AI Technical Summary
Existing elevator wire rope core materials suffer from insufficient toughness and lubrication during use, making it difficult to meet the wear resistance and tensile strength requirements for long-term use. Furthermore, the recycling rate of polyethylene waste is low, which affects environmental protection.
The core material of the steel wire rope is made of recycled fibers made of modified recycled high-density polyethylene and carbon fiber. The material properties are improved by grafting with butyl acrylate and treating with concentrated nitric acid. It is then combined with sisal fibers and galvanized steel wire to form a composite core. An elastic buffer and wear-resistant protective layer are added to improve the overall performance of the steel wire rope.
It improves the tensile strength and flexibility of steel wire rope, enhances oil storage capacity, extends service life, and enables the recycling of polyethylene waste, thus promoting environmental protection.
