Embodiment 1

[0042] Embodiment 1: Preparation of modified montmorillonite powder small test

[0043] A kind of production method of modified montmorillonite powder test, specifically comprises the following steps:

[0044] a. Mix sodium-based montmorillonite powder and deionized water according to the ratio of 1:15, disperse and make pulp, fully wet and stir for 1 hour, add anhydrous sodium carbonate according to the ratio of 1:30, and continue stirring until the mixture is uniform; at 49°C The rheological properties of the base pulp were determined to be 13, 9, 7, 5, 4, 3.5;

[0045] b. Settling the base slurry prepared in step a for 2h, centrifuging, measuring and adjusting the pH value of the base slurry to 12;

[0046] c. Shearing and stirring the base slurry prepared in step b, heating to 55°C, adding an organic cationic modifier in a proportion of 10%, heating to 9°C and continuing to stir evenly;

[0047] d. Separating and washing the base slurry prepared in step c, and then dryin...

Embodiment 2

[0059] Example 2: Pilot test for preparation of modified montmorillonite powder

[0060] A pilot production method of modified montmorillonite powder, specifically comprising the following steps:

[0061] a. Sieve the natural montmorillonite powder to remove low-grade and low-quality montmorillonite powder;

[0062] b. Mix sodium-based montmorillonite powder and deionized water according to the ratio of 1:8, disperse and make pulp, fully wet and stir for 1 hour, add anhydrous sodium carbonate according to the ratio of 1:10, and continue stirring until the mixture is uniform;

[0063] c. Settling the base slurry prepared in step b for 2h, centrifuging, measuring and adjusting the pH value of the base slurry to 12;

[0064] d. Shearing and stirring the base slurry prepared in step c, heating to 55°C, adding an organic cationic modifier in a proportion of 45%, heating to 9°C and continuing to stir evenly;

[0065] e. Separating and washing the base slurry prepared in step d, an...

Abstract

The invention discloses a production method of modified montmorillonite powder and a system thereof, and belongs to the technical field of modified montmorillonite powder. The production method disclosed by the invention sequentially comprises the steps of dispersion slurrying, sodium modification, standing for settlement, centrifuging, shear stirring, modification, solid-liquid separation, drying, grinding and packaging and the like; the modified montmorillonite powder with uniform form and stable performance is prepared; the technology is simple, and the energy consumption is reduced. The production system disclosed by the invention comprises a natural soil treatment device, a purifying and modifying device, a separating and drying device, a grinding and packaging device and a wastewatertreatment device, wherein the natural soil treatment device, the purifying and modifying device, the separating and drying device and the grinding and packaging device are communicated in turn; the wastewater treatment device is communicated with the separating and drying device and the purifying and modifying device through a pipeline respectively, so as to form a wastewater circulating loop. The production system has the advantages of compact and reasonable structure, strong industrial operability and good using effect.

Description

technical field [0001] The invention relates to the technical field of modified montmorillonite powder, in particular to a production method and system of modified montmorillonite powder. Background technique [0002] Montmorillonite powder is a composite of inorganic minerals and organic matter, which can form gels in various organic solvents, oils, and liquid resins, and has good thickening, thixotropy, suspension stability, high temperature stability, Lubricity, film-forming, water resistance and chemical stability, so it is widely used in coatings, paint inks, aviation, metallurgy, chemical fiber, petroleum and other industries. In terms of coatings, montmorillonite powder is generally used as an anti-sedimentation agent and thickener. It is used in metal anti-corrosion coatings with the characteristics of corrosion resistance, wear resistance, salt water erosion resistance, impact resistance, and not easy to wet; in the textile industry, montmorillonite powder It is ma...
