预水解玉米秸秆基质化学热磨机械浆配抄瓦楞原纸研究
Research on the Preparation of Corrugated Board Paper by Blended Papermaking with Chemi-thermomechanical Pulping of Pre-hydrolyzed Corn Straw Substrate
摘要
Abstract
This study used pre-hydrolyzed corn stover-based chemi-thermomechanical pulp(C-CTMP)and old corrugated container(OCC)pulp as raw materials,aiming to enhance the properties of corrugated paper by optimizing refining,blending,and sizing processes.The results showed that after C-CTMP was refined with 5 000 r in a PFI mill(reaching a freeness of 45 °SR),the paper achieved optimal mechanical properties,in-cluding a breaking length of 5.64 km,burst index of 2.60 kPa·m2/g,tear index of 5.40 mN·m2/g,and ring crush index of 8.74 N·m/g.When C-CTMP mass ratio was 40%,the produced corrugated paper exhibited a density of 0.62 g/cm3,breaking length of 4.25 km,and ring crush index of 8.24 N·m/g,all demonstrating favorable mechanical performance.Furthermore,with the addition of 0.25%alkyl ketene dimer(AKD)and 1%dry cationic starch(both based on oven-dry pulp mass),the corrugated paper achieved a density of 0.60 g/cm3,breaking length of 4.56 km,ring crush index of 8.62 N·m/g,and water absorption Cobb60 value of 13.00 g/m2,meeting the requirements for Grade AAA premium products under GB/T 13023-2008.关键词
