Claims13
A method for forming an artificial turf infill material, the method comprising:
- providing a zeolite ore;
- selecting from the zeolite ore a microporous zeolite mineral using a selection criterion on a specific surface area of the mineral to provide the artificial turf infill material, wherein the microporous zeolite mineral has a grain size smaller than 0.3 mm and the selection criterion comprises selecting the zeolite mineral having a porosity between 15% to 20% and a maximum specific surface area of 20 m2/g corresponding to a release of water for ambient temperatures between 40° C. and 60° C.
A method for forming an artificial turf infill material, the method comprising:
- providing a zeolite ore;
- selecting from the zeolite ore a microporous zeolite mineral to provide the artificial turf infill material, wherein the microporous zeolite mineral has a porosity between 15%-20%, wherein the microporous zeolite mineral has a grain size smaller than 0.3 mm, and wherein a moisture level in the mineral is smaller than 6%.
A method for forming an artificial turf infill material, the method comprising:
- providing a zeolite ore;
- selecting from the zeolite ore a microporous zeolite mineral using a selection criterion on a specific surface area of the mineral to provide the artificial turf infill material, wherein the selection criterion comprises selecting the zeolite mineral having a porosity between 15% to 20% and a maximum specific surface area of 20 m2/g corresponding to a release of water for ambient temperatures between 40° C. and 60° C.,
- wherein the artificial turf infill material comprises a layer of the microporous zeolite mineral and a layer of sand, wherein the layer of the microporous zeolite mineral overlays the layer of sand.
