Abstract

The invention discloses a kind of water-fast fluorgypsum mould to close, including following raw material: fluorgypsum 400 550 parts；250 300 parts of Gypsum Fibrosum；Breeze 100 250 parts；Cement 30 100 parts；Sulphate aluminium cement 50 100 parts；Water reducer 15 parts；Basic matterial 10 20 parts；Exciting agent 8 15 parts；Glass fibre 5 10 parts, component is poured into stirring container mix and blend 3 5min according to weight ratio, it is ready for suitable quantity of water, the component of mixing is poured into water stirring 30s, pouring the mixture into die for molding, quiet stop the demoulding after 10min, the mould obtained by covered rearing with plastic film closes 3 days and wet supports, the present invention solves the drawback that the most water-fast and intensity that fluorgypsum mould closes is low, it is provided that a kind of a large amount of process fluorgypsums and scientific utilization fluorgypsum technology.

Description

Water-fast fluorgypsum mould conjunction and preparation method thereof
Technical field
The invention belongs to solid waste comprehensive utilization of resources and the water-fast technical field of construction material, a kind of water-fast fluorgypsum Mould conjunction and preparation method thereof.
Background technology
Fluorgypsum is that sulphuric acid reacts, with fluorite, the waste residue produced, and acidity is very strong, and pH value is 3-4, belongs to the strongest the having of corrosivity Evil solid waste, utilization rate is the lowest, such stores up in a large number, and how both landed property resources, again polluted underground water source and environment pass through Research and develop effective technological means, solid waste fluorgypsum is turned waste into wealth, effectively utilizes, there is far-reaching economic and environment-friendly meaning.Another Aspect, plaster mold closes and has commercially developed 3-5, and prospect is pretty good, and added value is the highest, but standard is put into effect not yet, deadly defect Be completely exposed, hence it is evident that constrain development that plaster mold closes and market advances, it the most water-fast, intensity is low, long green hair three is the most fatal Wound, have impact on mould and closes the fast development of industry, and the price causing the homogeneity product between the dissatisfied of market and enterprise compares with, The generation of market demand new technique.
Summary of the invention
It is an object of the present invention to provide a kind of water-fast fluorgypsum mould conjunction and preparation method thereof, make full use of discarded fluorgypsum, protect Protect can not regenerated resources, preserve the ecological environment, solve semi-hydrated gypsum mould close exist the most water-fast, intensity is low, the fraud of the easy accumulation of salt in the surface soil Disease, promotes plaster mold to close the development of industry, meets the demand that water-proof gypsum mould is closed by market.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:
Water-fast fluorgypsum mould closes, including following raw material:
Fluorgypsum is in Fluohydric acid. enterprise production process, sulphuric acid and fluorite react the waste residue produced, and exempts to dry, exempt to forge Burning, the most modified utilization, in acidity, pH value is 3-4.
Preferably, Gypsum Fibrosum is half water ardealite and half water desulfurated plaster, and performance is: the presetting period is 3-5min, water consumption ≤ 65%, 2h rupture strength >=3MPa, 2h comprcssive strength >=5.5MPa.
Preferably, breeze is S95 powder.
Preferably, cement is 42.5 Portland cements.
Preferably, sulphate aluminium cement is double-quick cement.
Preferably, water reducer is polycarboxylate water-reducer, water-reducing rate >=22%.
Preferably, exciting agent is one or more of calcium chloride and potassium sulfate.
Preferably, glass fibre length 3-4cm.
Preferably, basic matterial is quick lime, content >=70% of CaO.
The preparation method that a kind of water-fast fluorgypsum mould closes, comprises the following steps:
A, by component according to weight ratio pour into stirring container mix and blend 3-5min, be ready for suitable quantity of water, by mixing Component is poured into water stirring 30s；
B, mixture step a obtained pour die for molding into, quiet stop the demoulding after 10min；
C, the mould that covered rearing with plastic film step b is obtained close 3 days wet support.
The invention has the beneficial effects as follows:
1, the present invention use Binder Materials be fluorgypsum, implement again exempt from dry, exempt from calcine technology, save equipment and A large amount of inputs of Factory Building, decrease the discharge of carbon dioxide, decrease energy resource consumption, beneficially the protection of environment.
2, another reason that the present invention uses fluorgypsum to be Binder Materials, is that its sulfate dihydrate calcium content is all natural Or the highest in industry by-product gypsum, so intensity is also that other Gypsum Fibrosum are incomparable.
3, this invention takes the fluorgypsum water-fast modification technology of enforcement, ensureing that prior art initial set is fast, the demoulding is fast On the basis of, add resistance to water function, solve intensity low simultaneously, the deficiency of high, the long green hair of water absorption rate, widen range of application, Improve product grade, meet the demand in market.
