Abstract

The invention relates to a preparation process of a double-surface flat glass steel plate for laboratory test. The preparation process is characterized in that glass-fiber cloth is laid on the upper surface of a glass working platform surface; a holed pressing plate is placed on the glass-fiber cloth; a flow guiding net is put on the area with small holes; a glue filling base is put on the flow guiding net, a breathable felt is laid and covers on the glass-fiber cloth; a winding pipe is put on the glass working platform surface and is covered by the breathable felt; one end of the winding pipe is connected with an exhaust pipe, and a vacuum film is laid and covers the winding pipe, the breathable felt, the glass-fiber cloth, the holed pressing plate, the flow guiding net and the glue filling base; the edge of the vacuum film is sealed by using a sealing rubber strip and is fixed on the glass working platform surface; one end of the exhaust pipe is connected with the winding pipe, the other end of the exhaust pipe is connected with a resin collector which is connected with a vacuum pump by the exhaust pipe. Compared with the prior art, the preparation process has the advantages that the flatness of a reinforced plastic plate product is improved and the influence of the demolding cloth on the reinforced plastic plate is avoided.

Description

technical field [0001] The invention relates to a composite material vacuum infusion forming process, in particular to a preparation process of a double-sided flat glass steel sheet for laboratory testing. Background technique [0002] At present, release cloth is used in the process of preparing glass steel plates by vacuum infusion to separate the glass steel plates from the mold. The texture of the mold cloth, this product cannot meet the requirements required for laboratory testing. Contents of the invention [0003] The object of the present invention is to provide a preparation process of double-sided flat glass steel plates for laboratory testing to produce high flatness glass steel plates. [0004] Realize the technical scheme of the present invention as follows: [0005] First heat the glass worktop to between 25-35°C, [0006] Lay glass fiber cloth on the surface of the glass work table; [0007] Place a perforated plate on the glass fiber cloth; [0008] Pl...
