Method for preparing gel material from coal gangue, gel material and application
The invention discloses a method for preparing a gel material from coal gangue and a composite material, and the method comprises the following steps: crushing coal gangue, gypsum solid waste and limestone, and uniformly mixing to form a first mixture; the first mixture is fired within a first temperature range, and clinker is obtained after firing is completed; crushing and uniformly mixing the coal gangue, the red mud and the gypsum to form a second mixture; the second mixture is fired in a second temperature range, a mixed material is obtained after firing is completed, and the second temperature range is lower than the first temperature range; and proportioning the clinker and the mixture according to a preset proportion to obtain the required gel material. According to the method, an external heat source does not need to be added, and the heat value in the coal gangue is effectively utilized, so that efficient consumption of the coal gangue is realized, high-added-value products are prepared, and the selling radius of the coal gangue is effectively widened.
本申请公开了一种煤矸石制备凝胶材料的方法及复合材料，包括：将煤矸石、石膏固废和石灰石破碎后混匀，形成第一混合料；在第一温度范围内烧制所述第一混合料，烧制完成后获得熟料；将煤矸石、赤泥和石膏破碎混匀，形成第二混合料；在第二温度范围内烧制所述第二混合料，烧制完成后获得混和料，其中所述第二温度范围低于所述第一温度范围；按照预设比例，配比所述熟料和所述混合料，以获得所需的凝胶材料。本申请的方法无需添加外加热源，有效利用煤矸石中热值，从而实现高效消纳煤矸石并制备高附加值产品，有效拓宽了煤矸石销售半径。
