It is well known that container shipping is a very safe and economical way of transportation of many goods, and also a favorite way for exporters. However, many customers who use container shipping have been complained and even returned goods repeatedly due to the dampness of the goods during shipping, resulting in losses of tens of thousands or even millions. What's more, the goods were required to be destroyed on the spot by the local customs due to mildew, which caused great losses! At this time, many people will wonder how the goods can be damped when they are loaded into tightly sealed containers. Where does the moisture come from? The root cause is that there is no effective moisture-proof scheme for container containers

Through containers, also known as dry containers, are mainly used to ship groceries, and are usually used to ship textiles, handicrafts, chemical products, hardware and electrical equipment, electronic machinery, instruments and machine parts, as well as cultural goods, daily necessities, medical supplies, etc. This kind of container container accounts for 70~80% of the total number and is widely used

However, both products with low water content, such as metal accessories, hardware accessories, electronic products, etc; Or goods with high water content, such as rice, tea, corn, paper products, etc., are transported to various parts of the world by container shipping. Due to the high humid climate of the sea and the large temperature difference between day and night, the problem of moisture and mildew often occurs. For this reason, goods stored in sea containers for export are far more vulnerable to moisture than those placed in land warehouses

Container dehumidifier, moisture-proof scheme for container shipping

According to the relevant survey data,

1) 70% of the containers tested had moisture content 14% higher than the standard value

2) The average value of moisture is 18% to 20%

3) About 30% of the containers, with more than 25% moisture

It is understood that the reason why the goods are affected with moisture during the shipping of container containers is that:

1) The goods come out of water: when the goods are transported from low temperature areas to high temperature areas, or when the goods storage environment suddenly changes from cold to hot, the water vapor in the air will condense into water on the surface of the goods or their packaging, and the goods themselves will also come out of water

2) Container rain: container rain - when a container enters a low temperature area from a high temperature area, its internal ambient temperature changes from a high temperature to a low temperature and reaches the dew point temperature, the water vapor will condense into water droplets, which will condense on the top of the container and on the inner walls around it, and finally drop onto the arrival

What is "container rain"? It is not uncommon for the temperature in container containers to change around 30 ℃ during sea transportation. The container container is exposed to tropical sunlight during the day, and the temperature will reach 60 ℃, so the high temperature air contains a lot of water. The temperature will drop at night. Since high temperature air can carry more water than low temperature air, once the temperature drops, it is clear that the air with high temperature and water content in the daytime will have some water vapor attached to objects with lower temperature such as the side walls of containers and the inner surfaces of goods in the form of condensed water at night, which is commonly known as "containers like rain"

When this "container rain" keeps dropping on the goods, not only will the outer packaging of the goods soften and the labels fall off, but also your export goods will inevitably suffer from mildew and decay, such as metal rust, wood mildew and poor texture, rice and agricultural products deterioration and mildew. Once it is found that the goods are damp and mouldy during long distance sea transportation, it should not be ignored. Whether it is domestic long distance transportation or export ocean container transportation, corresponding moisture-proof measures should be taken in the cabinet to resist the threat caused by container rain or goods sweating. So, is there any way to solve the problem of dampness

The solution is: fear that your export goods will become damp and moldy? Then use the dehumidifier to quickly dehumidify and control the humidity in the container in real time. It may not cost too much money for the first time, but in the long run, if every container of goods has problems of one kind or another, it is believed that every customer will not want to see it for a long time. In a word, the use cost of dry dehumidifier is not high, far less than the goods themselves. Low cost is used to protect goods, which is a very effective solution for container shipping moisture-proof

[Requirements for dehumidifier leasing] The lease starting conditions for dehumidifiers are: the number of leased dehumidifiers is ≥ 5, and the lease term is ≥ 30 days

[Dehumidifier rental charging standard] 80-150 yuan/set/day (the price can be determined according to the rental model, rental quantity and rental days)

◎ Precautions for model selection -- The dehumidification capacity and model of dehumidifier are scientifically calculated mainly according to the volume of the used environment space, the size of fresh air volume, the humidity requirements required by the space environment and other specific values. In addition, it should be noted that the relative humidity of the environment is related to the temperature of the environment. The higher the temperature is, the faster the humidity will evaporate. On the contrary, the worse the effect will be. Therefore, when configuring the dehumidifier, you need to select the type under the guidance of professionals, so that you can select the dehumidifier that is most suitable for you

Core tips: container containers are used according to their actual needs_ The container dehumidifier and Parkoo series full-automatic moisture-proof dehumidifier are used for moisture-proof and moisture absorption, reducing and controlling the humidity inside the container, effectively controlling the dew point, avoiding visible and hidden condensation, ensuring that the internal climate environment of the container is always in a dynamic and balanced dry state, solving the problem of goods being wet and moldy during long distance, so as to protect the safe and dry arrival of goods at the destination. This method is not only highly feasible, And it is the simplest and relatively low cost, which is worth promoting and applying vigorously
