Abstract
The present invention discloses ceramic powder and a preparation method thereof. According to the method, vanadium extraction tailings or pyrite cinders and chromium slag industrial waste are used, additives are added or not as raw materials, conventional processes and equipment of the field are used, and the materials are very cheap and readily available, so that cost is greatly reduced. The ceramic powder is used in manufacturing of ceramic products, and also widely used in colorants, plastic and rubber fillers and paint.
Description
Invent described field
The present invention relates to black ceramic dusty material。More particularly, it relates to the method producing black ceramic dusty material with tailings in vanadium extraction or pyrite cinder and chromium slag industrial waste。The invention still further relates to the ceramic powders produced in aforementioned manners。
Background of invention
Produce daily conventional ceramic from natural ceramic material and have the history of several thousand, but produce, with industry products material, the thing that the pottery with special nature is only decades。For the needs of satisfied society, people's willingness is devoted to the ceramic material that exploitation is new。At present, being added in ceramic material to manufacture the black pigment of ceramic body is prepare with metal-oxides such as ferrum, manganese, chromium, cobalt, nickel, the filler such as plastics, rubber, and generally with stone powder, calcium carbonate, these industrial products prices are significantly high。So that being difficult to even not be likely to production black ceramic goods in a large number。Therefore, adopt low cost to produce black ceramic dusty material in a large number, be always up the brainstrust research of the art and the problem of exploration for many years。
Present inventors have surprisingly found that, tailings in vanadium extraction or pyrite cinder and chromium slag industrial waste can have important use value on the one hand at this。
Goal of the invention
An object of the present invention is to provide a kind of tailings in vanadium extraction with current bulk deposition or pyrite cinder and chromium slag industrial waste, adds or is added without the additive method to manufacture black ceramic powder。The two of the purpose of the present invention are to provide and a kind of produce black ceramic dusty material with containing the tailings in vanadium extraction that Ti, V, Cr, Mn, Fe sum is more than 20 or Ti, V, Cr, Mn sum is more than 3 (this specification is all in oxide weight %) or pyrite cinder and chromium slag。The three of the purpose of the present invention are to provide with this ceramic powders as black colorant, black plastic, the filler of rubber, coating。
The composition of invention
The most important particularity of method of the present invention is in that, uses raw material very cheap, is easily obtainable。According to the present invention, select and contain the tailings in vanadium extraction or pyrite cinder and chromium slag industrial waste that titanium, vanadium, chromium, manganese sum are more than 3 or titanium, vanadium, chromium, manganese, ferrum sum are more than 20, add additive but it also may being added without additive is raw material。Except the feature of raw material, the common process of this area and equipment can be applied。Additive described in the present invention refers to various unselected clay, china clay, porcelain stone, potter's clay, fire clay, shale, gangue, red mud, boron mud, titanium slag, lemon dregs, furfural dregs and methylcellulose, starch, Radix Acaciae senegalis, waterglass or certain industrial residue, natural crystal, binding agent。
Tailings in vanadium extraction described in the present invention and pyrite cinder and chromium slag industrial waste, all there are bulk deposition in industrial enterprise a lot of at present。These industrial wastes piled up result in environmental problem, and they not only cannot function as commodity selling, and to spend a lot of money to go to administer。Technical process for producing the ceramic powder material of the present invention can the technique of any routine, for instance can make:
1. by above-mentioned industrial waste co-grinding to less than 20 orders, being generally 100 to 400 orders。
2. by above-mentioned industrial waste in common kiln or rotary kiln through more than 800 DEG C。It is generally 1000 to 1400 DEG C to calcine 1 minute, general 160 minutes, is crushed to after coming out of the stove less than 20 orders, is generally 100 to 400 orders。
Above-mentioned industrial waste is crushed to less than 20 orders, it is generally 100 to 400 orders, add (also can be added without) additive with powdery, bulk or pulpous state in common kiln or in rotary kiln warp more than 800 DEG C, it is generally 1000 to 1400 DEG C to calcine more than 1 minute, it is generally 1 to 60 minute, it is crushed to after coming out of the stove less than 20 orders, is generally 100 to 400 orders。
Ceramic powders of the present invention also has a variety of purposes except directly manufacturing ceramic, for instance:
1. the general metal-oxide such as white carbon black or Fe, Mn, Cr, Co, Ni is as the black colorant used under room temperature and black enamel, enamel coloring agent。The blackness of ceramic powders of the present invention, close to carbon black, can be used as the black colorant and glaze, the enamel coloring agent that use under room temperature, with low cost。
2. general stone powder, calcium carbonate etc. are as the filler of plastics, rubber etc., and black plastic, rubber separately add carbon black as coloring agent, and ceramic powders of the present invention can replace the filler in plastics, rubber and carbon black simultaneously。
3. general kiln inwall is refractory brick, and in kiln, heat is taken away by thermal current in a large number。Ceramic powder coating of the present invention heat absorption, radiance are better than common refractory brick, surface layer as kiln inwall, firebreak can heat in more absorption thermal current, and pass to heating target in the form of radiation, make the heat that thermal current is taken away reduce accordingly, thus saving the energy。
Tailings in vanadium extraction is so to produce: vanadium titano-magnetite ore deposit is smelting obtains vanadium-bearing hot metal, vanadium-bearing hot metal obtains vanadium slag through blowing, vanadium slag adds adjuvant and carries out roasting, roasting material is carried out leaching vanadium extraction, remaining residue is tailings in vanadium extraction, being better than the different difference with production technology in v-ti magnetite orefield, produced tailings in vanadium extraction chemical composition also has some difference, the chemical composition of general tailings in vanadium extraction to be (%)
The explanation of most preferred embodiment
Example 1: tailings in vanadium extraction is crushed to 160 orders, namely becomes ceramic powders。
Example 2: directly being calcined 5 minutes through 1250 DEG C by tailings in vanadium extraction, namely be crushed to 160 orders after taking-up becomes ceramic powders。
Example 3: tailings in vanadium extraction is crushed to 160 orders, adding water and making thickness is that about 15mm is block, puts into electric furnace after drying and calcines 5 minutes through 1300 DEG C, and namely be crushed to 160 orders after taking-up becomes ceramic powders。
Example 4: by pyrite cinder dry pulverization process to 160 orders, takes 2 parts, and chromic slag wet method is crushed to 140 orders, takes 1 part (being converted into dry slag weight) and uses blender mix homogeneously, makes the mud bar of non-10mm so far with extruding machine。Fracture into length 15 to 20mm cylindrical pellet after drying, it is put in rotary kiln continuously, calcine 5 to 10 minutes through 1220 DEG C。Ceramic aggregate will be obtained be crushed to 160 orders and namely become ceramic powders。
