High-aluminum composite conductive grounding material for pressurized water reactor nuclear power unit and preparation method of high-aluminum composite conductive grounding material
The invention discloses a high-aluminum composite conductive grounding material for a pressurized water reactor nuclear power unit and a preparation method of the high-aluminum composite conductive grounding material. The grounding material comprises the following components in percentage by mass: 12-35% of cement, 25-45% of boiler coal ash, 10-22% of aluminum powder, 8-15% of graphite powder, 12-18% of water and 1-4% of sodium polyphosphate. The method is characterized in that a composite conductive filler consisting of metal aluminum powder and graphite powder is added as a conductive phase, and meanwhile, boiler coal ash is taken as one of components, so that the difficult problem of treating combustion products of a coal-fired boiler is solved, and the environmental pollution is reduced. The high-aluminum composite conductive grounding material for the pressurized water reactor nuclear power unit is low in resistivity, high in compressive strength, excellent in corrosion resistance, simple in production process, flexible to operate, low in cost and wide in applicability.
本发明公开了一种压水堆核电机组用高铝复合型导电接地材料及其制备方法，该接地材料按照质量百分比包括12～35％的水泥、25～45％的锅炉煤灰、10～22％的铝粉、8～15％的石墨粉、12～18％的水以及1～4％的多聚磷酸钠；其特征是加入了由金属铝粉+石墨粉组成的复合导电填料作为其导电相，同时以锅炉煤灰作为组分之一解决了燃煤锅炉燃烧产物的处理难题，减少了环境污染。本发明的一种压水堆核电机组用高铝复合型导电接地材料电阻率低、抗压强度高、耐蚀性优异，生产工艺简单、操作灵活、成本低廉，适用性广。
