Novel self-releasing glaze fire-resistant alkali-resistant brick
The invention discloses a novel self-releasing glaze fire-resistant and alkali-resistant brick, which belongs to the technical field of self-releasing glaze of heavy fire-resistant and alkali-resistant bricks, the novel self-releasing glaze fire-resistant and alkali-resistant brick mainly comprises an Al2O3 + SiO2 system, the sum of Al2O3 and SiO2 is 94%, the refractoriness is 1800 DEG C, the volume density is 2.2 g/cm < 3 >, the apparent porosity is 15%, and the compressive strength is 40 Mpa. The preparation process specifically comprises the following steps: 1, preparing; raw material screening: raw materials are screened, and main components comprise kaolin, mullite and aluminum oxide; crushing and grinding kaolin, mullite and aluminum oxide, and mixing the additional materials again according to the mixing ratio; brick blanks are pressed; performing high-temperature calcination synthesis; crushing particles; mixing according to grain composition and a binding agent; brick pressing; and the novel self-releasing glaze fire-resistant alkali-resistant brick is fired according to drawing brick type requirements. In the refractory alkali-resistant brick prepared by the invention, stable formation of a mullite crystal phase is successfully realized by accurately controlling the raw material ratio and a special preparation process, and the conventional reversibility of the mullite crystal phase is broken, so that the alkali erosion resistance of the brick body is remarkably improved.
本发明公开了一种新型自释釉的耐火耐碱砖，属于重质耐火耐碱砖的自释釉技术领域，主要成分Al2O3+SiO2体系，Al2O3+SiO2总计94％，耐火度1800℃，体积密度2.2g/cm3，显气孔率15％，耐压强度40Mpa。制备工艺，具体包含如下步骤；原料筛选：对于原料进行筛选，主要成分包括高岭土、莫来石、氧化铝；将高岭土、莫来石、氧化铝、粉碎磨细、外加材料按配合比再次混合；压制砖胚；高温煅烧合成；破碎颗粒；按颗粒级配+结合剂混合；压砖；按照图纸砖型要求烧成新型自释釉耐火耐碱砖。在本发明所制备的耐火耐碱砖中，通过精确控制原料配比和特殊的制备工艺，成功实现了莫来石晶相的稳定形成，打破了其常规的可逆性，从而显著提高了砖体的抗碱侵蚀能力。
