摘要

在工业陶瓷用ZrSiO4釉的基础上，研制了一种新型光活性氧化物釉。该开发旨在生产光滑的釉，以减少对瓷器的污染，并增加超亲水润湿性能，从而更容易清洁。用轮廓术、原子力显微镜、x射线衍射和扫描电镜对釉料进行了表征。测定了紫外光下的反应性、暗中和辐照后的润湿角以及亚甲基蓝的降解情况。含有tio2的样品在黑暗和紫外线照射下都没有改善润湿。然而，与工业ZrSiO4瓷砖相比，在含有大量污染物(如芥末)的情况下，其清洁性能有所提高。用zno代替zrsio4获得了更有希望的结果。在紫外光照射下，该釉料表面粗糙度小于20 nm，具有超亲水润湿性。

Superhydrophilic ceramic glazes for sanitaryware

Based on industrial ZrSiO4 glazes for sanitaryware, a new glaze with photoactive oxides was developed. The development aimed to produce a glaze that is smooth in order to decrease contamination of the ware and increase superhydrophilic wetting behaviour for easier cleanability. The glazes were characterized with profilometry, atomic force microscopy, x-ray diffraction and scanning electronmicroscopy. For reactivity under UV light, the wetting angles in the dark and after irradiation, aswell as the degradationofmethylene blueweremeasured. SampleswithTiO2 showed no improvement in wetting, neither in the dark, nor under UV irradiation. However, compared with the industrial ZrSiO4 tile, the cleaning properties were improved in the case of bulk contaminants likemustard. Evenmore promising resultswere achieved by replacingZrSiO4withZnO.The glazes developed in thiswork showed surface roughness of less than 20 nm and superhydrophilic wetting under UV illumination.
