AI Technical Summary

Technical Problem

Containers made of HDPE material have poor heat resistance and are not suitable for storing high-temperature liquids for a long time. In addition, their high hardness can easily cause the bottom of the container to crack, which limits their use in specific application scenarios.

Method used

PERT material is used to replace HDPE, and glass fiber is added during the winding process. Combined with an anti-corrosion coating layer, the heat resistance, flexibility and mechanical strength of the container are enhanced.

Benefits of technology

PERT material has excellent high-temperature resistance and flexibility. The addition of glass fiber improves mechanical strength, ensuring that the container can be used stably in high-temperature environments and is not easy to break. The anti-corrosion coating layer enhances the anti-corrosion effect, making it suitable for storing high-temperature liquids and high-density liquids.

Abstract

This utility model belongs to the field of anti-corrosion container technology, and particularly relates to a wound anti-corrosion container, including a shell, an anti-corrosion structure installed inside the shell, a material inlet / outlet structure installed at the top and middle of the bottom surface of the shell, and a stable support structure installed at the bottom of the shell. The anti-corrosion structure includes an anti-corrosion material layer, with fiberglass filaments installed on the outer surface of the anti-corrosion material layer and an anti-corrosion coating layer installed on the inner wall of the anti-corrosion material layer. The anti-corrosion material layer is made of PERT material. This wound anti-corrosion container, through the design of the anti-corrosion structure and the use of PERT material in the anti-corrosion material layer, ensures better temperature resistance and better flexibility. The addition of fiberglass filaments improves the mechanical strength of the container, making it more robust and durable. The stable support structure, with the threaded connection between the adjusting rod and the support legs, facilitates leveling of the container when facing uneven ground, thereby effectively improving the safety of the container during use.
