摘要: 对核电站广泛使用的电缆防火涂料和有机防火堵料进行了耐γ辐射的研究。结果表明:1000kGy以上的γ辐射能严重恶化电缆防火涂料的抗弯性、耐湿热性、耐冷热循环性。500kGy以上的γ辐射对有机防火堵料的耐火性和腐蚀性都有很大影响。

Abstract: In order to guarantee the fire safety of nuclear power plants, we have studied the radio resistance of two kinds of fireproof materials—the cable fireproof coating and organic fireproof putty, which are widely used in nuclear power stations. The results indicate that the γ-ray over 1000 kGy can seriously deteriorates the bending-resistance performance, the wet-resistance and heat-resistance, the cold-resistance and heat-resistance performances of the cable fireproof coating. The γ-ray over 500 kGy not only possess great effects on the corrosion performance of the organic fireproof putty but decreases the fireproof capability greatly.
