Calcium Chloride Desiccant Can Solve The Container Moisture Problem

Oct 13, 2017

Absolute humidity refers to the actual volume of water vapor per unit volume of wet air.

Saturated humidity refers to a certain pressure and a certain temperature conditions, the unit volume of air can contain water vapor limit value.

Relative humidity (RH), refers to the air vapor pressure and saturated vapor pressure percentage, it can be said that the absolute humidity of wet air and the same temperature may reach the saturation humidity ratio.

Relative humidity = absolute humidity / saturation humidity × 100%

 When the temperature is 30 ℃, the relative humidity of 98%, when the water content of about 30.4g / m3, when the temperature from 30 ℃ to 18 ℃, the water vapor content will drop to 15.4 g / m3, then The excess water vapor in the container temperature is relatively low on the inner wall of condensed into water droplets, this condensed water droplets if the product will be directly on the product caused by moldy deterioration. This condensation of water droplets we commonly known as "container rain", the image of the packaging will cause a very negative impact, so need to place a certain amount of container desiccant to solve the problem. Understand the relevant goods humid common sense, fundamentally clear the reasons for its formation, to be able to protect our goods from moisture invasion, safe arrival at the port of destination.
