树种及背面裂隙对多层实木复合地板表板开裂的影响
|
摘要
为了探究多层实木复合地板常用树种、背面裂隙对多层实木复合地板表板开裂的影响,以不同树种、背面裂隙度为影响因素,采用冷热循环试验,以表板裂隙条数为衡量标准讨论了多层实木复合地板表板开裂情况。结果表明:试验采用的三个树种均会产生背面裂隙,黑胡桃表板的裂隙度最小,山核桃表板的裂隙度最大;所用单板背面裂隙度越大,表板开裂越严重。
In order to explore the influence of tree species and back cracks of veneer on the cracking of surface of multilayer parquet, this paper using states different tree species and back crack of veneer as the influencing factors, using the thermal cycle test, measured by the number of cracks on the surface of the board, then discussed the cause of cracking of multi-layer parquet. The results show that the three tree species used in the experiment all produced back cracks the text,the crack on the panel of American walnut is the smallest, and the crack on the panel of pecan is the largest; the crack is the greater on the back of the veneer, the crack of the plate is the more severe.
