In the process of ocean transportation or storage, containers often experience high temperature climate and strong diurnal temperature difference. The temperature change will be 0-8 ℃ and the humidity will be as high as 98%. This is the condensation phenomenon. When the temperature is 30 ℃, the water content in the air is 30.4g per square meter. When the temperature drops from 30 ℃ to 18 ℃, the water vapor will condense into water droplets. If it is a 40 foot container, it will produce 1000 grams of condensed water, which will cause "container rain".

工地集裝箱的水取決于天氣狀況，海運航程的長短，貨物包裝材料、集裝箱狀況以及貨物的敏感度等。真菌、霉菌、霉在相對濕度超過55%時會對貨物造成損壞。

The water content of the site container depends on the weather conditions, the length of the sea voyage, the packaging materials of the goods, the condition of the container and the sensitivity of the goods. Fungi, molds and molds will damage the goods when the relative humidity exceeds 55%.

集裝箱里面有水主要可分以下幾種情況：貨物自帶、箱體凝結、海水入浸、淡水入浸

There is water in the container, which can be divided into the following situations: goods brought, condensation, seawater immersion, fresh water immersion
             

1、貨物自帶

1. Bring your own goods

濕氣或水分隨貨物一起被帶入集裝箱。舉個例來說，如果一個集裝箱內裝了5噸的家具，家具本身就會含有大概8%到25%的濕度，根據(jù)木材類型、家具干燥處理程度的不同而有所不同。這相當于大約400-1250升的水。這里邊的濕氣有些就會散發(fā)到集裝箱內的空氣中，成為集裝箱水汽凝結的一個重要來源。

Moisture or moisture is carried into the container with the cargo. For example, if a container contains 5 tons of furniture, the furniture itself will contain about 8% to 25% humidity, depending on the type of wood and the degree of drying. That's about 400-1250 liters of water. Some of the moisture will be sent out to the air inside the container, and become an important source of water vapor condensation in the container.

2、箱體凝結

2. Box condensation

在輕鋼活動房遠洋運輸或存儲過程中，貨柜往往會經(jīng)歷高溫氣候及較強的晝夜溫差變化，溫度變化會在0-8攝氏度，濕度會高達98%，這就是凝露現(xiàn)象，當溫度為30度時，空氣中水含量為30.4g每。當溫度由30攝氏度降低到18攝氏度，水蒸氣就會凝結成水滴，若是40英尺貨柜則產(chǎn)生1000克的冷凝水，就會造成“集裝箱雨”。

In the process of ocean transportation or storage of light steel mobile house, containers often experience high temperature climate and strong diurnal temperature difference. The temperature change will be 0-8 ℃ and the humidity will be as high as 98%. This is condensation phenomenon. When the temperature is 30 ℃, the water content in the air is 30.4g per square meter. When the temperature drops from 30 ℃ to 18 ℃, the water vapor will condense into water droplets. If it is a 40 foot container, it will produce 1000 grams of condensed water, which will cause "container rain".
