Device for preparing porous ceramic and method for preparing porous ceramic by using polystyrene foam particles
The invention provides a device for preparing porous ceramic and a method for preparing porous ceramic by using polystyrene foam particles, and belongs to the technical field of porous ceramic. The device comprises a foaming cylinder body 1 with a lower opening and a ceramic slurry cylinder body 2 communicating with the foaming cylinder body 1 through a metal net 6, wherein the metal net 6 is arranged at the joint of the foaming cylinder body 1 and the ceramic slurry cylinder body 2, the foaming cylinder body 1 is provided with an upper cover 3, the upper cover 3 is provided with a gas inlet 4, and a pressurizing piston 5 is arranged at a lower opening of the ceramic slurry cylinder body 2. The device is simple in structure, the porous ceramic is prepared by using the polystyrene foam particles as a pore forming agent by using the structure, the cost is low, and the market competitiveness is high; the specific volume of the polystyrene foaming particles is low, and smoke pollution generated in the roasting process is small; and the porosity of the porous ceramic can be accurately controlled by adjusting the compactness of the polystyrene foamed particles and the introduction time of the foaming gas.
本发明提供了一种制备多孔陶瓷的装置和一种用聚苯乙烯发泡颗粒制备多孔陶瓷的方法，属于多孔陶瓷技术领域。本发明提供的装置包括下敞口的发泡缸体1和通过金属网6与发泡缸体1连通的陶瓷浆料缸体2，所述金属网6设置在所述发泡缸体1和陶瓷浆料缸体2的交接处；所述发泡缸体1设有上盖3，所述上盖3设有气体入口4；所述陶瓷浆料缸体2的下敞口处设有加压活塞5。本发明提供的装置结构简单，使用此结构利用聚苯乙烯发泡颗粒为造孔剂制备多孔陶瓷，成本低，市场竞争力高；其中聚苯乙烯发泡颗粒比容低，焙烧过程中产生的烟气污染较小。且此法能够通过调节聚苯乙烯发泡颗粒的紧实度和发泡气体的通入时间来精确控制多孔陶瓷的孔隙率。
