Multi-layer composite thick glaze white porcelain and manufacturing process thereof
The invention discloses a multi-layer composite thick glaze white porcelain and a manufacturing process thereof, and belongs to the technical field of white porcelain. The multi-layer composite thick glaze comprises a bottom layer, a transition layer and a surface layer; the glaze of the bottom layer comprises potassium feldspar, calcite, kaolin, calcined kaolin, calcined talc, ZnO, SiO2 and B2O3; the glaze of the transition layer comprises potassium feldspar, calcite, kaolin, MgO, Al2O3 and the like; and the glaze of the surface layer comprises potassium feldspar, calcite, kaolin, TiO2, NaO, CaO, Fe2O3, MgO, Al2O3 and the like. According to the invention, a multi-layer glazing method is adopted for preparation; the purity of the glaze is gradually improved from the bottom layer to the surface layer, and the forming quality of the glaze surface is improved; and by controlling the thickness between every two layers and the feeding mode of glaze water and glaze on each layer, the connection strength between the glaze surfaces is improved, the three layers of glaze surfaces are prepared by adopting a ZnO-MgO-B203-Al2O3-SiO2 system, and B2O3 is added in the system, so that the wear resistance and hardness of the glaze surfaces are improved, the porosity of the glaze surfaces is reduced, and the corrosion resistance of the glaze surfaces is improved.
本发明公开了一种多层复合厚釉白瓷及其制作工艺，属于白瓷技术领域，在本发明中多层复合厚釉包括：底层、过渡层及面层；所述底层的釉料包括钾长石、方解石、高岭土、烧高岭、烧滑石、ZnO、SiO2、B2O3；过渡层的釉料包括钾长石、方解石、高岭土、MgO、Al2O3等；所述面层的釉料包括钾长石、方解石、高岭土、TiO2、NaO、CaO、Fe2O3、MgO、Al2O3等；在本发明中采用多层施釉的方法进行制备；在底层至面层三层之间逐步提高釉料的纯度，提高釉面的成型质量；通过控制每层之间的厚度、每层釉水与釉面上料方式，提高釉面的之间的连接强度，在本发明中三层釉面都采用ZnO‑MgO‑B203‑Al2O3‑SiO2系统进行制备，并在体系中增加B2O3提高釉面的耐磨性、硬度，降低釉面的气孔率提高釉面的耐腐蚀性能。
