腐蚀率的测试研究与实际应用的情况表明,多元醇磷酸酯缓蚀剂在腐蚀性水介质中,对碳钢具有良好的缓蚀效果。北京211厂长年使用有毒性的K_2Cr_2O_7作为该厂腐蚀性水介质中对碳钢、铝、不锈钢几种材质设备的缓蚀剂,致使环境污染和造成工人长年接触毒性药剂,因此,急待用无毒性的多元醇磷酸酯代替K_2CrO_7,缓蚀 Corrosion rate test research and practical application of the situation shows that the polyol phosphate corrosion inhibitor in a corrosive aqueous medium, carbon steel has a good corrosion inhibition. For many years, Beijing 211 Plant used poisonous K 2 Cr 2 O 7 as a corrosion inhibitor for several materials and equipment of carbon steel, aluminum and stainless steel in the corrosive aqueous medium of the plant, resulting in environmental pollution and long-term exposure of workers to toxic agents. Therefore, Non-toxic polyols phosphate instead of K_2CrO_7, corrosion inhibition
