Abstract
The invention discloses a kind of titanium gypsums and its preparation process using alkaline residue preparation, titanium gypsum is prepared by mass percentage by the following raw material: alkaline residue 40-50%, titanium gypsum 50-60%, after alkaline residue, titanium gypsum are weighed according to the ratio first, stirring evenly molding by mechanical mixture is 1-10mm granule, activates and solidifies 1-7 days under normal temperature conditions, carries out stacking activation, make the weight percent of the Free water in product in 6-10% to get to titanium gypsum product.Other gypsum such as natural dihydrate gypsum can directly be substituted for producing cement products in cement.Product of the present invention, which solves original state titanium gypsum production cement, will affect cement quality, concrete compatibility workability, and clinker dosage can be reduced, the performances such as cement specific surface area and strength of cement are improved, and improve cement unit-hour output and reduce manufacture of cement cost.Solid waste resource recovery comprehensive utilization new technology is realized, protects environment not by the good method of secondary pollution.
Description
Technical field
The invention belongs to field of cement production, and in particular to a kind of titanium gypsum and its preparation process using alkaline residue preparation.
Background technique
Titanium gypsum is a kind of waste residue generated after producing titanium dioxide with titanium ore, and water content is 40% or so, pH value ratio
It is lower, also contain a little harmful and noxious substance.Therefore, development and utilization are very difficult, and cannot be directly used to manufacture of cement, because
It has a certain impact to cement quality, especially directly affects cement concrete compatibility normal work degree.Currently, big portion, China
Divide waste residue titanium gypsum still to be stacked or filled with a large amount of farmlands, has effectively caused to secondary environmental pollution, also had a little enterprise that will give up
The problem of slag titanium gypsum is handled through reheating, this method processing, there is also some pairs of secondary environmental pollutions, this is also not
Best method.
Summary of the invention
Goal of the invention: the purpose of the present invention is to solve the above problems, provide a kind of titanium gypsum prepared using alkaline residue
And its preparation process, the exploitation usage amount of the natural gypsum can be reduced, protect environment, saved the processing that farmland is stacked or filled
Titanium gypsum prepared by the present invention is used in manufacture of cement by expense, and hydrated cementitious intensity and stable cement slurry can be improved
It can effect.
Technical solution: a kind of titanium gypsum prepared using alkaline residue of the present invention, by mass percentage by the following raw material
It is prepared: alkaline residue 40-50%, titanium gypsum 50-60%.
The present invention also provides the preparation processes of titanium gypsum, after alkaline residue, titanium gypsum are weighed according to the ratio first, pass through machinery
It is mixed evenly and is shaped to 1-10mm granule, activate under normal temperature conditions and solidify 1-7 days, carry out stacking activation, make to produce
The weight percent of Free water in product arrives titanium gypsum product in 6-10%.
The present invention produces the industrial caustic that industrial soda is then discharged with chemical plant, containing a small amount of alkaline matter, to activate
Titanium gypsum, to change the mineral composition in original state titanium gypsum, and form new chemical component, make different types of object
Matter is close to each other as far as possible, is combined into aquo-compound with water as far as possible.The proper property according to aquation and crystallization is connect, these are mixed
The substance of conjunction, the titanium gypsum through activating form new crystallization hyrate.Crystallize the formation of hyrate, on the one hand, reduce mixture
In intrinsic Free water, mitigate Free water in material and negatively affected caused by technique；On the other hand, the titanium stone of this activation
Cream is used in manufacture of cement, plays induction hydrated cementitious and crystallization, this just can accelerate hydrated cementitious and suitably change
It is harmful to the stable mineral formation of cement performance.To make the titanium gypsum of activation, for will not influence cement in manufacture of cement
Quality, and improve cement concrete compatibility and be in normal working condition, and improve hydrated cementitious intensity and stabilization
Properties of Portland cement effect.
The utility model has the advantages that
1. product of the present invention technological operation is simple, as long as industrial residue is stirred by different ratio by mechanical mixture
Even, activation is stacked in molding, and curing conservation under normal temperature conditions, makes the Free water in product in 6-10%, so that it may directly mix
Product is produced into cement, without any in heating process treatment, secondary dirt is not present without useless ash discharge in no waste water, no waste residue
Environment is contaminated, is a kind of energy saving good product, turns waste into wealth, while having saved the expense that a large amount of soils are stacked or filled, and
Protect environment not by secondary pollution.
2. product of the present invention raw materials are 100% waste residue entirely, because waste residue titanium gypsum is in acid, and alkaline residue is to be in
Basic species play the role of the effect of acid-base neutralization so the two combines, and play protection environment no longer by secondary pollution.
Meanwhile the chemical component in original state titanium gypsum is improved, so that titanium gypsum is formd new hydrated minerals composition, and in manufacture of cement
In form high degree of dispersion hydrated minerals small crystals again.Hydrated cementitious speed is accelerated, hydrated cementitious crystalline mineral is can induce and exists
There is new development on the basis of these small crystals.Thus, it avoids in coagulating cement native produce, because certain hydrated minerals are to cement water
Change the mass effect negatively affected caused by intensity and concrete compatibility workability.
3. product of the present invention, can other gypsum such as direct 100% substitution natural dihydrate gypsum be not required to for being produced in cement
Add the techniques such as any crushing mechanism.
4. product of the present invention can play grinding-aid effect in manufacture of cement, it is left that mill hourly output 5-10% can be improved
It is right.
5. product of the present invention can accelerate the hydration reaction of cement in cement, the surface area 30-50% of cement can be improved
m2/ kg or so can also improve strength of cement 2-4mpa or so.
6. product of the present invention, can be in manufacture of cement, can be less with clinker 3-5% or so, cement quality is not reduced, and can save
Cement cost 5-10 member per ton or so.
Product of the present invention plays the performance for improving cement concrete, compatibility performance is good, the slump in cement products
Greatly, resisting carbonization is strong, resists durable and wear-resisting property strong, peels phenomenon in large-area concrete construction without blistering and surface,
The performances such as concrete quality can be improved.
