Generally speaking, the service life of the sandwich panel is analyzed on the basis of the coating structure characteristics of the sandwich panel and its mechanism, which means its corrosion resistance and the weather resistance of the organic coating film under actual application conditions. The unified embodiment of the effective use limit of the two performances. The measurement standards of service limit are not uniform, and the concept of service life cannot be consistent.
1. Thermal insulation: thermal conductivity of core material: λ<=0.041w/mk;
2. Light weight: 10-14 kg/m2, equivalent to 1/30 of a brick wall;
3. Oxygen Index: (OI) 32.0 (Provincial Fire Products Quality Inspection Station);
4. Flexible and quick installation: the construction period can be shortened by more than 40%;
5. Bright color: no surface decoration is required, and the anti-corrosion layer of the color galvanized steel plate can be kept for 10-15 years;
6. High strength: The sandwich panel can be used as a ceiling panel for load-bearing, bending and compression resistance.
