分子链滑动理论 分子链滑动理论认为，吸附在炭黑表面的橡胶分子链有一定的活动能力。初始状态下，长短不等的橡胶分子链通过物理吸附附着在炭黑分子表面，当有应力作用时，橡胶分子链在炭黑粒子表面滑动，炭黑粒子间伸长的多数链段承受应力；随着应力的增大，橡胶分子链会继续滑动，使得橡胶链段髙度取向，促使应力重新分布，因而承担的应力和模量增大，阻止了由于分子链集中而引起的分子链断裂；外力撤销后，胶料收缩，经过长时间恢复后，由于橡胶链段的热运动，吸附和解析达到了新的动态平衡，使炭黑粒子间橡胶胶料分子链间的长度重新分布，胶料又恢复或接近于原始状态。 |

According to the theory of sliding of molecular chains, rubber chains that adsorb on the surface of carbon black have certain activities. At initial state, rubber chains with different lengths attach to the surface of Theory of sliding of molecular chains carbon black via physical adsorption. When the stress acts, rubber chains slide on the surface of CB particles, and the majority of chain segments elongated among the CB particles endure the stress. With the increase of the stress, rubber chains will continue to slide, make rubber chains highly oriented and promotes stress redistribution, thereby increasing the stress bore and modulus and stoping the molecular chains fracture caused by molecular chains concentration. Rubber compound shrank after the external force was revoked. After a long-time recovery, the adsorption and desorption reached a new dynamic balance because of thermal motion of rubber chains, which makes the lengths among carbon black particles and rubber compound chains redistributed, and rubber compound recovered or closed to the initial state. |

重新整理一下段落： Theory of sliding of molecular chains According to the theory of sliding of molecular chains, rubber chains that adsorb on the surface of carbon black have certain activities. At initial state, rubber chains with different lengths attach to the surface of carbon black via physical adsorption. When the stress acts, rubber chains slide on the surface of CB particles, and the majority of chain segments elongated among the CB particles endure the stress. With the increase of the stress, rubber chains will continue to slide, make rubber chains highly oriented and promotes stress redistribution, thereby increasing the stress bore and modulus and stoping the molecular chains fracture caused by molecular chains concentration. Rubber compound shrank after the external force was revoked. After a long-time recovery, the adsorption and desorption reached a new dynamic balance because of thermal motion of rubber chains, which makes the lengths among carbon black particles and rubber compound chains redistributed, and rubber compound recovered or closed to the initial state. |
