Problems solved by technology

However, due to the influence of the following factors, it is difficult to ensure that the gas in the gap is completely removed by this method
Since the vacuuming operation is only to deal with the residual air in the gap between the marbles, the requirements for the vacuum degree are relatively low. The claims of the invention application require -0.08MPA~0.098MPA, but such a vacuum value is difficult to remove the air in the glue The gas is excluded, and due to the irregular shape and inconsistent depth of the marble gap, new gas is often generated when injecting glue into the gap, so it is difficult to ensure that the final product will not be deformed or twisted

Embodiment Construction

[0011] Use a high-pressure water gun to clean and dry the surface of the marble and the interior of the cracks; prepare a vacuum box, and install two sets of 5.5KW rotary vane vacuum pumps on the vacuum box; inject glue into the cracks on the marble surface; put the glued marble into the vacuum Vacuumize the inside of the box to extract the air from the cracks of the marble and the glue layer, so that the glue layer can be further compressed and infiltrated; the pressure in the vacuum box is kept between -0.1MPA and 0.15MPA; the marble is taken out and injected again into the cracks Glue and repeat step 4 until the glue layer no longer sags and infiltrates; grind and polish the glued marble.

Abstract

The invention relates to a vacuum glue-replenishing method for marble, which comprises the following steps: cleaning the marble surface and the interiors of cracks and drying; preparing a vacuum tank and mounting two sets of 5.5kW rotary-vane vacuum pumps on the vacuum tank; injecting glues on the surface and cracks of the marble; placing the marble injected with the glues into the vacuum tank for performing vacuum pumping treatment; extracting air from the cracks and glue layers of the marble, thereby causing the glue layers to be further compressed and permeated; keeping a pressure value in the vacuum tank within a scope from -0.1MPa to 0.15 MPa; taking the marble out, injecting the glues to the cracks again and repeating the vacuum pumping treatment till the glue layers no longer sink and permeate; and grinding and polishing the glue-replenished marble. The vacuum glue-replenishing method is simple in technology. The waste phenomenon caused by using the marble as a building material is effectively eliminated.

Description

technical field [0001] The present invention relates to the technical field of marble processing, and in particular relates to a marble vacuum glue repair method. Background technique [0002] Invention patent application specification with application number 200810038755.5 discloses a block vacuum glue filling process, which is closest to the content of the present invention and can be used as a reference document of the present invention. In the method, the stone blocks are placed in a vacuum device, and glue is injected into the gaps of the blocks under a vacuum environment. However, due to the influence of the following factors, it is difficult to ensure that the gas in the gap is completely removed by this method. Since the vacuuming operation is only to deal with the residual air in the gap between the marbles, the requirements for the vacuum degree are relatively low. The claims of the invention application require -0.08MPA~0.098MPA, but such a vacuum value is diffic...
