Description
Technical field
The present invention relates to acidification, be specifically related to the volcanic ash after a kind of acidifying.
Background technology
Volcanic ash refers to and is gone out by volcanic eruption and the diameter rubble less than 2 millimeters and mineral particles, in fulminant volcanic activity, solid stone and molten slurry are broken down into trickle particle and form volcanic ash, substantial amounts of volcanic ash is deposited near volcanic crater, and accumulation over a long time is mixed in together with the earth of surrounding.
In order to improve pozzuolanic application quality, it is necessary to volcanic ash 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 volcanic ash after a kind of acidifying.
Volcanic ash dispensing after acidifying is made up of volcanic ash, attapulgite clay, magnesium oxide, sulphuric acid, quick dissolved sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate.
Pozzuolanic production method after acidifying: the volcanic ash dispensing after acidifying is inputted pulverizing in grinding machine, and the powder after pulverizing is the volcanic ash after acidifying.
Volcanic ash, often in isochrome dark-grey, yellow, white, is piled up and is become tufa stone after compressing, and it has pozzolanic activity, there is a number of active silica and activated alumina isoreactivity component.
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 pozzuolanic colloidal property.
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 volcanic ash pH value after adjusting acidifying in the present invention.
The technical scheme is that:
1, the volcanic ash dispensing after acidifying is made up of following component by weight percentage: volcanic ash 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 pozzuolanic production method after acidifying: the volcanic ash dispensing after acidifying is inputted pulverizing in grinding machine, and fineness of the particles≤0.074 millimeter, the powder after pulverizing is the volcanic ash finished product after acidifying.
3, the half-finished production method of volcanic ash after acidifying: (1) the dispensing of volcanic ash mixture is inputted stirring in the blender operated, then dilute sulfuric acid is slowly added in volcanic ash mixture carry out acidification；(2), by the volcanic ash mixture after acidification, it is volcanic ash tablet, thickness≤3 millimeter of volcanic ash tablet by twin rollers extruding；(3) volcanic ash tablet is transported to roasting in swinging drying oven, roasting time is 1～3 hour, sintering temperature controls at 300～400 DEG C, volcanic ash tablet water content≤2% after roasting, volcanic ash tablet after roasting is the volcanic ash semi-finished product after acidifying, and PCm is weight percentage.
4, the dispensing of volcanic ash tablet is made up of following component by weight percentage: volcanic ash mixture 75～95% and dilute sulfuric acid 5～25%.
5, the dispensing of volcanic ash mixture is made up of following component by weight percentage: volcanic ash 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.
Pozzuolanic production method 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 volcanic ash inherent quality after acidifying.
Needs according to product quality, the volcanic ash pH value after adopting sodium carbonate to adjust acidifying, method is simple.
After the acidified process of volcanic ash, volcanic ash pH value controls 5.5～7.0, it is possible to improve pozzuolanic utilization rate, not only can bring good economic benefit, environmental benefit and social benefit, and can realize turning waste into wealth.
Volcanic ash after acidifying has good adsorptivity, thixotropy, heat stability, plasticity and close-burning feature.
Volcanic ash after acidifying is applicable to produce environment-friendly materials, insecticide carrier, construction material, daily chemicals filler, foaming agent and fire product.
