Structure and Properties of Ebonite

硬质橡胶的结构与性能

Ebonite fixed wide wheel industrial caster .

硬橡胶固定肥仔轮。

The results showed that the crosslink structure in SBR ebonite compound was predominant at the early stage of vulcanization ;

结果表明，在硫化反应前期，硬质SBR胶料中交联结构起主导作用；

And as the curing time extended , the hardness , tensile strength and elastic modulus of SBR ebonite increased and its T_g rose significantly .

随着硫化时间的延长，硬质SBR的硬度、拉伸强度及弹性模量增大，玻璃化温度显著提高。

Ebonite & Determination of cross-breaking strength

GB/T1696-1981硬质橡胶横向折断强度的测定方法

The crosslink structure reduced , and the modification of rubber by polar sulfur ring was predominant resulting in plastics-like SBR ebonite at the middle and final stages of vulcanization ;

在硫化反应中后期，胶料中交联结构减少，极性的硫环分子对橡胶改性起主导作用，从而形成具有塑料性质的硬质SBR；
