Formula and preparation method of lithium glass fused quartz high-heat-resistance cooker porcelain body
The invention discloses a formula and a preparation method of a high-heat-resistance glass lithium fused quartz cooker porcelain body. The high-heat-resistance glass lithium fused quartz cooker porcelain body comprises a glass lithium material, fused quartz, clay, kaolin and a calcium raw material. The blank material comprises the following chemical components: 260-65% of Si < 2 >, 22-24% of Al < 2 > O < 2 >, 1.5-2% of Fe < 20 >, 1-1.2% of Ca < 1 >, 0.45-0.55% of Mg < 2 >, 0.3-0.4% of K < 20 >, 0.25-0.3% of Na < 20 >, 0.45-0.5% of Li < 20 >, 0.6-0.65% of B < 20 >, 8-8.5% of ignition loss and 8-8.5% of ignition loss, the blank material is mixed and stirred by a wet method to form slurry, water and an additional dispergator are added, the mixture is stirred for 2-2.5 hours, and the slurry is discharged and sieved by a 50-mesh sieve. The use amount of a glass lithium material in a blank material formula is controlled to be within 10%, the use amount of fused quartz is controlled to be within 30-34%, and the grain composition is controlled to be a mixture of 70-150 meshes, so that the heat resistance of a product is enhanced, meanwhile, a pair of stirring columns are driven by a bearing rotating plate, and the blank material is fully stirred along with spraying of water, so that the heat resistance of the product is improved. And iron contained in the blank is removed through the stirring column, so that the purity of the formula is higher.
本发明公开了玻璃锂熔融石英高耐热炊具瓷坯配方及制备方法，包括玻璃锂料，熔融石英，粘土，高岭土，钙质原料；坯料的化学成分组成如下：Si0260‑65％，A120322‑24％，Fe2031.5‑2％，Ca01‑1.2％，Mg00.45‑0.55％，K200.3‑0.4％，Na200.25‑0.3％，Li200.45‑0.5％，B2030.6‑0.65％，烧失量8‑8.5％，灼失量8‑8.5％，将坯料采用湿法混合搅拌化浆料，加入水和外加解胶剂，搅拌2‑2.5小时后，放浆过50目筛，本发明通过玻璃锂与熔融石英结合组成的坯料，将坯料配方中玻璃锂料用量控制在10％以内，将熔融石英用量控制在30‑34％内，将颗粒级配控制在70‑150目的混合料，从而增强产品耐热性能，同时利用承重转板带动一对搅拌柱，并伴随水的喷洒对坯料进行充分搅拌，在通过搅拌柱除去坯料内含有的铁质，从而使配方纯度更高。
