Description

Technical Field

[0001] The invention belongs to the technical field of thermal insulation sleeve preparation, and in particular relates to a preparation process of a graphene coating thermal insulation sleeve. Background Art

[0002] Insulation sleeves are insulating materials wrapped around pipes, containers or other equipment to prevent heat loss or gain. They are commonly used for the following purposes: 1. Prevent heat loss: When hot fluids are transported in pipes or containers, insulation sleeves help prevent heat from being lost to the surrounding environment; 2. Prevent condensation: When cold fluids are transported in pipes or containers, insulation sleeves help prevent condensation from forming, which can cause corrosion or other problems; 3. Personnel protection: Insulation sleeves can prevent personnel from contacting hot or cold surfaces; 4. Energy saving: By preventing heat loss, insulation sleeves can help reduce energy consumption.

[0003] Graphene coating has excellent thermal insulation effect, and its thermal conductivity is usually less than 0.01W / mK, which makes it effective in blocking heat transfer and thus improving the thermal insulation performance of the coated object. Graphene coating can be used in buildings, pipelines, containers and other occasions that require thermal insulation.

[0004] The insulation sleeve in the prior art can be used for heat preservation, but the insulation effect is not ideal. The poor insulation effect of the insulation sleeve can easily cause heat to escape or enter from the pipe, container or other equipment, thereby reducing energy efficiency and increasing costs. In addition, the existing protective sleeve has poor wear resistance and anti-aging effects, short service life, and is prone to damage. To this end, we provide a graphene coated insulation sleeve preparation process to solve the above problems. Summary of the invention

[0014] S5. Final forming: Finally, use the installation tool to install the insulation sleeve on the surface of the pipeline to be constructed.

In addition, the double-layer composite outer layer design increases the service life while ensuring the thermal insulation effect, making it more practical.
