A kind of elm anticorrosion treatment method

Abstract

The present invention relates to an elm preservative treatment method, which comprises: (1) soaking a wood plate for 2 h with a phosphoric acid solution, and brushing the wood plate surface with a sodium citrate aqueous solution; (2) covering a layer of mixed mud with a thickness of 4 cm on the wood plate surface; (3) carrying out thermal insulation for 48 h on the wrapped wood plate treated in the step (2), wherein edible salt water with a mass fraction of 0.5% is sprayed every 1 h during the thermal insulation process; (4) treating the wood plate treated in the step (3) for 5 h at a temperature of 65 DEG C and a relative humidity of 28%, wherein a potassium nitrate solution with a mass fraction of 0.5% is sprayed every 1 h; and (5) treating the wood plate treated in the step (4) at a temperature of 48 DEG C and a relative humidity of 15%. According to the present invention, with the treatment, the water contents in various positioned of the wood plate achieve the balance, the cracking can be prevented, the quality of the product can be improved, the water absorption capacity of the wood can be reduced, and the preservative property can be improved.
