Embodiment Construction

[0030] Below in conjunction with embodiment the present invention will be further described:

[0031] 1. The ingredients of the mixed layer clay after sodiumization are composed of the following components by weight percentage: 95.6% of the mixed layer clay flakes, 2.1% instant sodium silicate, 1.6% polyvinyl alcohol, hydroxypropyl methyl Cellulose 0.5% and Sodium Acid Pyrophosphate 0.2%.

[0032] 2. The production method of the sodium-treated I-green mixed-layer clay: input the ingredients of the sodium-treated I-green mixed-layer clay into a mill for grinding, the particle fineness is ≤0.074 mm, and the powder after grinding is sodium The latter is the mixed layer clay of Yilu.

[0033] 3. The production method of the I-green mixed-layer clay flakes: (1) Input the I-green mixed-layer clay mixture into the soaking tank, then slowly add water into the I-green mixed-layer clay mixture for soaking and sodiumization, and the soaking time for sodiumization is 48 hours ; (2) Take...

Abstract

The invention discloses a sodium-modified illite-chlorite mixed-layer clay. The technical scheme is as follows: the sodium-modified illite-chlorite mixed-layer clay is composed of illite-chlorite mixed-layer clay, magnesium oxide, sodium carbonate, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methylcellulose and sodium acid pyrophosphate. The sodium-modified illite-chlorite mixed-layer clay materials are milled into powder in a mill, and the powder is the sodium-modified illite-chlorite mixed-layer clay. The sodium acid pyrophosphate is adopted to regulate the pH value of the illite-chlorite mixed-layer clay according to the product quality demands. The sodium modification can enhance the water absorptivity, colloid index, expansion coefficient, colloid viscosity, cation exchange capacity, and dispersivity and suspension percentage in an aqueous medium of the illite-chlorite mixed-layer clay. The sodium-modified illite-chlorite mixed-layer clay has the characteristics of favorable thixotropy, favorable lubricating property, favorable heat stability, higher plasticity and higher binding property. The sodium-modified illite-chlorite mixed-layer clay is suitable for producing products in the fields of industry, agriculture, construction, firefighting and the like.

Description

technical field [0001] The invention relates to sodium treatment, in particular to a sodium-treated eileenite mixed layer clay. Background technique [0002] If two or more clay mineral structural unit layers are regularly superimposed on each other, it is called an ordered mixed layer, otherwise it is called a disordered mixed layer, such as an illite mixed layer, a green smectite layer, and an iridescent mixed layer. [0003] There are a large amount of mixed layer clay in many areas of our country, but these mixed layer clay is rarely used in the actual production of products. [0004] In the Yilu mixed-layer clay mining area, excavators are used to mechanize the raw ore of the mixed-layer clay. The raw ore of the mixed-layer clay is excavated. For sodium treatment, pulverizers are often used to break into fine particles for sodium treatment, which can easily destroy the crystal structure of the mixed-layer clay. [0005] After the sodium treatment, there is no subseque...
