摘要

表面粗糙度是评价木质材料表面质量和加工性能的重要指标之一。以毛白杨（

Populus tomentosa

）单板和酚醛树脂为原料，采用单因素试验制备重组木，探讨压缩率（50%、55%、59%）和施胶量（10%、15%、20%）对重组木干状和湿状表面粗糙度的影响。结果表明，压缩率对干状和湿状表面粗糙度影响显著，且对干状表面粗糙度的影响大于湿状；随着压缩率的增大，重组木的干状表面粗糙度逐渐降低，湿状表面粗糙度逐渐增大；施胶量对干状和湿状表面粗糙度影响显著，且对湿状表面粗糙度的影响大于干状；随着施胶量的增加，重组木干状和湿状表面粗糙度均逐渐降低。与毛白杨单板相比，在压缩率为59%和施胶量为15%时，重组木干状粗糙度参数

a和

z分别降低了79.64%和73.07%，湿状粗糙度参数

a和

z分别降低了62.85%和50.00%。在实际生产过程中，可通过控制压缩率和施胶量调控重组木干状和湿状表面粗糙度，以满足不同应用场景对重组木材料表面粗糙度的需求。

Abstract

Surface roughness was one of the important factors to evaluate the surface quality and processing performance of wood materials. In this study

wood scrimber was prepared with

Populus tomentosa

veneer and phenolic resin using single-factor tests to investigate the effects of

the compression ratios (50%

55%

59%) and resin contents (10%

15%

20%) on the dry and wet surface roughness of wood scrimber. The results showed that the effect of the compression ratio on dry and wet surface roughness was significant; the effect on dry surface roughness was greater than that on wet surface roughness. With the increase in compression ratio

the dry surface roughness of the wood scrimber decreased gradually

and the wet surface roughness increased gradually. The effect of the resin content on dry and wet surface roughness was significant; the effect on wet surface roughness was greater than that on dry surface roughness. With the increase of the resin content

both dry and wet surface roughness of wood scrimber decreased gradually. Compared with

Populus tomentosa

veneer

when the compression ratio was 59% and the resin content was 15%

the dry roughness parameters

a and

z of wood scrimber were reduced by 79.64% and 73.07%

respectively; the wet roughness parameters

a and

z were reduced by 62.85% and 50.00%

respectively. In the actual production process

the dry and wet surface roughness of the wood scrimber can be managed by controlling the compression ratio and resin content to meet the needs of different application scenarios.
