Problems solved by technology

However, in the conventional press molding process, since the plastic film or kraft paper is too soft, and the kraft paper absorbs water and is easy to wrinkle during the pressing process, the wrinkled paper is easy to fall into the ecological stone material under a large pressing pressure, and the use of plastic film or kraft paper Increase the thickness and grinding amount of the ecological stone products in the later stage, making the ecological stone products prone to cracks, and the quality is seriously affected

Abstract

The invention relates to the technical field of ecological stone production, in particular to an ecological stone pressing process. The process comprises A, arranging ecological stone slurry in a dieframe, and carrying out bottom face high-frequency vibration on the die frame with the slurry, B, covering the upper surface of the die frame, on which the slurry is distributed, with a rubber plate,C, carrying out flexible pressing under vacuumizing, and D, removing the rubber plate to expose the upper surface of the ecological stone formed body, and sending the ecological stone formed body to asubsequent section. The process is simple, overflowing is avoided during pressing, a plastic film or kraft paper is prevented from being used, the process is environmentally friendly, follow-up maintenance is conducted after a rubber plate is torn off, and the prepared ecological stone product is compact, few in air hole, free of crack defects and small in fixed thickness and grinding amount.

Description

technical field [0001] The invention relates to the technical field of ecological stone production, in particular to an ecological stone pressing process. Background technique [0002] With the development of modern construction, consumers have put forward requirements for light weight, high strength, beautiful appearance and variety of decorative materials. Ecological stone, which is more in line with the demands of circular economy and energy saving and environmental protection, has gradually become the mainstream trend of product development in the stone industry. Ecological stone products are also developing from a single traditional product to a multi-function and multi-purpose demand. The ecological stone is generally solidified after vacuum pressing. Before pressing, it is necessary to spread plastic film, kraft paper and other materials on the surface of the mold to isolate the ecological stone material from the surface of the mold so as to facilitate demoulding. Ho...
