Problems solved by technology

[0003] In the chlorite mining area, excavators are used for mechanized mining of chlorite raw ore. What is excavated is a kind of dense massive chlorite raw ore, which cannot be directly used for acidification treatment. Most of them are crushed into fine particles by pulverizers. It is easy to destroy the crystal structure of chlorite
[0004] After the acidification treatment, there is no subsequent auxiliary modification treatment, and the quality of chlorite products cannot be comprehensively improved

Embodiment Construction

[0026] Below in conjunction with embodiment the present invention will be further described:

[0027] 1. The acidified chlorite ingredients are composed of the following components by weight percentage: 94.5% of acidified chlorite semi-finished products, 2.3% of instant sodium silicate, 2% of polyvinyl alcohol, and 1% of hydroxypropyl methylcellulose and Sodium Carbonate 0.2%.

[0028] 2. The production method of the acidified chlorite: input the acidified chlorite ingredients into the mill for grinding, the particle fineness is ≤0.074 mm, and the powder after grinding is the acidified chlorite finished product.

[0029] 3. The production method of acidified chlorite semi-finished products: (1) first input the naturally weathered chlorite into the running mixer, and then slowly add dilute sulfuric acid into the naturally weathered chlorite for acidification; (2) put After the acidification treatment, the chlorite is extruded into chlorite flakes by a roller machine, and the t...

Abstract

The invention discloses acidified chlorite. According to the technical scheme, the acidified chlorite is characterized by consisting of chlorite, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate. A production method for the acidified chlorite comprises the steps of feeding acidified chlorite ingredients into a mill, and milling to obtain powder, namely the acidified chlorite. According to the requirement of product quality, the pH value of the acidified chlorite is adjusted by adopting the sodium carbonate. The method is simple and feasible. By fully utilizing solar energy, alternating wind and rain and alternating cold and heat, the natural weathering effect of raw chlorite is promoted, the disintegrating effect of the raw chlorite is improved, and dispersion of the raw chlorite is accelerated. The acidified chlorite has relatively good adsorptivity, thixotropy, lubricating property, thermal stability and plasticity. The acidified chlorite is suitable for producing adsorbents, suspending agents, lubricating agents, linoleums, papers, pesticides and fillers of firefighting products.

Description

technical field [0001] The invention relates to acidification treatment, in particular to acidified chlorite. Background technique [0002] Chlorite is a kind of aluminosilicate mineral, which often coexists with authigenic quartz. It is in the shape of needles, pompoms, and roses. Its occurrence in the pores is pore lining and pore filling. Generally, the coniferous chlorites are mostly pore liners wrapped on the surface of the particles, while the pompom-like and rose-like ones are filled in the pores. Chlorite can be transformed from minerals such as biotite, hornblende, and montmorillonite. Authigenic chlorite is generally rich in high-valent iron ions, and it is easy to produce precipitation when it interacts with HCL and other acids in drilling fluids, causing reservoir damage. , is an acid-sensitive mineral. [0003] In the chlorite mining area, excavators are used for mechanized mining of chlorite raw ore. What is excavated is a kind of dense massive chlorite raw o...
