| 摘要: |
| 采用窑式常压过热蒸汽方法对栎木地板坯料进行超高温热处理，研究了相对湿度在40%～90%变化范围内，热处理工艺对栎木地板尺寸稳定性的影响。结果表明：热处理并未显著减小木材干缩系数，但能显著减小使用环境温湿度变化对木材含水率变化的影响，从而提高栎木地板使用时的稳定性。为满足地热采暖使用条件，宜采用190℃热处理温度。 |

| Abstract: |
| The Quercus mongolica unfinished flooring strips was heat-treated with super-high temperature in atmospheric-pressure super-heated steam kiln method. The influence of treatment on the dimensional stability of Quercus mongolica unfinished flooring strips were studied when relative humidity varied between 40% and 90％. The results showed that heat-treatment does not significantly reduce shrinkage coefficient of wood, but it can remarkably reduce the influence of environmental temperature and relative humidity variations on wood moisture content, accordingly increase the stability for use of Quercus mongolica flooring. 190℃ heat treatment should be used to meet the working conditions of geothermal heating. |
