Study on Method for Cooking Wheat Straw Pulp at Atmosphere by Microwave Radiation Mixed-Alkali Method

摘要

Cooking method of wheat straw pulp was investigated at ambient pressure by using microwave radiation alkali. Under the given microwave irradiation conditions, wheat straw was cooked with mixed-alkali. Single-factor and orthogonal experiments were applied to obtain the most favorable pulping conditions: 18 % of alkali, 1/6 of solid/liquid ratio, and 45 min of microwave heating time. Paper performance tests showed equal or better results from our paper product compared with those produced by conventional methods. A consistent yield (around 60.1 %) of wheat straw pulp was observed after repeated experiments.
