化学除氧中,采用联胺作为除氧剂有其优越性,不但除氧效果好,而且也适于钝化管道,抑制腐蚀。在高温高压试验回路中,温度和联胺量对除氧影响的试验表明,当温度为90℃,添加联胺量是系统除气后氧量的1.5-3倍时,可除去水中96—99%的氧量。从而确保回路处在低氧水质条件下安全运行。溶解氧的行踪试验为反应堆材料的防腐,提供了有用的数据。 Chemical deoxidation, the use of hydrazine as oxygen scavenger has its advantages, not only good oxygen scavenging effect, but also suitable for passivation pipe, inhibition of corrosion. In the high temperature and high pressure test circuit, the effect of temperature and amount of hydrazine on oxygen scavenging test showed that when the temperature is 90 ℃, the amount of hydrazine is added 1.5-3 times the amount of oxygen after degassing system can remove 96-99 % Of oxygen. This ensures safe operation of the circuit under low oxygen water conditions. The track of dissolved oxygen provides useful data for the preservation of reactor materials.
