背景技术Background technique
随着人们日益关注环境和能源问题，使用非常规燃料的新能源汽车因其对环境相对友好、能源来源多样化而收到人们的追捧。纯电动汽车以其零污染、低噪音，能源利用效率高的优势在整个新能源汽车行业中的脱颖而出。虽然目前纯电动汽车在环保和节能上有不可比拟的优势，但是动力电池的技术瓶颈始终制约着整车的发展。动力电池在当前技术水平的局限下，只能在如成本、容量、功率、循环寿命、热特性等各种特性指标中做均衡和取舍。As people pay more and more attention to environmental and energy issues, new energy vehicles using unconventional fuels have been sought after by people because of their relative friendliness to the environment and diversification of energy sources. Pure electric vehicles stand out in the entire new energy vehicle industry with their advantages of zero pollution, low noise, and high energy utilization efficiency. Although pure electric vehicles have incomparable advantages in environmental protection and energy saving, the technical bottleneck of power batteries has always restricted the development of complete vehicles. Under the limitation of the current technical level, the power battery can only make balance and trade-offs among various characteristic indicators such as cost, capacity, power, cycle life, and thermal characteristics.
一般，为了降低纯电动车的成本及满足一定的续航里程通常会选用小成本大容量的动力电池，然而这种动力电池的功率性能较差，大倍率放电对动力电池电芯的寿命影响较大。为了解决上述问题实现一定的加速动力，通常采用高功率的电芯的动力电池，但是这种动力电池不仅成本高，容量也较小，单次充电的续驶里程很短。Generally, in order to reduce the cost of pure electric vehicles and meet a certain cruising range, power batteries with low cost and large capacity are usually selected. However, the power performance of such power batteries is poor, and high-rate discharge has a greater impact on the life of power battery cells. . In order to solve the above problems and achieve a certain acceleration power, a power battery with high-power cells is usually used, but this kind of power battery not only has high cost, but also has a small capacity, and the mileage of a single charge is very short.

为了有效的利用固化桶的容积，桶外搅拌是一种较好的选择，但是在桶外搅拌工艺的使用过程中对水泥固化配方提出了特殊的要求，那就是水泥固化配方必须保证水泥浆有足够的流动性，这样才能保证在搅拌完成后的卸料顺利完成，同时树脂本身的密度比水泥浆轻，水泥固化配方必须保证水泥浆较快的开始凝固避免树脂在水泥浆中出现分层现象而破坏均匀性。In order to effectively utilize the volume of the curing tank, mixing outside the tank is a better choice, but in the process of using the mixing process outside the tank, special requirements are put forward for the cement curing formula, that is, the cement curing formula must ensure that the cement slurry has Sufficient fluidity, so as to ensure the smooth completion of unloading after the mixing is completed. At the same time, the density of the resin itself is lighter than that of the cement slurry. The cement curing formula must ensure that the cement slurry starts to solidify quickly to avoid the layering of the resin in the cement slurry. and destroy the uniformity.
放射性废树脂在进行水泥固化处理前都临时贮存在容器中，且为了便于树脂的回取都需要用水浸泡树脂，为了能精确的计量树脂，通过机械旋转脱水来去除树脂上的游离水，之后称量树脂的重量，可以得到较准确的剂量。因此在配方研发过程中采用脱水树脂进行配方研发。The radioactive waste resin is temporarily stored in the container before the cement curing treatment, and in order to facilitate the retrieval of the resin, it is necessary to soak the resin in water. In order to accurately measure the resin, the free water on the resin is removed by mechanical spin dehydration, which is called Measure the weight of the resin to get a more accurate dosage. Therefore, in the process of formula development, dehydrating resin is used for formula development.
