Abstract

一种渗透、色变原木的复原处理方法,涉及木材处理技术领域,其特征在于按如下工艺步骤:1)将渗透、色变原木在浓度为5~10g/L、pH值为10-11的双氧水溶液中进行氧化处理,处理温度:80~98℃,浸渍时间:1~3h;2)经步骤1)处理的原木在浓度为0.4~0.6g/L、pH值为5.5-6.5的脱氧酶溶液中进行脱氧处理,处理温度:55~65℃,浸渍时间:0.8~1.2h。按本发明方法对渗透、色变原木进行复原处理,能使渗透、色变原木薄片恢复到原有天然新鲜砍伐状,而且其纤维素等主要成分结构未受到破坏,使原木薄片在染色过程中均匀着色。该方案处理成本低,还原作用明显,能应用于木材处理的大批量生产。
A recuperation treatment method of penetrating and discolor logs belongs to wood processing technology field. It is characterized by the following steps: 1) oxygenizing the penetrating and discolor logs in hydrogen dioxide solution which concentration is of 5 ~ 10 g / L and pH is 10-11, the treating temperature is 80 ~ 98 degree C and soaking time is 1 ~ 3h; 2) deoxidizing the treated penetrating and discolor logs in step 1) in deoxidization enzyme solution which concentration is 0.4~0.6g / L and pH is 5.5-6.5, the temperature is 55 to 65 degree C and soaking time is 0.8 ~ 1.2h. The invention method recuperates penetrating and discolor logs, can recovery the penetrating and discolor logs thin slices to original natural fresh cut-state, and its main components such as cellulose structure are not damaged, so the logs thin slice can be colored in the process of dyeing uniformly. The program has low dealing cost and the reduction action is obvious, it can be used in the mass production of wood processing.
