Plate-shaped corundum ball for high-purity bulk density petrochemical filler
The invention discloses a tabular corundum ball for a high-purity bulk density petrochemical filler, and belongs to the technical field of fire resistance. Comprising the following raw materials: 80%-85% of a tabular corundum ball basic mixture, 6%-12% of lignocellulose, 5%-15% of aluminate cement, 3%-8% of diatomite, 1%-2% of aluminum oxide, 1%-5% of calcium carbonate and 10%-15% of kaolin. According to the tabular corundum ball for the high-purity bulk density petrochemical filler, firstly, magnesium spinel and kaolin are combined, the purity and bulk density of a finished product are improved, diatomite and lignocellulose are utilized, the structural strength of the outer wall of the finished product can be guaranteed, the cracking phenomenon caused by the high sintering temperature is avoided, and the defective rate of production is reduced; and secondly, by utilizing the outer wall of the product, the thermal expansion resistance of the product can be ensured, and the application range is widened.
本发明公开了高纯度堆积密度石化填料用板状刚玉球，属于耐火技术领域，该高纯度堆积密度石化填料用板状刚玉球，包括如下原料：板状刚玉球基础混合料80％‑85％、木质纤维素6％‑12％、铝酸盐水泥5％‑15％、硅藻土3％‑8％、氧化铝1％‑2％、碳酸钙1％‑5％与高岭土10％‑15％。该高纯度堆积密度石化填料用板状刚玉球，首先结合镁尖晶石和高岭土，提高成品的纯度和堆积密度，且利用硅藻土和木质纤维素，可以保证成品外壁的结构强度，避免因为烧结的温度较高导致的龟裂现象，降低生产的次品率，其次利用产品的外壁，可以保证产品的抗热膨胀性能，提高适用的范围。
