Структурний склад гумової продукції

Лінійна структура:The general structure of unvulcanized rubber. Due to its large molecular weight, it is a fine clump without external force. When the external force is removed, the entanglement of the fine mass changes, and the molecular chain rebounds, resulting in a strong recovery tendency, which is the origin of the high elasticity of rubber.

Структура розгалуженої ланцюга:The branching of the rubber macromolecular chain is aggregated to form a gel. Gels are not good for the performance and processing of rubber. In the process of rubber mixing, various compounding agents often improve the gel area, form a local blank, and cannot form reinforcement and cross-linking, which becomes the weak part of the product.

Зшита структура:Linear molecules are connected to each other by the bridging of some atoms or clusters of atoms to form a three-dimensional network structure. This structure is strengthened as the vulcanization process progresses. In this way, the free mobility of the segments decreases, the plasticity and elongation decrease, the strength, elasticity and hardness increase, and the compression set and swelling зменшити .
