High-conductivity grounding material for pressurized water reactor nuclear power unit and preparation method
The invention relates to a high-conductivity grounding material for a pressurized water reactor nuclear power unit and a preparation method thereof, and the high-conductivity grounding material comprises the following components in percentage by mass: 40-60% of bentonite, 20-44% of cement, 15-30% of electrolyte and 1-5% of additive. The grounding material has the long-acting conductive property, does not lose the mechanical strength of a conventional material, is simple in preparation process, low in cost and resistant to corrosion, does not need to be deliberately maintained in the later period, and can be used as a special functional grounding material to be applied to some engineering fields needing conductive corrosion resistance and difficult maintenance.
本发明涉及一种压水堆核电机组用高导电率接地材料及制备方法，按质量百分比计，包括膨润土40‑60％、水泥20‑44％、电解质15‑30％以及添加剂1‑5％。本发明的接地材料不仅具有长效导电性质，也不失常规材料的力学强度，且制备工艺简单，成本低廉，抗腐蚀，无需后期刻意养护，可作为特种功能接地材料应于某些需要导电耐腐蚀及维护困难工程领域。
