一个粘结体系的粘按强度和复合材料的力学性能受到树脂液对固体表面的湿润程度的影响。一般来说,湿润的程度取决于树脂液和被粘固体表面的物理、化学的性质,是一个复杂的多因素问题。本文根据界面化学的湿润理论和对具有一定粘度的树脂液同实际的固体材料表面的毛细现象的分析。得到γs=γL,γsI=0,η=0,t(树脂液可流动的时间)极大和受压浸渍是湿润的最佳条件。
The bond strength of a bonded system and the mechanical properties of the composite are affected by the degree of wetting of the resin surface to the solid surface. In general, the degree of wetting depends on the physical and chemical properties of the resin fluid and the surface of the adherend, and is a complex multi-factorial problem. In this paper, based on the theory of interface chemistry wetting and resin solution with a certain viscosity with the actual capillary surface of solid material analysis of the phenomenon. Obtained γs = γL, γsI = 0, η = 0, t (resin flow time) and pressure impregnation is wetting the best conditions.
