Embodiment 1

[0026] A method for selecting red sandstone, specifically comprising the following steps:

[0027] (1) Red sandstone is carried out preliminary screening classification, selects the red sandstone solid mineral of suitable size, for subsequent use;

[0028] (2) the red sandstone solid mineral screened out in the step (1) is carried out strong magnetic desliming under the magnetic field strength of 0.8T, cleans up, for subsequent use;

[0029] (3) Fluosilicic acid, magnesium sulfate, lightly burned powder and water are prepared into a soaking solution according to the mass ratio of 1:0.5:1:70, and the red sandstone treated in step (2) is soaked in the soaking solution , pick up and drain the surface water, then soak twice, soak for 10 minutes each time, dry at 50°C for 30 minutes, and set aside;

[0030] (4) After the red sandstone in step (3) is dried, spray the vegetable dye evenly until saturated, wait until the plant dye is absorbed by the red sandstone, continue to spray t...

Abstract

The invention relates to the technical field of rock body selection, and in particular relates to a method for selecting a red sand stone, and the method comprises the following steps: 1) primarily screening and grading the red sand stone; 2) performing strong magnetic deliming and cleaning; 3) dissolving fluorosilicic acid, magnesium sulfate and light burning powder in water to prepare a soakingliquid, soaking the red sand stone in the soaking liquid, and then drying the red sand stone after picking up; 4) after the red sand stone is dried, spraying the red sand stone with a vegetable dye evenly until saturation, until the vegetable dye is absorbed by the red sand stone, further spraying the red sand stone with the vegetable dye for 2 to 3 times, and drying to obtain a selected red sandstone; wherein the vegetable dye is mainly prepared from safflower, rhus coriaria fruit, rose, trisiloxane polyoxyethylene ether, acetic acid and absolute ethanol. The method is simple in operation, can effectively strengthen the strength of the red sand stone, reduces the weathering erosion degree of the red sand stone, makes the red sand stone bright in color, improves the texture and visual effect of the red sand stone, thereby improving the quality and qualified utilization rate of the red sand stone.

Description

technical field [0001] The invention relates to the technical field of rock mass selection, in particular to a method for selecting red sandstone. Background technique [0002] Red sandstone is deeply loved by the public because of its bright red color, delicate and beautiful appearance, and is widely used in construction, bridges and other fields. However, red sandstone has weaknesses such as loose structure, weak weather resistance, and insufficient hard texture, making it easy to weather. , short service life and other problems, thus restricting the application field of red sandstone. Therefore, how to strengthen the red sandstone and enhance the weathering resistance has become the focus of attention. Contents of the invention [0003] The purpose of the present invention is to provide a method for selecting red sandstone in view of the above-mentioned problems. The method is simple to operate, can effectively strengthen the strength of red sandstone, reduce the degre...
