Low-heat-conductivity multi-layer composite magnesium-hercynite brick and preparation process thereof
The invention relates to a low-heat-conductivity multi-layer composite magnesium-hercynite brick and a preparation process thereof. The low-heat-conductivity multi-layer composite magnesium-hercynite brick is prepared from the following raw materials in percentage by weight: 70-95% of microporous high-purity magnesia, 4-15% of hercynite, 2-10% of light forsterite, and 1-5% of a binding agent in a working layer, and 10-50% of microporous high-purity magnesia, 50-80%of light forsterite and 1-10% of nano aluminum oxide micro powder in a heat insulation layer. The heat insulation layer is a nano aerogel plate. According to the low-heat-conductivity multi-layer composite magnesium-hercynite brick and the preparation process thereof, the overall volume density is small, the heat conductivity coefficient is far lower than that of an existing product, the energy consumption of a thermotechnical kiln can be remarkably reduced, the purposes of saving energy and reducing consumption are achieved, and in the actual production process, production and preparation are convenient and efficient, so that actual application and popularization are facilitated, and therefore, the problems of high energy consumption and short service life of the existing cement kiln adopting pleonaste bricks are effectively solved.
本发明涉及一种低导热多层复合镁铁铝尖晶石砖及其制备工艺，由下述重量百分比的原料制成：工作层微孔高纯镁砂70～95％、铁铝尖晶石4～15％、1～8％、轻质镁橄榄石2～10％、结合剂1～5％；保温层微孔高纯镁砂10～50％、轻质镁橄榄石50～80％、纳米氧化铝微粉1～10％；隔热层为纳米气凝胶板。该低导热多层复合镁铁铝尖晶石砖及其制备工艺，其整体的体积密度小，导热系数远低于现有产品，能显著降低热工窑炉的能耗，实现节能降耗的目的，并且在实际生产的过程中，生产制备方便且高效，因此方便了进行实际推广和应用，从而有效的解决了现有水泥窑采用镁铁尖晶石砖会出现能耗高以及使用寿命短的问题。
