Problems solved by technology

However, under some harsh conditions of use, the anti-corrosion performance of carbonized wood is still lacking, and the mechanical properties of carbonized wood are not ideal. Therefore, in order to better improve the anti-corrosion performance of carbonized wood, it is necessary to improve the current Carbonized wood processing technology to improve the comprehensive performance of carbonized wood

Abstract

The invention discloses a wood preservation carbonizing method. The wood preservation carbonizing method comprises the steps of drying treatment, wherein a cropped wood is subjected to step-by-step drying; carbonizing treatment, wherein the wood subjected to drying treatment is warmed and pre-heated and then carbonized; cooling for temperature reduction, wherein steam is introduced into a carbonizing kiln to carry out temperature reduction treatment; and preservative treatment is carried out, wherein the wood which is subjected to temperature reduction treatment is put into a preservative solution to be soaked. By means of the wood preservation carbonizing method, the plant preservation solution is adopted to carry out secondary preservative treatment on the carbonized wood, the preservative performance of the wood is greatly enhanced, the wood can adapt to the harsh external environment, and meanwhile preservation treatment is environmentally friendly, healthy and free of toxicity; and by arranging primary carbonizing, secondary carbonizing and tertiary carbonizing, cellulose, hemicelluloses and lignin in the wood are sufficiently carbonized, carbonizing is more sufficient, and the carbonizing effect is better.

Description

Technical field [0001] The present invention relates to the field of carbonized wood, and more specifically, to a method for preserving and carbonizing wood. Background technique [0002] Carbonized wood is a homogenous carbonization treatment of wood at high temperature without any chemical agent, so that the wood surface has a dark brown beautiful effect, and has anti-corrosion and anti-biological attack effects. Its water content is low, and it is not easy to absorb water. Stable, non-deformed, completely degreasing and non-fat spilling, good heat insulation performance, simple construction, convenient painting, no special odor, it is an ideal indoor and sauna material, becoming a new popular trend in bathroom decoration; it is anti-corrosive and insect-resistant Moth, deformation and cracking resistance, and high temperature resistance have also become ideal materials for outdoor swimming pool landscapes. However, in some harsh environments, the corrosion resistance of carbo...
