Preparation process of porous hollow ceramic adsorption ball

DU WENZHONG

The invention discloses a preparation process of a porous hollow ceramic adsorption ball, belongs to the field of ceramic materials. The preparation process of the porous hollow ceramic adsorption ball can obtain a hollow porous ceramic ball through the cooperative use of a reticular steel ball and an internal false solid bag. Compared with the prior art, the process can effectively avoid the problems that the ceramic utilization rate is low due to the fact that the porosity of the center of the ball body is small, waste of ceramic materials is reduced, meanwhile, inert gas is introduced intothe ceramic ball semi-finished product in the preparation process, the reinforcing hard ball collides with the inner wall of the ceramic ball semi-finished product, reinforcing fiber particles are released, and in combination with rapid cooling operation, the reinforcing fiber particles enter the pores of a ceramic material layer along with the inert gas and are fixed, on one hand, the inert gas can increase the pore volume in the center of the ceramic material layer, so that the uniformity of the pores of the obtained porous hollow ceramic adsorption ball is improved, and on the other hand, the reinforcing fiber particles can remarkably improve the adsorbability of the interior of the ceramic material layer to oil stains.

本发明公开了一种多孔空心陶瓷吸附球的制备工艺，属于陶瓷材料领域，一种多孔空心陶瓷吸附球的制备工艺，通过网状钢球和内假实心囊的配合使用，可以得到空心的多孔陶瓷球，相较于现有技术，有效避免因球体中心处孔隙量较少造成的陶瓷利用率低的问题，降低对陶瓷材料造成的浪费，同时在制备过程中通过向陶瓷球半成品内部通入惰性气体，使补强硬球与陶瓷球半成品内壁发生碰撞并释放补强纤维粒，配合急降温操作，补强纤维粒随惰性气体进入到陶瓷材料层孔隙内并被固定，一方面惰性气体可以增加陶瓷材料层中心处的孔隙量，从而提高得到的多孔空心陶瓷吸附球孔隙的均匀性，另一方面补强纤维粒可以显著提高陶瓷材料层内部对油污的吸附性。
