Study on Preparation and Strength Properties of Corrugated Medium Using Bamboo Pulp and Camphor Residue Pulp
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,concen-tration 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.
