Anti-seepage high-strength forsterite light heat-insulating brick and preparation method thereof
The invention discloses an anti-seepage high-strength forsterite light heat-insulating brick, which comprises the raw materials of forsterite powder, magnesia powder, fused magnesia-alumina spinel powder and a pore-forming material, wherein the particle size d of the magnesia powder and the forsterite powder is less than or equal to 0.044 mm, the particle size d of the fused magnesia-alumina spinel powder is less than or equal to 0.088 mm, the particle size d of the pore-forming material is less than or equal to 0.3 mm, and the mass ratio of the forsterite powder to the magnesia powder to thefused magnesia-alumina spinel powder to the pore-forming material is (30-42): (8-15): (5-10): (40-60). The preparation method comprises the steps of S1, purchasing raw materials and processing the rawmaterials to required granularity, and adding a pore-forming material and a binding agent into a granulator for granulation; S4, selecting magnesia powder, forsterite powder, fused magnesia-alumina spinel powder and the granular pore-forming material, and putting the materials into a mixing machine for full mixing; S5, ageing the materials, and then putting the aged materials into the mixing machine for secondary mixing; and S6, conducting mechanical pressing forming, and then conducting kiln loading and firing.
本发明公开了一种防渗高强镁橄榄石轻质隔热砖，其原料包括镁橄榄石粉、镁砂粉、电熔镁铝尖晶石粉和造孔材料，所述镁砂粉、镁橄榄石粉的粒径d≤0.044mm，电熔镁铝尖晶石粉的粒径d≤0.088mm，造孔材料的粒径d≤0.3mm，所述镁橄榄石粉、镁砂粉、电熔镁铝尖晶石粉和造孔材料的质量比为：30~42：8~15：5~10：40~60。该制备方法的步骤是：S1、购入原料并将原料加工到所需的粒度；将造孔材料、结合剂加入到造粒机中进行造粒；S4、选取镁砂粉、镁橄榄石粉、电熔镁铝尖晶石粉和粒状的造孔材料一起投入到混合机中进行充分混合；S5、困料，然后放入混合机中进行二次混合；S6、机压成型然后装窑烧成。
