Description
Technical field
The present invention relates to acidification, be specifically related to the serpentine after a kind of acidifying.
Background technology
Serpentine is a kind of general name of moisture rich magnesium silicate mineral, as antigorite, lizardite, choysotile etc. Their color is general normal is green hue, but also has light gray, white or yellow etc. Because they are dark green alternate as snakeskin often, so gain the name. The structure of serpentine often has curling shape, as fiber. Such serpentine is often taken as asbestos and uses. Block or fibrous serpentine all can have gloss, block as wax, fibrous as silk.
Hardness, between 2.5 to 4, containing a large amount of magnesium, comes from igneous rock.
In order to improve the application quality of serpentine, need to carry out acidification to serpentine.
Summary of the invention
The object of the invention is to overcome weak point in prior art, the serpentine after a kind of acidifying is provided.
Serpentine batching after acidifying is made up of serpentine, Concave-convex clay rod, sulfuric acid, quick dissolved sodium silicate, polyvinyl alcohol, hydroxypropyl methylcellulose and sodium carbonate.
The production method of the serpentine after acidifying: by abrasive dust in the serpentine batching input grinding machine after acidifying, the powder after abrasive dust is the serpentine after acidifying.
That serpentine has is heat-resisting, anticorrosive, wear-resisting, heat insulation, sound insulation and operational characteristic preferably, and block or fibrous serpentine all can have gloss, block as wax, fibrous as thread. The present invention selects the serpentine after pulverizing, grain fineness≤0.5 millimeter of serpentine.
Concave-convex clay rod has unique layer chain structure feature, and crystal is needle-like, fibrous or fiber collection shape. Concave-convex clay rod has unique dispersion, high temperature resistant, the anti-good colloidal nature such as saline and alkaline and higher adsorption capacity, and has certain plasticity and cohesive force, and the present invention selects grain fineness≤5 millimeter of Concave-convex clay rod.
It is 98% the concentrated sulfuric acid that sulfuric acid is selected concentration.
Quick dissolved sodium silicate is white granular 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, graininess, Powdered three kinds; Nonpoisonous and tasteless, graininess can be dissolved in 80--90 DEG C of water, pulverously after other powders pre-dispersed, 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, good film forming and the feature such as resistance to enzyme, 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 serpentine pH value after acidifying.
The present invention is achieved by following technical proposals:
1, the batching of the serpentine after acidifying is made up of following component by weight percentage: serpentine 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.
2, the production method of the serpentine after acidifying: by abrasive dust in the serpentine batching input grinding machine after acidifying, grain fineness≤0.074 millimeter, the powder after abrasive dust is the serpentine finished product after acidifying.
3, the half-finished production method of the serpentine after acidifying: stir in the mixer (1) input of the batching of serpentine mixture having been turned round, then dilute sulfuric acid is slowly added and carries out acidification in serpentine mixture; (2) by the serpentine mixture after acidification, push as serpentine tablet thickness≤3 millimeter of serpentine tablet by twin rollers; (3) serpentine tablet is transported to roasting in swinging drying oven, roasting time is 1～3 hour, sintering temperature is controlled at 300～400 DEG C, serpentine tablet water content≤2% after roasting, serpentine tablet after roasting is the serpentine semi-finished product after acidifying, and PCm is weight percentage.
4, the batching of serpentine tablet is made up of following component by weight percentage: serpentine mixture 75～95% and dilute sulfuric acid 5～25%.
5, the batching of serpentine mixture is made up of following component by weight percentage: serpentine 70～92% and Concave-convex clay rod 8～30%.
6, the batching of dilute sulfuric acid is made up of following component by weight percentage: the concentrated sulfuric acid 1～25% that concentration is 98% and water 75～99%, the concentrated sulfuric acid percentage that concentration is 98% is weight percentage.
The production method of the serpentine after acidifying takes first acidifying to carry out compounding ingredient again, can avoid sulfuric acid and quick dissolved sodium silicate, polyvinyl alcohol, hydroxypropyl methylcellulose and sodium carbonate generation chemical reaction, give full play to raw-material characteristic separately in batching, and obtain complementation, guarantee the serpentine inherent quality after acidifying.
According to the needs of product quality, adopt sodium carbonate to adjust the serpentine pH value after acidifying, method is simple.
After the acidified processing of serpentine, pH value is controlled at 5.5～7.0, can improve the utilization rate of serpentine.
Serpentine after acidifying has good adsorptivity, thixotropy, heat endurance, plasticity and close-burning feature.
Serpentine after acidifying is applicable to produce environment-friendly materials, construction material, blowing agent and fire product.
