preparation example Construction

[0042] Correspondingly, the embodiment of the present invention also provides a simple and low-cost preparation method of the above-mentioned water-retaining and sand-fixing material. This preparation method comprises the steps:

[0043] S01. Weigh each component respectively according to the above-mentioned water-retaining and sand-fixing material;

[0044] S02. Mix the weighed components according to their proportions, and sieve them.

[0045] Specifically, in the above step S01, the types and amounts of the components of the water-retaining and sand-fixing material are the same as those described above for the water-retaining and sand-fixing material, and will not be repeated here to save space.

[0046] The mixing process in the above step S02 can be directly performed by stirring and mixing, and of course other mixing processes can also be used, as long as the purpose of uniform dispersion of each component can be achieved, which is within the scope of the disclosure of ...

Embodiment 1

[0058] Example 1 provides a water-retaining and sand-fixing material and a preparation method thereof. The water-retaining and sand-fixing material comprises the following components by mass:

Abstract

The present invention discloses a water-retention sand-fixing material and a preparation method and application thereof. The water-retention sand-fixing material comprises the following components by mass: 60 to 90 parts of phosphogypsum, 5 to 10 parts of potassium feldspar, 5 to 20 parts of rock phosphate, 0.5 to 5 parts of a water retention agent and 0.5 to 5 parts of additives. The preparation method comprises the step of mixing the components of the water-retention sand-fixing material. The water-retention sand-fixing material has water-retention sand-fixing function, and can improve saline soil, improve soil structure and improve physic-chemical and biochemical properties of the soil, provides medium-trace elements for plants, and provides good growing environment for the plants. The water-retention sand-fixing material is environmentally-friendly, weather-resistant, long in service life and low in cost of production. The preparation method is simple in process, low in requirement on equipment and energy-saving, and can reduce cost.

Description

technical field [0001] The invention relates to a water-retaining and sand-fixing material, a preparation method and application thereof. Background technique [0002] According to the results of the second monitoring of desertified land by the State Forestry Administration, by the end of 2005, the national desertified land area reached 1.743 million square kilometers, equivalent to the size of 10 Guangdong provinces, accounting for 18% of the national land area. According to dynamic observations, the expansion rate of land desertification in my country reaches 3436 square kilometers per year, which is equivalent to the total area of ​​Beijing. Desertification is a major environmental and social problem faced by mankind in the world today. Alxa League in Inner Mongolia used to be a natural pasture with rich water and grass in history, but now 85% of the land has been desertified. [0003] According to calculations by the Lanzhou Desert Institute of the Chinese Academy of S...
