Description
Technical field
The present invention relates to building field, in particular it relates to a kind of accumulation of heat materials for wall.
Background technology
With the development of agricultural science and technology, heliogreenhouse has turned into the trend of agricultural development.The warming level of daylighting in greenhouse with
The accumulation of energy heat insulation effect of wall has a significant impact to the production potential in greenhouse afterwards.Current rear wall of greenhouse typically using concrete or
Add the temperature insulating materials such as polystyrene foam to be made, consume a large amount of building resources, but heat-accumulating and-keeping effect is poor.
Flyash is the solid particle that the ash content in coal is formed after the processes such as decomposition, sintering, melting and cooling, surface
It is spherical in shape, have the advantages that grain thin, light weight, specific surface area be big, water imbibition is strong, its chemical composition is much like with clay, main group
As silica, aluminum oxide and calcium oxide etc..Difference according to calcium content can be divided into high-calcium fly ass and bottom calcium fly ash.At present
The application of flyash is mainly in construction industry：(1) cement is produced using flyash.Application of the flyash in cement industry,
One admixture for being used as cement, two is to produce clinker as clay composition dispensing.Present pulverized fuel ash cement has turned into me
One of large cement kind of state five；(2) cement consumption can not only be reduced as concrete admixture by the use of flyash, aquation is reduced
Heat, but also concrete impermeability and resistance to corrosion can be improved；(3) can be with brickmaking product using flyash.In brickmaker
A certain amount of flyash is added during skill can to a certain extent improve the compression strength of coal-dust brick.
The chemical analysis of cinder is approached with flyash, mainly contains substantial amounts of siliceous vitreum (Al2O3.SiO2) and activity
Silica and a small amount of unburned carbon etc..Although SiO in cinder2Content is up to 21-61%, but because cinder is relatively coarse, activity
It is high without flyash, the SiO in vitreum2And Al2O3Dissolution is more difficult to, hydrated calcium silicate is also hardly formed and is produced intensity, therefore phase
Processing and utilization to cinder is more difficult, presently mainly using the loose and porous structure of cinder, uses it for Waste Water Treatment, moves
The aspects such as dynamic bed adsorption system, production hollow brick.
Carbide slag is that calcium carbide hydrolysis obtains the waste residue produced after acetylene gas, and main component is Ca (OH)2, containing micro carbon and
Sulphur impurity, there is micro- stink, and slag liquid pH value is 12 or so, thus often causes severe contamination to environment.The calcium carbide that China stacks every year
Slag has millions of tons, and only part is used to produce cement at present, separately there is a small amount of for producing calcium carbonate and calcium chloride and three-protection design.
In " ash-slag brick making method " that patent 97109103X is provided, flyash is 16-180 parts, and cement is 50-80 parts,
Rubble is 1150-1259 parts, need to be conserved 3-5 days, haves the shortcomings that the consumptions such as construction material cement, rubble are big in the method；Specially
The flyash brick free of calcining and steam curing that profit 2010190260972 is produced using CFBC Desulphurizations, its formula is CFBC Desulphurizations 57%, stove
Bottom ash 20%, cement 8%, quick lime 12%, gypsum 3%, then add the water of blending ingredients quality 12%-18%, one
Under constant-pressure it is compressing after through conserving to obtain flyash brick, its compression strength is up to 20MPa.Patent CN103496925A is disclosed
A kind of materials such as utilization flyash prepare the technology for heating wall, and the technology can play certain temperature raising and maintaining effect, but still need
Expend more construction material cement.
In sum, had in the prior art and made insulating wall material using coal ash for manufacturing, but obtained material is protected
Temp effect is bad or compression strength is not high, and still needs to expend more construction material such as cement etc. in preparation process, cost compared with
It is high.
The content of the invention
