Abstract
A manufacturing method for ceramic tile products comprises the steps of providing a green body and sintering the green body. The green body has a composition comprising gypsum ranging from 15 to 35% weight of the green body and a subsidiary material ranging from 65 to 85% weight of the green body.
Claims13
A manufacturing method for ceramic tile products, comprising the steps of:
- providing a green body, the green body having a composition comprising phosphogypsum ranging from 15 to 35% weight of the green body and a subsidiary material ranging from 65 to 85% weight of the green body;
- and
- sintering the green body;
- wherein in the step of providing the green body comprising the steps of:
- providing the phosphogypsum and the subsidiary material;
- grinding the phosphogypsum and the subsidiary material to sufficiently pulverize and mix together a mixed powder through a dry grinding process without the addition of water;
- granulating the mixed powder to obtain a fine granular material;
- processing the fine granular material through an optimization process;
- drying the fine granular material to control the moisture content of the fine granular material to about 6 to 8%;
- and
- shaping the fine granular material into the green body through a molding process.
