生皮宣的生产与加工

Production and processing of raw Xuan paper

为了开拓制造宣纸原材料向多元化方向发展,对生檀皮的生产与加工进行了研究,主要是生檀皮的蒸煮与漂白,在此基础上开发生产了生皮宣纸。本文仔细分析了生皮宣纸研发成功的主要成果:⑴成功运用二次加碱蒸煮新工艺解决了生檀皮聚戊糖、胶汁、木素含量高、皮质老化发脆难于蒸煮的重大难题,取得了二次加碱蒸煮檀皮技术成果。⑵成功运用二段漂白技术解决了生檀皮浆难于漂白的难题,既达到漂白白度,又提高纤维强度,取得了在檀皮浆漂白上的创新成果。生檀皮加工生产的浆料纤维长、强度高,浆料白度符合宣纸制作工艺标准要求,生产制作的宣纸各项物理指标均达到或超过宣纸国家标准。

In order to diversify raw materials for xuan paper producing,this paper conducts a survey on the production and processing of raw sandalwood bark,especially on its digestion and bleaching.It provides a guide for the production of raw Xuan paper.Two major achievements have been achieved in this process.Firstly,secondary alkaline cooking technique was adopted to make raw sandalwood bark easy in cooking by reducing the contents of pentosan,gel and lignin.Secondly,innovative bleaching results have been achieved by using two-stage bleaching technology to make raw sandalwood pulp easy in bleaching,which not only ensure the brightness degree,but also improve the fiber strength.Raw Xuan paper made from raw sandalwood bark boasts long fiber,high fiber strength and brightness,which has reached or exceeded the national standard for Xuan paper.
