为了评估热带速生树种胶合木材制品的潜在胶合性能，对金莲花胶合性能进行了研究。Nielsen、湿地松Pinus merkusiiJungh et.De.Vriese和印度尼西亚产的相思树Acacia mangium Wild。用聚醋酸乙烯酯乳液(PVAc)、尿素甲醛(UF)、间苯二酚甲醛(RF)和水性聚合物异氰酸酯(API)胶粘剂制备了双层层压板。为了确定胶合层合板的粘结性能，按照日本农业标准对结构胶合层合板在正常条件下和加速老化处理后进行了块剪切试验。为了支持这项研究，还通过接触角测量来研究每种木材的润湿性。结果表明，低密度赤霉菌的粘结性能好于中密度赤霉菌和中密度赤霉菌。而中等密度的粘接性能为P。Merkusii好于中密度A。马吉姆。此外，与a.镁，接触角小，润湿性好。镰刀菌和P.Merkusii具有更好的粘附性，木材表面与粘合剂之间的接触也更紧密。
To estimate the potential bonding performance of bonded wood products from tropical fast-growing tree species, a study on the bondability ofParaserianthes falcatariaL. Nielsen,Pinus merkusiiJungh et. De. Vriese, andAcacia mangiumWilld from Indonesia was conducted. Two-ply laminations were produced using polyvinyl acetate emulsion (PVAc), urea formaldehyde (UF), resorcinol formaldehyde (RF), and water-based polymer isocyanate (API) adhesives. In order to determine the bonding performance, the block-shear test was applied according to the Japanese Agricultural Standard for structural glued laminated timber under normal conditions and after accelerated-aging treatments. To support this study, the wettability of each wood species was also investigated through contact-angle measurement. The results showed that the bonding performance of low-density P. falcataria was better than that of medium-density P. merkusii and medium-densityA. mangium, while the bonding performance of medium-densityP. merkusiiwas better than that of medium-densityA. mangium. Furthermore, compared withA. mangium, the small contact angle and good wettability inP. falcatariaandP. merkusiiresult in better adhesion and more intimate contact between the wood surfaces and adhesive.
