| 摘 要： | 采用V313和ASTM快速老化法,研究意大利杨定向刨花板在老化试验中的性能变化规律,以及施胶量对定向刨花板耐久性的影响。试验证明:定向方向强度下降大于垂直方向;施胶量增加,酚醛胶刨花板的耐久性提高,而脲醛胶刨花板的耐久性与施胶量关系不大,ASTM快速老化试验条件剧烈,只适用于酚醛胶定向刨花板。 |

ACCELERATED-AGING TEST OF ORIENTED STRAND BOARD |
|
| Abstract: | This paper deals with the changes of the MOR and MOE of OSB in acc-elarated-aging tests and the influence of resin content on durability of OSB. The results showed thate MOE and MOR in parallel divection decreased more than in perpendicular direction; With increase of PF resin content, the durability of OSB was built up, but UF resin content had little effects on OSB durability; ASTM aging test method was only suitable for PF OSB. |
