摘要

为了提高软木材质的均匀性,去除杂质,制定软木的膨化处理工艺,对陕西产软木进行先蒸煮、后烘焙处理,分析处理前后软木的质量、体积及表面宏观构造的变化。确定优化膨化工艺为:先在体积分数为10%的甲醇水溶液中加压蒸煮1 h,再在240℃下烘焙2 h。处理后软木的体积膨胀明显,杂质部分去除。

Abstract

The authors evaluated and improved the cork expansion process by removing impurities and adding value to it.After cork specimens were boiled and dried under various conditions,their weight,volume,and surface characteristics were evaluated.An optimal expansion process was determined based on the results.This included boiling the samples in a 10% methanol solution under pressure for 1 hour and baking them at 240 ℃ for 2 hours.
