Selenium-rich purple sand ceramic material and porous selenium-rich purple sand ceramic product
The invention discloses a selenium-rich purple sand ceramic material and a porous selenium-rich purple sand ceramic product, and relates to the technical field of selenium-rich purple sand ceramic materials and processing thereof. The selenium-rich purple sand ceramic material is prepared from ceramic powder, resin slurry and auxiliaries, wherein the ceramic powder comprises purple sand powder and a selenium source, and comprises the following components in percentage by mass: 55%-70% of purple sand powder, 0.1%-10% of selenium source, 25%-35% of resin slurry and 4%-15% of auxiliaries. In the sintering process of the selenium-rich purple sand ceramic material provided by the invention, rich and compact micropores are formed due to the dual effects of volume shrinkage and degreasing, and the porosity is greatly improved compared with that of the selenium-rich purple sand ceramic material only depending on volume shrinkage, so that the contact area of water and selenium-rich purple sand ceramic in the water soaking process is increased, and the service life of the selenium-rich purple sand ceramic material is prolonged. On one hand, stable and long-term release of selenium in the water can be effectively promoted, and on the other hand, the use amount of a selenium source can be effectively reduced, so that overhigh selenium content in the water caused by sudden release is avoided, the selenium in the water is maintained in a reasonable range for a long time, and harm caused by excessive selenium is avoided while selenium is effectively supplemented. The invention solves the problem of selenium-rich purple sand ceramic products in the prior art, and effectively expands the application prospect of purple sand.
本发明公开一种富硒紫砂陶瓷材料及多孔富硒紫砂陶瓷制品，涉及富硒紫砂陶瓷材料及其加工技术领域。本发明的富硒紫砂陶瓷材料由陶瓷粉料、树脂浆料和助剂构成；其中陶瓷粉料包括紫砂粉末和硒源，按质量百分数计包括紫砂粉末55％‑70％，硒源0.1％‑10％，树脂浆料25％‑35％，助剂4％‑15％。本发明提供的富硒紫砂陶瓷材料在烧结过程中，由于本身的体积收缩以及脱脂双重作用，形成丰富且致密的微孔，且孔隙率与仅依靠体积收缩相比大幅提高，由此增加了泡水过程中水与富硒紫砂陶瓷的接触面积，一方面能有效促进其中硒元素的稳定、长期释放，另一方面可以有效减少硒源的用量，避免突释造成水中硒含量过高，使得水中硒元素长期维持在合理范围，有效补充硒的同时避免过量硒带来的危害。本发明解决了现有技术中富硒紫砂陶瓷制品的问题，有效拓展了紫砂的应用前景。
