Environment-friendly high-whiteness domestic ceramic product and preparation process thereof
The invention relates to the technical field of ceramics, and particularly discloses an environment-friendly high-whiteness domestic ceramic product which comprises Dehua kaolin, albite, quartz, zirconium silicate and composite granules. The composite granules are prepared by coating fluorite tailing powder and calcined smithsonite powder with Dehua Longque red soil dispersed slurry, granulating and drying. The fluorite tailings sintered ceramic is high in whiteness, high in strength, good in thermal shock resistance, suitable for domestic ceramics, energy-saving, environment-friendly, large in sintering range and high in yield due to the fact that the fluorite tailings are recycled. Particularly, in the staged heating, oxidizing and firing process, silicon and aluminum in the Dehua longque red soil dispersed slurry react to serve as mullite crystals, the fluorite tailing powder and the calcined smithsonite powder act synergistically to reduce the melting temperature of the red soil silicon and aluminum, continuous curing of the mullite crystals is accelerated, and a compact framework is formed; the breaking strength and the thermal shock resistance of the green body are favorably enhanced.
本发明涉及陶瓷技术领域，具体公开一种环保高白度日用陶瓷制品，包括德化高岭土、钠长石、石英、硅酸锆、复合颗粒料。复合颗粒料由德化龙阙红土分散浆料包覆萤石尾矿粉末和煅烧菱锌矿粉末后造粒烘干而得。本发明白度高、强度高且抗热震性佳，适用于日用陶瓷，且由于回收利用了萤石尾矿，节能环保，烧成范围大，成品率高。尤其是在分阶段升温氧化烧制过程中，德化龙阙红土分散浆料中的硅铝反应作为莫来石晶体，萤石尾矿粉末和煅烧菱锌矿粉末协同作用降低红土硅铝熔融温度，加速莫来石结晶连续熟化形成致密骨架，利于增强坯体的抗折强度和抗热震性能。
