三合板

用尿素改性酚醛树脂压制桦木三合板，其所压制的胶合板的各项物理力学性能与常规PF树脂胶合板性能相近，能达到GB/T9846-1988对I类胶合板理化性能的要求；杨木胶合板专用UF树脂胶的研究

The physical properties of the birch plywood bonded with PUF resins is similar to that of the birch plywood bonded with normal PF resins . A study on Urea-formaldehyde Resin Adhesive for Special Use in Production of Poplar Plywood

按材料调湿性能参数b值的大小，本研究对胶合板、刨花板、纤维板、瓷砖、壁纸和聚胺酯饰面椴木三合板等多种材料作了湿度性能区分。

The b values were used to classify the tested interior wall materials such as plywood , particleboard , fiberboard and so on .

通过热解实验，得到了三合板的失重曲线图；计算了其热解动力学参数活化能E和频率因子A；

The weight loss curves of three-ply wood were obtained based on the pyrolysis experiment , and the corresponding kinetic parameters , i.e. activation energy E and frequency factor A , were calculated .

出口：锯成木材、木材成品、尿素、废铁、洋灰、三合板等。

Exports : Sawn Timber , Wood Products , Cement , Plywood , etc.

Bending of Sandwich Beams

实验研究了在一定风速作用下典型的可燃固体材料三合板和五合板上下表面都处于流场中的情况，表面火蔓延的特性；

The studied of characteristics of fire spread over the surface of plywood-one of the typical combustible materials in buildings-on the condition of airflow through both of its surfaces had been described in this paper .

经过3次爆炸，三合板壁面只坏了2块（各1m2面积），试验巷道内部地上枯草、纸片都无燃烧痕迹。

After the ( above ) three explosions , only two boards surfaces were destroyed ( the sectional area is 1 m × 1 m each ), with no burning trace of wilted hays and sheet paper in the internal lane .
