蜂窝浸胶-烘干-固化质量模型研究

Study on Mass Model of Honeycomb's Dipping-Drying–Curing

通过试验测试研究了酚醛树脂溶液密度与固含量的关系,采用热失重分析法研究了固含量与烘干及固化后酚醛树脂质量的关系,建立了酚醛树脂溶液密度与固含量的关系式,提出了酚醛树脂烘干及固化质量模型。经试验验证,模型具有较好的重复性,计算值与实测值偏差在±2kg以内,相应的蜂窝块密度偏差可控制在±4.2%以内。

The relationship between density and the solid content of phenolic resin is studied. The relationships between the solid content and resin mass after drying and curing are studied by thermal gravimetric analysis （TGA）. A theoretical formulas between density and the solid content of phenolic resin is established, the drying mass model and curing mass model are proposed. Experimental verification shows that the models are well repeatable. It states that the deviation between the output of the mass model and real value is within±2kg, accord- ingly the deviation of honeycomb density can be controlled within ±4.2%.
