| titleOfInvention | Method for preparing primary-color biomechanical pulp by treating wheat straws with hot steam and biological enzyme |
| abstract | The invention relates to a method for preparing primary-color biomechanical pulp by treating wheat straw with hot steam and biological enzyme, which comprises the steps of treating wheat straw with hot steam and water vapor, adjusting the pH value of hot water to 10-14 by adding trace alkali, softening wheat straw by steaming and water thermal saturation after partial hemicellulose, lignin, pectin and other substances are dissolved out of the wheat straw, carrying out spiral extrusion treatment to physically divide the wheat straw into filaments, carrying out biological enzyme treatment, further softening fibers, and pulping the wheat straw to meet the requirements for producing primary-color packaging paper and paper-based materials. |
