Embodiment 1
[0018] An far-infrared radiation function powder prepared using microwave heating using industrial waste, the weight percentage group of the powder raw material is: molten stone 65 wt%, long quartz sand 20%, coal gangue 7 wt%, magnesium clay 8 wt%.
[0019] The far-infrared emissivity of the powder at room temperature 8 to 14 μm is 0.93 / %.
[0020] The molten stone is a photovoltaic industry waste, and the long stone tail sand is a selection of waste materials in the long stone mine, and the coal gangue is solid waste in coal.
[0021] The preparation method of the above powder includes the following steps:
[0022] Step 1: First crush the molten stone with a jaw crusher to a powder having a particle size of less than 3 mm, and then constitute a ingredient according to the above formulation, with a rapid frozen mill mill, using a zirconia ball grinding tank and zirconium oxide ball mill, tripopolyphosphate Sodium as a dispersant, material, ball, and water ratio of 1: 5: 0.5;
