Abstract
The invention discloses an acidified illite-chlorite mixed-layer clay. The technical scheme is as follows: the acidified illite-chlorite mixed-layer clay is composed of illite-chlorite mixed-layer clay, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methylcellulose and sodium carbonate. The production method of the acidified illite-chlorite mixed-layer clay comprises the following steps: inputting the acidified illite-chlorite mixed-layer clay materials into a mill, and milling to obtain the powdery acidified illite-chlorite mixed-layer clay. The acidified illite-chlorite mixed-layer clay fully utilizes the solar energy, the alternate rain and wind and the four seasons, promotes the natural weathering effect on the illite-chlorite mixed-layer clay raw ores, and accelerates the dispersion of the illite-chlorite mixed-layer clay raw ores. On the premise of greatly enhancing the adsorbability, specific area and porosity of the illite-chlorite mixed-layer clay, the colloid viscosity of the acidified illite-chlorite mixed-layer clay can be enhanced, and the pH value of the acidified illite-chlorite mixed-layer clay can be adjusted. The acidified illite-chlorite mixed-layer clay is suitable for producing products in the fields of industry, agriculture, construction and firefighting.
Description
Technical field
The present invention relates to acidification, be specifically related to her the green mixed-layer clay after a kind of acidifying.
Background technology
If it is stacked that two or more clay mineral structure Institutional Layers are made regular alternating layers, claim ordered, otherwise be called disorded, as illite/smectite mixed layer, green layer, her the green mixed layer etc. of deceiving people.
China all stores in many areas a large amount of her green mixed-layer clays, but these her green mixed-layer clays are seldom used in the product of actual production.
In her green mixed-layer clay mining area, usage mining machine carries out her green mixed-layer clay raw ore of mechanical mining, excavate out be her green mixed-layer clay raw ore of a kind of compact mass, her volume of green mixed-layer clay raw ore is larger, can not be directly used in acidification, normal employing pulverizer is broken for tiny particle and carries out acidification, is easy to destroy the crystalline structure of her green mixed-layer clay.
After her green mixed-layer clay is acidified, absorption property is to be improved, but the colloidal property of her green mixed-layer clay will significantly decline.
Summary of the invention
The object of the invention is to overcome weak point in prior art, her the green mixed-layer clay after a kind of acidifying is provided.
Her green mixed-layer clay after acidifying is prepared burden and is comprised of her green mixed-layer clay, sulfuric acid, quick dissolved sodium silicate, polyvinyl alcohol, Vltra tears and sodium carbonate.
The production method of her the green mixed-layer clay after acidifying: by abrasive dust in the green mixed-layer clay batching of she after acidifying input grinding machine, the meal after abrasive dust is her the green mixed-layer clay after acidifying.
China's salt lake clay mineral be take illite-chlorite as principal character, containing a small amount of montmorillonite and kaolinite, there are a large amount of her green mixed-layer clays, salt lake clay chemistry composition is similar to illite clay chemical composition, and the high-content of her green mixed-layer clay in Hailaer Basin, Northeast China clay mineral can reach more than 35%.
It is 98% the vitriol oil that sulfuric acid is selected concentration.
Quick dissolved sodium silicate is white pulverulent material, can be dissolved in fast water, has that cohesive force is strong, intensity is higher, acid resistance, good heat resistance, the feature of alkali resistance and poor water resistance.
Polyethenol series white solid, that external form is divided is cotton-shaped, particulate state, Powdered three kinds; Nonpoisonous and tasteless, particulate state can be dissolved in 80--90 ℃ of water, pulverously after other powders pre-dispersed, can dissolve at normal temperatures.There is good viscosity, polymerizability, cohesiveness and water-retentivity.
Vltra tears has thickening capabilities, salt discharge, pH stability, water-retentivity, dimensional stability, good film-forming properties and the feature such as resistance to enzyme, dispersiveness and cohesiveness widely.
Sodium carbonate has the general character and the thermostability of salt, soluble in water, and its aqueous solution is alkalescence, in the present invention for adjusting her the green mixed-layer clay pH value after acidifying.
The present invention is achieved by following technical proposals:
1, the green mixed-layer clay batching of she after acidifying is comprised of following component by weight percentage: her the green mixed-layer clay work in-process 90～98% after acidifying, quick dissolved sodium silicate 0.1～5%, polyvinyl alcohol 0.1～5%, Vltra tears 0.01～3% and sodium carbonate 0～3%.
2, the production method of her the green mixed-layer clay after acidifying: by abrasive dust in the green mixed-layer clay batching of she after acidifying input grinding machine, particle fineness≤0.074 millimeter, the meal after abrasive dust is her the green mixed-layer clay finished product after acidifying.
3, the half-finished production method of her green mixed-layer clay after acidifying: in the stirrer (1) first her the green mixed-layer clay input after weathering having been turned round, then dilute sulphuric acid is slowly added in her the green mixed-layer clay after weathering and carries out acidification; (2) by her the green mixed-layer clay after acidification, by twin rollers, push as her green mixed-layer clay flap thickness≤3 millimeter of her green mixed-layer clay flap; (3) her green mixed-layer clay flap is transported to roasting in rotary type stoving oven, roasting time is 1～3 hour, maturing temperature is controlled at 250～350 ℃, her green mixed-layer clay flap water content≤5% after roasting, her green mixed-layer clay flap after roasting is her the green mixed-layer clay work in-process after acidifying, and PCm is weight percentage.
4, the batching of her green mixed-layer clay flap is comprised of following component by weight percentage: her green mixed-layer clay 55～75% and the dilute sulphuric acid 25～45% after weathering.
5, the batching of dilute sulphuric acid is comprised of following component by weight percentage: the vitriol oil 1～5% that concentration is 98%, and water 95～99%, the vitriol oil per-cent that concentration is 98% is weight percentage.
6, her green mixed-layer clay raw ore need to be through two time weathering more than winter, her green mixed-layer clay from the weathering that the raw ore disintegration of large block compact is fine particle, pick obvious visible barren rock piece, vegetable fibre and other earth impurity, her green mixed-layer clay particle fineness≤5 millimeter after weathering.
The production method of her the green mixed-layer clay after acidifying takes first acidifying to carry out compounding ingredient again, can avoid sulfuric acid and quick dissolved sodium silicate, polyvinyl alcohol, Vltra tears and sodium carbonate generation chemical reaction, give full play to raw-material characteristic separately in batching, and obtain complementation, guarantee her the green mixed-layer clay inner quality after acidifying.
According to the needs of quality product, adopt sodium carbonate to adjust her the green mixed-layer clay pH value after acidifying, method is simple.
The present invention makes full use of sun power, wind and rain alternately and with the passage of time, promotes the weathering effect to her green mixed-layer clay raw ore, improves the disintegration effect of her green mixed-layer clay raw ore, accelerates the dispersion of her green mixed-layer clay raw ore.
Her green mixed-layer clay after acidifying, when increasing substantially the absorption property of her green mixed-layer clay, specific surface area, porosity, can increase the colloid viscosity of her the green mixed-layer clay after acidifying and adjust her the green mixed-layer clay pH value after acidifying.
Her green mixed-layer clay after acidifying is applicable to the product of manufacture, agricultural, building and fire-fighting domain.
