1)  flex fatigue life
耐屈挠龟裂性能
1.
The hardness,mechanical properties,abrasion resistance,and flex fatigue life of carbon black/montmorillonite(MMT)/SBR nano-composites were investigated with low level(0~5 phr)MMT replacing the same level of carbon black.
采用少量(0~5份)蒙脱土(MMT)等量替代炭黑,考察炭黑/MMT/SBR纳米复合材料的硬度、强伸性能、耐磨性能和耐屈挠龟裂性能
2)  flex cracks
屈挠龟裂
3)  flexing resistance
耐屈挠性能
1.
The results showed that the scorch safety of polybutadiene rubbers was good;the tensile strength,tear strength,thermal aging property and wet traction of MVBR were better;generally,the wear resistance,flexing resistance and dynamic property of BR were excellent,and BR was suitable for tread compound application.
结果表明,聚丁二烯橡胶的焦烧安全性较好;中乙烯基聚丁二烯橡胶拉伸强度和撕裂强度较大,耐热空气老化性能和抗湿滑性能较好;BR耐磨性能、耐屈挠性能和动态力学性能较好,适合用于轮胎胎面胶。
4)  flex cracking resistance
抗屈挠龟裂
5)  flex fatigue property
耐屈挠疲劳性能
1.
The results showed that when the CTPI was added to CR/TPI blend,the scorch time and optimum curing time of CR/TPI blend reduced,the compatibility between TPI and CR increased,and then the dispersity of carbon black and the flex fatigue property were improved.
结果表明,在CR/TPI并用胶中加入CTPI可缩短胶料的焦烧时间和正硫化时间,改善TPI与CR的相容性,从而改善胶料中炭黑的分散性,显著提高胶料的耐屈挠疲劳性能。
6)  flex stiffness
耐屈挠性
补充资料:龟裂
分子式:
CAS号:

性质:又称龟裂。皮肤、土壤及材料等产生的小裂纹现象。在电池工业铅酸蓄电池的极板,特别是负极板在化成后由于活性物质的体积变化而出现的小裂纹。严重的皲裂导致极板强度和电性能降低,甚至出现活性物质从板栅上脱落的现象。在负极材料中加入添加剂如木素、硫酸钡、松香等的目的是改善负极的电性能,但也减少了皲裂。负极中氧化铅(PbO)在化成过程中变为铅(Pb),它占据的体积要收缩25%,所以固相所占体积会相应减少,同时孔的体积增加。轻微的皲裂并不影响极板的强度和电性能。
