Abstract
The invention discloses a novel calcination-free desulfurized gypsum brick, belonging to the production field of building bricks. The calcination-free desulfurized gypsum brick comprises the following components in parts by weight: 45-55 parts of desulfurized gypsum, 25-35 parts of coal ash, 5-10 parts of No. 32.5 cement, 4-10 parts of triethanolamine, 3-5 parts of sodium hydroxide, 3-5 parts of sodium silicate, 3-5 parts of sulfate, 1-2 parts of calcium oxide and 0.05-0.1 part of reinforced fiber. The calcination-free desulfurized gypsum brick has the advantages of energy conservation and, good product quality, low price and the like, is environment-friendly, and treats wastes with wastes.
Description
Technical field
Patent of the present invention designs a kind of building brick, and specifically a kind of novel calcination-free desulfurized gypsum brick is suitable for house owed by a citizen, ordinarily resident building, internal partition wall.
Background technology
Means of flue gas desulfurization of power plant gypsum and flyash are two big solid waste of coal-burning power plant.The present invention can be good at utilizing this two big industrial residue, not only can produce huge economic benefit and also can produce the environmental benefit that to estimate simultaneously, the raw material of novel calcination-free desulfurized gypsum brick is easy to get and is industrial residue, the treatment of wastes with processes of wastes against one another, energy-conserving and environment-protective, this gypsum brick need not to calcine and has not only solved a large amount of non-renewable land resourcess of common brick consumption and also solved the big shortcoming of calcining power consumption, and market outlook are huge.
Summary of the invention
The objective of the invention is to research and develop that a kind of low power consuming, low cost, production technique are simple, good product quality, environmentally friendly calcination-free desulfurized gypsum brick.Solving means of flue gas desulfurization of power plant gypsum and flyash is problems such as coal-burning power plant's land occupation, contaminate environment.
The technology of the present invention task realizes in such a way: novel calcination-free desulfurized gypsum brick is made by the batching of following weight proportion:
Concrete steps are: press said ratio with desulfurated plaster, flyash, cement, sodium hydroxide, water glass, vitriol, calcium oxide, mixing and stirring is even by proportioning adding trolamine and fortifying fibre aqueous solution again.Ratio of water to material is 0.25～0.5.
As for mould internal vibration compression moulding, when compression moulding, pressure is 100-300 newton's power with compound.At room temperature leave standstill the demoulding after 24 hours behind the specimen molding, promptly obtained the desulfurized gypsum brick finished product in natural curing 20-30 days.
The fineness of described desulfurated plaster, flyash and cement is less than 200 orders.
Described fortifying fibre comprises: the glass fibre after polypropylene fibre, the process heat after the acid etching, vegetable fibre etc.
Described vitriol comprises: sodium sulfate, vitriolate of tartar, Tai-Ace S 150, potassium aluminium sulfate etc.
The present invention improves the bulk strength of desulfurized gypsum brick by hardening accelerator and organic solidifying agent, again by alkali-activator, sulphate activation agent and cement excitation flyash activity, add fortifying fibre at last anti-folding, the ultimate compression strength of desulfurated plaster and flyash system are improved, produce novel calcination-free desulfurized gypsum brick.
Calcination-free desulfurized gypsum brick of the present invention compared with prior art has following outstanding feature:
1), raw material is easy to get, main raw material is means of flue gas desulfurization of power plant gypsum and flyash, these two kinds of raw materials are two big solid waste of coal-burning power plant, and the requirement of using industrial residue making calcination-free desulfurized gypsum brick not only to meet national energy-saving and emission-reduction can also obtain exempting the support on policy of tax revenue.
2), product need not the main component terra alba of desulfurated plaster is sintered into calcium sulphate hemihydrate or anhydrous calciumsulphate, and curing condition is simple, need not other calciners and becomes to produce more energy-conserving and environment-protective with technology.
3), the quality product height, cost is low, the life-span is long, all meets industry standard in anti-water, anti-folding, resistance to compression, can substitute fully and glue brick.And have insulation, fire prevention, light weight, characteristics such as firm, attractive in appearance.
Embodiment
Produce novel calcination-free desulfurized gypsum brick according to following quality:
Prescription
Press said ratio with desulfurated plaster, flyash, cement, sodium hydroxide, water glass, vitriol, calcium oxide, mixing and stirring is even by proportioning adding trolamine and fortifying fibre aqueous solution again.Ratio of water to material is 0.48;
As for mould internal vibration compression moulding, when compression moulding, pressure is 100-300 newton's power with compound.At room temperature leave standstill the demoulding after 3 days behind the specimen molding, natural curing promptly obtained the desulfurized gypsum brick finished product in 25 days after the demoulding.
The every technical indicator of novel calcination-free desulfurized gypsum brick of gained is as shown in Table 1:
Table one:
Claims (5)
