Embodiment Construction

[0027] Below in conjunction with embodiment the present invention will be further described:

[0028] 1. The attapulgite clay ingredients after sodiumization are composed of the following components by weight percentage: attapulgite clay flakes 96.1%, instant sodium silicate 2%, polyvinyl alcohol 1.5% and hydroxypropyl methylcellulose 0.4%.

[0029] 2. The production method of sodiumized attapulgite clay: input the ingredients of sodiumized attapulgite clay into a mill for grinding, the particle fineness is ≤0.074 mm, and the powder after grinding is sodiumized Attapulgite clay.

[0030] 3. The production method of attapulgite clay flakes: (1) Input the attapulgite clay mixture into the soaking tank, then slowly add water into the attapulgite clay mixture to soak for sodiumization, and the soaking time for sodiumization is 48 hours; (2) Take out The soaked attapulgite clay mixture is input into a twin-shaft mixer and stirred evenly, and then input into an extruder to extrude...

Abstract

The invention discloses sodium modified attapulgite clay, and the key points of the technical scheme are that: the sodium modified attapulgite clay comprises the ingredients of attapulgite clay, sodium carbonate, magnesium oxide, instant sodium silicate, polyvinyl alcohol and hydroxypropyl methyl cellulose. A production method of the sodium modified attapulgite clay is as follows: sodium modified attapulgite clay ingredients are transported into a mill for milling powder, and the milled powder is the sodium modified attapulgite clay. The sodium modified attapulgite clay can improve the water absorption rate, colloid index, expansion times, colloid viscosity, rheological properties, cation exchange capacity, dispersibility and suspension rate in an aqueous medium of the attapulgite clay. The sodium modified attapulgite clay has the characteristics of good thixotropy, lubrication, thermal stability, strong adhesion, high plasticity. The sodium modified attapulgite clay is applicable to the production of products of industry, agriculture, building and fire control and other areas.

Description

technical field [0001] The invention relates to sodium treatment, in particular to attapulgite clay after sodium treatment. Background technique [0002] In addition to attapulgite, attapulgite clay also contains minerals such as bentonite, kaolinite, hydromica, sepiolite, quartz, opal and carbonate. [0003] In the attapulgite clay mining area, the attapulgite clay ore is mechanized mined by excavators. What is excavated is a dense massive attapulgite clay ore. The attapulgite clay ore is relatively large and cannot be directly used for sodium treatment. For treatment, pulverizers are often used to break into fine particles for sodium treatment, which can easily destroy the crystal structure of attapulgite clay. [0004] The quality of attapulgite clay products cannot be fully improved without subsequent auxiliary modification treatment after sodium treatment. Contents of the invention [0005] The purpose of the present invention is to overcome the shortcomings in the ...
