Abstract
The invention discloses novel titanium gypsum manufactured with alkaline residues and a manufacturing technology thereof. The novel titanium gypsum is manufactured with, by mass, 40-50% of the alkaline residues and 50-60% of titanium gypsum. The manufacturing technology includes the steps that the alkaline residues and the titanium gypsum are weighed by the ratio and mechanically mixed and evenly stirred to form particles with the particle size of 1-10 mm, the particles are activated at the normal temperature and cured for 1-7 days to be activated in a stacked mode, and the weight percent of free water in the mixture is 6-10% to obtain the novel titanium gypsum. The novel titanium gypsum can replace other kinds of gypsum like natural dihydrate gypsum to be used in cement for producing cement products. The novel titanium gypsum solves the problems that if original-state titanium gypsum is used for producing the cement, cement quality and the concrete compatibility working degree will be affected, reduces usage of clinker, improves the performance such as the cement specific surface area and cement strength, improves the machine-hour yield of the cement and reduces the production cost of the cement. The good method of protecting the environment against secondary pollution by using the new technology of resourcezation comprehensive utilization of solid waste is achieved.
Description
Technical field
The invention belongs to field of cement production, be specifically related to a kind of utilize alkaline residue to prepare Novel Titanium gypsum and preparation technology.
Background technology
Titanium gypsum is a kind of waste residue produced after producing titanium dioxide with titanium ore, and water content is about 40%, and pH value is lower, also containing a little harmful and noxious substance.Therefore, develop very difficult, can not manufacture of cement be directly used in again, because have a certain impact to cement quality, particularly directly affect the normal workability of cement concrete consistency.At present, China's major part waste residue titanium gypsum is still stacked or landfill with a large amount of farmland, seriously causes secondary environmental pollution, also a little enterprise is had by waste residue titanium gypsum through second-heating process, this method process, also there are some problems to secondary environmental pollution, this neither best method.
Summary of the invention
Goal of the invention: the object of the invention is to solve the problem; there is provided a kind of utilize alkaline residue to prepare Novel Titanium gypsum and preparation technology; the exploitation usage quantity of the plaster of paris can be decreased; protection of the environment; save the processing costs of farmland stacking or landfill; Novel Titanium gypsum the present invention prepared is used in manufacture of cement, can improve the properties of Portland cement effect of hydrated cementitious strength and stability.
Technical scheme: a kind of Novel Titanium gypsum utilizing alkaline residue to prepare of the present invention, is prepared from by following raw material: alkaline residue 40-50%, titanium gypsum 50-60% by mass percentage.
Present invention also offers the preparation technology of Novel Titanium gypsum, first after alkaline residue, titanium gypsum being weighed by proportioning, stirring shaping by mechanically mixing is 1-10mm granule, activate under normal temperature condition and solidify 1-7 days, carry out stacking to activate, make the weight percentage of the free water in product in 6-10%, namely obtain Novel Titanium gypsum product.
The industrial caustic that the present invention chemical plant manufacture alkali is then discharged, containing a small amount of alkaline matter, the Novel Titanium gypsum activated, thus the mineral composition changed in original state titanium gypsum, and define new chemical composition, make dissimilar material close to each other as much as possible, be combined into aquo compound with water as far as possible.Connect the proper property according to aquation and crystallization, the material of these mixing, through the Novel Titanium gypsum activated, form new crystal water compound.The formation of crystal water compound, on the one hand, reduces free water intrinsic in mixture, alleviates the negative impact that in material, free water causes technique; On the other hand, the Novel Titanium gypsum of this activation, uses in manufacture of cement, play induction hydrated cementitious and crystallization, this just can accelerate hydrated cementitious, can be harmful to the stable mineral formation of cement performance by appropriate change again.Thus make the Novel Titanium gypsum of activation, in manufacture of cement, can not cement quality be affected, and improve cement concrete consistency and be in normal working order, turn improve the properties of Portland cement effect of hydrated cementitious strength and stability.
Beneficial effect:
1. Product Process of the present invention is simple to operate; as long as industrial residue is stirred by mechanically mixing by different ratio; shaping; stack and activate; curing conservation is under normal temperature condition; make free water in product in 6-10%, just directly can mix in cement and produce product, without the need to any in heating process process; without waste water; without waste residue, without useless ash discharge, there is not secondary pollution environment; it is a kind of good product of save energy; turn waste into wealth, saved the expense of the stacking of a large amount of soils or landfill simultaneously, and protected environment not by secondary pollution.
2. product raw materials of the present invention is 100% waste residue entirely, because waste residue titanium gypsum is acid, and alkaline residue is in alkaline substance, so the two combines, plays the effect of acid-base neutralisation, serves protection of the environment no longer by the effect of secondary pollution.Meanwhile, improve the chemical composition in original state titanium gypsum, make Novel Titanium gypsum define new hydrated minerals composition, and in manufacture of cement, define again high dispersing hydrated minerals small-crystalline.Accelerate hydrated cementitious speed, hydrated cementitious crystalline mineral can be induced on these small-crystalline bases to have new development.Thus, avoid in coagulating cement native produce, because some hydrated minerals is to the mass effect of the negative impact that hydrated cementitious intensity and concrete consistency workability produce.
3. product of the present invention, direct 100% can substituting other gypsum such as natural dihydrate gypsum, for producing in cement, not needing to add the techniques such as any crushing mechanism.
4. product of the present invention, in manufacture of cement, can play grinding-aid effect, can improve mill hourly output about 5-10%.
5. product of the present invention, in cement, can accelerate the hydration reaction of cement, can improve the surface-area 30-50%m of cement
2about/kg, can also improve about strength of cement 2-4mpa.
6. product of the present invention, can in manufacture of cement, and can use grog about 3-5% less, cement quality does not reduce, about can saving cement cost 5-10 unit per ton.
Product of the present invention, in cement products, plays the performance improving cement concrete, consistency performance is good, and the slump is large, and resisting carbonization is strong, anti-durable strong with wear resisting property, without bubbling and surperficial decortication phenomenon in large-area concrete construction, can the performances such as concrete quality be improved.
