Publish Time: 2024-11-26
Cross-linked irradiated PE line, as a high-performance wire material, has attracted much attention in the wire and cable industry in recent years. This wire uses high-energy radiation to induce chemical bonding between polymer molecular chains, that is, cross-linking reaction, which significantly improves its mechanical strength and wear resistance.In terms of mechanical strength, cross-linked irradiated PE line performs well. Due to the irradiation cross-linking process, the molecular chain structure of PE material has changed, forming a tighter three-dimensional network structure. This structural change enables the material to better disperse stress when subjected to external force, thereby improving the tensile strength and tear resistance of the material. Therefore, cross-linked irradiated PE line shows higher stability and durability when subjected to mechanical stress.In addition to mechanical strength, cross-linked irradiated PE line also has excellent wear resistance. Wear resistance refers to the ability of a material to resist wear during friction. Due to the cross-linking effect between molecular chains, the surface hardness of cross-linked irradiated PE line increases, reducing the amount of wear during friction. At the same time, cross-linked irradiation can also improve the heat resistance and chemical corrosion resistance of PE materials, and the improvement of these properties further enhances its wear resistance.In practical applications, these performance advantages of cross-linked irradiated PE line have been fully reflected. For example, in occasions where large mechanical stress and friction wear are required, such as internal connecting wires of mechanical equipment, automotive wires, etc., cross-linked irradiated PE line can maintain stable performance for a long time and extend its service life.In addition, the production process of cross-linked irradiated PE line also has certain advantages. Irradiation cross-linking is a physical modification method that does not require the addition of chemical cross-linking agents, so high-purity cross-linked products can be obtained. This not only improves the performance of the product, but also reduces production costs and environmental pollution.In summary, cross-linked irradiated PE line has significant advantages in mechanical strength and wear resistance, and is a high-performance material in the wire and cable industry. With the continuous advancement of technology and the continuous expansion of applications, cross-linked irradiated PE line is expected to play an important role in more fields.
