Research of Dual Cooking Reagents on Bamboo Pulping

Bamboo, as a kind of non-wood raw material, has a long, thin fiber with wide distribution and rich abundance in China. It was studied that cooking reagents on bamboo pulping. AQ ramification and infiltration reagents were used to improve the cooking schedule. The results showed that AQ ramification could strengthen the cooking, but infiltration reagents couldn't reach the good expect in cooking. When the AQ ramification and infiltration reagents were used together to cook, it could obviously decrease the Kappa number of the pulps and enhance the yield of pulps. Infiltration reagent Busperse 2806 was the best choice in cooking with AQ ramification. When the dosage of AQ ramification 0.05%, Infiltration reagent 0.03%, the yield of pulps increased 1.31%, kappa number decreased 4.0, and the dosage of AQ ramification 0.05%, Infiltration reagent 0.03%, the kappa number decreased 5.5, the screened yield decreased 1.54%.
