Description

Pyrophillite after acidifying
Technical field
The present invention relates to acidification, be specifically related to the pyrophillite after a kind of acidifying。
Background technology
Agalmatolite Ores In China aboundresources, exploitation aspect major product is ceramic grade, refractory material level, glass level, engraving level, scale is less than normal with external ratio, product specification is not high, deep processed product portion is few, thus economic benefit is not good enough, what solve problem above it is critical only that the research and development strengthening pyrophyllite deep processed product。
Pyrophillite is the one of clay mineral, and Ore, based on bulk, also has earthy and fibrous, pyrophyllite often with the mineral intergrowth such as quartz, kaolinite, montmorillonite, dickite, sericite and kyanite, andalusite, corundum。
In order to improve the application quality of pyrophillite, it is necessary to pyrophillite is carried out acidification。
Summary of the invention
It is an object of the invention to overcome weak point in prior art, it is provided that the pyrophillite after a kind of acidifying。
Pyrophillite dispensing after acidifying is made up of pyrophillite, attapulgite clay, magnesium oxide, sulphuric acid, quick dissolved sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate。
The production method of the pyrophillite after acidifying: the pyrophillite dispensing after acidifying is inputted pulverizing in grinding machine, and the powder after pulverizing is the pyrophillite after acidifying。
Pyrophillite slip fluidity is good, good penetrability, and pyrophillite has good heat stability and little hygral expansion, for this, it is possible to for manufacture size accurately, the product of Heat stability is good, body drying shrinks little, indeformable, it is little to burn till crack, firing whiteness 90~96%, refractoriness >=1700 DEG C, insulation, thermal insulation good, stable chemical performance, only at high temperature could by sulfuric acid decomposition, the present invention selects the pyrophillite after pulverizing, fineness of the particles≤0.5 millimeter of pyrophillite。
Attapulgite clay has the layer chain structure feature of uniqueness, and crystal is needle-like, fibrous or fiber collection shape。Attapulgite clay has the dispersion of uniqueness, good colloidal nature and the higher absorbability such as saline and alkaline high temperature resistant, anti-, and has certain plasticity and cohesive force, and the present invention selects fineness of the particles≤5 millimeter of attapulgite clay。
Magnesium oxide has the general character of basic anhydride, belongs to Binder Materials, can improve the colloidal property of pyrophillite。
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 pyrophillite pH value after adjusting acidifying in the present invention。
The technical scheme is that:
1, the pyrophillite dispensing after acidifying is made up of following component by weight percentage: pyrophillite 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 pyrophillite after acidifying: the pyrophillite dispensing after acidifying is inputted pulverizing in grinding machine, and fineness of the particles≤0.074 millimeter, the powder after pulverizing is the pyrophillite finished product after acidifying。
3, the half-finished production method of pyrophillite after acidifying: (1) the dispensing of pyrophillite mixture is inputted stirring in the blender operated, then dilute sulfuric acid is slowly added in pyrophillite mixture carry out acidification;(2), by the pyrophillite mixture after acidification, it is pyrophillite tablet, thickness≤3 millimeter of pyrophillite tablet by twin rollers extruding;(3) pyrophillite tablet is transported to roasting in swinging drying oven, roasting time is 1~3 hour, sintering temperature controls at 300~400 DEG C, pyrophillite tablet water content≤2% after roasting, pyrophillite tablet after roasting is the pyrophillite semi-finished product after acidifying, and PCm is weight percentage。
4, the dispensing of pyrophillite tablet is made up of following component by weight percentage: pyrophillite mixture 75~95% and dilute sulfuric acid 5~25%。
5, the dispensing of pyrophillite mixture is made up of following component by weight percentage: pyrophillite 68~92%, attapulgite clay 5~30% and magnesium oxide 0.1~3%。
6, the dispensing of dilute sulfuric acid is made up of following component by weight percentage: concentration is concentrated sulphuric acid 1~25% and the water 75~99% of 98%, concentration be 98% concentrated sulphuric acid percentage ratio be weight percentage。
The production method of the pyrophillite 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 pyrophillite inherent quality after acidifying。
Needs according to product quality, the pyrophillite pH value after adopting sodium carbonate to adjust acidifying, method is simple。
After the acidified process of pyrophillite, pH value controls 5.5~7.0, it is possible to improve the utilization rate of pyrophillite。
Pyrophillite after acidifying has good adsorptivity, thixotropy, heat stability, plasticity and close-burning feature。
Pyrophillite after acidifying is applicable to produce environment-friendly materials, construction material, foaming agent and fire product。
