| titleOfInvention | Promote method and bleached chemi-mechanical pulp that bleached chemi-mechanical pulp looks whiteness |
| abstract | A kind ofly promote the method that bleached chemi-mechanical pulp looks whiteness, the method is included in the bleaching process of slurry line, in bleaching in the process of pulping, or in pulping tower, adding the step of water miscible dyestuff of 5-120ppm, this dyestuff is the mixture of the mixture of aubergine dyestuff, blue dyes, cudbear, blue-violet dyes, orchil, cudbear and orchil, aubergine dyestuff and orchil, aubergine dyestuff and the mixture of blue-violet dyes or the mixture of cudbear and blue dyes.The present invention, by adding dyestuff in bleached chemi-mechanical pulp, not only can reduce yellow hue value, also can increase the a* value of slurry, reduces b* value, and what promote pulping looks whiteness, also can reduce the addition of bleaching chemical in slurry in addition, thus effectively reduce costs.Present invention also offers bleached chemi-mechanical pulp obtained by said method. |
