摘要
以树脂增重率来表示脲醛树脂的相对浸渍量,研究脲醛树脂浸渍量与泡桐抗弯强度的关系。结果表明:泡桐的抗弯弹性模量和抗弯强度在一定范围内随树脂增重率的增加而提高,经过脲醛树脂浸渍后,泡桐的破坏极限有所提高,抗弯破坏过程呈波动下降的特性。
The name of WPG（weight percent gain） is used in the study on increasing the bending strength of paulownia by urea-formaldehyde impregnation. The results show that the modulus of elasticity in static bend and the bending strength are enhanced with WPG inserease. After being impregnated by urea-formaldehyde（UF）, the broken limit of paulownia is enhanced and the broken progress is wavily declined.
