Abstract
The invention discloses caulking desulfurization gypsum. The caulking desulfurization gypsum comprises the following components in percentage by weight: 0.1-8% of conditioning agent, 1-25% of pulverized fuel ash, 0.3-1% of water-retaining agent, 0.01-0.2% of adhesive agent, 0.01-0.5% of retarder and balance of construction desulfurization gypsum. In the invention, the caulking desulfurization gypsum is produced by making full use of two industrial solid wastes the desulfurization gypsum and the pulverized fuel ash of a fuel electric plant. Besides, the caulking desulfurization gypsum has higher intensity, and the maximum folding strength can reach 4.0 MPa, while the folding strength of the caulked joint of natural gypsum is generally in the range of 3.0-3.4 MPa. In addition, the caulking desulfurization gypsum has good cracking resistance and is detected according to the experimental requirements of ASTM C475/C475M-02. The caulking desulfurization gypsum has no cracks in any form, while the caulked joint of the natural gypsum can generate some fine cracks within the index range generally.
Description
Technical field
The present invention relates to a kind of filleting gypsum.
Background technology
In recent years, Chinese society Economic development face, topsoil also is on the rise, and wherein the discharging of sulfurous gas is one of important factor that causes topsoil.Relevant data shows, the total emission volumn of China's sulfurous gas in 2006 is 4,500 ten thousand tons, and wherein the sulfur dioxide emissions total amount of thermoelectric industry surpasses 50% of total release, expects the year two thousand twenty, and the quantity discharged of sulfurous gas will reach 9000 tons.The lime-gypsum method desulfurization has solved the pollution problem of Sulfur Dioxide In The Atmosphere, has also produced a large amount of using industrial solid waste-desulfurated plasters simultaneously.
The filleting gypsum is normally made by natural plaster of Paris, does not also adopt desulfurated plaster to prepare the report of filleting gypsum at present.Mainly be to adopt desulfurated plaster to prepare the filleting gypsum to exist intensity lower, and easy problems of crack.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of desulfurized gypsum to substitute natural gypsum that can utilize and prepares the filleting gypsum, can reduce the cost of filleting putty, and fully utilize the desulfurated plaster resource.
In order to address the above problem, the invention provides a kind of caulking desulphurization gypsum and comprise following component: adjusting agent 0.1～8%, flyash 1～25%, water-holding agent 0.3～1%, caking agent 0.01～0.2%, retardant 0.01～0.5%, surplus is the building desulfurated plaster; Wherein, described per-cent is weight percentage.
Preferably, described adjusting agent is sulfonate.
Preferably, described water-retaining admixture is methylcellulose gum, Xylo-Mucine or ether of cellulose.
Preferably, described caking agent is rubber powder.
Preferably, described retardant is citric acid.
Preferably, the granularity of described flyash is greater than 80 orders.
The present invention takes full advantage of two kinds of using industrial solid waste-desulfurated plasters and the flyash in fuel-burning power plant, produces a kind of caulking desulphurization gypsum.In addition, caulking desulphurization gypsum of the present invention has higher intensity, and its folding strength is the highest can to reach 4.0Mpa, and the folding strength of plaster of paris filleting is generally at 3.0～3.4Mpa.Caulking desulphurization gypsum of the present invention has well anti-cracking performance in addition, detect according to ASTM C475/C 475M-02 requirement of experiment, caulking desulphurization gypsum of the present invention is without what crackle of appointing form, and plaster of paris filleting generally can produce the minute crack in some indication ranges.
