Improving the strength and durability of pulp molded plant fiber tableware is a complex problem involving many aspects, which needs to comprehensively consider multiple factors such as raw material selection, structural design, processing technology, and post-processing. Here are some ways that may help improve the strength and durability of pulp molded plant fiber tableware:
1.Raw material selection: Choosing plant fibers with long fiber length and strong inter-fiber adhesion as raw materials can improve the strength and durability of tableware. At the same time, an appropriate amount of fillers or reinforcing agents, such as starch, dextrin, silicate, etc., can be added to further improve the physical properties of the tableware.
2.Structural design: Reasonable structural design can make the tableware have a certain tensile capacity and bending stiffness, so that it is not easy to deform or crack when subjected to external forces. The structural stability of tableware can be improved by optimizing the mold design and adding stiffeners.
3.Processing technology: Proper processing technology can affect the arrangement and combination of plant fibers in the mold, which can affect the strength and durability of the tableware. By optimizing the process parameters such as grouting, demoulding, and drying, the plant fibers can be fully expanded in the mold and form a stable bonding structure.
4.Post-treatment: Post-treatment can further strengthen and protect pulp molded plant fiber tableware, improving its durability and waterproofness. Coating, hot pressing, impregnation and other methods can be used to form a protective film on the surface of the tableware to prevent the penetration and erosion of moisture and grease.
5.Storage and use conditions: The strength and durability of pulp molded plant fiber tableware are also affected by storage and use conditions. Tableware should be avoided from being exposed to high temperature and high humidity for a long time to prevent moisture deformation or mold. At the same time, the impact or scratch caused by external force on the tableware should be avoided during use, so as to prolong its service life.
In summary, improving the strength and durability of pulp molded plant fiber tableware requires a combination of factors and a variety of methods to work synergistically. Through reasonable raw material selection, structural design, processing technology, post-processing and correct storage and use conditions, the physical properties and service life of tableware can be effectively improved.
