小径柞木染色工艺的研究

Dyeing technology of small-diameter oak lumber

以小径柞木板材为试验材料,采用碳酸钠、氢氧化钠、硫代硫酸钠和氨水4种染色剂进行了染色效果的对比试验,结果表明,氨水染色效果最好,最佳工艺参数为:质量分数为15%,抽真空,染色时间为12 h。

Four kinds of dyeing materials,sodium carbonate,sodium hydroxide,sodium thiosulfate,and ammonia water were used to conduct oak plank dyed test.Result shows that ammonia water has the best effect for wood dyeing among the four kinds of dyeing materials,The optimal processing parameters of ammonia water dyeing were presented as concentration 15%,vacuumizing,and dyeing time 12 h.
