护环法在钢筋混凝土体系腐蚀评价中的可行性研究

In addition, the corrosion deposits on the packings and ring plate would lead to under-deposit corrosion.

同时, 不锈钢填料和边缘板上的腐蚀沉积物会引发局部垢下腐蚀.

Third, the PTFE ( F 4 ) of the corrosion seal ring.

第三, 聚四氟乙烯 ( F4 ) 密封环的腐蚀.

Spot evaluation test, which was carried out by the method of corrosion test ring, results show: composite inhibitor is consistent to saturated saltwater drilling fluids, its inhibition efficiency is about 90%.

运用腐蚀试验环法进行现场评价试验，结果表明：该复合缓蚀剂和饱和盐水钻井液配伍性良好，现场缓蚀率达到90%左右，效果明显。
