2. The plate prepared by the Chinese patent CN205219895U is directly prepared by bonding metal plates such as aluminum honeycomb cores and stainless steel plates and foaming adhesive (polyurethane adhesive), the honeycomb cores are directly used for filling, the product is not easy to change under the condition of external force, the thickness of the metal plate (usually the wall thickness is about 1 mm) needs to be ensured, after the metal plate becomes thick, the metal plate needs to be sheared and pressed by professional equipment, and bending is carried out, so that the material and labor cost of the product are increased, the product unit price is high, the market occupancy is low, resources are wasted, the foaming adhesive is completely cured for a long time (usually one week), although the surface of the adhesive is cured for only four hours, the risk of degumming is easily caused by the next procedure operation after the adhesive is not completely cured, the hollow phenomenon occurs once part of degumming occurs, and the post-sale engineering quantity of the product at the later stage is increased.

3. The intelligent functional plate manufactured by laminating the wooden splints on the two sides of the wooden keel or the light steel keel has the defects of the wooden splints, pipelines are embedded in the middle of the wooden splints, and serious fire safety hidden dangers exist.

4. Most of hot melt adhesive films in the current market have good adhesive properties for metal aluminum plates, galvanized plates, pvc foam plates and aluminum honeycomb cores, such as the hot melt adhesive films of Chinese patent CN112877019B and Chinese patent CN109796912A, and the special metal properties of stainless steel plates, and most of the hot melt adhesive films in the current market are adhered by using foamed adhesive (polyurethane adhesive), such as Chinese patent CN205219895U.
