AI Technical Summary

Technical Problem

Existing impregnated paper-faced plywood is prone to vertical through cracks during hot pressing, leading to structural instability.

Method used

Multiple wooden strips are inserted into the substrate along vertical dividers. The internal fibers of the wooden strips are obliquely extruded to form an inclined texture. The connection is enhanced by upper and lower extrusion layers and bonding layers, resulting in uniform stress distribution. Urea-formaldehyde resin adhesive is used to fix each layer.

Benefits of technology

It improves the vertical compressive strength of the plywood, avoids cracking during hot pressing, and enhances structural stability.

Abstract

一种稳定性强的浸渍胶膜纸饰面细木工板，包括木工芯板、基材和防潮层，两个所述基材固定连接在木工芯板的外壁两侧，两个所述防潮层固定连接在基材的外壁两侧，所述基材的内侧固定嵌入多根木方条，多个所述木方条的之间固定连接有多个竖向分隔块。该稳定性强的浸渍胶膜纸饰面细木工板，木方条采用多个经过机械压力挤压制成的木材纤维块，木方条沿着竖向分隔块间隔出来的孔隙并排插入到基材的内部，木方条内部木材纤维在挤压成型时采用斜向挤压的方式制造倾斜的纹理，这样能够提高木方条竖直方向上的抗压能力，采用整体贴合严密的多层挤压堆叠的细木工板，在后续进行热压机热压时，整体受力比较均匀，抗压能力良好，不易出现竖直方向上的开裂。
