采用过桥齿轮传动实现从动型轮轴的退让，以保护价格较高的型轮部件；采用螺旋强制给料机构提高成型前物料的密度和可塑性，以保证型煤成品的强度；采用型槽与型齿对应配置的型窝，在获得同样强度的型球条件下降低成型压力，减小动力消耗。

In this study, room-temperature-vulcanized silicone rubber and high-temperature-vulcanized silicone rubber are use to prepare silicone composites. Silicone composites were prepared by adding different proportion of mica, silica or carbon fiber. The inorganic filler was thoroughly dispersed in silicone rubber by two-roll mill. This study focused on the influences of various fillers and additive level on the mechanical, thermal properties, anti-ablation and 90peel strength of the silicone hybrids.

中文摘要本实验分别选用室温熟成型矽橡胶以及高温熟成型矽橡胶作为高分子基材，再加入不同比例各种填充材料，例如：奈米云母、奈米二氧化矽、碳纤维等无机材料，并以双滚筒混炼法来制备矽橡胶复合混成材料，再经由其机械性质、耐烧蚀、黏著试验等量测，来探讨添加不同填充材及其添加量对矽橡胶热物性之影响。
