Description

Illite clay after acidifying
Technical field
The present invention relates to acidification, be specifically related to the illite clay after a kind of acidifying.
Background technology
A kind of clay mineral that illite is common is often formed by white mica potash feldspar air slaking, and originates in argillaceous rocks or formed by other mineral alterations.It is often the middle transition mineral forming other clay minerals.Pure illite clay is white but often dyes yellowish green brown isochrome because of impurity, and impure more gray or black earthy, property are crisp, frangible, exquisite quality, smooth, hardness is little, is long placed in water does not expand and loose have research of chaotic phenomenon.
In illite clay mining area, usage mining machine carries out mechanical mining illite clay raw ore, what excavate is a kind of compact massive illite clay raw ore, the volume of illite clay raw ore is bigger, cannot be directly used to acidification, it is adopt pulverizer to carry out being broken for tiny granule mostly, it is easy to destroy the crystal structure of illite clay.
Do not carry out follow-up complementary modification, it is impossible to improve the quality of illite clay product after acidification comprehensively.
Summary of the invention
It is an object of the invention to overcome weak point in prior art, it is provided that the illite clay after a kind of acidifying.
Illite clay dispensing after acidifying is made up of illite clay, sulphuric acid, quick dissolved sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate.
The production method of the illite clay after acidifying: the illite clay dispensing after acidifying is inputted pulverizing in grinding machine, and the powder after pulverizing is the illite clay after acidifying.
Illite clay has rich potassium, high alumina, low ferrum and superior chemistry, the physical property such as smooth, bright, fine and smooth, heat-resisting.
Sulphuric acid selects concentration to be the concentrated sulphuric acid of 98%.
Quick dissolved sodium silicate is white powder material, can rapid solution in water, have that cohesive force is strong, intensity is higher, acid resistance, heat-resist, the feature of alkali resistance and poor water resistance.
Polyethenol series white solid, external form divide cotton-shaped, graininess, Powdered three kinds;Nonpoisonous and tasteless, graininess can be dissolved in 80--90 DEG C of water, pulverous other powders pre-dispersed after can dissolve at normal temperatures.There is good viscosity, polymerism, caking property and water-retaining property.
Hydroxypropyl methyl cellulose has thickening capabilities, salt discharge, pH stability, water-retaining property, dimensional stability, excellent film property and the feature such as resistance to enzyme, dispersibility and caking property widely.
Sodium carbonate has the general character and the heat stability of salt, soluble in water, and its aqueous solution, in alkalescence, is used for the illite clay pH value after adjusting acidifying in the present invention.
The technical scheme is that:
1, the illite clay dispensing after acidifying is made up of following component by weight percentage: illite clay semi-finished product 90~98% after acidifying, quick dissolved sodium silicate 0.1~5%, polyvinyl alcohol 0.1~5%, hydroxypropyl methyl cellulose 0.01~3% and sodium carbonate 0~3%.
2, the production method of the illite clay after acidifying: the illite clay dispensing after acidifying is inputted pulverizing in grinding machine, and fineness of the particles≤0.074 millimeter, the powder after pulverizing is the illite clay finished product after acidifying.
3, the half-finished production method of illite clay after acidifying: (1) first the illite clay after weathering is inputted in the blender operated, then dilute sulfuric acid is slowly added in the illite clay after weathering carry out acidification;(2), by the illite clay after acidification, it is illite clay tablet, thickness≤3 millimeter of illite clay tablet by twin rollers extruding;(3) illite clay tablet is transported to roasting in swinging drying oven, roasting time is 1~3 hour, sintering temperature controls at 250~350 DEG C, illite clay tablet water content≤5% after roasting, illite clay tablet after roasting is the illite clay semi-finished product after acidifying, and PCm is weight percentage.
4, the dispensing of illite clay tablet is made up of following component by weight percentage: illite clay 55~75% after weathering and dilute sulfuric acid 25~45%.
5, the dispensing of dilute sulfuric acid is made up of following component by weight percentage: concentration is the concentrated sulphuric acid 1~5% of 98%, water 95~99%, concentration be 98% concentrated sulphuric acid percentage ratio be weight percentage.
6, illite clay raw ore needs the time weathering more than two winters, illite clay after the weathering that raw ore disintegrate is fine particle of large block compact, pick and be evident that barren rock block, Plant fiber and other earth impurity, illite clay fineness of the particles≤5 millimeter after weathering.
The production method of the illite clay after acidifying takes first acidifying to carry out compounding ingredient again, sulphuric acid and quick dissolved sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate generation chemical reaction can be avoided, give full play to raw-material respective characteristic in dispensing, and obtain complementation, it is ensured that the illite clay inherent quality after acidifying.
Needs according to product quality, the illite clay pH value after adopting sodium carbonate to adjust acidifying, method is simple.
The present invention makes full use of solar energy, wind and rain replaces and with the passage of time, promotes the weathering effect to illite clay raw ore, improves the disintegrate effect of illite clay raw ore, accelerates the dispersion of illite clay raw ore.
Illite clay after acidifying has good adsorptivity, thixotropy, lubricity, heat stability and plasticity feature.
Illite clay after acidifying is applicable to produce cosmetics, filler, soil regulator, feed additive, the pollution purification of nuclear industry, environmental conservation and fire-fighting quipment.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
1, the illite clay dispensing after acidifying is made up of following component by weight percentage: illite clay semi-finished product 94.5% after acidifying, quick dissolved sodium silicate 2.3%, polyvinyl alcohol 2%, hydroxypropyl methyl cellulose 1% and sodium carbonate 0.2%.
2, the production method of the illite clay after acidifying: the illite clay dispensing after acidifying is inputted pulverizing in grinding machine, and fineness of the particles≤0.074 millimeter, the powder after pulverizing is the illite clay finished product after acidifying.
3, the half-finished production method of illite clay after acidifying: (1) first the illite clay after weathering is inputted in the blender operated, then dilute sulfuric acid is slowly added in the illite clay after weathering carry out acidification;(2), by the illite clay after acidification, it is illite clay tablet, thickness≤3 millimeter of illite clay tablet by twin rollers extruding;(3) illite clay tablet is transported to roasting in swinging drying oven, roasting time is 2 hours, sintering temperature controls at 280~320 DEG C, illite clay tablet water content≤5% after roasting, and the illite clay tablet after roasting is the illite clay semi-finished product after acidifying.
4, the dispensing of illite clay tablet is made up of following component by weight percentage: illite clay 68% after weathering and dilute sulfuric acid 32%.
