How is the wear resistance of polyurethane forklift wheels guaranteed by material formulation and manufacturing process?
Publish Time: 2024-12-23
Polyurethane forklift wheels are widely used in logistics, warehousing and other fields with their excellent wear resistance, high load-bearing capacity and good elasticity.
In terms of material formulation, the selection of polyurethane materials is crucial. Polyurethane is made from raw materials such as polyols and diisocyanates through chemical reactions. The types and proportions of these raw materials will directly affect the physical properties of polyurethane, including wear resistance. In order to improve wear resistance, raw materials with excellent wear resistance are usually added to the formula, such as silicone polyether polyols containing siloxane segments. This raw material can increase the contact angle of polyurethane materials to water, making them have excellent hydrophobic properties, thereby reducing the erosion of water on the material and improving wear resistance. At the same time, additives such as catalysts, chain extenders, coupling agents and cross-linking agents are also added to the formula to optimize the cross-linking structure and mechanical properties of polyurethane and further enhance wear resistance.
In terms of manufacturing process, the production process of polyurethane forklift wheels requires multiple links such as precise mold design, casting, vulcanization, and cooling. The precision and surface finish of the mold will directly affect the molding quality and wear resistance of the forklift wheels. Therefore, in the manufacturing process, high-precision molds and advanced casting technology are required to ensure that the polyurethane material can be evenly distributed in the mold to form a dense microstructure. In addition, the vulcanization process is also a key step to improve wear resistance. By reasonably controlling the vulcanization temperature and time, the polyurethane material can be fully cross-linked to form a stable network structure, thereby improving wear resistance.
In summary, the wear resistance of polyurethane forklift wheels is jointly guaranteed by scientific material formula and advanced manufacturing technology. By optimizing the types and proportions of raw materials, using high-precision molds and advanced casting technology, and reasonably controlling the vulcanization process, the wear resistance of polyurethane forklift wheels can be significantly improved, its service life can be extended, and the replacement frequency can be reduced, thereby bringing higher economic benefits to customers.
