Definitions

  • the invention relates to a pulp and a manufacturing method thereof, in particular to a pulp prepared by using water sponge and a manufacturing method thereof, and belongs to the technical field of papermaking.
  • Pulp is processed from certain plants and is the basic raw material for papermaking. Plants commonly used for pulping materials can be classified into four broad categories: stem fibers, bast fibers, hair fibers, and wood fibers. Among them, wood fiber is the most important. At present, China's timber resources are far from meeting the needs of the growing pulp and paper industry. Of course, this is also a worldwide problem. In addition, in the pulp manufacturing process, whether using wood fiber or herb fiber, a large amount of chemicals are used, a large amount of water is needed, and a large amount of energy is consumed, and a large amount of toxic and harmful substances and sewage are generated. The environment caused serious damage.

  • the proportion of photosynthetic pigments is similar to that of seed plants and other higher plants.
  • Typical green algae cells may or may not be active. It has a central vacuole, and the pigment is in the plastid, and the shape of the plastid varies depending on the type.
  • the cell wall consists of two layers of cellulose and pectin.
  • the food is stored in the form of starch in the nucleus of the plastid.
  • Chlorella grows in fresh water, often attached to submerged rocks and wood, or floats on the surface of stagnant water; there are also species that live in soil or seawater, which is the source of aquatic animals' food or oxygen.
  • Spirogyra belongs to the genus Chlorophyta, the genus Algae, the genus Spirogyma, and the genus Spirogyra.
  • the algal body is an unbranched filamentous body formed by a column of cylindrical cells. Since the surface of the algae has more pectin, it is sticky and slippery when touched by hand. Under the microscope, it can be seen that there are one or more banded leaf margins in each cell, which are spirally wound around the cytoplasm in the cell wall, and have a column of protein nuclei on the chloroplast. There is a large vacuole in the center of the cell. One cell nucleus is located in a mass of cytoplasm in the center of the vacuole. There are a number of radial cytoplasmic filaments connected between the cytoplasm surrounding the nucleus and the cytoplasm surrounding the cell wall.
  • the invention relates to the use of cotton wool grown in fresh water as a raw material for making pulp.

Abstract

L'invention concerne une pâte constituée de Spirogyra et son procédé de préparation, qui appartiennent au domaine technique de la fabrication du papier. Concernant le procédé, Spirogyra est utilisée comme matière première et une pâte est obtenue par les procédés de travail consistant à broyer, à blanchir, à raffiner en pile, à laver, etc. Grâce au procédé, les ressources ligneuses sont fortement économisées et les ressources de la forêt sont protégées. La matière première utilisée, Spirogyra, vit principalement dans l'eau douce, et la croissance même de Spirogyra peut avoir pour effet de purifier la qualité de l'eau et d'embellir l'environnement. Étant donné que pendant le procédé de fabrication de la pâte il n'y a pas de procédé de travail de cuisson et qu'un procédé de travail de lavage est évité, l'énergie est économisée, l'utilisation d'un grand nombre de réactifs est réduite, les ressources précieuses en eau sont économisées, et en même temps la production d'eaux usées est éradiquée et la contamination de l'environnement est efficacement empêchée.
