【摘要】 用挂片失重法测定了次氯酸钠水溶液对碳钢、铜和铝的腐蚀性,葡萄糖酸钠、水杨酸钠和多元醇磷酸酯类缓蚀剂(PC-602)的缓蚀效果及其对次氯酸钠分解率的影响。含有效氯浓度250ppm的次氯酸钠溶液,加入150～250ppm PC-602,对碳钢的缓蚀率可达92～94%。PC-602对次氯酸钠的稳定性无影响,葡萄糖酸钠和水杨酸钠复配具有协同增效作用.但可加速次氯酸钠的分解速率。次氯酸钠溶液对铜和铝两种金属的腐蚀性较小。更多还原

【Abstract】 The corrosion of an aqueous solution of sodium hypochlorite on carbon steel,copper and aluminium and the corrosion inhibition of sodium gluconate.Sodium salicylate and polyhydric alcohol phosphate ester (PC-602) inhibitors and their influence on the decom- position of sodium hbypochlorite have been studied by the weight loss method. With 250ppm sodium hypochlorite solution containing 150～250 ppm PC-602, the inhibition efficiency may reach 92%～94%.For PC-602,there are no influence on the stability of sodium salicylate can be accelerate the rate of decomposition of sodium hypochlorite.更多还原
