摘要 描述了安全混合物注射成型策略的概要。建议在机器条件下使用安全促进剂、安全固化系统和混合物，从而为各种产品提供较短的固化时间。对在相同温度下、在相同模具和压力机中由相同混合物制备的注射和压缩成型品的硫化橡胶性能进行了比较。结果表明，虽然各向异性在注射成型中更为明显，但最佳模量固化的沿径向模具流动线和与径向模具流动线成 90° 的模量平均值与同样固化至其最佳模量的压缩成型中沿研磨流动线和与研磨流动线成 90° 的模量平均值相同（在实验误差内）。注塑成型在体积膨胀和硬度方面与压缩成型相似，但它们具有稍高的回弹性和稍低的压缩永久变形。模具温度升高的效果是提供有价值的...
Abstract The outline of a strategy for the injection molding of a safe mix is described. Safe accelerators, safe curing systems, and mixes are suggested with machine conditions which should yield short curing times for a wide range of products. Comparisons have been made of the vulcanizate properties of injection and compression moldings prepared from the same mix in the same mold and press at the same temperature. Results have shown that, although anisotropy is more pronounced in injection moldings, the mean of values for modulus along and at 90° to radial mold flow lines of an optimum modulus cure are the same (within experimental error) as the mean of values for modulus along and at 90° to mill flow lines in a compression molding also cured to its optimum modulus. Injection moldings are similar to compression moldings in volume swelling and hardness but they have marginally higher rebound resilience and marginally lower compression set. The effect of an increase in mold temperature is to give a valuabl...
