Abstract:
1. A process for making a bamboo filament slab floor by opposite directional hot pressing, including following sequential procedures: splitting and sawing bamboo as bamboo sheets, removing the outer and inner surface layers of the bamboo sheet; shredding the bamboo sheets as bamboo filaments; anti-corrosion treatment for the bamboo filaments by directly stewing or wet carbonizing; primary drying for the bamboo filaments; sizing treatment for the bamboo filaments, fully soak the bamboo filaments into glue pool by water-resistant glue, the glue content is 15%˜20%; secondary drying the bamboo filaments; molding bamboo filaments, pave the bamboo filaments in a crisscross pattern with several layers into molding boards having upper and lower and side faces which can horizontally move; compressing treatment for the bamboo filaments, first, opposite directional hot pressing, including positive pressing on upper and lower opposite faces and side pressing on left and right opposite side faces, followed by cooling under pressure state and pressure relief procedure at last; said positive pressure is 50˜100 MPa, said side pressure is 10˜50 MPa, a temperature of said hot-press is 130˜150° C. and a period of said hot-press 15˜60 minutes; balancing treatment for formed bamboo filament slab floors, which are stored in a dry natural environment indoors for five to ten days or more to remove remaining stress, and to make water content even distributing in the filament slab floors.
