Low-resistance high-strength grounding material for pressurized water reactor nuclear power unit and preparation method
The invention discloses a low-resistance high-strength grounding material for a pressurized water reactor nuclear power unit and a preparation method. The grounding material comprises the following components in percentage by weight: 14-18% of cement, 37-46% of bentonite, 9-28% of aluminum powder, 15-19% of quartz sand and 6-8% of water. The metal aluminum is used as a conducting medium, the conductivity of the grounding material is greatly improved, the metal aluminum skeleton obtained through heat treatment is combined with the aggregate filled in the aluminum skeleton, the compression resistance and tensile strength of the grounding material are further improved, meanwhile, the toughness is also greatly improved, and the service life of the grounding material is prolonged. The method can be widely applied to thin-wall construction and heavy-load construction under the influence of physical and chemical environments such as heat loss and abrasion.
本发明公开了一种压水堆核电机组用低阻值高强度接地材料及制备方法，该接地材料按照重量百分比包括14～18％的水泥、37～46％的膨润土、9～28％的铝粉、15～19％的石英砂以及6～8％的水。本发明利用金属铝作为导电介质，极大地提高了接地材料的导电能力，通过热处理得到的金属铝骨架与铝骨架中填充的骨料相结合，进一步提高了接地材料的抗压、抗拉强度，同时强韧性能也得到大幅提高，可在热损、磨损等物理化学环境影响下的薄壁构建和重负载构建中得到广泛应用。
