Diethanolamine Pulping Process of Pinus Kesiya

Abstract:

In this paper, under the premise of maximum temperature not more than 200 °C, the diethanolamine pulping process of pinus kesiya was optimized. AQ was used as the additive for pulping. Under the optimum pulping condition, the pulp properties were as follows: screened pulp yield 61.9%, viscosity 1306mL•g^-1 and kappa number 24.3. The handsheets physical properties were as follows: tensile index 77.6N•m•g^-1, bursting index 6.40kPa•m²•g^-1, tearing index 10.63mN•m²•g^-1
