Description

Illite clay after sodium
Technical field
The present invention relates to sodium process, be specifically related to the illite clay after a kind of sodium.
Background technology
Illite is that common one is glued the weathering of native ore deposit thing ﹐ Chang Youbai cloud female ﹑ potassium felspar sand and formed, and to originate in pelyte ﹐ or formed by other mineral alterations.It is often the middle transition mineral forming other clay minerals.Pure illite clay be Bai Se ﹐ but normal because of impurity the brown isochrome of Ran Cheng Huang ﹑ Lv ﹑, impure more gray or black earthy, property is crisp, frangible, quality is fine and smooth, smooth, hardness is little, be long placed in water and do not expand and loosely have research of chaotic phenomenon.
In illite clay mining area, usage mining machine carries out mechanical mining illite clay raw ore, excavate out be a kind of compact mass illite clay raw ore, the volume of illite clay raw ore is larger, sodium process can not be directly used in, normal employing pulverizer is broken for tiny particle and carries out sodium process, is easy to the crystalline structure destroying illite clay.
Do not carry out follow-up complementary modification after sodium process, the quality of illite clay product can not be improved comprehensively.
Summary of the invention
The object of the invention is to overcome weak point in prior art, the illite clay after a kind of sodium is provided.
Illite clay batching after sodium is made up of illite clay, magnesium oxide, sodium carbonate, quick dissolved sodium silicate, polyvinyl alcohol, Vltra tears and sodium acid pyrophosphate.
The production method of the illite clay after sodium: by abrasive dust in the illite clay batching input grinding machine after sodium, the meal after abrasive dust is the illite clay after sodium.
Illite clay has rich potassium, high alumina, low iron and superior chemistry, the physicals such as smooth, bright, fine and smooth, heat-resisting, illite clay particle fineness≤0.5 millimeter that the present invention selects.
Magnesium oxide has the general character of basic oxide, belongs to gelling material, can improve the colloidal property of illite clay.
Sodium carbonate has the general character and the thermostability of salt, soluble in water, and its aqueous solution, in alkalescence, is the main raw material of sodium in the present invention.
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 acid pyrophosphate is a kind of white powder, and relative density 1.86 is water-soluble, and the pH value of 1% aqueous solution is 3.5 ~ 4.5, for adjusting the illite clay pH value after sodium.
The present invention is achieved by following technical proposals:
1, the illite clay batching after sodium is made up of following component by weight percentage: illite clay flap 90 ~ 98%, quick dissolved sodium silicate 0.1 ~ 5%, polyvinyl alcohol 0.1 ~ 5%, Vltra tears 0.01 ~ 3% and sodium acid pyrophosphate 0 ~ 5%.
The production method of the illite clay 2, after sodium: by abrasive dust in the illite clay batching input grinding machine after sodium, particle fineness≤0.074 millimeter, the meal after abrasive dust is the illite clay after sodium.
3, the production method of illite clay flap: (1) by illite clay mixture input fermentation vat, more slowly added in illite clay mixture by water and soak sodium, sodium soak time is 24 ~ 72 hours; (2) take out the illite clay mixture after soaking, stir in input biaxial rneader, input after stirring in extrusion machine and be extruded into illite clay flap, illite clay thickness of flap≤3 millimeter; (3) be transported in rotary type stoving oven by illite clay flap and dry, it is 1 ~ 3 hour that drying time controls, and bake out temperature controls at 80 ~ 100 DEG C, and the illite clay flap water content after oven dry is 10 ~ 15%, and PCm is weight percentage.
4, the batching of illite clay flap is made up of following component by weight percentage: illite clay mixture 65 ~ 85% and water 15 ~ 35%.
5, the production method of illite clay mixture: stir in the batching of illite clay mixture input stirrer is illite clay mixture after stirring.
6, the batching of illite clay mixture is made up of following component by weight percentage: the illite clay 92 ~ 98% after weathering, magnesium oxide 0.5 ~ 5% and sodium carbonate 0.5 ~ 5%.
7, illite clay raw ore needs the time weathering more than two winters, illite clay after being the weathering of fine particle from the raw ore disintegration of large block compact, pick obvious visible barren rock block, vegetable fibre and other earth impurity, illite clay particle fineness≤5 millimeter after weathering.
The production method of the illite clay after sodium takes first sodium to carry out compounding ingredient again, sodium carbonate and quick dissolved sodium silicate, polyvinyl alcohol and Vltra tears generation chemical reaction can be avoided, give full play to raw-material respective characteristic in batching, and obtain complementation, guarantee the illite clay inner quality after sodium.
According to the needs of quality product, adopt the illite clay pH value after sodium acid pyrophosphate adjustment sodium.
Illite clay after sodium can improve the water-intake rate of illite clay, colloid index, expansion multiple, colloid viscosity, cation exchange capacity, dispersiveness in water medium and suspensibility.
Illite clay after sodium has the high feature of good thixotropy, oilness, thermostability, higher plasticity-, cohesiveness, hot green tensile strength and dry compression.
Illite clay after sodium is applicable to produce coating, filler, Ceramic fitting, makeup, soil adjusting agent, fodder additives, skeleton batching, cement ingredient, the removing pollutant of nuclear industry, environment protection and fire-fighting quipment.
