With the advent of rainy season, it is much more cloudy and rainy than sunny and cloudless. How can we control the humidity of storehouses and prevent dampness of storehouses?
That is to say, close the goods as tightly as possible, and reduce the impact of the bad weather conditions on the goods, so as to achieve the purpose of safe storage. Using the sealing method, it should be used in combination with ventilation and moisture absorption, such as the use of proper method, such as moistureproof, mildew proof, heat prevention, anti melting, anti dry cracking, antifreeze, rust prevention and insect proof and so on.
Ventilation is the use of air temperature difference between the inside and outside the library to form a pressure difference, so that the air inside and outside the warehouse to form convection, so as to achieve the purpose of regulating the temperature and humidity inside the reservoir. The greater the temperature difference between inside and outside, the faster the air flows; if there is wind outside the warehouse, the pressure of the wind can speed up the convection of the air inside and outside the library. But the wind can not be too big (the wind is more than 5, and the dust is more). Proper ventilation can not only regulate and improve the temperature and humidity in the storehouse, but also distribute the excess moisture of goods and packages in time. According to the different purposes of ventilation, it can be divided into two types: ventilation and cooling (or warming) and ventilation.
In the Meiyu season or the rainy day, when the humidity is too high in the reservoir, it is not suitable for the storage of the goods, and the humidity is too large outside the library. When the ventilation is not suitable to be carried out, the moisture absorption can be reduced in the sealed storehouse.
With the continuous development of market economy, modern warehouse stores generally use mechanical moisture absorption methods. Dehumidifier is used to remove moisture from the air through the dehumidifier in the warehouse, and the air becomes dry.
