Rapid estimation of the shelf life of rubber vulcanizates by the chemical stress relaxation method 用化学应力松弛法快速估算橡皮材料的贮存保险期
Filler effect on chemical stress relaxation of silicone rubber 填料对硅橡胶化学应力松弛的影响
The molecular chain fatigue failure mechanism of above curing systems was discussed from compression heat build-up, continuous chemical stress relaxation and intermittent chemical stress relaxation. Their failure characteristic parameters β and C0 were derived. 从生热、连续和间歇应力弛豫等行为上讨论了3种硫化体系共混物的疲劳断裂机理,并给出了各体系共混物疲劳断裂特征参数β和C0。
The contribution of chemical shrinkage to curing stress development and the residual stress relaxation characterized by glass transition region were considered. The four models are: A model describing the temperature field. 在本模型中考虑了化学收缩对残余应力史的贡献,并考虑了以玻璃化转变区为应力释放区的应力松弛过程。
Mathematical model for chemical stress relaxation of rubbers in aging 橡胶老化的化学应力松弛数学模型
Chemical stress relaxation of low density polyethylene cross-linked by γ-irradiation γ-辐照交联聚乙烯的化学应力松弛
The chemical stress relaxation of the vulcanizates can be used to evaluate the aging properties of rubber because the different stress relaxation rates of various vulcanizates reflect their different aging properties. 各种橡胶的应力松弛速率的不同,反映出其耐老化性能的不同,因而硫化橡胶的化学应力松弛可以用来评价橡胶的耐候性。
