一、试验研究目的未经硫化或硫化不佳的胶乳水泥模型材料具有明显的塑性,不仅易老化,强度低、且力学性能随时间和温度的变化大。胶乳水泥模型材料只有经过合适的硫化处理,才能变成良好的弹性材料,具有稳定的力学性能。因此,“硫化”对于胶乳水泥模型材料物理力学性能的 I. Purpose of the test The latex cement model material that has not been vulcanized or poorly vulcanized has obvious plasticity. It is not only easy to age, but also has low strength, and its mechanical properties vary greatly with time and temperature. The latex cement model material can be turned into a good elastic material only after proper vulcanization, and has stable mechanical properties. Therefore, “vulcanization” for the physical and mechanical properties of latex cement model materials
