Description

Rectorite after acidifying
Technical field
The present invention relates to acidification, be specifically related to the Rectorite after a kind of acidifying.
Background technology
Rectorite leng a kind ofly has special construction, comparatively rare clay of laminar silicate mineral.Rectorite leng is met water electrode and is easily disperseed, film forming is smooth, the rectorite leng in the major part place of production and other clay pit associations, grade is lower, China is own finds rectorite leng mineral and Rectorite rock in many places, but it is reported except the rectorite leng found in Permian System In Zhongxiang, hubei rock have fairly large except, various places rectorite leng mineral reserves is all very little.
After Rectorite is acidified, absorption property can be improved, and does not carry out follow-up complementary modification after acidification, can not improve the quality of Rectorite product comprehensively.
Summary of the invention
The object of the invention is to overcome weak point in prior art, the Rectorite after a kind of acidifying is provided.
Rectorite batching after acidifying is made up of Rectorite, attapulgite clay, magnesium oxide, sulfuric acid, quick dissolved sodium silicate, polyvinyl alcohol, Vltra tears and sodium carbonate.
The production method of the Rectorite after acidifying: by abrasive dust in the Rectorite batching input grinding machine after acidifying, the meal after abrasive dust is the Rectorite after acidifying.
Rectorite leng mostly is finely squamose, also show lath-shaped, fiber needle-like crystal, main component is hydrous alumino silicates, many and clay pit association, the clay of mineralogical composition based on rectorite leng or containing certain proportion rectorite leng is called Rectorite, and the present invention selects particle fineness≤0.5 millimeter of Rectorite.
Attapulgite clay has unique layer chain-like structure feature, and crystal is needle-like, threadiness or fiber collection shape.Attapulgite clay has unique dispersion, high temperature resistant, anti-good colloidal property and the higher adsorptive power such as saline and alkaline, and has certain plasticity-and cohesive force.
Magnesium oxide has the general character of basic oxide, belongs to gelling material, can improve the colloidal property of Rectorite.
Sulfuric acid select concentration be 98% the vitriol oil.
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, particulate state, Powdered three kinds; Nonpoisonous and tasteless, particulate state 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, polymerizability, cohesiveness and water-retentivity.
Vltra tears has thickening capabilities, salt discharge, pH stability, water-retentivity, dimensional stability, excellent film-forming properties and the feature such as resistance to enzymatic, dispersiveness and cohesiveness widely.
Sodium carbonate has the general character and the thermostability of salt, soluble in water, and its aqueous solution is alkalescence, in the present invention for adjusting the Rectorite pH value after acidifying.
The present invention is achieved by following technical proposals:
1, the Rectorite batching after acidifying is made up of following component by weight percentage: the Rectorite work in-process 90 ~ 98% after acidifying, quick dissolved sodium silicate 0.1 ~ 5%, polyvinyl alcohol 0.1 ~ 5%, Vltra tears 0.01 ~ 3% and sodium carbonate 0 ~ 3%.
The production method of the Rectorite 2, after acidifying: by abrasive dust in the Rectorite batching input grinding machine after acidifying, particle fineness≤0.074 millimeter, the meal after abrasive dust is the Rectorite finished product after acidifying.
3, the half-finished production method of the Rectorite after acidifying: stir in the stirrer (1) first Rectorite after weathering input operated, then dilute sulphuric acid is slowly added in the Rectorite after weathering carry out acidification; (2), by the Rectorite after acidification, be Rectorite flap by twin rollers extruding, thickness≤3 millimeter of Rectorite flap; (3) Rectorite flap is transported to roasting in rotary type stoving oven, roasting time is 1 ~ 3 hour, maturing temperature controls at 250 ~ 350 DEG C, Rectorite flap water content≤5% after roasting, Rectorite flap after roasting is the Rectorite work in-process after acidifying, and PCm is weight percentage.
4, the batching of Rectorite flap is made up of following component by weight percentage: Rectorite mixture 75 ~ 95% and dilute sulphuric acid 5 ~ 25%.
5, the batching of Rectorite mixture is made up of following component by weight percentage: Rectorite 68 ~ 92%, attapulgite clay 7 ~ 30% and magnesium oxide 0.1 ~ 3%.
6, the batching of dilute sulphuric acid is made up of following component by weight percentage: concentration is the vitriol oil 1 ~ 25% and the water 75 ~ 99% of 98%, concentration be 98% vitriol oil per-cent be weight percentage.
The production method of the Rectorite after acidifying takes first acidifying to carry out compounding ingredient again, sulfuric acid and quick dissolved sodium silicate, polyvinyl alcohol, Vltra tears and sodium carbonate generation chemical reaction can be avoided, give full play to raw-material respective characteristic in batching, and obtain complementation, guarantee the Rectorite inner quality after acidifying.
According to the needs of quality product, adopt the Rectorite pH value after sodium carbonate adjustment acidifying, method is simple.
Rectorite after acidifying has good adsorptivity, oilness, thermostability, plasticity-and cohesiveness.
Rectorite after acidifying is applicable to the raw material of catalytic cracking agent carrier, coating, pottery and refractory materials.
