MINERALISATION OF HOLDS OR HOLDINGS USED IN CALCIUM ACETATE

摘要

Provided is a method for mineralizing wood and wooden material comprising: i) a first impregnation step, comprising a first impregnation of wood or wooden material with an aqueous solution of potassium oxalate, ii) a first drying step, comprising drying of the wood or wooden material, iii) a second impregnation step, comprising a second impregnation of wood or wooden material with an aqueous solution of calcium acetate iv) a second drying step, comprising drying of the wood or wooden material. Due to the novel mineralization method, the water insoluble products of the impregnation steps penetrate the material deeply and are generated in situ within the cells themselves, in the cell walls and pits and between the xylem cells (primarily fibers and sklereids). The mineralized products are moisture and weather resistant, including under very humid conditions, and exhibit reduced flammability. The products are non-toxic and environmentally safe.
