Agalmatolite slip fluidity is good, good penetrability, and agalmatolite has good thermostability and little hygral expansion, for this reason, can for the manufacture of size accurately, the product of Heat stability is good, body drying shrinks little, indeformable, burn till crack little, firing whiteness 90～96%, refractoriness >=1700 DEG C, insulation, heat insulating ability is good, and stable chemical performance, only has at high temperature and could be decomposed by sulfuric acid, the present invention selects the agalmatolite after pulverizing, particle fineness≤0.5 millimeter of agalmatolite.
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, and the present invention selects particle fineness≤5 millimeter of attapulgite clay.
Magnesium oxide has the general character of basic oxide, belongs to gelling material, can improve the colloidal property of agalmatolite.
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 agalmatolite pH value after acidifying.
The present invention is achieved by following technical proposals:
1, the batching of the agalmatolite after acidifying is made up of following component by weight percentage: agalmatolite 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 agalmatolite after acidifying: by abrasive dust in the agalmatolite batching input grinding machine after acidifying, particle fineness≤0.074 millimeter, the meal after abrasive dust is the agalmatolite finished product after acidifying.
3, the half-finished production method of the agalmatolite after acidifying: stir in the stirrer (1) input of the batching of agalmatolite mixture having been turned round, then dilute sulphuric acid is slowly added and carries out acidification in agalmatolite mixture; (2) by the agalmatolite mixture after acidification, push as agalmatolite flap thickness≤3 millimeter of agalmatolite flap by twin rollers; (3) agalmatolite flap is transported to roasting in rotary type stoving oven, roasting time is 1～3 hour, maturing temperature is controlled at 300～400 DEG C, agalmatolite flap water content≤2% after roasting, agalmatolite flap after roasting is the agalmatolite work in-process after acidifying, and PCm is weight percentage.
4, the batching of agalmatolite flap is made up of following component by weight percentage: agalmatolite mixture 75～95% and dilute sulphuric acid 5～25%.
5, the batching of agalmatolite mixture is made up of following component by weight percentage: agalmatolite 68～92%, attapulgite clay 5～30% 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 agalmatolite 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 agalmatolite inner quality after acidifying.
According to the needs of quality product, adopt sodium carbonate to adjust the agalmatolite pH value after acidifying, method is simple.
