Treatment method of waste SCR denitration catalyst, composite opacifier for ceramic, ceramic glaze and ceramic product
The invention provides a treatment method of a waste SCR denitration catalyst, a composite opacifier for ceramic, ceramic glaze and a ceramic product, and relates to the technical field of treatment of waste SCR denitration catalysts. The treatment method comprises the following steps: mixing a pretreated waste SCR denitration catalyst, wollastonite, calcium carbonate and an optional dispersant, and crushing to obtain the composite opacifier for ceramic, wherein the waste SCR denitration catalyst is used as a raw material of the composite opacifier for the ceramic, so that the problem of reutilization of the waste SCR denitration catalyst is solved, the utilization value of the waste SCR denitration catalyst is greatly improved, and meanwhile, the production cost of the composite opacifierfor the ceramic is greatly reduced; and meanwhile, the obtained composite opacifier for the ceramic has good opacifying performance when in use. The invention also provides thecomposite opacifier forceramic. The composite opacifier is prepared by adopting the treatment method of the waste SCR denitration catalyst.
本发明提供了一种废弃SCR脱硝催化剂的处理方法、陶瓷用复合乳浊剂、陶瓷釉料和陶瓷制品，涉及废弃SCR脱硝催化剂处理技术领域。该处理方法通过将预处理后的废弃SCR脱硝催化剂、硅灰石、碳酸钙与任选地分散剂混合后粉碎，得到陶瓷用复合乳浊剂；其中，废弃SCR脱硝催化剂作为陶瓷用复合乳浊剂的原料使用，不但解决了废弃SCR脱硝催化剂的再利用的问题，还使得废弃SCR脱硝催化剂的利用价值大为提升，同时又大大降低了陶瓷用复合乳浊剂的生产成本，同时所得到的陶瓷用复合乳浊剂在使用时具有良好的乳浊性能。本发明还提供了一种陶瓷用复合乳浊剂，采用上述废弃SCR脱硝催化剂的处理方法制得。
