Embodiment Construction

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

[0028] 1. The acidified green smear clay ingredients are composed of the following components by weight percentage: 94.5% of acidified green smear clay semi-finished products, 2.3% instant sodium silicate, 2% polyvinyl alcohol, hydroxypropyl methylcellulose 1% and Sodium Carbonate 0.2%.

[0029] 2. The production method of the acidified green smear clay: input the acidified green smear clay ingredients into the mill for grinding, the particle fineness is ≤0.074 mm, and the powder after grinding is the acidified green smear Clay finished.

[0030] 3. The production method of semi-finished green smectite clay after acidification: (1) first input the naturally weathered green smectite clay into the mixer that has been running, and then slowly add dilute sulfuric acid into the naturally weathered green stilt clay for acidification treatment ; (2) the green smectite clay after the acidi...

Abstract

The invention discloses acidized green montmorillonite mixed-layer clay. According to the technical scheme, the acidized green montmorillonite mixed-layer clay is characterized by being prepared from ingredients including green montmorillonite mixed-layer clay, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxyl propyl methyl cellulose and sodium carbonate. A production method of the acidized green montmorillonite mixed-layer clay comprises the step of conveying the ingredients of the acidized green montmorillonite mixed-layer clay into a mill to mill powder, wherein the milled powdery substance is the acidized green montmorillonite mixed-layer clay. By sufficiently utilizing solar energy, wind and rain alternation and the passing of time, the natural weathering effect for a raw ore of green montmorillonite mixed-layer clay is promoted, the disintegration effect for the raw ore of the green montmorillonite mixed-layer clay is improved, and the dispersion of the raw ore of the green montmorillonite mixed-layer clay is accelerated. By using the acidized green montmorillonite mixed-layer clay, the adsorption property of the green montmorillonite mixed-layer clay can be greatly improved, the special surface area and porosity of the green montmorillonite mixed-layer clay can be greatly increased, meanwhile, the colloid viscosity of the acidized green montmorillonite mixed-layer clay can be increased, and the pH value of the acidized green montmorillonite mixed-layer clay can be regulated. The acidized green montmorillonite mixed-layer clay is suitable for producing products in the fields of industry, agriculture, construction and fire protection.

Description

technical field [0001] The invention relates to acidification treatment, in particular to an acidified green smectite clay. Background technique [0002] 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. [0003] Green smectite is a mineral that swells easily when exposed to water. It is easy to cause formation damage due to clay swelling and dispersion. In order to improve the related properties of green smectite clay, it is necessary to acidify the green smectite clay. [0004] In the green smectite clay mining area, excavators are used to mechanize the green smectite clay ore. What is excavated is a dense and massive green smectite clay o...
