english How to improve the wear resistance of polyethylene packaging material
2025-04-16
The following are some methods to improve the wear resistance of polyethylene packaging material:
1. Adding wear-resistant fillers
Adding an appropriate amount of wear-resistant fillers to polyethylene is an effective way to improve its wear resistance. For example, adding inorganic fillers such as silica and alumina, which have high hardness and wear resistance, can be evenly dispersed in the polyethylene matrix to play a reinforcing role. When the material surface is rubbed, the filler can bear part of the friction and reduce the wear of the polyethylene matrix.
2. Surface treatment
Surface treatment of polyethylene packaging material can improve its surface properties and wear resistance. Common surface treatment methods include plasma treatment and ultraviolet radiation treatment. Plasma treatment can introduce some polar groups on the polyethylene surface, increase the surface roughness and hardness, and thus improve its wear resistance. Ultraviolet radiation treatment can cause cross-linking reaction on the polyethylene surface to form a cross-linked layer with high hardness and wear resistance.
3. Optimize processing technology
By optimizing the processing technology, the molecular chain arrangement of polyethylene packaging material can be made more regular, the crystallinity can be improved, and the wear resistance of the material can be improved. In addition, the use of stretching technology to treat polyethylene film can also orient the molecular chain along the stretching direction, thereby improving the strength and wear resistance of the film.
4. Blending modification
Blending polyethylene with other polymers with good wear resistance is also a way to improve its wear resistance. For example, blending polyethylene with polypropylene, polyamide, etc. can combine the advantages of each component to improve the wear resistance, strength and toughness of the material. At the same time, adding an appropriate amount of compatibilizer during the blending process can improve the compatibility between different polymers and make the blend have better performance.
