Abstract
Colour cement produced by vertical kiln.The invention belongs to a kind of production method of colored cement.Adopt shaft kiln directly to calcine, make colored grog, in raw material, add the metal oxide and the corresponding industrial residue thereof of an amount of chromium or manganese or cobalt respectively and make tinting material, adopt to add CaF
2With BaSO
4As composite mineralizer, mix setting accelerator NaCl, CaCl
2Make admixture with stearic acid or hide glue water.Advantages such as this law has less investment, the cycle of founding the factory is short, raw material sources are wide, firing temperature is low, and product colourity is even, durable, and is bright in luster.Make tinting material with industrial residue, help environment protection.
Description
The invention belongs to a kind of production method of colored cement.
In the prior art, the production method of colored cement is divided into following three kinds by its technological principle: (1) adds pigment in white cement clinker; (2) in ordinary portland cement clinker, add pigment and make the darker colored cement of color; (3) be base-material with the white cement raw material, adopt rotary kiln to carry out high-temperature calcination.In these production methods, preceding two kinds advantage is that cement toning is convenient, is easy to on-the-spot allotment construction, but will guarantee the use properties of cement, to mixing dispersing of pigments in the cement, stability, anti-strong basicity etc. harsh requirement is arranged all.Then a kind of production method that adopts rotary kiln, founds the factory that investment is many, floor space is big at complex process, and the production cycle is long, and firing temperature height (flame temperature is more than 1700 ℃) is strict to material purity, and is difficult satisfied in the production.International online retrieval is the result show, still useless shaft kiln prepares the production method of colored cement in the prior art.
The object of the present invention is to provide a kind of employing shaft kiln directly to calcine, make the production technique that colored grog is produced colored cement, produce special cement for existing shaft kiln cement plant and start new approach.
Task of the present invention is finished as follows:
1. the selection of starting material and fuel: in order suitably to limit unwanted oxide compound, guarantee the required dyeing of oxide compound in grog, the reply starting material are done necessary selection and control, and the specification of used crude fuel is:
Wingdale: CaO＞54%, Fe
2O
3＜0.4%, MgO＜0.5%
Carclazyte: SiO
2＞68%, Al
2O
3＞12%, Fe
2O
3＜1.7%
Fluorite: CaF＞50%
Barite: BaSO
4＞70%
Tinting material: chromic oxide (purity 30～90%, add-on 0.3～2.5%)
Cobalt oxide (purity 30～90%, add-on 0.3～2.5%)
Ferro-cobalt ore deposit (containing cobalt 20～40%, add-on 0.3～3%)
Granulation blast furnace manganese mud, manganese oxide (containing manganese 8～16%, add-on 6～8%)
Gypsum: white plaster of paris SO
3More than＞38%
Fuel: hard coal or bituminous coal (iron-holder in the coal ash＜6%)
2. the prescription of raw material and Chemical Composition: see Table 1
3. the production of grog: the raw material that prepare are gone into mill, and grinding to 4900 hole sizer tails over below 10%.Add hard coal or bituminous coal behind the grinding, fully mix adds the water balling-up, and amount of water is 12～14% of a raw material weight, goes into the kiln oxidation then and burns till, at 1200～1450 ℃ temperature lower calcinations after 20～40 minutes.Through going into the kiln air cooling, look metal oxide that when batching add or industrial residue and be fired into the grog of different colours.As add an amount of chromic oxide or chromite or contain the industrial residue of chromium, can burn till green grog; Manganese oxide or manganiferous industrial residue mix raw material, can burn till blue grog; If the industrial residue that adds the oxide compound of cobalt or contain cobalt then can burn till red grog, these grog colors evenly and delicious.
4. mix the grinding of admixture and grog:
In grog, add 3～6% white natural dihydrate gypsum, 0.03～0.1% NaCl, CaCl
2, 0.01% stearic acid is or/and hide glue water, with the bright-coloured and solution that the keeps product color problem of saltouing.Grog and admixture were poured the ball mill grinding into 25～40 minutes after weighing in proportion and cooperating, and were milled to that the 0.08mm square hole sieve tails over 8%, specific area 3500～4000, promptly made corresponding colored cement.
The method for preparing colored cement with shaft kiln provided by the present invention, its advantage is that found the factory less investment, floor space is little, the cycle of founding the factory is short, can relax requirement to material purity, the content of ferric oxide in the raw material particularly, can be loosened to 3%, many like this raw materials that can not be used to produce white cement can be fired colored grog with shaft kiln.Owing to added tinting material in the raw material, make raw material have certain mineralization, can reduce firing temperature, realize easy fired, help the formation of clinker mineral, help improving the physical and mechanical property of colored cement grog.The colourity of product is even, and is durable, bright in luster.The present invention makes tinting material to utilizing refuse with industrial residue, and pollution abatement protects environment to have positive meaning.Also produce special cement and started a new way for existing shaft kiln cement plant.
