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.
