Embodiment Construction

[0031] Below in conjunction with embodiment the present invention will be further described:

[0032] 1. The green smear clay ingredients after sodiumization are composed of the following components by weight percentage: green smear clay flakes 95.6%, instant sodium silicate 2.1%, polyvinyl alcohol 1.6%, hydroxypropyl methylcellulose 0.5% and sodium acid pyrophosphate 0.2%.

[0033] 2. The production method of the green smectite clay after the sodiumization: input the ingredients of the green smectite clay after the sodiumization into the mill for grinding, the particle fineness is ≤0.074 mm, and the powder after grinding is the sodiumized Green smudged clay.

[0034] 3. The production method of green smectite clay flakes: (1) input the green smear clay mixture into the soaking tank, then slowly add water into the green smectite clay mixture to soak and sodiumize, and the soaking time for sodium is 48 hours; (2) take out The soaked green smear clay mixture is input into a tw...

Abstract

The invention discloses a sodium-treated green smectite clay. The main point of the technical scheme is that the sodium-treated green smectite clay is composed of green stilt clay, magnesium oxide, sodium carbonate, instant sodium silicate, polyethylene Alcohol, hydroxypropyl methylcellulose and sodium acid pyrophosphate; the sodiumized green smear clay ingredients are input into the mill for grinding, and the powder after grinding is sodium green stilt clay . According to the needs of product quality, sodium acid pyrophosphate is used to adjust the pH value of the green smear clay after sodiumization. The sodium smear clay can improve the water absorption rate, colloid price, expansion multiple, colloid Viscosity, cation exchange capacity, dispersibility and suspension rate in aqueous media. Sodiumized green smectite clay has the characteristics of good thixotropy, lubricity, thermal stability, high plasticity and strong cohesiveness. Sodiumized green smear clay is suitable for the production of products in the fields of industry, agriculture, construction and fire protection.

Description

technical field [0001] The invention relates to sodium treatment, in particular to a sodium-treated green smectite 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] Chloromontmorillonite is the product of the transformation from montmorillonite to chlorite. It is in the form of thin sheets wrapped on the surface of the particles or filled between the particles. It has both the needle-like structure of chlorite and the grid-like structure of montmorillonite. , contains more iron and magnesium, and has certain acid sensitivity and water sensitivity. [0004] The green smear layer is a mineral that is easy to swell when it meets water, and it is easy to cause clay swelling and dispersion to cause formation damage. [000...
