| 摘 要： | 对较厚木材进行真空浸注染色研究,探究染色工艺因子对染色厚度的影响.结果表明:抽真空对木材染色有促进作用,随着真空度的增加,可以明显提高染色深度;不同材种木材,染色深度差异较大,杨木染色速度快,渗透深度大,杉木次之,泡桐木材渗透最差,染色深度浅.同种木材的径向染色液渗透速度快,弦向较慢.渗透剂PTCH有利于提高染色液润湿性能.含水率对染色深度影响明显,染色深度均随着含水率的增大而减少.浸染时间对染色深度有明显影响,染色深度随着浸染时间的延长而增加.

| Abstract: | An experiment was conducted to study the effects of factors affecting dyeing depth using impregnated thick woods with vacuum treatment as testing materials.Result showed that vacuum treatment played a promotive role in deep dyeing of wood,and the dyeing depth increased with vacuum degree increasing.There was a significant difference in dyeing depths of woods from different tree species.The dyeing depth of poplar wood was the highest,and then followed by Cunninghamia lanceolata wood and paulownia wood from h... |
