| titleOfInvention | The wet strong waste paper recycling pulping process of a kind of pair of pH value |
| abstract | The invention discloses the wet strong waste paper recycling pulping process of a kind of pair of pH value, this method includes material papering section, decatize workshop section, the first extrusion impregnating chemical mechanical processing section, the second extrusion impregnating chemical mechanical processing section, disappears latent and discongest section and purification screening enriching section again.The present invention is acted on while not reducing former pulp strength by mechanical forceful action and chemical treatment, realizes wet strong waste paper fibre dissociation repulping；Further can be in the two sections of extrusion impregnating connected chemical mechanical processing sections, wet strength agent first in acid condition in oxidation waste paper, then hydrolysis is further promoted in the basic conditions, more effectively destruction wet strength agent is intermolecular and chemical bond between wet strength agent and paper pulp fiber, effectively increases fiber dissociation yield and repulping yield.Solve wet strong waste paper and reclaim the problem of slurrying rate of dissociation is low, intensity declines to a great extent, and continuous, scale, low water consumption, the pollution-free environment-friendly pulping of low energy consumption can be realized. |
