Abstract

The invention discloses acidified rectorite clay, and the key points of the technical scheme are that: acidified rectorite clay ingredients comprise rectorite clay, magnesium oxide, sulfuric acid, attapulgite clay, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate. A production method of the acidified rectorite clay is as follows: acidified rectorite clay ingredients are transported into a mill for powder milling, and the milled powder is the acidified rectorite clay. By first acidification and then ingredient compounding, chemical reaction of the sulfuric acid and the instant sodium silicate, the polyvinyl alcohol, the hydroxypropyl methyl cellulose and the sodium carbonate can be avoided,and respective characteristics of raw materials in the ingredients can be fully played, and are complementary, so that the inherent quality of the acidified rectorite clay can be ensured. The acidified rectorite clay has the characteristics of good adsorption, lubricity, thermostability, plasticity and adhesion, and is applicable to raw materials of catalytic cracking agent carriers, coatings, ceramics and refractory materials.

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 is a kind of have special construction, comparatively rare clay of laminar silicate mineral.Rectorite leng is met water electrode and is easily disperseed, film forming is smooth, rectorite leng and other clay pit associations in most of place of production, grade is lower, oneself finds rectorite leng mineral and Rectorite rock China in many places, but it is reported the rectorite leng of finding in Permian System In Zhongxiang, hubei rock have fairly large, 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 can see lath-shaped, fiber needle-like crystal, main component is hydrous alumino silicates, many and clay pit association, mineralogical composition is called Rectorite taking rectorite leng as the clay of leading or contain certain proportion rectorite leng, 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, fibrous or fiber collection shape.Attapulgite clay has unique dispersion, high temperature resistant, the anti-good colloidal property such as saline and alkaline and higher adsorptive power, 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.
It is 98% the vitriol oil that sulfuric acid is selected concentration.
Quick dissolved sodium silicate is white pulverulent 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, particulate state, Powdered three kinds; Nonpoisonous and tasteless, particulate state 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, polymerizability, cohesiveness and water-retentivity.
Vltra tears has thickening capabilities, salt discharge, pH stability, water-retentivity, dimensional stability, good film-forming properties and the feature such as resistance to enzyme, 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 batching of the Rectorite after acidifying is made up of following component by weight percentage: Rectorite work in-process 90~98%, quick dissolved sodium silicate 0.1~5%, polyvinyl alcohol 0.1~5%, Vltra tears 0.01~3% and sodium carbonate 0~3% after acidifying.
2, the production method of the Rectorite 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 having been turned round, then dilute sulphuric acid is slowly added and carries out acidification in the Rectorite after weathering; (2) by the Rectorite after acidification, push as Rectorite flap thickness≤3 millimeter of Rectorite flap by twin rollers; (3) Rectorite flap is transported to roasting in rotary type stoving oven, roasting time is 1~3 hour, maturing temperature is controlled 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: the vitriol oil 1~25% that concentration is 98% and water 75~99%, the vitriol oil per-cent that concentration is 98% is weight percentage.
The production method of the Rectorite after acidifying takes first acidifying to carry out compounding ingredient again, can avoid sulfuric acid and quick dissolved sodium silicate, polyvinyl alcohol, Vltra tears and sodium carbonate generation chemical reaction, give full play to raw-material characteristic separately in batching, and obtain complementation, guarantee the Rectorite inner quality after acidifying.
According to the needs of quality product, adopt sodium carbonate to adjust the Rectorite pH value after 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.
