Problems solved by technology

[0003] As a fast-growing and high-yielding plant, bamboo fiber not only has a high survival rate and a short growth period, but also has strong wear resistance and moisture absorption, which is stronger than cotton fiber and viscose fiber, and has broad application prospects. Or renewable resources have super hygroscopicity in an instant, which also requires higher requirements for their water resistance to a certain extent
On the other hand, in order to improve the water repellency and oil repellency of existing pulp molded products, corresponding water repellent and oil repellant are added, and the above-mentioned products are in the process of natural degradation, because the characteristics of water repellent are weak. Cationic, when it is added to the pulp, it will adhere to the surface of the fiber due to electrostatic adsorption, forming a film on the surface of the fiber, making the connection between the fiber and the fiber tighter, and inhibiting the breakage of the cellulose macromolecular chain to a certain extent. Therefore, as the amount of waterproofing agent is imposed, its tensile strength increases, its quality declines slowly in the natural environment, and the weight loss rate decreases.
Sugarcane is a stem-shaped plant fiber raw material that grows throughout the year. Its fiber structure includes crystalline regions and non-crystalline regions. However, the molded products made of sugarcane in the prior art are rough and difficult to degrade

Abstract

The invention discloses a process for preparing a paper-plastic molded high-quality yellow serofluid product. The process comprises the following steps: soaking raw bamboos and raw sugarcanes, and carrying out pulping and grinding treatment so as to obtain sugarcane fibers, respectively selecting bamboo fibers and sugarcane fibers of 200-400 meshes, adding water, and carrying out stirring so as toobtain a slurry; and adding an adhesive, sodium alginate, chitosan, a waterproof agent and an anionic emulsifier into the prepared slurry, carrying out uniform mixing, feeding an obtained mixture into a molding machine, carrying out dehydrating and hot press molding. Meanwhile, the invention also discloses equipment for preparing the paper-plastic molded high-quality yellow serofluid product. Theyellow serofluid product prepared through the process and the equipment provided by the invention is environmentally friendly, easy to be degraded and high in tensile strength; meanwhile, a product prepared through the equipment does not retract.

Description

technical field [0001] The invention relates to the field of pulp molding, in particular to an equipment and a process for preparing fine-quality yellow pulp products formed by paper molding. Background technique [0002] In recent years, with the increasing demand for manufacturing products, especially for outer packaging manufacturing products, the immature manufacturing process has also brought corresponding environmental problems, and people's growing awareness of environmental protection has made technicians In-depth research on the manufacture of renewable resources. The pulp of current pulp molding products is mainly divided into two types, one is yellow pulp, which has lower cost and lower product requirements, and is mainly used in the domestic low-end fast-selling product market, such as packaging trays for eggs, shoes, red wine, etc.; White pulp is mainly used in the high-end international electronic consumer market, such as packaging for iPhones and pads, which ...
