Are the goods stored in the warehouse damp or moldy? It means that the storage environment of the goods is very humid and it is necessary to check the source of moisture:

First of all, you need to check: the waterproofing of the roof, wall, and ground, is there any water ingress or water seepage?

In particular, pay attention to whether the roof leaks. The steel structure roof is usually made of colored steel plates, supplemented by lighting windows, ventilators, and other components.

These materials usually use silicone sealant, water-stop tape, and other materials for filling and waterproof plugging at the connection. However, since the sealant is an embedded seal, the effect cannot be absolutely guaranteed. On the one hand, if there is looseness, sliding, or vibration deformation between the metal plates, new cracks will appear in the seal. At the same time, the anti-aging ability of the sealant is poor and the service life is short.

If there are no problems in those aspects, that is, the air contains moisture, mechanical forced ventilation should be adopted, dehumidifiers should be installed, and hygroscopic materials should be placed;

Check the ventilation and lighting effect of the warehouse. The warehouse where the goods are stored must ensure a good ventilation and lighting effect. According to the situation, judge whether the ventilation, lighting, and other facilities of the warehouse need to be adjusted.
