Efficient insulation board

1. One is to use polystyrene sandwich panels as insulation panels for thermal storage; Another method is to use polyurethane sandwich panels as insulation boards, with stainless steel panels or plastic steel plates attached on both sides. Polystyrene sandwich panels have a high thermal conductivity and slightly inferior insulation performance compared to the latter, but they are still relatively reliable for use in medium to high temperature active cold storage and have a moderate price. Polyurethane foam materials have low thermal conductivity, good insulation performance, and can save energy to prolong the service life of compressor units. They are often used in low-temperature active cold storage.

2. The sealing material for the activity cold storage panel is generally made of sealant combined with special aluminum alloy.
