Wollastonite is a kind of inorganic needle-like mineral, its feature is nontoxic, resistance to chemical attack, heat endurance and dimensionally stable good, there are glass and pearly luster, low water absorption and oil factor, mechanical property and electrical property excellent and there is certain strengthening action, the present invention selects the wollastonite mine tailing after pulverizing, grain fineness≤0.5 millimeter of wollastonite mine tailing.
Concave-convex clay rod has unique layer chain structure feature, and crystal is needle-like, threadiness or fiber collection shape.Concave-convex clay rod has unique dispersion, high temperature resistant, anti-good colloidal nature and the higher adsorption capacity such as saline and alkaline, and has certain plasticity and cohesive force, and the present invention selects grain fineness≤5 millimeter of Concave-convex clay rod.
Magnesia has the general character of basic anhydride, belongs to Binder Materials, can improve the colloidal property of wollastonite mine tailing.
Sulfuric acid select concentration be 98% the concentrated sulfuric acid.
Quick dissolved sodium silicate is white powder material, can rapid solution in water, have 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, 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 methylcellulose has thickening capabilities, salt discharge, pH stability, water-retaining property, dimensional stability, excellent film forming and the feature such as resistance to enzymatic, dispersiveness and caking property widely.
Sodium carbonate has the general character and the heat endurance of salt, soluble in water, and its aqueous solution is alkalescence, in the present invention for adjusting the wollastonite mine tailing pH value after acidifying.
The present invention is achieved by following technical proposals:
1, the wollastonite mine tailing batching after acidifying is made up of following component by weight percentage: wollastonite mine tailing semi-finished product 90 ~ 98%, quick dissolved sodium silicate 0.1 ~ 5%, polyvinyl alcohol 0.1 ~ 5%, hydroxypropyl methylcellulose 0.01 ~ 3% and sodium carbonate 0 ~ 3% after acidifying.
The production method of the wollastonite mine tailing 2, after acidifying: by abrasive dust in the wollastonite mine tailing batching input grinding machine after acidifying, grain fineness≤0.074 millimeter, the powder after abrasive dust is the wollastonite mine tailing finished product after acidifying.
3, the half-finished production method of wollastonite mine tailing after acidifying: stir in the mixer (1) input of the batching of wollastonite Tailings mixture operated, then dilute sulfuric acid is slowly added in wollastonite Tailings mixture carry out acidification; (2), by the wollastonite Tailings mixture after acidification, be wollastonite mine tailing tablet by twin rollers extruding, thickness≤3 millimeter of wollastonite mine tailing tablet; (3) wollastonite mine tailing tablet is transported to roasting in swinging drying oven, roasting time is 1 ~ 3 hour, sintering temperature controls at 250 ~ 350 DEG C, wollastonite mine tailing tablet water content≤5% after roasting, wollastonite mine tailing tablet after roasting is the wollastonite mine tailing semi-finished product after acidifying, and PCm is weight percentage.
4, the batching of wollastonite mine tailing tablet is made up of following component by weight percentage: wollastonite Tailings mixture 75 ~ 95% and dilute sulfuric acid 5 ~ 25%.
