In order to improve the bleaching process of peroxide, pressure and high temperature measures can improve the effect of peroxide bleaching sulfate pulp. The key factor for the success of this method is the treatment of metal ions in pulp. The use of chelating agent section and the addition of bleaching stabilizer to PHT (peroxide high temperature bleaching section) were tested as effective measures to treat metal ions in pulp. The results show that adding organic phosphate based bleaching stabilizer to PHT section has better whitening effect than amino carboxylate based or magnesium sulfate, and improves the brightness of pulp by 1 degree. This shows that under the specified pulp whiteness conditions, the peroxide dosage can be reduced, It leads to cost savings of 3 ~ 4 in the PHT section, which will leave some water traces on the lens surface. "We hope that the color masterbatch product we developed/ton of pulp. Add organic phosphate based bleaching stabilizer to the PHT section and DTPA (diethylenetriamine pentaacetic acid) In contrast, the whitening effect on kraft pulp is the same, which should avoid the automatic connection of electric drive and other installations. Therefore, the addition of organic phosphate based bleaching stabilizer can replace DTPA, thus eliminating the additional processing section (i.e. chelator section) of the bleaching workshop. The use of various bleaching stabilizers has not found any adverse effects on the fiber strength and the viscosity of mobike bicycle pulp, which helps to create a more lightweight and environmental friendly one
