室温下不同化学试剂对“唐山骨质瓷”釉面侵蚀度的定性及定量影响研究

The Quantitative and Qualitative Analyses of Glaze Erosion Strength by Different Chemical Reagent to Geographical Indication Protection Products Tangshan Bone China in Room Temperature

针对"唐山骨质瓷"地理标志产品特定的原料配比和生产工艺,选取6家不同企业生产的36件白瓷8吋平盘作为实验样品;在既定的温湿度条件下,使用酸、碱、盐、漂白剂、染色剂及消毒剂6种化学试剂对骨质瓷样品釉面持续作用一定时间后,对受侵蚀前后的釉面状态进行定性分析,并对白度和光泽度的变化情况进行定量测试,研究不同化学试剂侵蚀作用的强弱。推导得出如下结论:不同试剂对同一骨质瓷样品釉面的侵蚀强度各异,其中碱的腐蚀作用强于酸,染色剂对釉面白度和光泽度的影响大于盐类和消毒剂;不同企业生产的骨质瓷耐同一种试剂腐蚀的性能有所不同。由于测量机理不同,针对骨质瓷釉面的微小变化,白度和光泽度的波动幅度存在一定差异。本研究成果可为企业改进相关生产工艺、完善产品质量控制提供科学依据。

This paper according to the requirements of the unique production process of the Tangshan bone China geographic indication products, specified 36 pieces of bone China 8 inch flat produced by 6 different factories as the experimental sam- pies. After using 6 kinds of chemical reagents such as acid, alkali, salt, stain and disinfectant eroded continuously on the a- bove samples glaze for a certain period of time under the given conditions of temperature and humidity, tested glaze white- ness and gloss of samples qualitatively. By measuring the changes of whiteness and luster after glaze erosion of samples, analyzed degree of the erosion quantitatively. Derived the following conclusions： the strength of glaze corrosion caused by different chemical reagents to bone china samples produced from the same factories were different. The corrosion effect of alkali is stronger than that of acid, and the corrosion effect of stain is stronger than that of salt and disinfectant for bone china glaze white and glossiness. The corrosion effect of each chemical reagent used for bone china samples produced by dif- ferent factories is different. The corrosion effect of each chemical reagent is different for bone china samples produced by different factories. Due to different measurement principle, the rangeability of hone china glaze whiteness and luster with the glaze state changes is different. The research results can provide scientific reference to the manufacturing factories for improving the production process and the quality control.
