Preparation method of corundum mullite light brick
The invention relates to the technical field of building production, and discloses a preparation method of a corundum mullite light brick. The preparation method comprises the following seven steps of: performing screening and grinding; performing uniform stirring; adding a dispersant and a binder; adjusting the pH value; preparing a suspension; carrying out injection molding and demolding; and carrying out high temperature sintering. When the pH value is adjusted, the temperature of slurry is 40-60 DEG C, and the pH value of the slurry is 8-10, the demolding and drying temperature is set to be 80 DEG C, and the vibration frequency of a vibrator is set to be 2000 times per minute; and during sintering, the heat preservation temperature is set to be 1500 DEG C, the heat preservation and sintering time is 5 hours, the grinding time of a ball mill is 10 minutes, and the diameter of fine particles obtained after grinding is smaller than 1 mm. According to the preparation method of the corundum mullite light brick, the quality of the corundum mullite light brick can be improved; thevibrator is adopted, so that the situation that the rejection rate is increased due to the influence of bubbles in the corundum mullite light brick during injection molding on the sintering quality of subsequent sintering is avoided, and production efficiency and production quality are improved.
本发明涉及建筑生产技术领域，公开了一种刚玉莫来石轻质砖的制备方法，包括以下七个步骤：筛分研磨、搅拌均匀、加入分散剂和结合剂、调节酸碱度、制成悬浮体、注模与脱模、高温烧结，调节酸碱度时，浆料温度为40‑60℃，浆料的酸碱度为8‑10，脱模干燥温度设置在80℃，震动器的震动频率设置在2000次每分钟，烧结时保温温度设置为1500℃，保温烧结时间为5小时，球磨机的研磨时间10分钟，研磨后的细颗粒直径小于1mm，该刚玉莫来石轻质砖的制备方法，通过筛分研磨的设置，达到了提高刚玉莫来石轻质砖品质的目的，通过震动器的设置，达到了防止注模时内部存在气泡，影响后续烧结的烧结质量，导致废品率增高，提高了生产效率和生产质量。
