Study on the DDS Cooking of Bamboo (Neosinocalamus)
摘要
Abstract
The effects of NaOH dosage on the IC,IMC and MFC stage of DDS cooking of bamboo (Neosinocalamus) were studied in this paper. With NaOH dosage increasing,cooking reagent could penetrate to inner of the bamboo quickly in preimpregnating stage,which could be beneficial to cooking. IMC was better to delignification on cooking than IC,and MFC was the most significant influence on the depth of delig-nification. It was good for the extended delignification when the sulfidity increased from 23% to 44% ,and the Kappa number and the yield decreased. Under the pulping condition of 10 g/L in IC stage,15 ~20 g/L in IMC stage and 30 g/L in MFC stage of the NaOH dosage,and with the sulfidity of 23% -30% ,the Kappa number was 10. 7 - 17.8,and yielding was 43. 1% -45.1%. The pulp of DDS cooking of bamboo,which would be lower kappa number and higher yield,has advantage in pulping qualitatively than common cooking pulp.关键词
