Double-sided matte glaze applying grey tile reduction firing process
The invention discloses a double-sided matte glaze applying grey tile reduction firing process, and belongs to the technical field of building materials. Weathered red shale is used as a green body raw material; matte glaze is obtained by firing a glaze material; the process comprises the following seven specific process steps: dry-method powder preparation, wet-method powder preparation, green body compact molding, drying, mixing, glaze throwing and firing. The process adopts a roller kiln to sinter in a high-temperature reducing atmosphere; detection data of flexural strength, frost resistance, rapid cooling and rapid heating and acid and alkali resistance of the prepared product all meet technical requirements of GB/T21149-2019. And the green body and the glaze are close in color, are cyan black, are beautiful and elegant, are fine and smooth in texture, are stronger in overall anti-pollution capability, are low in water absorption rate, and do not generate expansion and cracking phenomena due to moisture absorption in the later period.
本发明公开了一种双面施哑光釉青瓦还原烧成工艺，属于建筑材料技术领域，其以风化质红页岩为坯体原料，哑光釉为釉料烧成得到，具体工艺步骤包括干法制粉、湿法制粉、压坯成型、干燥、混合、甩釉、烧成七个步骤，该工艺采用辊道窑高温还原气氛烧成，制得产品的抗折强度、抗冻性能、急冷急热、耐酸碱的检测数据均达到了GB/T21149‑2019的技术要求，且坯体与釉料颜色相近，都呈青黑色，美观素雅，质感细腻，整体抗污能力更强，吸水率低，后期坯体因吸湿不会产生膨胀和龟裂现象。
