Embodiment 1

[0032] Mix 24% sugar (sucrose), 15% starch, 0.1% sodium phosphate, 0.03% fatty acid salt / surfactant (soap) and 61% water, the main active ingredient in the sugar and water solution. Of course, the concentration of this mixture may vary, but it is still possible to maintain the effectiveness of this formula. In this example, the effective temperature range of the formulation is from 0 to 150 degrees Celsius.

Embodiment 2

[0034] The reactant is 30% sucrose, 19% starch, 0.1% sodium phosphate, 0.03% fatty acid salt / surfactant (soap), and the vinyl copolymer is generated after the reaction. Among them, water is the solvent, and all the reactions take place in the solution, and the ratio of water also determines the concentration of the final emulsion. The specific reaction method is as follows: firstly, 30% sucrose is dissolved in 50% quality water, then 19% quality starch is added to make it completely evenly mixed, then 0.1% sodium phosphate and 0.03% fatty acid salt / surfactant are added agent (soap), wait for the temperature to drop to room temperature before filling into cans.

Embodiment 3

[0036] 17% of sucrose, 34% of starch, 0.08% of sodium phosphate, 0.04% of fatty acid salt / surfactant and 48% of water, the allowable error of each component is ± 5%, mixed according to the mode of the foregoing examples, to obtain the compound required Vinyl copolymer emulsion.

[0037] In the above embodiments, less than 1% of insecticides, fungicides or their combination can be added to the vinyl copolymer emulsion, which can improve the storage stability of the vinyl copolymer emulsion.

[0038] The vinyl copolymer emulsion of the present invention has been described in detail above. On this basis, the present invention can prepare novel sulfuric acid-resistant and anti-corrosion materials from the above-mentioned vinyl copolymer emulsion and vermiculite. The specific process is to uniformly mix vinyl copolymer emulsion and vermiculite particles, and statically press molding in a molding die, and then obtain a sulfuric acid-resistant and anti-corrosion material with vermic...

Abstract

The invention discloses a vinyl copolymer emulsion which is obtained by mixing 25-35% of saccharose, 10-20% of starch, 0.05-0.15% of sodium phosphate, 0.01-0.05% of fatty acid salt / surface active agent and 45-65% of water. The invention further discloses a sulfuric acid resistant and corrosion resistant material. The vinyl copolymer emulsion and vermiculite granules are blended uniformly, static pressure molding is performed in a molding mold, and demolding and drying are performed to obtain the sulfuric acid resistant and corrosion resistant material for a power plant chimney internal steel barrel liner. The vinyl copolymer emulsion is stuck to vermiculite so as to obtain the sulfuric acid resistant and corrosion resistant material, and the power plant chimney internal steel barrel liner can be manufactured economically and efficiently.

Description

technical field [0001] The invention relates to the flue gas desulfurization technology of a power plant, in particular to the material for the inner lining of the chimney steel cylinder of the power plant, in particular to the vinyl copolymer emulsion and the sulfuric acid-resistant and corrosion-resistant material for the inner lining of the steel inner cylinder of the chimney of the power plant. Background technique [0002] As the problem of air pollution becomes more and more serious, the flue gas desulfurization of power plants has attracted great attention. Relatively speaking, the flue gas desulfurization of power plants in developed countries such as Europe and the United States is relatively early and has accumulated some valuable experience; while the flue gas desulfurization of domestic power plants is a matter of recent years. The technological blockade of developed countries in Europe and the United States, so it is necessary to fully study this technology. ...
