【摘要】 对自然气候条件下塑木复合材料的宏观质量变化及颜色变化进行了分析,同时采用差示扫描量热技术对其热学变化特征进行了分析。结果表明,水分是导致材料吸湿增重的主要原因,其对材料分子结构的变化有着重要的影响,是影响材料耐候性的关键因素。更多还原

【Abstract】 The weight and color change of wood plastic composites was analysed and the thermal characteristic was studied by using differential scanning calorimetry under natural weather.The results showed that the reason of the weight gain of the material was moisture absorption.Water had some important effects on molecular structure of the material,and it was the key factor affecting the weathering of the material.更多还原
