Abstract
The present invention discloses light stuffing of environment protection porcelain, which is prepared from the constituents by the weight percentage: 50 to 85% of clay and 15 to 50% of coal powder. Because the light stuffing is prepared by firing raw materials of clay and coal powder of which the storage is rich, the prices are low and the sources are wide, the light stuffing has the physical and chemical performance such as the same heat shock performance and moist adsorption capability as light porcelain stuffing prepared from high magnesium, wood dust or resin, and stone powder, better acid and alkali resistance, higher pressure resistance, light specific weight, convenient cut, etc.; meanwhile, the raw materials of clay and coal powder has the advantages of wide source, low price, short firing process time and low firing temperature; consequently, the light stuffing can reduce production cost, shorten a preparation period, improve preparation efficiency, fully use waste and old materials, save resource and protect an environment. The light stuffing is the novel light stuffing of environment protection porcelain, and can be widely suitable for chemical industry, metallurgy industry, coking industry, environmental protection industry, medicine industry, etc.
Description
Technical field
The present invention relates to a kind of filler, especially a kind of light environment protection porcelain filling.
Background technology
At present, in the reaction tower of chemical industry and metallurgy industry, in the washing desulphurization tower of coke gas industry, in the distillation water tower of Treatment of Industrial Water filtration tank and pharmaceutical industries, a large amount of fillers of demand all, and the filler of filling should have acid-fast alkali-proof, resistance to thermal shocks, moistening adsorptive power is arranged, light specific gravity again can resistance to compression etc. performance, these fillers can be used clay material, metallic substance, timber and plastics are made, and the filler made from clay material at present not only has certain comprehensive physical and chemical performance, and it is with respect to using metallic substance, timber and plastics are made, it is lower also to have its manufacturing cost, the characteristics that work-ing life is long, thereby the applying filler made from clay material is wider, especially along with developing rapidly with the light china filler of making through the clay material (potter's clay or china clay) after the activation treatment, the comprehensive physical and chemical performance of its filler increases, also has light specific gravity, characteristics easy to install, therefore the use of its light china filler is more suitable for user's requirement, market also constantly increases, these light china fillers are main raw with high attaclay and pore-forming material (as wood chip or resin etc.) mostly at present, adding an amount of extrusion high-temperature firings such as rock dust again forms, though it has higher resistance to thermal shocks its light china filler, moistening absorption ability and certain acid-fast alkali-proof, the characteristics of ultimate compression strength and light specific gravity, but it also has following weak point: the firstth,, because of the two aluminium amounts of trioxygen-containingization in the high attaclay lower, thereby its light china filler ultimate compression strength is not high, be that trioxygen-containingization two iron are higher in the high magnalium matter clay again, its light china filler acid-fast alkali-proof instability; The secondth,, the used material cost of its high attaclay is higher relatively, because high attaclay raw-material storing amount is less relatively, the place of production distributes also not too equal, thereby its cost of material is higher, even also the phenomenon that supply falls short of demand may appear, be pore-forming material resin raw material price height again, if need up to 20-30% with its add-on ratio of wood chip, consumption wood chip amount is big, some difficulty of local purchase, for this reason or the haul distance buying of leaving away, increase production cost, or fall trees in the locality and to produce wood chip, the waste forest reserves are unfavorable for environment protection; The 3rd is, with its firing time of light china filler that above-mentioned high attaclay and starting material such as wood chip or resin are made want more than 60 hours, firing temperature is up to 1300 ℃, therefore needs to consume a large amount of fuel, increased production cost, the production cycle is long.Comprehensively above-mentioned; with high attaclay and wood chip or resin is the light china filler that main raw material etc. is made; though it has the certain physics chemical performance; but its ultimate compression strength is lower; acid-fast alkali-proof instability, manufacturing cost are higher relatively, and the waste forest reserves; be unfavorable for environment protection, influence economic benefit of enterprises and social benefit.
Technology contents
Lower at light china filler ultimate compression strength in the above-mentioned prior art; the acid-fast alkali-proof instability; production cost is higher; waste resource and the problem that is unfavorable for environment protection; a kind of not only have identical resistance to thermal shocks and the moistening absorption ability of providing is provided, the physical and chemical performance of the stable and higher ultimate compression strength of better acid-fast alkali-proof is arranged again simultaneously, and its production cost is low; can make full use of waste materials, economize on resources and help the light environment protection porcelain filling of environment protection.
The object of the present invention is achieved like this, it adopts storage capacity abundant, the place of production is many, the a large amount of waste and old flyash in widespread clay and fuel-burning power plant is the raw material mixed preparing, adopting wet method to fire forms, the component of its light environment protection porcelain filling comprises clay, flyash, the weight percent of its component is: clay 50-85%, flyash 15-50%, the weight percent that described light environment protection porcelain filling Chemical Composition is formed is: silicon-dioxide 65-90%, aluminium sesquioxide 6-12%, ferric oxide≤2%, magnesium oxide≤21%, sodium oxide≤0.1%, calcium oxide≤2.5%, potassium oxide≤1.8%, titanium dioxide≤0.33%.
Described clay is unselected clay (also being commonly called as watt mud or white clay), and abundant at most of local storage capacitys such as China Shandong, Shanxi, Henan, Sichuan, Hunan, Jiangxi, price is also low, producing clay with its Jiangxi is example, average content is: silicon-dioxide 〉=69.77%, aluminium sesquioxide 〉=3.29%, ferric oxide≤1.21%, magnesium oxide≤18.93%, sodium oxide≤0.04%, calcium oxide≤0.92%, potassium oxide≤0.07%, titanium dioxide≤0.19%, burning decrement 5.58%.
Described flyash is the fuel-burning power plant waste materials, and its output is big, and price is low, with Pingxiang, Jiangxi Province power plant fly ash is example, average content is: silica volume 〉=53.3%, aluminium sesquioxide 〉=19.6%, impurity average content: ferric oxide≤2.41%, magnesium oxide≤1.79%, sodium oxide≤0.08%, calcium oxide≤3.41%, potassium oxide≤0.54%, titanium dioxide≤1%, burning decrement 17.86%.
The manufacture method step of light environment protection porcelain filling of the present invention is:
1, press clay 50-85%, the proportioning of flyash 15-50% joined in the ball mill evenly mixed grind 1 hour with its raw material,
2, the compound after the mixed grind magnetizes processing, removes the ferric oxide in it,
3, in reciprocating sieve, sieve after, send into and press into the work in-process filler in the slip drying press,
4, above-mentioned work in-process filler is joined carry out wet processing in the vacuum pugmill after, be input to extrusion moulding in the mould,
5, the filler with moulding is sent in the drying room, carry out skin drying with liquefied gas or Sweet natural gas type of heating rapid heating, when being heated to 300 ℃ rapidly, be incubated 2 hours and carry out low temperature dehumidification, when continuing to be heated to 600-700 ℃, be incubated 4 hours and carry out calcination, reheat is during to 900-1000 ℃, being incubated 4 hours reduces
6, then cooling to normal temperature with the furnace comes out of the stove.
Light environment protection porcelain filling of the present invention after testing after, the every technical indicator of its physical and chemical performance is:
Ultimate compression strength: 8-14MPa water-intake rate: 18-35%
