一、硝铵厂房建筑结构腐蚀原因硝铵是一种氧化剂,在大气中吸收湿气或遇水溶解而成硝铵溶液,渗入混凝土与其中的盐类发生化学作用。这一过程随着温湿度的变化而不同。气温和湿度增高,加剧腐蚀。当大气中的湿度较大时,飞扬的硝铵粉尘便吸收大气中的水分而溶解渗入混凝土结构中起腐蚀作用。这种溶解腐蚀在黄梅季节尤为突出。在炎热或干燥季节,大气中湿度低,硝铵不易溶解,腐蚀速度则缓慢。其次,在同一楼层中的
First, ammonium nitrate plant corrosion causes of the building structure Ammonium nitrate is an oxidant, in the atmosphere to absorb moisture or ammonium nitrate solution dissolved in water, infiltration of concrete and the salt chemical. This process varies with temperature and humidity. Increased temperature and humidity, aggravating the corrosion. When the humidity in the atmosphere is large, the flying ammonium nitrate dust absorbs the moisture in the atmosphere and dissolves into the concrete structure to corrode. This dissolution is particularly prominent in the plum season. In hot or dry season, the humidity in the atmosphere is low, ammonium nitrate is not easy to dissolve, the corrosion rate is slow. Second, on the same floor
