摘要 |
The invention relates to a method for producing a body including: preparing a granular mixture including: a) at least 90 wt % of mineral oxide grains; b) 0.3 to 3 wt % of resin polycondensed with formaldehyde and/or the derivatives thereof, the percentage being calculated in terms of dry resin extract; c) 0.001 to 1 wt % of a hardening agent, the percentage being calculated in terms of dry hardener extract; d) 0.005 to 0.35 wt % of a formaldehyde scavenger compound; and e) 0.2 to 3 wt % of water; contacting said granular mixture with a surface of a forming tool; and insufflating a gas flow at 50 to 380 degrees into the granular mixture for 1 to 300 seconds in order to at least partially harden said mixture, the formaldehyde scavenger being carbohydrazide. |
