Abstract
A process for the production of shaped articles from wood particles, especially chipboards, wherein the basic cellulosic material comprised of wooden articles is admixed with at least one mineralizing agent, water, and a hydraulic binder such as cement, the mixture is shaped and then pressed at a constant temperature above the freezing point; the process being characterized in that the water required for activating the hydraulic binder is added and admixed with the basic cellulosic material before the addition of the mineralizing agent and the hydraulic binder.
Claims8
In a process for making shaped articles of a wood material bonded with hydraulic cement wherein at least one mineralizing agent, water and a hydraulic cement are added to the cellulosic material comprised of wood particles, and the thus-prepared mixture is then shaped and pressed at a constant temperature above the freezing point, the improvement comprising:
- adding the amount of water, required for the hydraulic cement, to said cellulosic material and mixing said water therewith;
- thereafter adding said at least one mineralizing agent, reactive with a component of said cement, to said cellulosic material and then adding said hydraulic cement to the resulting wet cellulosic material.
