Beschreibung
Zusammenfassung:	A polyimide-phosphogypsum color steel sandwich panel is composed of a first protective layer, a first steel layer, a polyimide heat preservation layer, an isolation layer, a phosphogypsum heat preservation layer, a second steel layer and a second protective layer. A polyimide foam material is used as a heat preservation and insulation layer material, phosphogypsum is used as a supplementary heat insulation layer, the two layers are separated through the isolation layer, the first steel layer and the first protective layer are arranged on the other side of the polyimide heat preservation layer,and the second steel layer and the second protective layer are arranged on the outer side of the phosphogypsum heat preservation layer. All the layers are connected through adhesives, rivet and boltconnecting pieces and the like. Polyimide and phosphogypsum are adopted as heat insulation core materials, the fireproof safety performance is improved while the heat preservation and insulation effect is guaranteed, and meanw
