Nanometer ZrO2-loaded microcrystalline ball, and preparation method and application thereof
The invention relates to a scale restraining material, especially to a scale restraining material with ZrO2 as a raw material. The invention discloses a nanometer ZrO2-loaded microcrystalline ball, and a preparation method and application thereof. The nanometer ZrO2-loaded microcrystalline ball comprises a ball body made of Al2O3.ZrO2; a ZrO2 layer is arranged on the surface of the ball, and Al2O3.ZrO2 composite powder is used as a precursor. The preparation method comprises the following steps: decreasing granularity through mechanical milling and then carrying out dry pressing and hot-press sintering so as to obtain the ball body; alternatively cleaning the ball body with ethanol and water and drying the ball body for subsequent usage; sprinkling an aqueous Zr(NO3)4 solution onto the surface of the treated ball body; sprinkling ammonia water onto the ball body treated in the previous step and then drying the ball body; and calcining the ball body in a muffle furnace. The nanometer ZrO2-loaded microcrystalline ball is capable of eliminating hardness (scale) in water, has the advantages of easy controllability of reaction, easy operation, easy maintenance, etc., is one of the effective approaches for inhibiting scaling of drinking water and has wide market development prospects.
