Embodiment Construction

[0016] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0017] The present embodiment provides a kind of preparation method of bentonite mud, comprises the following steps:

[0018] Step 1: Select bentonite raw ore, crush, sieve out stones and impurities, and leave bentonite;

[0019] Step 2: Dry the bentonite, and then use a crusher to break it into granules, and then break it into tiny granules, and then spread it on the ground layer by layer. When there is no layer of bentonite, add a layer on top Sodium carbonate, a total of at least 10 layers of bentonite, the top layer is bentonite, after which it will be covered with a drape for sodiumization for 2-3 days;

[0020] Step 3: Put all the bentonite and sodium carbonate in step 2 into ...

Abstract

The invention is aimed at providing a preparing method of bentonite slurry. The method includes the steps of crushing bentonite raw ore, laying the raw ore on the ground layer by layer, adding a layerof sodium carbonate and high-molecular polymer synergist between every two layers for sodium treatment, performing mixing and pulverizing to form powder, laying the powder on the ground layer by layer, performing sodium treatment to obtain sodium treatment bentonite, adding the sodium treatment bentonite and the synergist to cement, sand and water to be stirred at a low speed and then a high speed to obtain bentonite cement slurry, taking a small amount of bentonite cement slurry to be poured into a test mold to be cured to obtain a test sample, and then detecting and ensuring the performanceof the test sample. The whole preparing method is good in bentonite sodium treatment effect and excellent in performance, by adding the sodium treatment bentonite and the synergist to the bentonite slurry, the bentonite slurry good in water absorption effect can be prepared, and the method is complete.

Description

technical field [0001] The invention relates to the field of bentonite, in particular to a preparation method of bentonite slurry. Background technique [0002] Bentonite is a non-metallic mineral with montmorillonite as the main mineral component. The structure of montmorillonite is a 2:1 crystal structure composed of two silicon-oxygen tetrahedra sandwiching a layer of aluminum-oxygen octahedron. The cement slurry is an important material in construction engineering. Adding bentonite to the cement slurry can improve the performance of the cement slurry. The bentonite has excellent water absorption and swelling properties. However, the preparation method for the mud with bentonite is not perfect at present, and a perfect preparation method is needed. Therefore, it is necessary to solve this problem. Contents of the invention [0003] In order to solve the above problems, the present invention provides a preparation method of bentonite mud. Firstly, the bentonite raw ore...
