AI Technical Summary
Technical Problem
The installation process of existing rigid foam fillers for LNG membrane tanks is cumbersome, easily damages the insulation module, and uneven glue application leads to inaccurate installation, affecting system performance.
Method used
Rigid foam fillers made of polyurethane foam are cut and uniformly coated with adhesive, and then pressurized with airbags to ensure complete curing and uniform pressing of the adhesive, avoiding the use of rigid wedges.
Benefits of technology
It simplifies the installation process, improves work efficiency, ensures stable adhesion between rigid foam fillers and insulation modules, and enhances the system's sealing and thermal insulation performance.
