三、库房的温湿度管理影响金属锈蚀的自然因素,主要是水分和氧气。在正常的库房保管条件下,金属商品是否发生电化学锈蚀和锈蚀的程度如何,决定于空气中含水蒸气多少,主要看空气的相对湿度大小,而不是绝对湿度的大小。温度与金属锈蚀的速度有关,当相对湿度在金属能发生锈蚀的临界湿度以上时,温度越高,锈蚀越快。温度提高10℃,锈蚀速度提高约两倍。 Third, the warehouse temperature and humidity management The natural factors that affect the metal corrosion, mainly water and oxygen. In the custody of the normal warehouse conditions, the electrochemical corrosion of metal goods and rust extent, depending on how much water vapor in the air, mainly to see the relative humidity of air size, rather than the absolute size of the humidity. The temperature is related to the rate of metal corrosion. When the relative humidity is above the critical humidity at which the metal can corrode, the higher the temperature, the faster the corrosion. The temperature increased by 10 ℃, the corrosion rate increased about twice.
