The application discloses a self-adaptive GRG artistic modeling ceiling assembly structure and particularly relates to the technical field of house decoration, which comprises a GRG panel body, a keel frame, a self-adaptive assembly, a buffer assembly and a connecting assembly. The keel frame is detachably connected with a wall body through bolts, and the self-adaptive assembly is arranged on the keel frame. The buffer assembly is arranged in the self-adaptive assembly. The GRG panel body is connected with the self-adaptive assembly through the connecting assembly. The application has a reasonable structure design, can quickly fix the GRG panel, can self-adaptively adjust the installation of a curved ceiling, can improve the installation and adjustment capacity and efficiency of the GRG artistic modeling ceiling, can reduce the difficulty of fixing between two adjacent GRG panels, and can improve the installation stability of the GRG panel.

The invention relates to the technical field of PVC material preparation, in particular to a slush molding PVC skin preparation process based on a modified PVC material, which comprises the following steps: heating a slush molding mold, conveying a material box containing PVC slush molding powder to the lower part of the slush molding mold, and connecting and coupling the material box and the slush molding mold; turning over the coupled material box and slush molding mold for a plurality of times, separating the material box from the slush molding mold after the redundant PVC slush molding powder falls into the material box, cooling the slush molding mold, and demolding to output a finished product slush molding skin; determining the interval duration between the heating moment and the cooling moment based on the average roughness of the sampling area in the finished product slush molding skin; the first overturning speed of the slush molding mold is determined based on the proportion of the number of defective products in the slush molding skin of the finished product; and the second overturning speed is determined based on the maximum thickness difference quantity of the finished product slush molding skin. According to the invention, the preparation accuracy of the PVC material is improved.
