In the rainy season of continuous plum rain, with the arrival of the rainy season, humid air comes along, which can cause varying degrees of damage to the goods and equipment facilities in the warehouse. Paper is particularly sensitive to air humidity, easily absorbing and losing moisture, causing wrinkles, tight edges, and ruffles, which can also affect the printing overlay standards.

Is there any way to reduce the humidity of the warehouse air? There are mainly the following measures:

Paper storage should be in a dry and clean environment, and should not be stacked tightly against walls;

If conditions permit, the relative humidity in the workshop and warehouse should be maintained between 50% and 60% as much as possible;

Humidity observation should also be conducted outside the warehouse. When the humidity inside the warehouse is high and exceeds 15 degrees outside, relevant measures such as opening ventilation windows and ducts should be taken in a timely manner for ventilation. Otherwise, the warehouse should be tightly closed;

Warehouses with exhaust fans should keep the fans turned on; For small warehouses, powerful fans can be turned on to enhance the convection of air inside the warehouse and reduce the condensation of water droplets.

Because water vapor in the air can easily condense into water droplets when it comes into contact with small particles, it is necessary to clean the warehouse with a dry cloth or mop to keep the floor and goods clean and reduce the formation of surface water droplets.

Lime is an adsorbent, and 1 kilogram of quicklime can adsorb approximately 0.3 kilograms of moisture in the air; It can also be left unused or wrapped in quicklime in burlap bags and placed in various places inside the warehouse to keep the indoor air dry.

The stacked cardboard boxes should not be too dense and should be as loose as possible. If they are too tight, air convection will be severely restricted, and humid air will accumulate for a long time without dispersing, which can easily produce mold.

It is recommended not to cover with a thin film to prevent water droplets, as it is impossible to achieve complete sealing. There will still be a large amount of water vapor under the film, and the formed water droplets are difficult to evaporate due to being covered by the film, which can lead to mold.
