| 摘 要： | 利用响应面法分析研究了经微孔处理后的杨木单板的胶合性能。通过对杨木单板进行微孔处理,可使胶黏剂通过微孔渗入单板体内,增加杨木单板的本体强度,同时也可使相邻胶层透过微孔形成一体而增加单板的胶合强度等,以期制造出一种高性能的地板基材。结果表明:在试验范围内,随微孔孔径增大,孔距减小和施胶量的增加,其胶合强度增加;随热压压力增加,胶合强度先增强,当压力超过0.8 MPa,胶合强度反而降低。

| Abstract: | We studied the bonding properties of poplar veneer punched with micro-holes by using response surface experiment. The permeability of poplar veneer increased after micro-hole punching.The adhesive could penetrate into the veneer through these micro holes, and the poplar veneer was strengthened.Through micro holes, the neighboring glue lines formed a whole to increase the bonding strength of veneers.Expecting to produce a high performance floor material.The bonding strength of poplar plywood increased with the increasing of micro-hole diameter,resin content , and the decreasing of holes distance.With the increasing of hot pressing pressure, the bonding strength was improved firstly, however, it declined when the pressure exceeded 0.8 MPa. |
