白构皮制备纸浆的方法
摘要：
一种白构皮制备纸浆的方法，首先将去除黑皮的白构皮切成小段，待用；取切片筛选后的白构皮置于水中，然后再加入NaC2O4，萃取白构皮中的果胶；萃取完成后，采用机械疏解将萃取果胶后的白构皮进行纤维分散，然后将纤维和溶液分离；将分离后的纤维配制成纸浆，然后加入H2SO4预处理；在预处理后的纸浆中加入Mg2SO4、Na2SiO3、NaOH和H2O2进行漂白；在漂白后的纸浆中加入Mg2SO4，Na2SiO3，NaOH和H2O2再次漂白即可。本发明先对白构皮中果胶进行提取，再对提取果胶后的白构皮进行机械处理，使其成浆，对纸浆后续漂白采用过氧化氢再加过氧化氢两段漂白，不但能得到高得率的白构皮浆，而且能得到附加高的果胶。
摘要（英）：

The invention relates to a method for producing paper stuff with white paper. First, white paper after removing black paper is cut into small segment for standby application and screening white paper is set in water with NAaC204 so as to extract pectin in white paper. After extracting white paper without pectin is decomposed to fibre in mechanical method and fibre is dissociated from liquor. Detached fibre is prepared for paper stuff which is treated in prior with H2SO4. Paper stuff with Mg2SO4, Na2Sio3, NaOH and H202 after pretreatment is whitened, then Paper stuff with Mg2SO4, Na2Sio3, NaOH and H202 after bleaching is whitened again. Through extracting pectin from white paper, handling white paper without pectin in mechanical method, making it slurry, whitening paper stuff by H202 two times, there are not only gaining white paper stuff in high production ratio but also additive high pectin.
