摘　　要：利用热重-差示扫描热量法联用测得造纸污泥分别与脲醛树脂胶粘剂(UF)和酚醛树脂胶粘剂(PF)两种胶合材料在加热过程中的热反应特征。通过分析可得出,造纸污泥在加热过程中没有明显吸、放热现象,表现出良好的耐热性。在加热过程中UF有明显的吸、放热现象,而与UF混合物则没有明显的热反应特征。造纸污泥与PF混合物在加热过程中有吸、放热反应,较之UF混合物热反应特征更明显。The thermal-reaction among paper mill sludge and urea-formaldehyde （UF） , phenol-formaldehyde （PF） by the thermogravimetry-diKerencial were tested. The results showed that there were no obvious heat absorption and leak effects when the paper mill sludge was heated. In the course of heating, the UF presented significant absorpting and leaking effects, but the thermal reaction was not significant when the paper mill sludge blended with UF,while it was significant when mill sludge blended with PF.
