[0018] Example 1:
[0019] In the examples of this application, a semi-dry desulfurization ash interior wall putty is described.
[0020] The composition of the interior wall putty is (in mass percentage): semi-dry desulfurization ash 25% to 35%, steel slag 10% to 20%, slag powder 30% to 45%, double fly powder 10% to 25%, water retention agent 0 %~5%, latex powder 0%~5%.
[0021] Among them, the semi-dry desulfurization ash is specifically the desulfurization ash produced by the semi-dry flue gas desulfurization system of a steel plant.
[0022] Further, please refer to the preparation method of the interior wall putty of the present invention figure 1 ,include:
[0023] S1, drying the semi-dry desulfurization ash so that the water content of the semi-dry desulfurization ash is less than 1% of its own mass.
[0024] S2: Dry the steel slag and grind it into powder using a ball mill.
[0025] In a specific implementation process, after drying the semi-dry desulfurization ash, the water co...
Example Embodiment
[0029] Example 2:
[0030] Take the sintering semi-dry desulfurization ash, iron separation steel slag, and slag from the iron and steel plant and put them into a 100 ℃ oven for drying. After drying, the moisture content of the semi-dry desulfurization ash, iron separation steel slag, and slag is less than 1% of their own mass. %. After drying, the steel slag and slag are ground. After grinding, the fineness of the steel slag is above 350 mesh, and the specific surface area of the slag powder is not less than 450m. 2 / kg spare.
[0031] Weigh 25% desulfurization ash, 15% powdered steel slag, 40% slag powder, 15% double fly powder, 2% water retention agent, 3% latex powder, and put the above raw materials into the mixer at the same time. , Use a centrifugal three-shaft mixer to mix for 15 minutes, stir evenly, and then send it to a vacuum tank for storage through a packer or air pressure pump.
