳。
Producing dissolving pulp from massion pine with DED sequence was investigated. The result showed that the brighmess reached 90.7%（SBD）with better properfes. The Brighmess of dissolving pulp was improved with different enhancing alkali-extraction. The Brighmess of dissolving pulp was improved with different treat methods, especially chelating treatment.
