[0026] The invention also discloses a method for preparing glassy magnesium slabs by using mineral wool waste slag, which includes: grinding the mineral wool cutting waste slag, soaking the mineral wool furnace bottom waste slag in magnesium chloride solution or magnesium sulfate solution, and using the propulsive force of the liquid to make the furnace bottom waste slag Uniformly disperse to form a premix; mix the ground mineral wool cutting waste, premix, magnesium oxide, light aggregate and admixture, and dry; then dehydrate and maintain until the moisture content is less than 8%, and obtain mineral wool waste slag modified Sexual glass magnesium plate.
[0027] Wherein, magnesium chloride solution or magnesium sulfate solution and magnesium oxide form a gelling material, and the molar ratio of magnesium oxide: magnesium chloride or magnesium sulfate is 7-13:1. Specifically, the quality of mineral wool cutting waste slag accounts for 10% to 20% of the mass of the cementitio...
Embodiment 1
[0033] Use a ball mill to grind mineral wool cutting waste to 0.075-0.120mm for later use; put 6.8kg of mineral wool bottom waste slag into 58.5kg of magnesium sulfate solution for soaking, use the propulsive force of the liquid to evenly disperse the bottom waste slag to form a premixed solution. Mix 13.6kg of mineral wool cutting waste, premix, 68kg of magnesia, and 2.0kg of admixture and pour it into the mold, then send it to a tunnel dryer at 180°C for 15 minutes, and then dry the dried glass magnesium After demoulding, the slab is transferred to the warehouse for natural maintenance until the moisture content is less than 8%, and then a glass magnesium slab of 2440mm×1220mm×5mm is made, the total mass of the slab is 148.9kg, and the density of the slab is 1000kg / m 3 . The performance test was done on the 21st day, see Table 1 for details.
Embodiment 2
[0035] Use a ball mill to grind mineral wool cutting waste to 0.075-0.120 mm for later use; put 12 kg of mineral wool bottom waste slag into 105 kg of magnesium sulfate solution for soaking, use the propulsive force of the liquid to evenly disperse the bottom waste slag to form a premixed solution. Mix and stir 24kg of mineral wool cutting waste, premix, 122kg of magnesium oxide, 1.3kg of polyphenylene particles, and 2.0kg of admixture, pour it into a mold, and then put it into a tunnel dryer at 80°C for 20 minutes. The dried glass magnesium slab is removed from the mold and transferred to the warehouse for natural maintenance until the moisture content is less than 8%, and then a 2440mm×1220mm×15mm glass magnesium slab is made, with a total mass of 267.9kg and a density of 600kg / m 3 . The performance test was done on the 21st day, see Table 1 for details.
