[求助] 求助炭黑方面的几句文献翻译(中译英)

范德华网络理论
该理论假设炭黑聚集体内部的炭黑粒子是沿着拉伸方向平行排列的,粒子表面被聚合物全
部覆盖,连接聚集体和聚集体链的长度存在着一定的分布,以炭黑聚集体和连接聚集体的
聚合物一起作为基本的增强体,总应力由未填充橡胶网络的应力和炭黑聚集体网络的应力
2部分组成。
该理论认为在橡胶变形时,在填料粒子之间的吸溜胶的形变远大于宏观形变,所以填料粒
子聚集体可以产生内部滑移,填料粒子的滑移是塑性形变,是熟化胶产生Mull ins效应的原
因。
椽胶的增强来自于对橡胶粒子分开的反抗。橡胶的增强效果与吸留胶的厚度分布有关。
粒子和粒子之间的作用是范德华力,粒子和聚合物基质之间的结合力较强。
使粒子分开的临界应力是粒子之间的范德华应力。

Van der waals network theory

The theory assumes that carbon black particles inside the carbon black aggregates are arranged in parallel along the tensile direction. The particle surface is completely covered by polymer, and there are certain distributions on lengths of linking aggregates and aggregate chains. As the basic reinforcement together with the carbon black aggregates and polymer connecting the aggregates, the total stress is composed by two parts: the stress of the unfilled rubber network and the stress of carbon black aggregates network.

According to the theory, deformation of absorbing rubber among the filler particles far outweighs macroscopic deformation when rubber becomes deformed. Thus, the filler particle aggregates can produce interior slip, and slip of the filler particles is the plastic deformation and the reason of Mullins effect produced by curing glue.

The enhancement of rafter rubber is from the resistance of rubber particle separation. The enhanced effects of rubber are related to thickness distributions of absorbing rubber. The interaction among the particles is Van der waals force, and binding force is more powerful between particles and polymer matrix. The critical stress which makes particles separated is Van der waals stress among the particles.
