| 摘要:本研究对市售本色竹浆进行筛分,利用筛分出的粒径<0.6 mm的短小纤维竹浆与蒸油后的油樟渣浆配抄瓦楞原纸。结果表明,抄纸中加入25%针叶木浆、0.5%阳离子淀粉(CS)、0.4%阳离子聚丙烯酰氨(CPAM)和1.8%聚酰胺环氧氯丙烷树脂(PAE,质量分数9.5%),短小纤维竹浆(未打浆)与油樟渣浆按质量比10∶90配抄,未经熟化处理的纸张裂断长2.66 km,环压指数5.60 N·m/g,达到了瓦楞原纸GB/T 13023—2008合格品要求;当短小纤维竹浆打浆度35.8 °SR时,与油樟渣浆按照质量比30∶70配抄,并经110 ℃、15 min熟化处理,纸张裂断长4.75 km、环压指数8.24 N·m/g、耐破指数2.80 kPa·m2/g、耐折度15次,其中裂断长和环压指数均达到瓦楞原纸GB/T 13023—2008优等品要求,耐破指数和耐折度指标均达箱纸板GB/T 13024—2016合格品要求。 |
| Abstract:In this study, the commercially available natural bamboo pulp was sieved, the short-fibre bamboo pulp with partide size<0.6 mm and oil evaporation of camphor residue pulp were selected to prepare corrugated medium. The results showed that when 25% soft wood pulp, 0.5% cationic starch (CS), 0.4% cationic polyacrylamide (CPAM) ,and 1.8% polyamide epichlorol resin (PAE, concentration of 9.5%) were added, short-fibre bamboo pulp (unbeaten) and camphor residue pulp were used to prepare paper with the mass ratio of 10∶90 without cure treatmeut, the paper splitting length was 2.66 km, the cyclic compression index was 5.60 N·m/g, which met the requirements for the qualified products of GB/T 13023—2008.When the short-fibre bamboo pulp was beat to a degree of 35.8 °SR, and the camphor residue pulp was added with the mass ratio of 30∶70, after cure treatment 110 ℃ for 15 min, the paper was obtained with splitting length of 4.75 km, cyclic compression index of 8.24 N·m/g,breakage resistance index of 2.80 kPa·m2/g, folding resistance of 15, of which the splitting length and the cyclic compression index reached the requirements for the superior grade of GB/T 13023—2008 , breakage resistance index and folding resistance indicators were up to the requirements for qualified products of GB/T 13024—2016. |
