Embodiment 1
[0050](1) Hydrophobic treatment: Add methyl hydrogen-containing silicone oil accounting for 3% of the pretreated aluminum ash to the pretreated aluminum ash, stir evenly at a high speed, stir and heat up to 150°C for 1 hour to cross-link and solidify to form a complete hydrophobic surface;
[0051] (2) Hydrophilic treatment: add a sodium dodecylbenzenesulfonate solution with a mass fraction of 10% according to the dosage ratio of 1g:0.1ml to the aluminum ash after the hydrophobic treatment, and stir evenly to form a hydrophilic surface;
[0052] (3) Brick making: Mix 55 parts of aluminum ash after hydrophilic treatment, 40 parts of phosphogypsum, 8 parts of cement, 3 parts of aluminum dihydrogen phosphate, and 18 parts of water, and then use a brick making machine to press and shape it, and maintain it for seven days. Get the product.
Embodiment 2
[0054] (1) Hydrophobic treatment: add methyl ethoxy silicone oil accounting for 0.5% of the mass of the pretreated aluminum ash to the pretreated aluminum ash, stir evenly at a high speed, stir and raise the temperature to 250°C for 1.2 hours to cross-link and solidify to form complete hydrophobic surface;
[0055] (2) Hydrophilic treatment: add a sodium dodecylbenzenesulfonate solution with a mass fraction of 20% according to the dosage ratio of 1g:0.05ml to the aluminum ash after the hydrophobic treatment, and stir evenly to form a hydrophilic surface;
[0056] (3) Brick making: Mix 60 parts of aluminum ash after hydrophilic treatment, 50 parts of phosphogypsum, 3 parts of cement, 6 parts of water-based polyurethane, and 25 parts of water, and then use a brick making machine to press and shape it, and maintain it for seven days to obtain the finished product .
Embodiment 3
[0058] (1) Hydrophobic treatment: add MHX-1107 hydrogen-containing silicone oil accounting for 2% of the pretreated aluminum ash to the pretreated aluminum ash, stir at a high speed evenly, stir and raise the temperature to 150°C for 0.3 hours to cross-link and solidify to form complete hydrophobic surface;
[0059] (2) Hydrophilic treatment: add fatty alcohol ether sulfate solution with a mass fraction of 5% to the aluminum ash after hydrophobic treatment according to the dosage ratio of 1g:0.2ml, and stir evenly to form a hydrophilic surface;
[0060] (3) Brick making: Mix 50 parts of aluminum ash after hydrophilic treatment, 30 parts of phosphogypsum, 10 parts of cement, 6 parts of acrylic acid emulsion, and 10 parts of water, and then use a brick making machine to press and shape it, and maintain it for seven days to obtain the finished product .
