Method for selecting red sand stone

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 genetic engineering, in particular to the application and screening method of EPAS1 gene tag single nucleotide in screening people adapted to plateau environment. Background technique [0002] my country is a mountainous plateau country, and the plateau area above 3,000 meters accounts for 1 / 4 of my country's land area, which is the main direction and main battlefield of the western development. Among them, the Qinghai-Tibet Plateau is the most important area, which is rich in resources (minerals, petroleum, water conservancy, tourism, etc.) and needs to be developed urgently. At the same time, the Qinghai-Tibet Plateau is also an important national defense and military support area in my country. [0003] However, for people who are new to the plateau, high altitude hypoxia can cause altitude sickness. Common symptoms include headache, insomnia, loss of appetite, fatigue and dyspnea. Generally speaking...

AI Technical Summary

Problems solved by technology

Therefore, the harm of plateau hypoxia to the human body has greatly affected the construction, development and stability of the plateau. Therefore, it is especially important to prevent and reduce acute altitude sickness and maintain human health. However, there is currently no way to predict the population that may experience altitude sickness
