Abstract
A ceramic membrane is provided, which may include glass, incinerator fly ash, kaolin and palygorskite. The weight percent of the glass may be 30˜60 wt %. The weight percent of the incinerator fly ash may be 5˜30 wt %. The weight percent of the kaolin may be 0˜50 wt %. The weight percent of the palygorskite is 0˜30 wt %.
Claims21
A ceramic membrane, comprising:
- a glass, wherein a weight percent of the glass is substantially 30˜60%;
- an incinerator fly ash, wherein a weight percent of the incinerator fly ash is substantially 5˜30%;
- a kaolin, wherein a weight percent of the kaolin is substantially 5˜50%;
- and
- a palygorskite, wherein a weight percent of the palygorskite is substantially 5˜30%.
A ceramic membrane manufacturing method by recycling incinerator fly ash, comprising:
- providing a glass, an incinerator fly ash, a kaolin and a palygorskite, wherein a weight percent of the glass is substantially 30˜60%, a weight percent of the incinerator fly ash is substantially 5˜40%, a weight percent of the kaolin is substantially 5˜50% and a weight percent of the palygorskite is substantially 5˜30%;
- executing a water-extraction pre-process to process the incinerator fly ash to generate a water-extracted fly ash;
- mixing and pressing the glass, the water-extracted fly ash, the kaolin and the palygorskite to obtain a green body;
- and
- performing a sintering process to sinter the green body to obtain a ceramic membrane.
