| abstract |
The invention discloses a kind of method using sulphite production high transparency paper, including according to parts by weight, 5 parts of hemicellulase, 3 parts of cellulase, 3 parts of zytase and 2 parts of pectase weigh each component by above-mentioned formula；The present invention is penetrated into clarifier and drives air inside paper away, due to clarifier index of refraction close to cellulose fibre index of refraction, it is crosslinked to improve paper transparency while enter after interfibrous transparency agent solidifies with fiber so just will form uniform optical property, moreover it is possible to improve paper strength.Internal addition method is that clarifier and slurry are beaten together, and when admixture sufficiently adsorbs on cellulose, after being copied into paper web drying, paper transparency can reach prescribed requirement. |
